     Hearing Location(s): Department of Labor and Industries Building, 7273 Linderson Way S.W., Room S117, Tumwater, WA 98501, on January 9, 2006, at 1:30 p.m.

     Date of Intended Adoption: April 4, 2006.

     Submit Written Comments to: Carol Stevenson, P.O. Box 44635, Olympia, WA 98504-4635, e-mail stei235@lni.wa.gov, fax (360) 902-5529, by January 17, 2006.

     Assistance for Persons with Disabilities: Contact Kimberly Johnson, (360) 902-5008, e-mail rhok235@lni.wa.gov by December 15, 2005.

     Purpose of the Proposal and Its Anticipated Effects, Including Any Changes in Existing Rules: The formaldehyde rules, in chapter 296-62 WAC, contain requirements relating to formaldehyde. These requirements will be rewritten and moved into chapter 296-856 WAC, Formaldehyde.

     Chapter 296-841 WAC, Respiratory hazards, requires that employees be notified of exposure results over the PEL within five days to meet the requirements of RCW 49-17-220 [49.17.220] for "prompt" notification. The chapter further specifies that notification for specific rules be "In writing, as specified in the rule specific to the substance." The requirement in the formaldehyde rule, proposed chapter 296-856 WAC, will require employers to notify employees of monitoring results within five days of receiving the results. Currently, the employers are required to provide notification within fifteen days. This requirement has been changed to be consistent with the notification times for substance-specific hygiene rules.

     There are no anticipated effects of this rule making.

     Statutory Authority for Adoption: RCW 49.17.010, 49.17.040, 49.17.050, 49.17.060.

     Statute Being Implemented: Chapter 49.17 RCW.

     Rule is not necessitated by federal law, federal or state court decision.

     Name of Proponent: Department of Labor and Industries, governmental.

     Name of Agency Personnel Responsible for Drafting: Tracy Spencer, Tumwater, (360) 902-5530; Implementation and Enforcement: Stephen Cant, Tumwater, (360) 902-5495.

     No small business economic impact statement has been prepared under chapter 19.85 RCW. RCW 19.85.030 (1)(a) requires a small business economic impact statement (SBEIS) only when a rule will "impose more than a minor cost on businesses in an industry." An analysis of the proposed rule reveals that in addition to not imposing new costs on businesses, these revisions will make WISHA rules easier for employers and employees to understand and use, and thus save time and resources. Therefore, no SBEIS is required.

     A cost-benefit analysis is not required under RCW 34.05.328. There are no costs to assess within these rule amendments. The amendments would require employers to provide notification of exposure evaluation results to employees within five days. Currently, employers are required to provide this information within fifteen days. This amendment will require employers to provide data that they already have, to employees quicker, and will not require additional costs. This amendment is consistent with notification times for substance-specific hygiene rules. The department determined the proposed changes do not require a cost-benefit analysis because the costs associated with the proposed changes are exempted by the law since they are clarifying the rule for ease of use and understanding. (See RCW 19.85.025 referencing RCW 34.05.310 (4)(d).)

AMENDATORY SECTION(Amending WSR 05-03-093, filed 1/18/05, effective 3/1/05)

WAC 296-62-07540   Formaldehyde.  

Note: The requirements in this chapter apply only to agriculture. The general industry requirements relating to formaldehyde have been moved to chapter 296-856 WAC, Formaldehyde.
     (1) Scope and application. This standard applies to all occupational exposures to formaldehyde, i.e., from formaldehyde gas, its solutions, and materials that release formaldehyde.

     (2) Definitions. For purposes of this standard, the following definitions shall apply:

     (a) "Action level" means a concentration of 0.5 part formaldehyde per million parts of air (0.5 ppm) calculated as an 8-hour time-weighted average (TWA) concentration.

     (b) "Approved" means approved by the director of the department of labor and industries or his/her authorized representative: Provided, however, That should a provision of this chapter state that approval by an agency or organization other than the department of labor and industries is required, such as Underwriters' Laboratories or the Mine Safety and Health Administration and the National Institute for Occupational Safety and Health, the provision of WAC 296-800-370 shall apply.

     (c) "Authorized person" means any person required by work duties to be present in regulated work areas, or authorized to do so by the employer, by this section of the standard, or by the WISHA Act.

     (d) "Director" means the director of the department of labor and industries, or his/her designated representative.

     (e) "Emergency" is any occurrence, such as but not limited to equipment failure, rupture of containers, or failure of control equipment that results in an uncontrolled release of a significant amount of formaldehyde.

     (f) "Employee exposure" means the exposure to airborne formaldehyde which would occur without corrections for protection provided by any respirator that is in use.

     (g) "Formaldehyde" means the chemical substance, HCHO, Chemical Abstracts Service Registry No. 50-00-0.

     (3) Permissible exposure limit (PEL).

     (a) TWA: The employer shall assure that no employee is exposed to an airborne concentration of formaldehyde which exceeds 0.75 part formaldehyde per million parts of air as an 8-hour TWA.

     (b) Short term exposure limit (STEL): The employer shall assure that no employee is exposed to an airborne concentration of formaldehyde which exceeds two parts formaldehyde per million parts of air (2 ppm) as a fifteen-minute STEL.

     (4) Exposure monitoring.

     (a) General.

     (i) Each employer who has a workplace covered by this standard shall monitor employees to determine their exposure to formaldehyde.

     (ii) Exception. Where the employer documents, using objective data, that the presence of formaldehyde or formaldehyde-releasing products in the workplace cannot result in airborne concentrations of formaldehyde that would cause any employee to be exposed at or above the action level or the STEL under foreseeable conditions of use, the employer will not be required to measure employee exposure to formaldehyde.

     (iii) When an employee's exposure is determined from representative sampling, the measurements used shall be representative of the employee's full shift or short-term exposure to formaldehyde, as appropriate.

     (iv) Representative samples for each job classification in each work area shall be taken for each shift unless the employer can document with objective data that exposure levels for a given job classification are equivalent for different workshifts.

     (b) Initial monitoring. The employer shall identify all employees who may be exposed at or above the action level or at or above the STEL and accurately determine the exposure of each employee so identified.

     (i) Unless the employer chooses to measure the exposure of each employee potentially exposed to formaldehyde, the employer shall develop a representative sampling strategy and measure sufficient exposures within each job classification for each workshift to correctly characterize and not underestimate the exposure of any employee within each exposure group.

     (ii) The initial monitoring process shall be repeated each time there is a change in production, equipment, process, personnel, or control measures which may result in new or additional exposure to formaldehyde.

     (iii) If the employer receives reports or signs or symptoms of respiratory or dermal conditions associated with formaldehyde exposure, the employer shall promptly monitor the affected employee's exposure.

     (c) Periodic monitoring.

     (i) The employer shall periodically measure and accurately determine exposure to formaldehyde for employees shown by the initial monitoring to be exposed at or above the action level or at or above the STEL.

     (ii) If the last monitoring results reveal employee exposure at or above the action level, the employer shall repeat monitoring of the employees at least every six months.

     (iii) If the last monitoring results reveal employee exposure at or above the STEL, the employer shall repeat monitoring of the employees at least once a year under worst conditions.

     (d) Termination of monitoring. The employer may discontinue periodic monitoring for employees if results from two consecutive sampling periods taken at least seven days apart show that employee exposure is below the action level and the STEL. The results must be statistically representative and consistent with the employer's knowledge of the job and work operation.

     (e) Accuracy of monitoring. Monitoring shall be accurate, at the ninety-five percent confidence level, to within plus or minus twenty-five percent for airborne concentrations of formaldehyde at the TWA and the STEL and to within plus or minus thirty-five percent for airborne concentrations of formaldehyde at the action level.

     (f) Employee notification of monitoring results. Within fifteen days of receiving the results of exposure monitoring conducted under this standard, the employer shall notify the affected employees of these results. Notification shall be in writing, either by distributing copies of the results to the employees or by posting the results. If the employee exposure is over either PEL, the employer shall develop and implement a written plan to reduce employee exposure to or below both PELs, and give written notice to employees. The written notice shall contain a description of the corrective action being taken by the employer to decrease exposure.

     (g) Observation of monitoring.

     (i) The employer shall provide affected employees or their designated representatives an opportunity to observe any monitoring of employee exposure to formaldehyde required by this standard.

     (ii) When observation of the monitoring of employee exposure to formaldehyde requires entry into an area where the use of protective clothing or equipment is required, the employer shall provide the clothing and equipment to the observer, require the observer to use such clothing and equipment, and assure that the observer complies with all other applicable safety and health procedures.

     (5) Regulated areas.

     (a) The employer shall establish regulated areas where the concentration of airborne formaldehyde exceeds either the TWA or the STEL and post all entrances and accessways with signs bearing the following information:

DANGER

FORMALDEHYDE

IRRITANT AND POTENTIAL CANCER HAZARD

AUTHORIZED PERSONNEL ONLY



     (b) The employer shall limit access to regulated areas to authorized persons who have been trained to recognize the hazards of formaldehyde.

     (c) An employer at a multiemployer worksite who establishes a regulated area shall communicate the access restrictions and locations of these areas to other employers with work operations at that worksite.

     (6) Methods of compliance.

     (a) Engineering controls and work practices. The employer shall institute engineering and work practice controls to reduce and maintain employee exposures to formaldehyde at or below the TWA and the STEL.

     (b) Exception. Whenever the employer has established that feasible engineering and work practice controls cannot reduce employee exposure to or below either of the PELs, the employer shall apply these controls to reduce employee exposures to the extent feasible and shall supplement them with respirators which satisfy this standard.

     (7) Respiratory protection.

     (a) General. For employees who use respirators required by this section, the employer must provide respirators that comply with the requirements of this subsection. Respirators must be used during:

     (i) Periods necessary to install or implement feasible engineering and work-practice controls;

     (ii) Work operations, such as maintenance and repair activities or vessel cleaning, for which the employer establishes that engineering and work-practice controls are not feasible;

     (iii) Work operations for which feasible engineering and work-practice controls are not yet sufficient to reduce exposure to or below the PELs;

     (iv) Emergencies.

     (b) Respirator program.

     (i) The employer must implement a respiratory protection program as required by chapter 296-842 WAC, except WAC 296-842-13005 and 296-842-14005.

     (ii) If air-purifying chemical-cartridge respirators are used, the employer must:

     (A) Replace the cartridge after three hours of use or at the end of the workshift, whichever occurs first, unless the cartridge contains a NIOSH-certified end-of-service-life indicator (ESLI) to show when breakthrough occurs.

     (B) Unless the canister contains a NIOSH-certified ESLI to show when breakthrough occurs, replace canisters used in atmospheres up to 7.5 ppm (10 x PEL) every four hours and industrial-sized canisters used in atmospheres up to 75 ppm (100 x PEL) every two hours, or at the end of the workshift, whichever occurs first.

     (c) Respirator selection.

     (i) The employer must select appropriate respirators from Table 1 of this section.

When protective equipment or clothing is provided under these provisions, the employer shall provide these protective devices at no cost to the employee and assure that the employee wears them.

     (a) Selection. The employer shall select protective clothing and equipment based upon the form of formaldehyde to be encountered, the conditions of use, and the hazard to be prevented.

     (i) All contact of the eyes and skin with liquids containing one percent or more formaldehyde shall be prevented by the use of chemical protective clothing made of material impervious to formaldehyde and the use of other personal protective equipment, such as goggles and face shields, as appropriate to the operation.

     (ii) Contact with irritating or sensitizing materials shall be prevented to the extent necessary to eliminate the hazard.

     (iii) Where a face shield is worn, chemical safety goggles are also required if there is a danger of formaldehyde reaching the area of the eye.

     (iv) Full body protection shall be worn for entry into areas where concentrations exceed 100 ppm and for emergency reentry into areas of unknown concentration.

     (b) Maintenance of protective equipment and clothing.

     (i) The employer shall assure that protective equipment and clothing that has become contaminated with formaldehyde is cleaned or laundered before its reuse.

     (12) Medical surveillance.

     (a) Employees covered.

     (i) The employer shall institute medical surveillance programs for all employees exposed to formaldehyde at concentrations at or exceeding the action level or exceeding the STEL.

     (ii) The employer shall make medical surveillance available for employees who develop signs and symptoms of overexposure to formaldehyde and for all employees exposed to formaldehyde in emergencies. When determining whether an employee may be experiencing signs and symptoms of possible overexposure to formaldehyde, the employer may rely on the evidence that signs and symptoms associated with formaldehyde exposure will occur only in exceptional circumstances when airborne exposure is less than 0.1 ppm and when formaldehyde is present in materials in concentrations less than 0.1 percent.

     (b) Examination by a physician. All medical procedures, including administration of medical disease questionnaires, shall be performed by or under the supervision of a licensed physician and shall be provided without cost to the employee, without loss of pay, and at a reasonable time and place.

     (c) Medical disease questionnaire. The employer shall make the following medical surveillance available to employees prior to assignment to a job where formaldehyde exposure is at or above the action level or above the STEL and annually thereafter. The employer shall also make the following medical surveillance available promptly upon determining that an employee is experiencing signs and symptoms indicative of possible overexposure to formaldehyde.

     (i) Administration of a medical disease questionnaire, such as in Appendix D, which is designed to elicit information on work history, smoking history, any evidence of eye, nose, or throat irritation; chronic airway problems or hyperreactive airway disease; allergic skin conditions or dermatitis; and upper or lower respiratory problems.

     (ii) A determination by the physician, based on evaluation of the medical disease questionnaire, of whether a medical examination is necessary for employees not required to wear respirators to reduce exposure to formaldehyde.

     (d) Medical examinations. Medical examinations shall be given to any employee who the physician feels, based on information in the medical disease questionnaire, may be at increased risk from exposure to formaldehyde and at the time of initial assignment and at least annually thereafter to all employees required to wear a respirator to reduce exposure to formaldehyde. The medical examination shall include:

     (i) A physical examination with emphasis on evidence of irritation or sensitization of the skin and respiratory system, shortness of breath, or irritation of the eyes.

     (ii) Laboratory examinations for respirator wearers consisting of baseline and annual pulmonary function tests. As a minimum, these tests shall consist of forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and forced expiratory flow (FEF).

     (iii) Any other test which the examining physician deems necessary to complete the written opinion.

     (iv) Counseling of employees having medical conditions that would be directly or indirectly aggravated by exposure to formaldehyde on the increased risk of impairment of their health.

     (e) Examinations for employees exposed in an emergency. The employer shall make medical examinations available as soon as possible to all employees who have been exposed to formaldehyde in an emergency.

     (i) The examination shall include a medical and work history with emphasis on any evidence of upper or lower respiratory problems, allergic conditions, skin reaction or hypersensitivity, and any evidence of eye, nose, or throat irritation.

     (ii) Other examinations shall consist of those elements considered appropriate by the examining physician.

     (f) Information provided to the physician. The employer shall provide the following information to the examining physician:

     (i) A copy of this standard and Appendices A, C, D, and E;

     (ii) A description of the affected employee's job duties as they relate to the employee's exposure to formaldehyde;

     (iii) The representative exposure level for the employee's job assignment;

     (iv) Information concerning any personal protective equipment and respiratory protection used or to be used by the employee; and

     (v) Information from previous medical examinations of the affected employee within the control of the employer.

     (vi) In the event of a nonroutine examination because of an emergency, the employer shall provide to the physician as soon as possible: A description of how the emergency occurred and the exposure the victim may have received.

     (g) Physician's written opinion.

     (i) For each examination required under this standard, the employer shall obtain a written opinion from the examining physician. This written opinion shall contain the results of the medical examination except that it shall not reveal specific findings or diagnoses unrelated to occupational exposure to formaldehyde. The written opinion shall include:

     (A) The physician's opinion as to whether the employee has any medical condition that would place the employee at an increased risk of material impairment of health from exposure to formaldehyde;

     (B) Any recommended limitations on the employee's exposure or changes in the use of personal protective equipment, including respirators;

     (C) A statement that the employee has been informed by the physician of any medical conditions which would be aggravated by exposure to formaldehyde, whether these conditions may have resulted from past formaldehyde exposure or from exposure in an emergency, and whether there is a need for further examination or treatment.

     (ii) The employer shall provide for retention of the results of the medical examination and tests conducted by the physician.

     (iii) The employer shall provide a copy of the physician's written opinion to the affected employee within fifteen days of its receipt.

     (h) Medical removal.

     (i) The provisions of this subdivision apply when an employee reports significant irritation of the mucosa of the eyes or of the upper airways, respiratory sensitization, dermal irritation, or dermal sensitization attributed to workplace formaldehyde exposure. Medical removal provisions do not apply in case of dermal irritation or dermal sensitization when the product suspected of causing the dermal condition contains less than 0.05% formaldehyde.

     (ii) An employee's report of signs or symptoms of possible overexposure to formaldehyde shall be evaluated by a physician selected by the employer pursuant to (c) of this subsection. If the physician determines that a medical examination is not necessary under (c)(ii) of this subsection, there shall be a two-week evaluation and remediation period to permit the employer to ascertain whether the signs or symptoms subside untreated or with the use of creams, gloves, first-aid treatment, or personal protective equipment. Industrial hygiene measures that limit the employee's exposure to formaldehyde may also be implemented during this period. The employee shall be referred immediately to a physician prior to expiration of the two-week period if the signs or symptoms worsen. Earnings, seniority, and benefits may not be altered during the two-week period by virtue of the report.

     (iii) If the signs or symptoms have not subsided or been remedied by the end of the two-week period, or earlier if signs or symptoms warrant, the employee shall be examined by a physician selected by the employer. The physician shall presume, absent contrary evidence, that observed dermal irritation or dermal sensitization are not attributable to formaldehyde when products to which the affected employee is exposed contain less than 0.1% formaldehyde.

     (iv) Medical examinations shall be conducted in compliance with the requirements of (e)(i) and (ii) of this subsection. Additional guidelines for conducting medical exams are contained in WAC 296-62-07546, Appendix C.

     (v) If the physician finds that significant irritation of the mucosa of the eyes or the upper airways, respiratory sensitization, dermal irritation, or dermal sensitization result from workplace formaldehyde exposure and recommends restrictions or removal. The employer shall promptly comply with the restrictions or recommendations of removal. In the event of a recommendation of removal, the employer shall remove the affected employee from the current formaldehyde exposure and if possible, transfer the employee to work having no or significantly less exposure to formaldehyde.

     (vi) When an employee is removed pursuant to item (v) of this subdivision, the employer shall transfer the employee to comparable work for which the employee is qualified or can be trained in a short period (up to six months), where the formaldehyde exposures are as low as possible, but not higher than the action level. The employer shall maintain the employee's current earnings, seniority, and other benefits. If there is no such work available, the employer shall maintain the employee's current earnings, seniority, and other benefits until such work becomes available, until the employee is determined to be unable to return to workplace formaldehyde exposure, until the employee is determined to be able to return to the original job status, or for six months, whichever comes first.

     (vii) The employer shall arrange for a follow-up medical examination to take place within six months after the employee is removed pursuant to this subsection. This examination shall determine if the employee can return to the original job status, or if the removal is to be permanent. The physician shall make a decision within six months of the date the employee was removed as to whether the employee can be returned to the original job status, or if the removal is to be permanent.

     (viii) An employer's obligation to provide earnings, seniority, and other benefits to a removed employee may be reduced to the extent that the employee receives compensation for earnings lost during the period of removal either from a publicly or employer-funded compensation program or from employment with another employer made possible by virtue of the employee's removal.

     (ix) In making determinations of the formaldehyde content of materials under this subsection the employer may rely on objective data.

     (i) Multiple physician review.

     (i) After the employer selects the initial physician who conducts any medical examination or consultation to determine whether medical removal or restriction is appropriate, the employee may designate a second physician to review any findings, determinations, or recommendations of the initial physician and to conduct such examinations, consultations, and laboratory tests as the second physician deems necessary and appropriate to evaluate the effects of formaldehyde exposure and to facilitate this review.

     (ii) The employer shall promptly notify an employee of the right to seek a second medical opinion after each occasion that an initial physician conducts a medical examination or consultation for the purpose of medical removal or restriction.

     (iii) The employer may condition its participation in, and payment for, the multiple physician review mechanism upon the employee doing the following within fifteen days after receipt of the notification of the right to seek a second medical opinion, or receipt of the initial physician's written opinion, whichever is later:

     (A) The employee informs the employer of the intention to seek a second medical opinion; and

     (B) The employee initiates steps to make an appointment with a second physician.

     (iv) If the findings, determinations, or recommendations of the second physician differ from those of the initial physician, then the employer and the employee shall assure that efforts are made for the two physicians to resolve the disagreement. If the two physicians are unable to quickly resolve their disagreement, then the employer and the employee through their respective physicians shall designate a third physician who shall be a specialist in the field at issue:

     (A) To review the findings, determinations, or recommendations of the prior physicians; and

     (B) To conduct such examinations, consultations, laboratory tests, and discussions with prior physicians as the third physician deems necessary to resolve the disagreement of the prior physicians.

     (v) In the alternative, the employer and the employee or authorized employee representative may jointly designate such third physician.

     (vi) The employer shall act consistent with the findings, determinations, and recommendations of the third physician, unless the employer and the employee reach an agreement which is otherwise consistent with the recommendations of at least one of the three physicians.

     This part applies only if your employees:

     • Are exposed to a respiratory hazard

     OR

     • Could be exposed to one of the specific hazards listed below.

     This part applies to any workplace with potential or actual employee exposure to respiratory hazards. It requires you to protect employees from respiratory hazards by applying this protection strategy:

     • Evaluate employee exposures to determine if controls are needed

     • Use feasible controls. For example, enclose or confine the operation, use ventilation systems, or substitute with less toxic material

     • Use respirators if controls are not feasible or if they cannot completely remove the hazard.

     Definition:

     Exposed or exposure:

     The contact an employee has with a toxic substance, harmful physical agent or oxygen deficient condition, whether or not protection is provided by respirators or other personal protective equipment (PPE). Exposure can occur through various routes of entry, such as inhalation, ingestion, skin contact, or skin absorption.

Note: Examples of substances that may be respiratory hazards when airborne include:
• Chemicals listed in Table 3
• Any substance
– Listed in the latest edition of the NIOSH Registry of Toxic Effects of Chemical Substances
– For which positive evidence of an acute or chronic health hazard exists through tests conducted by, or known to, the employer

WAC 296-307-62625   Permissible exposure limits of air contaminants.  

     IMPORTANT:

     The following information applies to Table 3, Permissible Exposure Limits for Air Contaminants.

     • Exposure needs to be determined from personal air samples taken in the breathing zone or from monitoring representative of the employee's breathing zone.

     • Ppm refers to parts of vapor or gas per million parts of air by volume, at 25 degrees C and 760 mm Hg pressure.

     • Mg/m3 refers to milligrams of substance per cubic meter of air.

     • For a metal that is measured as the metal itself, only the CAS number for the metal is given. The CAS numbers for individual compounds of the metal are not provided. For more information about CAS registry numbers see the web site: http://www.cas.org.

     • Time weighted averages (TWA8) represent the maximum allowed average exposure for any 8-hour time period. For work periods longer than 8 hours the TWA8 needs to be determined using the 8 continuous hours with the highest average concentration.

     • Short-term exposure limits (STEL) represent maximum allowed average exposure for any fifteen-minute period, unless another time period is noted in Table 3.

     • The ceiling represents the maximum allowed exposure for the shortest time period that can feasibly be measured.

     • An "X" in the "skin" column indicates the substance can be absorbed through the skin, either by airborne or direct contact.

     • Requirements for the use of gloves, coveralls, goggles, and other personal protective equipment can be found in WAC 296-307-100.

     • The respirable fraction of particulate is measured by sampling with a size-selector having the following characteristics:


Mean aerodynamic diameter in micrometers Percent passing the selector

     &sqbul; Equipment.

     – You have any reason to suspect new or increased employee exposure may occur.

     – You receive a report of employee developing signs and symptoms associated with formaldehyde exposure.

     You must:

     • Provide affected employees or their designated representatives an opportunity to observe exposure monitoring required by this chapter.

     • Make sure observers entering areas with formaldehyde exposure:

     – Are provided with and use the same protective clothing, respirators, and other personal protective equipment (PPE) that employees working in the area are required to use;

     AND

     – Follow any safety and health requirements that apply.

     Exposure evaluation process:

Exemption: • Exposure monitoring is not necessary if you have documentation conclusively demonstrating that employee exposure for a particular material and the operation where it is used, cannot exceed the action level (AL) or short-term exposure limit (STEL) during any conditions reasonably anticipated.
• Such documentation can be based on observations, data, calculations, and previous air monitoring results. Previous air monitoring results:
– Must meet the accuracy required by Step 5.
– Must be based on data that represents conditions being evaluated in your workplace.
– May be from outside sources, such as industry or labor studies.
     Step 1: Identify all employees who have potential exposure to airborne formaldehyde in your workplace.

     Step 2: Identify operations where employee exposures could exceed the 15-minute short-term exposure limit (STEL) for formaldehyde of 2 parts per million (ppm).

Note: You may use monitoring devices such as colorimetric indicator tubes or real-time monitors to screen for activities where employee exposures could exceed the STEL.
     Step 3: Select employees from those working in the operations you identified in Step 2 who will have their 15-minute exposures monitored.

     Step 4: Select employees from those identified in Step 1 who will have their 8-hour exposures monitored.

     – Make sure the exposures of the employees selected represent 8-hour exposures for all employees identified in Step 1, including each job activity, work area, and shift.

     &sqbul; If you expect exposures to be below the action level (AL), you may limit your selection to those employees reasonably believed to have the highest exposures.

     &sqbul; If you find any of those employees' exposure to be above the AL, then you need to repeat monitoring to include each job activity, work area, and shift.

Reference: A written description of the procedure used for obtaining representative employee exposure monitoring results needs to be kept as part of your exposure records, as required by Exposure records, WAC 296-856-20070.
     – This description can be created while completing Steps 3 through 6 of this exposure evaluation process.

     Step 5: Determine how you will obtain accurate employee exposure monitoring results. Select and use an air monitoring method with a confidence level of 95 percent, that is accurate to:

     – ±25 percent when concentrations are potentially above the TWA of 0.75 parts per million (ppm).

     – ±25 percent when concentrations are potentially above the STEL of 2 ppm.

     – ±35 percent when concentrations are potentially above the AL.

Note: • Here are examples of air monitoring methods that meet this accuracy requirement:
– OSHA Method 52 found at http://www.osha.gov/dts/sltc/methods/toc.html.
– NIOSH methods: 2016, 2514, 3500, 2539, and 5700, found at http://www.cdc.gov/niosh/homepage.html and linking to the NIOSH Manual of Analytical Methods.
– Direct reading methods found at http://www.osha.gov/SLTC/formaldehyde/index.html
     Step 6: Obtain employee exposure monitoring results by collecting air samples to accurately determine the formaldehyde exposure of employees identified in Steps 3 and 4.

     – Make sure samples are collected from each selected employee's breathing zone.

Note: • You may use any sampling method that meets the accuracy specified in Step 5. Examples of these methods include:
– Real-time monitors that provide immediate exposure monitoring results.
– Equipment that collects samples that are sent to a laboratory for analysis.
• The following are examples of methods for collecting samples representative of 8-hour exposures.
– Collect one or more continuous samples, such as a single 8-hour sample or four 2-hour samples.
– Take a minimum of 5 brief samples, such as five 15-minute samples, during the work shift at randomly selected times.
• For work shifts longer than 8 hours, monitor the continuous 8-hour portion of the shift expected to have the highest average exposure concentration.
     Step 7: Have the samples you collected analyzed to obtain employee exposure monitoring results for 8-hour and short-term exposure limits (STEL) exposures.

     – Determine if employee exposure monitoring results are above or below the following values:

     &sqbul; 8-hour action level (AL) of 0.5 ppm.

     &sqbul; 8-hour time-weighted average (TWA8) of 0.75 ppm.

     &sqbul; 15-minute short-term exposure limit (STEL) of 2 ppm.

Reference: To use the monitoring results to determine which additional chapter sections apply to employee exposure in your workplace, turn to the Scope, WAC 296-856-100, and follow Table 1 in that section.
Note: • You may contact your local WISHA consultant for help with:
– Interpreting data or other information.
– Determining 8-hour employee exposure monitoring results.
• To contact a WISHA consultant:
– Go to the safety and health core rules, chapter 296-800 WAC;
AND
– Find the resources section, and under "other resources," find service locations for labor and industries.

NEW SECTION
WAC 296-856-30030   Medical removal.  

Exemption: Medical removal or restrictions do not apply when skin irritation or skin sensitization occurs from products that contain less than 0.05 percent of formaldehyde.
     IMPORTANT:

     • This section applies when an employee reports irritation of the mucosa of the eye or the upper airways, respiratory sensitization, dermal irritation, or skin sensitization from formaldehyde exposure.

     • When determining the content of formaldehyde in materials that employees have exposure to, you may use documentation, such as manufacturer's data, or independent laboratory analyses.

     You must:

     • Complete Steps 1 through 4 of the medical evaluation process for removal of employees, in this section, for employees that report signs and symptoms of formaldehyde exposure.

Note: When the employee is exposed to products containing less than 0.1 percent formaldehyde, the LHCP can assume, absent of contrary evidence, that employee signs and symptoms are not due to formaldehyde exposure.
     Medical evaluation process for removal of employees:

     Step 1: Provide the employee with a medical evaluation by an LHCP selected by the employer.

     Step 2: Based on information in the medical questionnaire the LHCP will determine if the employee will receive an examination as described in Table 3, Content of Medical Evaluations, in Medical and emergency evaluations, WAC 296-856-30020.

     – If the LHCP determines that a medical examination is not necessary, there will be a two-week evaluation and correction period to determine whether the employee's signs and symptoms resolve without treatment, from the use of creams, gloves, first-aid treatment, personal protective equipment, or industrial hygiene measures that reduce exposure.

     &sqbul; If before the end of the two-week period the employee's signs or symptoms worsen, immediately refer them back to the LHCP.

     &sqbul; If signs and symptoms persist after the two-week period, the LHCP will administer a physical examination as outlined in Table 3, Content of Medical Evaluations, in Medical and emergency evaluations, WAC 296-856-30020.

     Step 3: Promptly follow the LHCP's restrictions or recommendations. If the LHCP recommends removal from exposure, do either of the following:

     – Transfer the employee to a job currently available that:

     &sqbul; The employee qualifies for, or could be trained for, in a short period of time (up to six months);

     AND

     &sqbul; Will keep the employee's exposure to as low as possible, and never above the AL of 0.5 parts per million.

     – Remove the employee from the workplace until either:

     &sqbul; A job becomes available that the employee qualifies for, or could be trained for in a short period of time and will keep the employee's exposure to as low as possible and never above the AL;

     OR

     &sqbul; The employee is returned to work or permanently removed from formaldehyde exposure, as determined by completing Steps 1 through 3 of the medical evaluation process for removal of employees, in this section.

     Step 4: Make sure the employee receives a follow-up examination within six months from being removed from the formaldehyde exposure by the LHCP. At this time, the LHCP will determine if the employee can return to their original job status, or if the removal is permanent.

     You must:

     • Maintain the employee's current pay rate, seniority, and other benefits if:

     – You move them to a job that they qualify for, or could be trained in a short period of time, and will keep the employee's exposure to as low as possible and never above the AL;

     OR

     – In the case there is no such job available, then until they are able to return to their original job status or after six months, which ever comes first.

Note: • If you must provide medical removal benefits and the employee will receive compensation for lost pay from other sources, you may reduce your medical removal benefit obligation to offset the amount provided by these sources.
• Examples of other sources are:
– Public or employer-funded compensation programs.
– Employment by another employer, made possible by the employee's removal.
     • Make medical evaluations available:

     – At no cost to employees, including travel costs and wages associated with any time spent obtaining the medical examinations and evaluations.

     – At reasonable times and places.

     You must:

     • Promptly notify employees that they may seek a second medical opinion from an LHCP of their choice, each time a medical examination or consultation is conducted by an LHCP selected by the employer to evaluate medical removal.

     – At a minimum, this notification must include the details of your multiple physician review process.

Note: Notification may be provided in writing or by verbal communication.
     You must:

     • Complete requirements in the multiple LHCP review process once you have been informed of an employee's decision to seek a second medical opinion.

     • Pay for and complete the multiple LHCP review process for employees who:

     – Inform you in writing or by verbal communication that they will seek a second medical opinion.

     – Initiate steps to make an appointment with the LHCP they select. This LHCP will be referred to as the second LHCP.

     – Fulfill the previous actions to inform you, and initiate steps for an appointment, within fifteen days from receiving either your notification or the initial LHCP's written opinion, whichever is received later.

Note: This process allows for selection of a second LHCP and, when disagreements between LHCPs persist, for selection of a third LHCP.
     Multiple LHCP review process:

     Step 1: Make sure the information required by Step 4 of the medical evaluation process is received by the second LHCP. This process is located in the section, Medical and emergency evaluations, WAC 296-856-30020.

     – This requirement also applies when a third LHCP is selected.

     Step 2: Allow the second LHCP to:

     – Review findings, determinations, or recommendations from the original LHCP you selected;

     AND

     – Conduct medical examinations, consultations, and laboratory tests as necessary to complete their review.

     Step 3: Obtain a written opinion from the second LHCP and make sure the employee receives a copy within five business days from the date you receive it. If findings, determinations, and recommendations in the written opinion are:

     – Consistent with the written opinion from the initial LHCP, you can end the multiple physician review process. Make sure you follow the LHCP's recommendations.

     – Inconsistent with the written opinion from the initial LHCP, then you and the employee must make sure efforts are made for the LHCPs to resolve any disagreements.

     &sqbul; If the LHCPs quickly resolve disagreements, you can end the multiple physician review process. Make sure you follow the LHCP's recommendations.

     &sqbul; If disagreements are not resolved within thirty days, continue to Step 4.

     Step 4: You and the employee must work through your respective LHCPs to agree on the selection of a third LHCP, or work together to designate a third LHCP to:

     – Review findings, determinations, or recommendations from the initial and second LHCP;

     AND

     – Conduct medical examinations, consultations, and laboratory tests as necessary to resolve disagreements between the initial and second LHCP.

     Step 5: Obtain a written opinion from the third LHCP and make sure the employee receives a copy within five business days from the day you receive it.

     – Follow the third LHCP's recommendations, unless you and the employee agree to follow recommendations consistent with at least one of the three LHCPs.

     Uncontrolled release

     A release where significant safety and health risks could be created. Releases of hazardous substances that are either incidental or could not create a safety or health hazard (i.e., fire, explosion, or chemical exposure) are not considered to be uncontrolled releases.

     Examples of conditions that could create a significant safety and health risk are:

     • Large-quantity releases.

     • Small releases that could be highly toxic.

     • Potentially contaminated individuals arriving at hospitals.

     • Airborne exposures that could exceed a WISHA permissible exposure limit or a published exposure limit and employees are not adequately trained or equipped to control the release.
