Definitions.

(1) Air-purifying respirator (APR) means a respirator equipped with an air-purifying element such as a filter, cartridge, or canister, OR having a filtering facepiece, for example, a dust mask. The element or filtering facepiece is designed to remove specific contaminants, such as particles, vapors, or gases, from air that passes through it.
(2) Air-line respirator means an atmosphere-supplying respirator for which breathing air is drawn from a source separate from and not worn by the user, such as:
• A cylinder or a tank;
• A compressor;
• An uncontaminated environment.
(3) Air supplied respirator (see air-line respirator).
(4) Assigned protection factor (APF) indicates the workplace level of respiratory protection that a respirator or class of respirators is expected to provide to employees when you implement a continuing, effective respiratory protection program as specified by this chapter. For example, an effective program makes sure the respirator is:
• Functioning properly;
• Fitted to the user;
• Worn by trained individuals; and
• Used with the limitations specified on the NIOSH-approval label.
(5) Atmosphere-supplying respirator means a respirator that supplies the user with breathing air from sources, such as:
• A cylinder or a tank;
• A compressor;
• An uncontaminated environment.
(7) Canister or cartridge (air-purifying) is part of an air-purifying respirator that consists of a container holding materials such as fiber, treated charcoal, or a combination of the two, that removes contaminants from the air passing through the cartridge or canister.
(8) Cartridge respirator (see also air-purifying respirator) means an air-purifying respirator equipped with one or more cartridges. These respirators have a facepiece made from silicone, rubber OR other plastic-like materials.
(9) Demand respirator means an atmosphere-supplying respirator that sends breathing air to the facepiece only when suction (negative pressure) is created inside the facepiece by inhalation. Demand respirators are "negative pressure" respirators.
(10) DOSH means the division of occupational safety and health, located in the department of labor and industries.
(11) Dust mask is a name used to refer to filtering-facepiece respirators. Dust masks may or may not be NIOSH certified. See filtering facepiece.
(12) Emergency respirator means a respirator suitable for rescue, escape, or other activities during emergency situations.
(13) Emergency situation means any occurrence that could or does result in a significant uncontrolled release of an airborne contaminant. Causes of emergency situations include, but are not limited to, equipment failure, rupture of containers, or failure of control equipment.
(14) End-of-service-life indicator (ESLI) is a system that warns the air-purifying respirator user that cartridges or canisters must be changed. An example of an ESLI is a dot on the respirator cartridge that changes color.
(15) Escape-only respirator is a respirator that can only be used to exit during emergencies. Look for this use limitation on the respirator's NIOSH approval label.
(16) Exposed, or exposure means the contact an employee has with a toxic substance, harmful physical agent, or oxygen deficient condition. Exposure can occur through various routes of entry, such as inhalation, ingestion, skin contact, or skin absorption.
(17) Filter means fibrous material that removes dust, spray, mist, fume, fog, smoke particles, OR other aerosols from the air.
(18) Filtering-facepiece respirator means a tight-fitting, half-facepiece, negative-pressure, particulate air-purifying respirator with the facepiece mainly composed of filter material. These respirators do not use cartridges or canisters and may have sealing surfaces composed of rubber, silicone or other plastic-like materials. They are sometimes referred to as "dust masks."
(19) Fit factor is a number providing an estimate of fit for a particular respiratory inlet covering to a specific individual during quantitative fit testing.
(20) Fit test (see also qualitative fit test and quantitative fit test) is an activity where the facepiece seal of a respirator is challenged, using a DOSH accepted procedure, to determine if the respirator provides an adequate seal.
(21) Full-facepiece respirator means a tight-fitting respirator that covers the wearer's nose, mouth, and eyes.
(22) Gas mask means an air-purifying respirator equipped with one or more canisters. These respirators have a facepiece made from silicone, rubber OR other plastic-like materials.
(23) Half-facepiece respirator is a tight-fitting respirator that only covers the wearer's nose and mouth.
(24) Helmet means the rigid part of a respirator that covers the wearer's head AND also provides head protection against impact or penetration.
(25) High-efficiency particulate air filter (HEPA) is a powered air-purifying respirator (PAPR) filter that removes at least 99.97% of monodisperse dioctyl phthalate (DOP) particles with a mean particle diameter of 0.3 micrometer from contaminated air.
Note:
Filters designated, under 42 C.F.R. Part 84, as an "N100," "R100," or "P100" provide the same filter efficiency (99.97%) as HEPA filters.
(26) Hood is the part of a respirator that completely covers the wearer's head and neck AND may also cover some or all of the shoulders and torso.
(27) Immediately dangerous to life or health (IDLH) means an atmospheric condition that would:
• Cause an immediate threat to life; or
• Cause permanent or delayed adverse health effects; or
• Interfere with an employee's ability to escape.
(28) Licensed health care professional (LHCP) means an individual whose legally permitted scope of medical practice allows him or her to provide some or all of the health care services required for respirator users' medical evaluations.
(29) Loose-fitting facepiece is a respiratory inlet covering that is designed to form a partial seal with the face.
(30) Negative-pressure respirator means any tight-fitting respirator in which the air pressure inside the facepiece is less than the air pressure outside the respirator during inhalation.
(31) NIOSH is the National Institute for Occupational Safety and Health. NIOSH is the federal agency that certifies respirators for occupational use.
(32) Oxygen deficient is an atmosphere with an oxygen content below 19.5% by volume.
(33) Permissible exposure limits (PELs) are employee exposures to toxic substances or harmful agents that must not be exceeded. PELs are specified in applicable DOSH chapters.
(34) Positive-pressure respirator means a respirator in which the air pressure inside the respiratory inlet covering is greater than the air pressure outside the respirator.
(35) Powered air-purifying respirator (PAPR) means an air-purifying respirator equipped with a blower that draws ambient air through cartridges or canisters. These respirators, as a group, are not classified as positive pressure respirators and must not be used as such.
(36) Pressure-demand respirator means a positive-pressure atmosphere-supplying respirator that sends breathing air to the respiratory inlet covering when the positive pressure is reduced inside the facepiece by inhalation or leakage.
(37) Qualitative fit test (QLFT) is a test that determines the adequacy of respirator fit for an individual. The test relies on the employee's ability to detect a test substance. Test results are either "pass" or "fail."
(38) Quantitative fit test (QNFT) is a test that determines the adequacy of respirator fit for an individual. The test relies on specialized equipment that performs numeric measurements of leakage into the respiratory inlet covering. Test results are used to calculate a "fit factor."
(39) Required use is respirator use that:
• Is necessary to protect employees from respiratory hazards; or
• The employer decides to require for his or her own reasons. For example, the employer decides to follow more rigorous exposure limits.
(40) Respirator is a type of personal protective equipment designed to protect the wearer from airborne contaminants, oxygen deficiency, or both.
(41) Respiratory hazard means airborne hazards and oxygen deficiency that are addressed in chapter 296-841 WAC, Airborne contaminants.
(42) Respiratory inlet covering is the part of a respirator that forms the protective barrier between the user's respiratory tract and an air-purifying device or breathing air source or both. The respiratory inlet covering may be a facepiece, helmet, hood, suit, or mouthpiece respirator with nose clamp.
(43) Seal check means actions conducted by the respirator user each time the respirator is put on, to determine if the respirator is properly seated on the face.
(44) Self-contained breathing apparatus (SCBA) is an atmosphere-supplying respirator designed for the breathing air source, to be carried by the user.
(45) Service-life means the period of time that a respirator, filter or sorbent, or other respiratory equipment provides adequate protection to the wearer. For example, the period of time that sorbent cartridge is effective for removing a harmful substance from the air.
(46) Sorbent means rigid, porous material, such as charcoal, used to remove vapor or gas from the air.
(47) Supplied-air respirator (see air-line respirator).
(48) Tight-fitting facepiece is a respiratory inlet covering forming a complete seal with the face OR neck. Mouthpiece respirators are not tight-fitting facepieces.
(49) Voluntary use means respirator use that is requested by the employee and permitted by the employer when no respiratory hazard exists.

296-842-10505
Designate a program administrator.

Exemption:
You do not need to designate a program administrator if employees use only filtering-facepiece respirators and do so only as voluntary use.
[Statutory Authority: RCW 49.17.050 and 29 C.F.R. Subpart Z. WSR 09-19-119, § 296-842-10505, filed 9/22/09, effective 12/1/09. Statutory Authority: RCW 49.17.010, 49.17.040, 49.17.050, 49.17.060. WSR 07-05-072, § 296-842-10505, filed 2/20/07, effective 4/1/07; WSR 03-20-114, § 296-842-10505, filed 10/1/03, effective 1/1/04.]



296-842-11005
Make sure voluntary use of respirators is safe.

IMPORTANT:
• Respirator use is not voluntary, and the required use sections of this chapter apply, if:
– An employer chooses to require respirator use.
– Some requirements in this section do not apply if only filtering-facepiece respirators are used voluntarily.
– Some filtering-facepiece respirators are equipped with a sorbent layer for absorbing "nuisance" organic vapors. These can be used for voluntary use, but are not NIOSH certified for protection against hazardous concentrations of organic vapor.
(1) Make sure voluntary respirator use does NOT:
(a) Interfere with an employee's ability to work safely, such as restricting necessary vision or radio communication;
or
(b) Create health hazards.
Note:
Examples of health hazards include:
 
• Skin irritation, dermatitis, or other health effects caused by using a dirty respirator.
 
• Illness created by sharing contaminated respirators.
 
• Health effects caused by use of an unsafe air supply, such as carbon monoxide poisoning.
(2) Provide all voluntary respirator users with the advisory information in Table 2 at no cost to them.
(3) Develop and maintain a written program that includes the following:
(a) Medical evaluation provisions as specified in WAC 296-842-14005.
(b) Procedures to properly clean and disinfect respirators, according to WAC 296-842-22015, if they are reused.
(c) How to properly store respirators, according to WAC 296-842-17010, so that using them does not create hazards.
(d) Procedures to make sure there is a safe air supply, according to WAC 296-842-20010, when using air-line respirators and SCBAs.
(e) Effective training to ensure respirator use does NOT create a hazard.
Exemption:
If employees use only filtering-facepiece respirators and do so only voluntarily, you do not need to develop and maintain a written program.
(4) Use Table 2 to provide information to employees who voluntarily use any type of respirator.
Table 2
Advisory Information for Employees Who Voluntarily Use Respirators
• Respirators protect against airborne hazards when properly selected and used. Respirator usage that is required by DOSH or your employer is not voluntary use. With required use, your employer will need to provide further training and meet additional requirements in this chapter. DOSH recommends voluntary use of respirators when exposure to substances is below DOSH permissible exposure limits (PELs) because respirators can provide you an additional level of comfort and protection.
• If you choose to voluntarily use a respirator (whether it is provided by you or your employer) be aware that respirators can create hazards for you, the user. You can avoid these hazards if you know how to use your respirator properly AND how to keep it clean. Take these steps:
 
– Read and follow all instructions provided by the manufacturer about use, maintenance (cleaning and care), and warnings regarding the respirator's limitations.
 
– Choose respirators that have been certified for use to protect against the substance of concern. The National Institute for Occupational Safety and Health (NIOSH) certifies respirators. If a respirator is not certified by NIOSH, you have no guarantee that it meets minimum design and performance standards for workplace use.
 
 
■ A NIOSH approval label will appear on or in the respirator packaging. It will tell you what protection the respirator provides.
 
– Keep track of your respirator so you do not mistakenly use someone else's.
 
do not wear your respirator into:
 
 
■ Required use situations when you are only allowed voluntary use.
 
 
■ Atmospheres containing hazards that your respirator is not designed to protect against.
 
 
 
For example, a respirator designed to filter dust particles will not protect you against solvent vapor, smoke or oxygen deficiency.

296-842-11010
Keep voluntary use program records.

Exemption:
If employees use only filtering-facepiece respirators voluntarily, you do not need to follow these recordkeeping requirements.
(1) Keep copies of:
(a) Your current written respirator program
(b) Written recommendations from the licensed health care professional (LHCP)
(2) Allow records required by this section to be examined and copied by affected employees and their representatives.
Reference:
See chapter 296-802 WAC, Employee medical and exposure records, for additional requirements that apply to medical records.
[Statutory Authority: RCW 49.17.010, 49.17.040, 49.17.050, 49.17.060. WSR 07-05-072, § 296-842-11010, filed 2/20/07, effective 4/1/07; WSR 03-20-114, § 296-842-11010, filed 10/1/03, effective 1/1/04.]



296-842-12005
Develop and maintain a written program.

Exemption:
This section does not apply to respirator use that is voluntary. See WAC 296-842-11005 for voluntary use program requirements.
(1) Develop a complete worksite-specific written respiratory protection program that includes the applicable elements listed in Table 3. The program shall cover each employee required by this section to use a respirator.
Note:
Pay for respirators, medical evaluations, fit testing, training, maintenance, travel costs, and wages.
(2) Keep your program current and effective by evaluating it and making corrections. Do ALL of the following:
(a) Make sure procedures and program specifications are followed and appropriate.
(b) Make sure selected respirators continue to be effective in protecting employees. For example, if changes in work area conditions, level of employee exposure, or employee physical stress have occurred, you need to reevaluate your respirator selection.
(c) Have supervisors periodically monitor employee respirator use to make sure employees are using them properly.
(d) Regularly ask employees required to use respirators about their views concerning program effectiveness and whether they have problems with:
– Respirator fit during use
– Any effects of respirator use on work performance
– Respirators being appropriate for the hazards encountered
– Proper use under current worksite conditions
– Proper maintenance.

296-842-13005
Select and provide appropriate respirators.

Exemption:
This section does NOT apply to respirator use that is voluntary. See WAC 296-842-11005 for voluntary use program requirements.
IMPORTANT:
See chapter 296-841 WAC, Airborne contaminants, for:
• Hazard evaluation requirements. Evaluation results are necessary for respirator selection.
• References to substance-specific rules that may also apply to you and have additional respirator selection requirements. These references are found in the permissible exposure limit (PEL) table.
A respirator shall be provided to each employee when such equipment is necessary to protect the health of the employee. Select and provide, at no cost to employees, appropriate respirators for routine use, infrequent use, and reasonably foreseeable emergencies (such as escape, emergency, and spill response situations) by completing the following process:
Respirator Selection Process
Step 1: If your only respirator use is for escape, skip to Step 8 to select appropriate respirators.
Step 2: If the respiratory hazard is a biological aerosol, such as TB (tuberculosis), anthrax, psittacosis (parrot fever), or hanta virus, select a respirator appropriate for nonemergency activities recognized to present a health risk to workers AND skip to Step 8.
• If respirator use will occur during emergencies, skip to Step 8 and document the analysis used to select the appropriate respirator.
• Use Centers for Disease Control (CDC) selection guidance for exposures to specific biological agents when this guidance exists. Visit http://www.cdc.gov.
Step 3: If the respiratory hazard is a pesticide, follow the respirator specification on the pesticide label AND skip to Step 9.
Step 4: Determine the expected exposure concentration for each respiratory hazard of concern. Use the results from the evaluation required by chapter 296-841 WAC, Airborne contaminants.
Step 5: Determine if the respiratory hazard is classified as IDLH; if it is NOT IDLH skip to Step 7.
• The respiratory hazard is classified as IDLH if:
– The atmosphere is oxygen deficient or oxygen enriched;
or
– You CANNOT measure or estimate your expected exposure concentration;
or
– Your measured or estimated expected exposure concentration is greater or equal to the IDLH value in the NIOSH Pocket Guide to Chemical Hazards.
Note:
DOSH uses the IDLH values in the 1990 edition of the NIOSH Pocket Guide to Hazardous Chemicals to determine the existence of IDLH conditions. You may use more recent editions of this guide. Visit www.cdc.gov/niosh for more information.
Step 6: Select an appropriate respirator from one of the following respirators for IDLH conditions and skip to Step 8:
• Full-facepiece, pressure demand, self-contained breathing apparatus (SCBA) certified by NIOSH for a minimum service life of thirty minutes;
OR
• Full-facepiece, pressure demand air-line respirator equipped with an auxiliary self-contained air supply.
Exception:
If the respiratory hazard is oxygen deficiency AND you can show oxygen concentrations can be controlled within the ranges listed in Table 4 under ALL foreseeable conditions, you are allowed to select any type of SCBA or air-line respirator:
Table 4
Concentration Ranges for Oxygen Deficiency
Altitude
(as ft. above sea level)
Oxygen Concentration Range
(as percent oxygen)
Below 3,001
16.0 - 19.5
3,001 - 4,000
16.4 - 19.5
4,001 - 5,000
17.1 - 19.5
5,001 - 6,000
17.8 - 19.5
6,001 - 7,000
18.5 - 19.5
7,001 - 8,000
19.3 - 19.5
Above 8,000 feet the exception does not apply. Oxygen-enriched breathing air must be supplied above 14,000 feet.
Step 7: Select respirator types with assigned protection factors (APFs) from Table 5 that are appropriate to protect employees from the expected exposure concentration.
Note:
• Appendix B, using assigned protection factors (APFs) for respirator selection, found in this chapter, uses the hazard-ratio approach established by ANSI Z88.2-1992 to determine which respirator types can provide a sufficient level of protection.
 
• If no permissible exposure limit (PEL) is established for an airborne contaminant, use relevant available information and informed professional judgment to determine an acceptable exposure limit value to use for calculating hazard ratios. For example, you may use exposure limit values established by the American Conference of Governmental Industrial Hygienists (ACGIH).
Step 8: Consider hazards that could require selection of specific respirator types. For example, select full-facepiece respirators to prevent eye irritation or abrasive blasting helmets to provide particle rebound protection.
Note:
Rules for specific substances have additional selection specifications that apply to escape and other types of respirators. Make sure you follow those additional requirements before finalizing your selection.
Step 9: Evaluate user and workplace factors that might compromise respirator performance, reliability or safety.
Examples:
• High humidity or temperature extremes in the workplace.
• Necessary voice communication.
• High traffic areas and moving machinery.
• If respirator use is for escape only, follow this step and then skip to Step 11.
• If the respiratory hazard is a pesticide, follow the requirements on the pesticide label and skip to Step 11.
• Time or distance for escape.
Step 10: Follow Table 6 requirements to select an air-purifying respirator.
• If Table 6 requirements cannot be met, you must select an appropriate air-line respirator or an SCBA.
Step 11: Make sure respirators you select are certified by the National Institute for Occupational Safety and Health (NIOSH).
• Respirators provided exclusively for escape from IDLH atmospheres must be NIOSH-certified for escape from the atmosphere in which they will be used.
• To maintain certification, make sure the respirator is used according to cautions and limitations specified on the NIOSH approval label. This includes manufacturer restrictions on cartridges and canisters.
For SCBAs, use only the respirator manufacturer's NIOSH-approved breathing gas containers, marked and maintained in accordance with the Quality Assurance 68 provisions of the NIOSH approval for the SCBA as issued in accordance with the NIOSH respirator certification standard at 42 C.F.R. Part 84.
Note:
While selecting respirators, you will need to select a sufficient number of types, models or sizes to provide for fit testing. You can also consider other respirator use issues, such as accommodating facial hair with a loose fitting respirator.
Use Table 5 to identify the assigned protection factor for different types of respirators.
• These assigned protection factors are only effective when the employer implements a continuing, effective respirator program as required by this chapter, including training, fit testing, maintenance, and use requirements.
• You may select respirators assigned for use in higher workplace concentrations of a hazardous substance for use at lower concentrations of that substance, or when required use is independent of concentration.

296-842-14005
Provide medical evaluations.

Exemption:
This section does not apply to employees who only use:
 
• Filtering-facepiece respirators voluntarily. See WAC 296-842-11005 for voluntary use requirements; or
 
• Escape-only respirators that are mouthpiece, loose-fitting, or hooded respirators.
important:
• If an employee has been provided with a medical evaluation addressing respirator use, as required by another chapter, that evaluation will meet the requirements of this section.
• Using a respirator can create physical risks for an employee each time it is worn. The extent of these risks depends on these factors:
– Type of respirator;
– Environmental conditions at the worksite;
– Physical demands of the work;
– Use of the protective clothing;
– Employee's health status.
Follow the medical evaluation process, Steps 1 through 7 in this section, to provide medical evaluations for employees at no cost to them.
Medical Evaluation Process
Step 1: Identify employees who need medical evaluations AND determine the frequency of evaluations from Table 7. Include employees who:
• Are required to use respirators;
or
• Voluntarily use respirators that are not filtering-facepiece respirators.
Note:
You may use a previous employer's medical evaluation for an employee if you can:
 
• Show the employee's previous work and use conditions were substantially similar to yours;
 
and
 
• Obtain a copy of the licensed health care professional's (LHCP's) written recommendation approving the employee's use of the respirator chosen by you.
Step 2: Identify a licensed health care professional (LHCP) to perform your medical evaluations.
Note:
If you select a different LHCP, you do not need to have new medical evaluations done.
Step 3: Make sure your LHCP has the following information before the evaluation is completed:
• Information describing the respirators employees may use, including the weight and type.
• How the respirators will be used, including:
– How often the respirator will be used, for example, daily, or once a month;
– The duration of respirator use, for example, a minimum of one hour, or up to twelve hours;
– The employee's expected physical work effort;
– Additional personal protective clothing and equipment to be worn;
– Temperature and humidity extremes expected during use;
• A copy of your written respiratory protection program and this chapter.
Note:
• You may choose to send the questionnaire to the LHCP ahead of time, giving time to review it and add any necessary questions.
 
• The LHCP determines what questions to add to the questionnaire, if any; however, questions in Parts 1-3 may not be deleted or substantially altered.
Step 4: Administer the medical questionnaire in WAC 296-842-22005 to employees, OR provide them a medical exam that obtains the same information.
Note:
You may use online questionnaires if the questions are the same and requirements of this section are met.
• Administer the examination or questionnaire at no cost to employees:
– During the employee's normal working hours;
or
– At a time and place convenient to the employee.
• Maintain employee confidentiality during examination or questionnaire administration:
– Do not view employee's answers on the questionnaire;
– Do not act in a manner that may be considered a breach of confidentiality.
Note:
Providing confidentiality is important for securing successful medical evaluations. It helps make sure the LHCP gets complete and dependable answers on the questionnaire.
• Make sure employees understand the content of the questionnaire.
• Provide the employee with an opportunity to discuss the questionnaire or exam results with the LHCP.
Step 5: Provide follow-up evaluation for employees when:
• The LHCP needs more information to make a final recommendation;
or
• An employee gives any positive response to questions 1-8 in Part 2 OR to questions 1-6 in Part 3 of the DOSH medical evaluation questionnaire in WAC 296-842-22005.
Note:
Follow-up may include:
 
• Employee consultation with the LHCP such as a telephone conversation to evaluate positive questionnaire responses;
 
• Medical exams;
 
• Medical tests or other diagnostic procedures.
Step 6: Obtain a written recommendation from the LHCP that contains only the following medical information:
• Whether or not the employee is medically able to use the respirator;
• Any limitations of respirator use for the employee;
• What future medical evaluations, if any, are needed;
• A statement that the employee has been provided a copy of the written recommendation.
Step 7: Provide a powered, air-purifying respirator (PAPR) when the LHCP determines the employee should not wear a negative-pressure air-purifying respirator AND is able to wear a PAPR.
Reference:
See WAC 296-842-13005 for requirements regarding selection of air-purifying respirators.
Note:
• You may discontinue medical evaluations for an employee when the employee no longer uses a respirator.
 
• If you have staff conducting your medical evaluations, they may keep completed questionnaires and findings as confidential medical records, if they are maintained separately from other records.
Use Table 7 to determine medical evaluation frequency.
Table 7
Evaluation Frequency
Type of Evaluation:
When required:
Initial medical evaluations
• Before respirators are fit-tested or used in the workplace.
Subsequent medical evaluations
• If any of these occur:
 
 
– Your licensed health care professional (LHCP) recommends them; for example, periodic evaluations at specified intervals.
 
 
– A respirator program administrator or supervisor informs you that an employee needs reevaluation.
 
 
– Medical signs or symptoms (such as breathing difficulties) are:
 
 
 
■ Observed during fit testing or program evaluation
 
 
 
or
 
 
 
■ Reported by the employee
 
 
– Changes in worksite conditions such as physical work effort, personal protective clothing, or temperature that could substantially increase the employee's physiological stress.

296-842-15005
Conduct fit testing.

Exemption:
This section does not apply to any respirators that are:
 
• Voluntarily used. See WAC 296-842-11005 for voluntary use requirements.
 
• Mouthpiece respirators and other escape-only respirators.
 
• Loose-fitting respirators.
IMPORTANT:
• Fit testing is an activity where the seal of a respirator is tested to determine if it's adequate.
(1) Provide, at no cost to the employee, fit tests for ALL tight fitting respirators on the following schedule:
(a) Before employees are assigned duties that may require the use of respirators;
(b) At least every twelve months after initial testing;
(c) Whenever any of the following occurs:
■ A different respirator facepiece is chosen such as a different type, model, style, or size;
■ You become aware of a physical change in an employee that could affect respirator fit. For example, you may observe, or be told about, facial scarring, dental changes, cosmetic surgery, or obvious weight changes;
■ An employee notifies you, or your LHCP, that the respirator fit is unacceptable. During the retest, you must give an employee reasonable opportunity to select a different respirator facepiece (size, model, etc.).
Note:
You may accept a fit test completed by a previous employer IF:
 
• You obtain written documentation of the fit test;
 
AND
 
• The results of the fit test are not more than twelve months old;
 
AND
 
• The employee will use the same respirator (the same type, model, style, and size);
 
AND
 
• The fit test was conducted in a way that meets the requirements of WAC 296-842-15005 and 296-842-22010.
(2) Select and use an appropriate fit-testing procedure from WAC 296-842-22010 of this chapter.
(3) Use quantitative fit-test methods when a negative pressure respirator will be used in concentrations requiring a protection factor greater than 10. This includes:
■ Full facepiece air-purifying respirators;
■ SCBAs operated in demand (negative pressure) mode;
■ Air-line respirators operated in demand mode.
(4) Make sure tight-fitting PAPRs, SCBAs, or air-line respirators are fit tested in negative-pressure mode. This must be done by either:
(a) Temporarily converting the respirator user's actual facepiece into a negative pressure respirator using the appropriate filters;
OR
(b) Using an identical negative pressure air-purifying respirator facepiece as a surrogate for the SCBA, air-line or PAPR. The surrogate facepiece must have the same sealing surfaces as the SCBA, air-line, or PAPR.
Remove any modifications made to the respirator facepiece for fit testing and return the facepiece to the NIOSH approved configuration before the facepiece is used in the workplace.
(5) Make sure the person conducting fit testing is able to do ALL of the following:
(a) Prepare test solutions if required;
(b) Make sure equipment works properly;
(c) Perform tests properly;
(d) Recognize invalid tests;
(e) Calculate fit factors properly if required.
Note:
• No specific training program or certification is required for those who conduct fit tests.
 
• You should consider evaluating these individuals to determine their proficiency in the fit-testing method to be used.
 
• You can use an evaluation form such as the form included in the American National Standard for Respirator Fit Testing Methods, ANSI/AIHA Z88.10-2001 to determine if the individual meets these requirements. Visit www.ansi.org or www.aiha.org.

(c) Additionally, when the following occur:
■ The employee has not retained knowledge or skills
OR
■ Changes in the worksite, or type of respirator make previous training incomplete or obsolete.
Note:
• You may accept an employee's previous training, such as training provided by another employer, to satisfy the initial training requirement if:
 
– You can demonstrate the employee received training within the past twelve months
 
AND
 
– The employee can demonstrate the knowledge and skills to use required respirators effectively.
 
• If you accept an employee's previous training to satisfy the initial training requirement, you are still responsible for providing periodic, and additional training when needed. Periodic training would need to be provided within twelve months of the employee's previous training.
(5) Make sure employees can demonstrate the following knowledge and skills as required by their duties:
(a) Why the respirator is necessary. Include, for example, information identifying respiratory hazards such as hazardous chemicals, the extent of the employee's exposure, and potential health effects and symptoms
(b) The respirator's capabilities and limitations. Include, for example, how the respirator provides protection and why air-purifying respirators cannot be used in oxygen-deficient conditions
(c) How improper fit, use, or maintenance can compromise the respirator's effectiveness and reliability

Provide standby assistance in immediately dangerous to life or health (IDLH) conditions.

IMPORTANT:
DOSH currently uses the IDLH values in the 1990 NIOSH Pocket Guide to Chemical Hazards to determine the existence of IDLH conditions. You may use more recent editions of this guide. Visit www.cdc.gov/niosh for more information.
(1) Provide at least two standby employees outside the IDLH area.
Note:
You need only one standby employee if the IDLH condition is well characterized, will remain stable and you can show one employee can adequately do all of the following:
 
• Monitor employees in the IDLH area;
 
• Implement communication; and
 
• Initiate rescue duties.
(2) Train and equip standby employees to provide effective emergency rescue. Equip them with:
(a) A pressure-demand SCBA or a pressure-demand air-line respirator with an auxiliary SCBA, for each standby employee;
(b) Appropriate retrieval equipment, when it would help with the effective rescue of the entrant, or an equivalent means of rescue.
(3) Make sure standby employees maintain visual, voice, or signal line communication with employees in the IDLH area.
(4) Make sure that in the event of an emergency:
(a) Standby employees notify you or your designee before they enter the IDLH area to provide emergency rescue;
(b) You provide necessary assistance when notified.

296-842-20010
Prevent conditions that could create a hazardous breathing air supply.

(1) Use SCBA and air-line respirators safely:
DO NOT supply compressed oxygen to SCBAs or air-line respirators that previously used compressed air.
Note:
Compressed air leaves residues containing hydrocarbons such as oil or grease. Fire or explosion can occur if compressed oxygen makes contact with these residues.
(2) Use breathing air couplings on air-line respirators that are NOT compatible with couplings for nonrespirable air or other gas systems, for example, utility air used for manufacturing purposes.
(3) DO NOT allow asphyxiating substances to enter breathing air lines; for example, do not flush nitrogen through worksite air lines also used for breathing air.
(4) Use equipment specifically designed for oxygen service or distribution IF oxygen concentrations greater than 23.5% are used.
Note:
Respiratory equipment NOT designed for oxygen service or distribution can create fire or explosion hazards in oxygen concentrations higher than 23.5%.
(5) Make sure cylinders used to supply breathing air for SCBAs or air-line respirators are tested and maintained as described in the federal Department of Transportation's (DOT) Shipping Container Specification Regulations, Title 49 C.F.R. Part 180.
Note:
• Use only cylinders marked (with serial number, cylinder pressure, DOT exemption number, and test dates) according to these DOT regulations
 
• To find any Code of Federal Regulations (C.F.R.) visit: www.access.gpo.gov.

296-842-20015
Make sure compressors do not create a hazardous breathing air supply.

IMPORTANT:
• Ambient-air movers (or pumps) used to supply air to respirators must be used according to the manufacturer's instructions.
• Respirators used with ambient-air movers must be approved by NIOSH to operate within the pressure ranges of the air mover.
(1) Locate or modify compressor intakes so they will not pick up contaminated air OR exhaust gases such as carbon monoxide (CO) from:
• Fuel-powered vehicles
OR
• The internal combustion motor of the compressor
OR
• Other contaminant sources in the area, for example, a ventilation system discharge.
Note:
• You may need to reposition or extend the compressor's intake or engine exhaust pipe or outlet, especially if they are located near each other.
 
• Be aware that exhaust gases may not adequately disperse when the compressor is operated in:
 
– An enclosed space such as a small room, a corner, or near a wall
 
OR
 
– In turbulent wind conditions.
(2) Equip compressors with suitable air-purifying filters, water traps, and sorbents (such as charcoal beds) and maintain them as follows:
(a) Periodically change or clean them according to the manufacturer or supplier's instructions
(b) Keep a tag at the compressor with the following information:
– When the sorbent and filters were last replaced or cleaned
– The date of the most recent changes or cleaning
– The signature of the person authorized by the employer to perform changes or cleaning.
Note:
To be sure you are providing the recommended operating pressure for respirators, you may need to install a delivery pressure gauge where the respirator's airline hose attaches to the manifold or other air outlet.
(3) Make sure the carbon monoxide (CO) level in breathing air from compressors does not exceed ten parts per million (ppm).
Maintain CO levels below ten ppm in oil lubricated compressors by using at least one of the following:
(a) An effective CO alarm
(b) An effective high temperature alarm and testing the air supply often enough to prevent CO levels from exceeding ten ppm.
Note:
• If you do not have a reliable CO-free area available for locating your compressor intake, consider these examples of methods to prevent CO contamination of the air supply:
 
– Use of continuous and effective carbon monoxide alarms and filters
 
– Conduct frequent monitoring of air quality
 
– Use a CO converter (converts CO to carbon dioxide).
 
• How often to test depends on a number of considerations, for example:
 
– Compressor age
 
– Maintenance history of the compressor
 
– Stability of CO readings
 
• If the CO or high temperature alarm cannot be heard by the employee, a flashing light or other effective alternative to an audio alarm needs to be used
 
• Safeguards, such as alarms, are necessary to prevent CO contamination resulting from compressor overheating. When alarms are provided, proper maintenance practices such as periodic inspections and calibration will help make sure alarms remain effective
 
• Any type of oil-lubricated compressor, such as screw or piston types, may produce dangerous levels of CO if overheating occurs
 
– Old compressors are known to leak oil due to worn parts, increasing the possibility for overheating. Newer compressors may also overheat if maintenance practices are poor. For example, poor maintenance practices may lead to disconnected or incorrectly set alarms, inoperative shut-offs, or an impaired cooling system
 
• You need to instruct employees to move to a safe area when the alarm sounds AND to stop using respirators.

296-842-22010
Follow these fit-testing procedures for tight-fitting respirators.

important:
• This section contains procedural requirements that apply during actual fit testing.
• See WAC 296-842-15005 of this chapter for fit-testing requirements that apply to your overall program.
Exemptions:
This section does not apply to employees who:
 
Voluntarily use respirators;
 
or
 
Are required to use mouthpiece respirators.
(1) Follow the procedure in Table 11 to choose a respirator for fit testing:
(a) Prior to conducting fit tests;
and
(b) Any time your employee must select a different respirator such as when a previously selected respirator fails a test.
(2) Select and follow at least one of the following fit test procedures:
(a) Qualitative fit-test procedures:
♦ Isoamyl acetate vapor (IAA, banana oil) in Table 12;
♦ Saccharine aerosol in Table 13;
♦ Bitrex™ aerosol in Table 14;
♦ Irritant smoke in Table 15.
(b) Quantitative fit-test procedures:
♦ Ambient aerosol condensation nuclei counter such as the Portacount™, in Table 16;
♦ Controlled negative pressure (CNP) such as the FitTester 3000™, in Table 17;
♦ Generated aerosol in Table 18.
(3) Make sure employees perform the appropriate fit-test exercises listed in Table 19.
(4) Clean and maintain equipment according to the manufacturer's instructions.
(5) Make sure during fit testing employees wear any safety equipment that could:
(a) Interfere with respirator fit;
and
(b) Be worn in the workplace. For example, chemical splash goggles.
(6) Check, prior to fit testing, for conditions that may interfere with the respirator seal or valve functions. If you find such conditions, do not conduct fit testing for that individual.
Note:
Examples of conditions that may interfere with the respirator seal or valve functions include:
 
Moustache, stubble, sideburns, bangs, hairline, and other types of facial hair in areas where the respirator facepiece seals or that interfere with valve function.
 
Temple bars of corrective eyewear or headgear that extend through the face seal area.
(7) Follow the appropriate fit test exercises in Table 19 as indicated.
Table 11
Procedure for Choosing a Respirator for Fit Testing
1. Inform the employee:
 
• To choose the most comfortable respirator that provides an adequate fit
 
• That each respirator sample represents a different size and, if more than one model is supplied, a different shape
 
• That if fitted and used properly, the respirator chosen will provide adequate protection
2. Provide a mirror and show the employee how to:
 
• Put on the respirator
 
• Position the respirator on the face
 
• Set strap tension.
Note:
This instruction does NOT take the place of the employee's formal training since it is only a review.
3. Review with the employee how to check for a comfortable fit around the nose, cheeks and other areas on the face.
 
• Tell the employee the respirator should be comfortable while talking or wearing eye protection.
4. Have the employee hold each facepiece against the face, taking enough time to compare the fit of each. The employee can then either:
 
• Reject any facepiece that clearly does not feel comfortable or fit adequately
 
or
 
• Choose which facepiece is most acceptable and which are less acceptable, if any.
Note:
• Supply as many respirator models and sizes as needed to make sure the employee finds a respirator that is acceptable and fits correctly
• To save time later, during this step note the more acceptable facepieces in case the one chosen fails the fit test or proves unacceptable later.
5. Have the employee wear the most acceptable respirator for at least 5 minutes to evaluate comfort and fit. Do all of the following during this time:
 
• Ask the employee to observe and comment about the comfort and fit:
 
 
– Around the nose, cheeks, and other areas on the face
 
 
– When talking or wearing eye protection
 
• Have the employee put on the respirator and adjust the straps until they show proficiency
 
• Evaluate the respirator's general fit by checking:
 
 
– Proper chin placement
 
 
– Properly tightened straps (do not over tighten)
 
 
– Acceptable fit across the nose bridge
 
 
– Respirator size; it must span the distance from nose to chin
 
 
– To see if the respirator stays in position
 
• Have the employee complete a successful seal check as specified in WAC 296-842-22020 of this chapter
 
 
– Prior to the seal check they must settle the respirator on their face by taking a few slow deep breaths WHILE SLOWLY:
 
 
 
■ Moving their head from side-to-side
 
 
 
AND
 
 
 
■ Up and down.
6. If the employee finds the respirator unacceptable, allow the employee to select another one and return to Step 5. Otherwise, proceed to Step 7.
7. Before starting the fit test, you must:
 
• Describe the fit test including screening procedures, employee responsibilities, and test exercises
 
and
 
• Make sure the employee wears the respirator at least five minutes.
Table 12
Isoamyl Acetate (Banana Oil) Vapor Test Procedure
Important:
 
• This is a qualitative fit-test (QLFT) procedure
 
• The success of this test depends on preserving the employee's odor sensitivity to isoamyl acetate (IAA) vapor
 
 
– Vapor accumulations in ambient air can decrease odor sensitivity. To prevent this:
 
 
 
■ Prepare all solutions in a location separate from screening and test areas
 
 
 
■ Conduct screening and tests in separate well-ventilated rooms. For example, use an exhaust fan or laboratory hood to prevent IAA vapor from accumulating in the room air
 
 
– Always use odor-free water, for example, distilled or spring water that is 25°C (77°F).
 
• Isoamyl acetate is also known as isopentyl acetate.
Screening Preparations
Important:
 
Odor threshold screening determines if the employee can detect weak concentrations of IAA vapor.
1. Choose an appropriate location to conduct screening.
 
• Conduct screening and tests in separate well-ventilated rooms.
2. Prepare a stock solution AT LEAST weekly as follows:
 
• Add one milliliter (ml) of pure IAA to 800 ml of odor-free water in a one-liter glass jar with a metal lid using a measuring dropper or pipette
 
• Seal the jar with the lid and shake it for 30 seconds
 
• Clean the dropper or pipette.
3. Prepare the odor test solution daily as follows:
 
• Add 0.4 ml from the stock solution to 500 ml of water in a one liter glass jar with a metal lid using a clean pipette or dropper
 
• Seal the jar with the lid and shake it for 30 seconds
 
• Let this solution stand for 2-3 minutes so the IAA concentration above the liquid reaches equilibrium
 
• Label this jar so you know the contents but the employee cannot know its contents, for example, "1."
Note:
To maintain the integrity of the test, use labels that peel off easily and periodically switch the labels.
4. Prepare a "test blank" solution as follows:
 
• Add 500 ml of odor-free water to a one liter glass jar with a metal lid
 
• Seal the jar
 
• Label the jar so you know the contents but the employee cannot know its contents.
5. Type or neatly print the following instructions on a card and place it on the table in front of the two test jars:
 
"The purpose of this test is to find out if you can smell banana oil at a low concentration. While both jars contain water, one ALSO contains a small amount of banana oil.
 
Make sure the lid is secure then pick up a jar and shake it for two seconds. Open the jar and sniff at the opening. Repeat this for the second jar.
 
Tell the individual conducting the fit test which jar contains banana oil."
Test Preparations
6. Choose an appropriate location to conduct fit testing.
 
• Conduct screening and tests in separate well-ventilated rooms.
7. Assemble the fit test enclosure in the room.
 
• Invert a clear 55-gallon drum liner over a circular 2-foot diameter frame made of plywood or other lightweight rigid material OR construct a similar enclosure using plastic sheeting
 
• Hang the frame with the plastic covering so the top of the enclosure is about six inches above the employee's head
 
• Attach a small hook inside top center of the enclosure
 
• Tape a copy of the test exercises (see Table 19) to the inside of the test enclosure where the employee can read it.
8. Have organic vapor cartridges or equivalent on hand for each employee's chosen respirator.
9. Have ready a 6 x 5-inch piece of paper towel or other porous absorbent single-ply material and 0.75 ml of pure IAA. Do NOT apply IAA yet.
Note:
As an alternative to using the paper towel, you may use an IAA test swab OR ampoule if it has been demonstrated to generate an equivalent test concentration.
Screening
10. Have the employee, while not wearing a respirator, follow the instructions on the card provided.
 
• If the employee correctly identifies the jar containing IAA, proceed to conduct testing (Step 11)
 
• If the employee is not able to correctly identify the jar containing IAA, you must stop and use a different fit test protocol.
Test
11. before entering the fit test room, have the employee attach cartridges, put on, properly adjust, and seal check the respirator. Have the employee enter the test enclosure.
12. Wet the paper towel with 0.75 ml of pure IAA and fold it in half.
13. Pass the paper towel to the employee inside the enclosure and instruct the employee to hang it on the hook at the top of the enclosure.
14. Wait two minutes for the IAA vapor to fill the enclosure.
 
• While waiting, explain the fit test, including the purpose of the test exercises, the importance of cooperation, and that you must be informed if a banana-like odor is detected during the test
 
• You may also demonstrate the test exercises.
15. Have the employee perform the appropriate fit-test exercises in Table 19.
 
• If the employee does NOT detect IAA while performing test exercises, the fit test has been passed. Proceed as follows:
 
 
BEFORE leaving the enclosure, have the employee break the respirator seal and inhale. If they detect IAA, the test is valid
 
 
– When exiting the employee must remove the paper towel and give it to the individual conducting the fit test. This prevents IAA vapor from building up in the enclosure during subsequent tests
 
 
– The individual conducting the fit test must keep used paper towels in a self-sealing plastic bag to prevent area contamination
 
• If the employee detects IAA during any test exercise, the fit test has FAILED. STOP and have the employee do the following:
 
 
– Quickly return to the selection room to remove the respirator. This avoids decreasing the employee's odor sensitivity
 
 
– Select another respirator
 
 
– Repeat screening and testing
 
 
 
■ At this stage, if the employee fails the screening part of this procedure, the employee can repeat it after waiting at least five minutes for odor sensitivity to return.
Table 13
Saccharin Aerosol Test Procedure
Screening Preparations
Important:
 
• This is a qualitative fit-test (QLFT) procedure
 
• Taste threshold screening determines whether the employee being tested can detect the taste of saccharin
 
 
– The employee must NOT eat, smoke, chew gum or drink anything but plain water for at least fifteen minutes BEFORE the fit test. Sweet foods or drink consumed before the test may make the employee unable to detect saccharin during screening
 
 
– Nebulizers must be thoroughly rinsed in water and shaken dry:
 
 
 
■ Each morning and afternoon
 
 
 
or
 
 
 
■ At least every four hours.
 
• You may use commercially prepared solutions if they meet the requirements in this procedure.
1. Obtain a test enclosure (hood) that meets the following specifications:
 
• Twelve inches in diameter by fourteen inches tall
 
• A clear front portion
 
• Enough space inside to allow free movement of the head when a respirator is worn
 
• A 3/4 inch (or 1.9 centimeter) hole to accommodate the nebulizer nozzle. The hole must line up in front of the wearer's nose and mouth.
Note:
• An enclosure similar to the 3M hood assembly, parts #FT 14 and #FT 15 combined, meets these specifications
• This enclosure can also be used for testing.
2. Obtain and assemble two clean DeVilbiss Model 40 Inhalation Medication Nebulizers OR equivalent.
3. Prepare the screening solution as follows:
 
• Dissolve 830.0 milligrams of sodium saccharin USP in 100 ml of warm distilled water
 
or
 
if you have already prepared the fit-test solution, you can make the screening solution by adding 1 ml of this solution to 100 ml of distilled water.
4. Add about 1 ml of the screening solution to one of the nebulizers.
 
• Mark this nebulizer to distinguish it from the one to be used for fit testing.
Test Preparations
5. Prepare the fit-test solution as follows:
 
• Add 83.0 grams of sodium saccharin to 100 ml of warm water.
6. Add about 1 ml of the test solution to the second nebulizer.

8. Have the employee, while NOT wearing a respirator, put on the test enclosure.
9. Instruct the employee to:
 
• Breath through a slightly open mouth with tongue extended during screening and testing
 
• Immediately report when a sweet taste is detected.
10. Insert the nebulizer into the front hole of the test enclosure and administer saccharin as follows:
 
• Direct the nozzle away from the employee's nose and mouth
 
• Complete 10 squeezes in rapid succession
 
• Each time firmly squeeze the bulb so it collapses completely, then release and allow it to fully expand.
11. Ask the employee if a sweet taste is detected.
 
• If yes, screening is completed. Proceed to conduct testing, Step 14, after you:
 
 
– Ask the employee to remember the taste for reference during the fit test
 
 
– Note the employee's taste threshold as "10" regardless of the number of squeezes actually completed
 
• If no, screening must continue. Proceed to Step 12.
12. Repeat with 10 more squeezes. Then follow Step 11 again; except this time note the employee's taste threshold as "20" if a sweet taste is reported.
 
• If a sweet taste is still not detected, repeat with 10 more squeezes and follow Step 11 one last time; EXCEPT this time note "30" for the taste threshold IF a sweet taste is reported.
13. If no sweet taste is reported after 30 squeezes, you must stop and choose a different fit-test protocol for the employee.
Test
 
Important!
 
• Periodically check nebulizers to make sure they do not clog during use. A test is NOT valid if the nebulizer is clogged at the end of the test.
14. Have the employee attach particulate filters, put on, properly adjust, and seal check the respirator. Have the employee put on the test enclosure (hood).
15. Instruct the employee to immediately report if a sweet taste is detected.

Table 15
Irritant Smoke (Stannic Chloride) Test Procedure
 
Important:
 
DO NOT USE A TEST ENCLOSURE OR HOOD FOR THIS FIT TEST!
 
• This is a qualitative fit-test (QLFT) procedure
 
• During this test an employee is exposed to irritating smoke containing hydrochloric acid produced by a stannic chloride ventilation smoke tube to detect leakage. The smoke will irritate eyes, lungs, and nasal passages
 
• Employee sensitivity varies, and certain employees may respond more intensely than others exposed to irritant smoke. The individual conducting the fit test must take precautions to minimize the employees' exposure to irritant smoke
 
• Conduct fit testing in an area with adequate ventilation to prevent exposure of the individual conducting the fit test and build-up of irritant smoke in the ambient air.
Screening AND Test Preparations
 
Important:
 
Sensitivity screening is necessary to determine whether the employee can detect a weak concentration of irritant smoke AND whether any gross facepiece leakage is detected.
1. Obtain only stannic chloride (ventilation) smoke tubes, and an aspirator squeeze bulb or use a low-flow air pump set to deliver 200 milliliters of air flow per minute.
2. Equip the employee's chosen respirator with P100 series filters if a negative pressure air-purifying respirator will be tested. If a powered air-purifying respirator (PAPR) will be tested equip the respirator with high-efficiency particulate air (HEPA) filters.
Screening
 
Important!
 
When performing sensitivity screening checks use only the MINIMUM amount of smoke necessary to elicit a response from the employee.
3. Advise the employee that the smoke can be irritating to eyes, lungs, and nasal passages and instruct the employee to keep eyes closed while exposed.
4. Break both ends of the ventilation smoke tube and fit a short piece of plastic tubing, for example, two-to-six inches of tygon tubing, over one end to prevent exposure to the sharp end of the tube. Connect the other end to an aspirator bulb or a low-flow air pump set to deliver a flow of 200 ml per minute.
5. While the employee is not wearing a respirator, have the employee smell a weak concentration of irritant smoke to become familiar with its irritating properties.
 
• Carefully direct a small amount of irritant smoke toward the employee.
Test
Test 6. Have the employee attach respirator filters, put on, adjust, and seal check the respirator without assistance. The employee must be proficient at these tasks.
7. Remind the employee to keep eyes closed during testing.
8. Direct a stream of irritant smoke toward the respirator's face seal area as follows:
 
• Begin at least 12 inches from the facepiece and move the smoke around the whole perimeter of the mask
 
• Gradually make two more passes around the perimeter of the facepiece, moving to within 6 inches of the respirator
 
stop at any time the employee detects smoke in the facepiece. If this occurs a different respirator will need to be chosen and tested, beginning with sensitivity screening.
9. Have the employee perform appropriate fit-test exercises in Table 19 if the employee has not had an involuntary response such as evidence of coughing, flinching, or other response, or detected smoke in the facepiece.
 
• Continue to direct smoke from a distance of 6 inches around the facepiece perimeter
 
 
– If smoke is detected at any time the test has FAILED. A different respirator must be chosen and tested, starting with sensitivity screening
 
 
– If no smoke is detected proceed to Step 10.
10. Have the employee remove the respirator and perform another sensitivity screening check as follows:
 
• Continue to use the smoke tube used for fit testing
 
• Carefully direct a SMALL amount of irritant smoke toward the employee
 
 
– The test has been PASSED IF the employee responds to the smoke
 
 
– The fit test is VOIDED IF the employee does not respond to the smoke.
Table 16
Ambient Aerosol Condensation Nuclei Counter
(Portacount™) Test Procedure
Important:
 
• This is a quantitative (QNFT) fit-test procedure
 
• This method uses a particle counting instrument that measures and compares the particle concentration both inside and outside the respirator facepiece while the employee performs a series of test exercises
 
• Particles in the ambient air are used as the test aerosol.
Test Preparations
1. Obtain a test instrument such as a Portacount™.
2. Have probed respirators available for each respirator model and size the employer uses, or have a sampling adapter available if the employee's actual or chosen respirator will be tested.
 
Note:
• A probed respirator has a special fitting installed on the facepiece designed to connect with the end of the test instrument's plastic sampling tube so that air samples can be taken inside the facepiece. Probed respirators can be obtained from the respirator manufacturer, or distributor, and can only be used for fit-testing purposes
• Contact TSI Inc., or the respirator's manufacturer to obtain probed respirators or facepiece sampling adapters.
3. Follow the test instrument manufacturer's instructions for test preparation, including particle, zero, and system checks. Make sure the instrument's pass or fail criterion is programmed to the following MINIMUM performance levels:
 
• For half-facepiece respirators, an overall minimum fit factor of 100 as a passing level
 
• For full-facepiece respirators, an overall minimum fit factor of 500 as a passing level
4. Have high-efficiency particulate air (HEPA) filters, OR other respirator filters available that are capable of preventing significant penetration by particles generated by the test instrument such as, P100 or N95 series filters.
 
• If you will use a sampling adapter instead of probed respirators be sure to have the correct type for the respirators chosen.
Test
5. Properly attach the sampling line to the facepiece probe or sampling adapter.
6. Have the employee attach respirator filters, put on, properly adjust, and wear the respirator five minutes before the fit test. During this time you and the employee must evaluate the respirator's general fit by checking:
 
• Proper chin placement
 
• Properly tightened straps (do not over tighten)
 
• Acceptable fit across the nose bridge
 
• Respirator size. It must span the distance from nose to chin
 
• To see if the respirator stays in position.
 
Note:
Wearing the respirator for five minutes permits the employee to make certain the respirator is comfortable and allows for purging of ambient particles trapped inside the facepiece.
7. Have the employee perform a seal check. Make sure the sampling line is crimped to avoid leakage during the seal check. If no leakage is detected, proceed to Step 8. If leakage is detected:
 
• Determine the cause
 
and
 
• If leakage is due to a poorly fitting facepiece, have the employee:
 
 
– Choose another respirator size or model
 
 
and
 
 
– Start again at Step 6.
8. Start the fit test cycle.
 
• Follow the manufacturer's instructions for operating the test instrument
 
• Have the employee perform the appropriate fit-test exercises in Table 19
 
 
– The test instrument will automatically stop and calculate the overall fit factor. Use this result to determine whether or not the test is passed
 
 
 
■ The test has been PASSED if the overall fit factor is at least 100 for a half facepiece, or 500 for a full facepiece
 
 
 
■ The test has FAILED if the overall fit factor is below 100 for a half facepiece or 500 for a full facepiece.
 
 
 
Note:
If the test has failed, have the employee select another respirator model or size following Table 11 and repeat this procedure.
Table 17
Controlled Negative Pressure (CNP) Test Procedure
Important!
 
• This is a quantitative fit-test (QNFT) procedure
 
• This method determines respirator fit by measuring how much the facepiece leaks when it is subject to a slight negative pressure AFTER various premeasurement activities
 
• Instruments used must have a nonadjustable test pressure of 15.0 mm water pressure
 
• Measurements occur while employees remain still and hold their breath for 10 seconds
 
• No test aerosols are used. Respirator cartridges are not needed for this test. Sampling manifolds that replace the filter cartridges are available from the instrument manufacturer, and allow fit testing of an employee's own respirator.
Test Preparations
1. Make sure the individual conducting the fit test is thoroughly trained to perform this test.
2. Obtain a CNP test instrument such as a FitTester 3000™. Make sure:
 
• Defaults are set at:
 
 
– -15mm (-0.58 inches) of water test pressure
 
 
and
 
– A modeled inspiratory flow rate of 53.8 liters per minute
 
• It has an effective audio warning device or visual screen tracing that signals when employees fail to hold their breath.
 
Note:
• You are not required to obtain test recording and printing equipment such as computers OR printers. Hand recording results is acceptable
• To see default settings, check the instrument's "REDON protocol."
3. Obtain facepiece adapters appropriate for each test respirator.
 
Note:
• Adapters are either a one-piece (for SCBA facepieces), OR two-piece (for dual cartridge facepieces) device providing a manifold and breathing valve system. For positive pressure respirators, you will need to obtain an additional fitting, available from the respirator manufacturer, to convert the facepiece to negative pressure
• To obtain adapters, contact the CNP instrument's distributor, Occupational Health Dynamics, or the respirator manufacturer.
Test
Important!
 
• The respirator must not be adjusted once the fit-test exercises begin. Any adjustment voids the test and the test must be repeated.
4. Explain the test procedure to the employee.
5. Train the employee on how to hold a breath for at least 10 seconds.
6. Prepare the respirator for the fit test as follows:
 
• Remove or prop open the inhalation valves. If a breathing tube is present, disconnect it
 
• Replace cartridges, if present, with the manifold and breathing valve adapter
 
 
– For positive pressure facepieces, mount the manufacturer's additional fitting followed by the manifold-breathing valve adapter
 
• Connect the respirator to the CNP device according to the CNP instrument manufacturer's directions.
7. Have the employee put on, adjust, and seal check the respirator without assistance.
8. Turn on the instrument and have the employee stand and perform the fit-test exercises in Table 19. Once exercises begin, any adjustments will void the test and you must begin again.
9. Once test exercises are completed, ask the employee about facepiece comfort. If the employee states the respirator is unacceptable, repeat the fit test using another size or model.
10. Determine the overall fit factor for each employee by calculating the harmonic mean of the fit-testing exercises as follows:
 
Overall fit factor =
n
 
 
 
 
1/ffE1 + 1/ffE2 + 1/ffE3 . . . + 1/ffEn
 
 
 
 
Where:
 
 
 
n = The number of exercises;
 
 
 
ffE1 = The fit factor for the first exercise;
 
 
 
ffE2 = The fit factor for the second exercise;
 
 
 
ffE3 = The fit factor for the third exercise; and
 
 
 
ffEn = The fit factor for the nth exercise.
 
• The test is PASSED IF the overall fit factor obtained is at least 100 for a half facepiece, or at least 500 for a full facepiece
 
• The test has FAILED IF the fit factor is less than 100 for a half facepiece; 500 for a full facepiece
 
 
– If the test has FAILED you must have the employee select another respirator model or size following the steps in Table 11 and repeat this procedure, starting at Step 6.
Table 18
Generated Aerosol Test Procedure
 
Important:
 
• This is a quantitative (QNFT) fit-test procedure
 
• In this method, a test aerosol is used to challenge the facepiece seal while aerosol concentrations inside and outside the facepiece are measured during test exercises
 
• Special equipment is needed to generate, disperse, detect, and measure test aerosols.
Test Preparations
1. Test aerosol.
 
• Use a particulate, for example, corn oil, polyethylene glycol 400, di-2-ethyl hexyl sebacate, or sodium chloride.
2. Instrumentation.
 
• Do all the following:
 
 
– Obtain and use aerosol generation, dilution, and measurement systems appropriate for particulates
 
 
– Use an aerosol-generating instrument that will maintain test concentrations within a 10% variation
 
 
– Select a sampling instrument that allows for a computer record or strip chart record to be created
 
 
 
■ The record must show the rise and fall of test agent concentration during each inhalation and exhalation at fit factors of at least 2000.
 
 
 
Note:
Integrators, or computers that integrate the amount of test agent penetration leakage into the respirator for each exercise, may be used if a record of the readings is made.
 
 
– Minimize the time interval between the activity and the recording of the activity so you can clearly connect what you see to what is being recorded. For example, use a small diameter and length of sampling line.
3. Test enclosure.
 
• Do all the following:
 
 
– Make sure the enclosure is equipped and constructed to effectively:
 
 
 
■ Maintain a uniform concentration of the test agent inside the enclosure. For example, the enclosure must be large enough to allow all employees freedom of movement during testing without disturbing the test concentration or measurement instrument
 
 
 
■ Keep the test agent from contaminating the air outside the enclosure. For example, use a HEPA filter to purify exhausted air
 
 
 
■ Allow the individual conducting the fit test to view the employee during the test
 
 
– Make sure the tubing used to collect samples from the enclosure and respirator is the same material, diameter, and length. This makes the effect of aerosol loss caused by deposition in each sample line equal
 
 
– If sodium chloride is used, relative humidity inside the enclosure must be kept below 50%.
4. Prepare test respirators.
 
• Do all the following:
 
 
– Inspect test respirators regularly for missing parts and damage
 
 
– Keep test respirators in proper working order
 
 
– Make sure in-mask sampling probes are:
 
 
 
■ Designed and installed so the air sample will be drawn from the employee's breathing zone; midway between the nose and mouth
 
 
 
and
 
 
 
■ The probe extends inside the facepiece at least 1/4 inch
 
 
– Make sure sampling ports such as probes, or adapters on respirators are constructed and installed so they do not:
 
 
 
■ Block air flow into the sampling line
 
 
 
■ Leak
 
 
 
■ Interfere with the respirator's fit or performance
 
• Have high efficiency particulate air (HEPA) filters or P100 series filter available
 
 
– Replace filters when increased breathing resistance is detected or when the test agent has altered the filter material's integrity.
Test
 
Important!
 
• Throughout the test, maintain the employee's exposure to any test agent below the established exposure limit. Exposures allowed must be based on exposure time and exposure limit duration
 
• If a single peak penetration exceeds 5% for half facepieces OR 1% for full facepieces:
 
 
STOP the test
 
 
and
 
 
– Have the employee select another respirator for testing.
5. Have the employee attach filters, put on, adjust, and seal check the respirator.
 
• Be sure to crimp the sampling line to avoid pressure leaks during the seal check
 
and
 
• Have the employee adjust the respirator straps, without assistance, so the fit is comfortable. Do not over tighten.
6. OPTIONAL Step. To save time conduct a screening test to quickly identify poorly fitting respirators.
 
Note:
You may use a qualitative screening test or an ambient aerosol condensation nuclei counter instrument in the count mode.
7. Make sure test aerosol concentration is reasonably stable.
 
• If a canopy or shower curtain enclosure is used, determine stability of the test aerosol concentration AFTER the employee enters the enclosure.
8. Have the employee enter the test enclosure and connect the respirator to the sample lines.
9. Immediately after entering the enclosure measure test aerosol concentration inside the respirator.
 
• Make sure the peak penetration does not exceed 5% for half facepieces, or 1% for full facepieces.
10. Have employee perform the appropriate fit-test exercises in Table 19.
 
• Do not adjust the respirator once exercises begin.
11. Calculate the overall fit factor as specified in Steps 12-13. The fit test is:
 
passed if the minimum fit factor of 100 for half facepieces or 500 for full facepieces is obtained
 
or
 
IF a passing fit factor is not obtained, the test has FAILED and you must have the employee select and test another respirator.
Calculations
 
Important!
 
• Do not count the grimace exercise measurements during these calculations
 
• Take into account the limitations of instrument detection when determining fit factors.
12. Calculate individual fit factors for each exercise by applying the following:
 
Exercise fit factor (ffE) = Average test enclosure concentration
 
 
 
 
 
 
Test aerosol concentration inside the respirator
 
• To determine the average test enclosure concentration use one of the following methods:
 
 
– Arithmetic average of the concentration before and after each test (an average of two values per entire test)
 
 
– Arithmetic average of concentration before and after each exercise (an average of two values per exercise)
 
 
– True average measured continuously during the respirator sample
 
• Determine the test aerosol concentration inside the respirator in one of the following ways:
 
 
– Average peak penetration values. Determine aerosol penetration for each exercise by:
 
 
 
■ Using integrators or computers that calculate the actual test agent penetration
 
 
 
or
 
 
 
■ Average the peak heights shown on the strip chart recording, graph, or by computer integration
 
 
– Maximum peak penetration. Use strip chart recordings to determine the highest peak penetration for each exercise and use this value
 
 
– Area under the peaks. Use computerized integration or other appropriate calculations to integrate the area under individual peaks for each exercise.
13. Using individual exercise fit factors (ffE) calculate the overall fit factor by doing all of the following:
 
• Convert each exercise fit factor to a penetration value
 
• Determine the average penetration value
 
• Convert the average penetration value back to a fit factor
 
or
 
Use this equation to calculate the overall fit factor:
 
 
 
Overall fit factor =
n
 
 
 
 
1/ffE1 + 1/ffE2 + 1/ffE3 . . . + 1/ffEn
 
 
 
 
Where:
 
 
 
 
n = The number of exercises;
 
 
 
 
ffE1 = The fit factor for the first exercise;
 
 
 
 
ffE2 = The fit factor for the second exercise;
 
 
 
 
ffE3 = The fit factor for the third exercise; and
 
 
 
 
ffEn = The fit factor for the nth exercise.
 
Table 19
Fit-Test Exercises
Important:
• This list applies when you use any fit test
• Employees tested must perform all exercises marked with an "X" as described for the fit-test procedure used
 
– Once exercises begin, any adjustments made void the test AND you must begin again
 
– After test exercises are completed, you must ask the employee about the comfort of the respirator. If it has become unacceptable, have the employee choose another one for testing
• When the controlled negative pressure procedure is used, STOP and repeat the test if the employee adjusts the respirator OR takes a breath and fails to hold it for 10 seconds
• Controlled negative pressure tests conducted according to the method published in 29 C.F.R. 1910.134, Appendix A are an acceptable alternative to the method outlined below.

1The Rainbow Passage:
"When the sunlight strikes raindrops in the air, they act like a prism and form a rainbow. The rainbow is a division of white light into many beautiful colors. These take the shape of a long round arch, with its path high above, and its two ends apparently beyond the horizon. There is, according to legend, a boiling pot of gold at one end. People look, but no one ever finds it. When a man looks for something beyond reach, his friends say he is looking for the pot of gold at the end of the rainbow."

Follow procedures established for cleaning and disinfecting respirators.

Follow the procedure in Table 20 for cleaning and disinfecting respirators.
Table 20
Respirator Cleaning Procedure
Step
Task
1.
Remove filters, cartridges, canisters, speaking diaphragms, demand and pressure valve assemblies, hoses, or any components recommended by the manufacturer.
 
 
• Discard or repair any defective parts.
2.
Wash components in warm (43°C (110°F) maximum) water with a mild detergent or with a cleaner recommended by the manufacturer
 
 
• A stiff bristle (not wire) brush may be used to help remove the dirt
 
 
• If the detergent or cleaner does not contain a disinfecting agent, respirator components should be immersed for two minutes in one of the following:
 
 
 
– A bleach solution (concentration of 50 parts per million of chlorine). Make this by adding approximately one milliliter of laundry bleach to one liter of water at 43°C (110°F)
 
 
 
– A solution of iodine (50 parts per million iodine). Make this in two steps:
 
 
 
 
■ First, make a tincture of iodine by adding 6-8 grams of solid ammonium iodide and/or potassium iodide to 100 cc of 45% alcohol approximately
 
 
 
 
■ Second, add 0.8 milliliters of the tincture to one liter of water at 43°C (110°F) to get the final solution
 
 
 
– Other commercially available cleansers of equivalent disinfectant quality when used as directed, if their use is recommended or approved by the respirator manufacturer.
3.
Rinse components thoroughly in clean, warm (43°C (110°F) maximum), preferably, running water.
 
Note:
The importance of thorough rinsing cannot be overemphasized. Detergents or disinfectants that dry on facepieces could cause dermatitis. In addition, some disinfectants may cause deterioration of rubber or corrosion of metal parts, if not completely removed.
4.
Drain components.
5.
Air-dry components or hand dry components with a clean, lint-free cloth.
6.
Reassemble the facepiece components.
 
 
• Replace filters, cartridges, and canisters, if necessary (for testing).
7.
Test the respirator to make sure all components work properly.

Follow procedures established for seal checking respirators.

Make sure employees perform a user seal check as outlined in Table 21 each time the respirator is worn, to make sure the seal is adequate.
IMPORTANT:
• You may use a seal check procedure recommended by the respirator manufacturer INSTEAD of the procedure outlined in Table 21 if you can demonstrate the procedure is based on a scientific study that, for example, demonstrates the procedure effectively identifies respirators that fit poorly when put on or adjusted.
Table 21
User Seal Check Procedure
Important information for employees:
 
• You need to conduct a seal check each time you put your respirator on BEFORE you enter the respirator use area. The purpose of a seal check is to make sure your respirator (which has been previously fit tested by your employer) is properly positioned on your face to prevent leakage during use and to detect functional problems
 
• The procedure below has two parts; a positive pressure check and a negative pressure check. You must complete both parts each time. It should only take a few seconds to perform, once you learn it
 
♦ If you cannot pass both parts, your respirator is NOT functioning properly, see your supervisor for further instruction.
Positive pressure check:
1. Remove exhalation valve cover, if removable.
2. Cover the exhalation valve completely with the palm of your hand WHILE exhaling gently to inflate the facepiece slightly.
3. The respirator facepiece should remain inflated (indicating a build-up of positive pressure and no outward leakage).
 
• If you detect no leakage, replace the exhalation valve cover (if removed), and proceed to conduct the negative pressure check
 
• If you detect evidence of leakage, reposition the respirator (after removing and inspecting it), and try the positive pressure check again.
Negative pressure check:
4. Completely cover the inhalation opening(s) on the cartridges or canister with the palm(s) of your hands WHILE inhaling gently to collapse the facepiece slightly.
 
• If you cannot use the palm(s) of your hands to effectively cover the inhalation openings on cartridges or canisters, you may use:
 
 
– Filter seal(s) (if available)
 
 
or
 
 
– Thin rubber gloves.
5. Once the facepiece is collapsed, hold your breath for 10 seconds WHILE keeping the inhalation openings covered.
6. The facepiece should remain slightly collapsed (indicating negative pressure and no inward leakage).
 
• If you detect NO evidence of leakage, the tightness of the facepiece is considered adequate, the procedure is completed, and you may now use the respirator
 
• If you detect leakage, reposition the respirator (after removing and inspecting it) and repeat both the positive and negative fit checks.
