PERMANENT RULES
LABOR AND INDUSTRIES
Date of Adoption: August 8, 2001.
Purpose: Chapter 296-307 WAC, Safety standards for agriculture and minor housekeeping changes throughout chapters 296-24, 296-36, 296-45, 296-54, 296-56, 296-62, 296-78, 296-155 and 296-350 WAC, WISHA administrative rules.
As a result of the new safety and health core rules, chapter 296-800 WAC, which were adopted on May 9, 2001, additional clarifying and housekeeping changes were needed. The majority of the changes are references that needed to be updated throughout WISHA's other rules. Also, the agricultural industry voiced their concern at the public hearings for the Safety and Health Core Rules that some of the core rules would apply to them. We subsequently met with stakeholders in the agricultural industry to address their concerns. It was agreed that some of the rules in the safety and health core rule book, which were taken from chapter 296-62 WAC, General occupational health standards, should be included in chapter 296-307 WAC, Safety standards for agriculture. They are:
| Employer chemical hazard communication. | |
| Lighting. | |
| Environmental tobacco smoke. |

Statutory Authority for Adoption: RCW 49.17.010, [49.17].040, and [49.17].050.
Adopted under notice filed as WSR 01-12-103 on June 20 [6], 2001.
Changes Other than Editing from Proposed to Adopted Version: As a result of written and oral comments received, the following changes are as a result of the public hearings, to clarify language or for better organization:
WAC 296-307-039 First aid rule summary.
| Added the words "first aid" to the title of this section. | |
| In the definition of "first aid" removed the following language, "Tests, such as X rays, must not be confused with treatment. For example, an employee thought he broke his arm and went to the hospital to get X rays. If the X rays show no broken bones, they are not considered first aid. On the other hand, if they do show a broken bone, they would be considered medical treatment." | |
| Deleted the definition of "First-aid station." |
| Modified the first bullet in this section to read, "Make sure that every two years, employees successfully complete first-aid training in the following core elements:" |
| Removed the language in the first-aid kit table relating to "ten package," "24 package" and "36 package" and replaced it with "first-aid kit." Also, added a reference in the table to see "WAC 296-307-03925" for first-aid station requirements. | |
| Added a note that reads, "Kits should be checked at least weekly to ensure adequate number of needed items are available." | |
| Added a note that reads, "Kits may be carried in any motor vehicle that is used near the crew." |
| Delete the requirement relating to the first-aid station having to be "well marked." |
| Modified the language in the second bullet to read, "Make sure that employees, who must travel between workplaces during a work shift, such as when their work is carried out at more than one geographical location, can immediately obtain the required MSDS information in an emergency. (MSDSs may be kept at a central location at the primary workplace facility and accessed by means such as voice communication or laptop computer.)" |
| Added the following note that reads, "The Employer Chemical Hazard Communication information and training requirements also apply to pesticides. Employers who have employees who are exposed to pesticides must be in compliance with this rule and the Worker protection standards, WAC 296-307-12040." |
Number of Sections Adopted in Order to Comply with Federal Statute: New 0, Amended 0, Repealed 0; Federal Rules or Standards: New 0, Amended 0, Repealed 0; or Recently Enacted State Statutes: New 0, Amended 0, Repealed 0.
Number of Sections Adopted at Request of a Nongovernmental Entity: New 0, Amended 0, Repealed 0.
Number of Sections Adopted on the Agency's Own Initiative: New 24, Amended 44, Repealed 11.
Number of Sections Adopted in Order to Clarify, Streamline, or Reform Agency Procedures: New 24, Amended 44, Repealed 11.
Number of Sections Adopted Using Negotiated Rule Making: New 0, Amended 0, Repealed 0; Pilot Rule Making: New 0, Amended 0, Repealed 0; or Other Alternative Rule Making: New 24, Amended 44, Repealed 11.
Other Findings Required by Other Provisions of Law as Precondition to Adoption or Effectiveness of Rule: The
environmental tobacco smoke, lighting and hazard communication
requirements from chapter 296-62 WAC, General occupational health
standards, were incorporated into chapter 296-800 WAC, Safety and
health core rules, which were adopted on May 9, 2001, and
effective on September 1, 2001. Even though chapter 296-800 WAC
was adopted, the agriculture industry is required to follow rules
in chapter 296-62 WAC. Since the requirements were removed from
chapter 296-62 WAC with the safety and health core rule filing we
need to incorporate these requirements into chapter 296-307 WAC,
Safety standards for agriculture. As a result, the effective
date for these rules will be September 1, 2001, which is less
than the required thirty day time period normally followed, RCW 34.05.380. The department believes the earlier effective date is
necessary because of imminent peril to the public health, safety,
or welfare and to ensure continued protection for the agriculture
industry.
Effective Date of Rule:
September 1, 2001.

Choose one of the following two options to make sure that your employees have access to personnel who are trained in first aid.
Option 1:
Make sure first-aid trained persons are in your workplace to help your employees if they become hurt or ill on the job by doing the following:
- Make sure that:
⧫ Each person in charge of employees has first-aid training; or
⧫ Another person with first-aid training is present or available to your employees, whenever you have 2 or more employees present.
| Note: | This rule is met if persons other than an employee, such as the farm operator or spouse, hold a current first-aid certificate and are available during working hours. |
| EXCEPTION: | This rule does not apply to individual employees whose duties require them to work alone at isolated workstations. However, employees working alone must be checked at intervals by some method agreed upon by you and the employee. |
Option 2:
Develop and maintain a written first-aid response plan for your workplace. If you choose this option, you must do all of the following:
- Determine how many, if any, employees should be trained in first aid, based on the following factors:

PART Y - OCCUPATIONAL HEALTH STANDARDSThousands of chemicals can be found in today's workplaces. These chemicals may have the capacity to cause health problems, from minor skin irritations to serious injuries or diseases like cancer.
The employer chemical hazard communication rule was developed to make sure employers and employees are informed about chemical hazards in the workplace.
This rule applies to:
Employers engaged in businesses where chemicals are used, distributed, or produced for use or distribution.
Contractors or subcontractors that work for employers engaged in businesses where chemicals are used, distributed, or produced for use or distribution.
| Note: |
| If you produce, import, distribute and/or repackage chemicals, or choose not to rely on labels or material safety data sheets provided by the manufacturer or importer, you must comply with Chemical hazard communication for manufacturers, importers and distributors, WAC 296-62-054. |
| You may withhold trade secret information under certain circumstances, see Trade secrets, WAC 296-62-053, to find out what information may be withheld as a trade secret and what information must be released. |
| EXEMPTIONS: |
| For the purposes of this employer hazard communication rule, if you are engaged in agricultural production of crops or livestock, "employee" does not mean: | |
| - Immediate family members of the officers of any corporation, partnership, sole proprietorship or other business entity or officers of any closely held corporation. |
| Certain products, chemicals, or items are exempt from this rule. Below is a summarized list of these exemptions. See WAC 296-307-55055 at the end of this rule to get complete information about these exemptions: | |
| - Any hazardous waste or substance | |
| - Tobacco or tobacco products | |
| - Wood or wood products that are not chemically treated and will not be processed, for example, by sawing and sanding | |
| - Food or alcoholic beverages | |
| - Some drugs, such as retail or prescription medications | |
| - Retail cosmetics | |
| - Ionizing and nonionizing radiation | |
| - Biological hazards | |
| - Any consumer product or hazardous substance when workplace exposure is the same as that of a consumer | |
| ⧫ Retail products used in offices in the same manner and frequency used by consumers can be termed "consumer products." Consumer products include things such as: Correction fluid, glass cleaner, and dishwashing liquid. |
| Example: | If you use a household cleaner in your workplace in the same way that a consumer would use it when cleaning their house, the exposure should be the same as the consumer's. ("In the same way" means using the household cleaner in the same manner and frequency.) A janitor using a household cleaner, such as bleach, throughout the day, is not considered to be consumer use. |
| Manufactured items that remain intact are exempt for this rule. | |
| The following are examples: |
| Item | Covered by this rule | Not covered by this rule |
| Brick | sawed or cut in half | used whole or intact |
| Pipe | cut by a torch | bent with a tube bender |
| Nylon rope | burning the ends | tying a knot |
| Manufactured items that are fluids or in the form of particles are not exempt for this rule. |

Attempt to obtain a material safety data sheet (MSDS) upon request
Exemption: Items or chemicals exempt from the rule, and exemptions from labeling
Definitions
[]
Develop, implement, maintain, and make available a written Chemical Hazard Communication Program specifically for your workplace. The Chemical Hazard Communication Program must, at a minimum, include:
- A list of hazardous chemicals known to be present in your workplace
- Procedures for making sure all containers are properly labeled
- A description of how you are going to obtain and maintain your material safety data sheets (MSDSs)
- A description of how you are going to train and inform your employees about hazardous chemicals in their workplace
- A description of how you are going to inform your employees about:
⧫ Chemical hazards used during nonroutine tasks
⧫ The hazards associated with chemicals contained in unlabeled pipes in their work areas
You must:
Make sure your written Chemical Hazard Communication Program includes the following communication methods you will apply if you produce, use, or store hazardous chemicals at your workplace(s) in such a way that the employees of other employer(s) may be exposed:
- Provide the other employer(s) with a copy of the relevant material safety data sheets (MSDSs), or provide access to the MSDSs in a central location at the workplace
- Inform the other employer(s) of any precautionary measures that need to be taken to protect employees during normal operating conditions and in foreseeable emergencies
- Describe how to inform the other employer(s) of the labeling system used in the workplace
| Note: | |
| Examples of employees of other employers who could be exposed to chemical hazards that you produce, use, or store in your workplace include employees of construction companies, cleaning services, or maintenance contractors visiting or working on-site. | |
| Your employees have the right to get chemical hazard communication information from other employers at workplaces where they are working; and employees of other employers have the right to get the information from you when they are working at your workplace. | |
| Include in your written Chemical Hazard Communication Program the methods that you will use to share information with other employers and their employees at your workplace(s) regarding: | |
| Access to MSDSs | |
| Precautionary measures such as personal protective equipment (PPE) and emergency plans | |
| Any labeling systems used at the workplace. | |
| If you rely on another employer's chemical hazard communication program to share the information required and the program meets the requirements of this rule, document in your own written Chemical Hazard Communication Program. |
Make your Chemical Hazard Communication Program available to your employees.
| Note: | Where employees must travel between workplaces during a workshift, that is, if their work is carried out at more than one geographical location, the written Chemical Hazard Communication Program may be kept at the primary workplace facility. |
[]
Identify all hazardous chemicals in your workplace. This includes any chemical that is known to be present in your workplace in such a way that employees may be exposed to it under normal conditions of use or in a foreseeable emergency.
Create a list of these chemicals using the chemical or common name on the material safety data sheet (MSDS). This list:
Must be compiled for the workplace as a whole, or for individual work areas.
Is necessary to make sure that all hazardous chemicals are identified and that MSDS, and labeling rules are met.
Must be current.
| Note: | The following are some ways to determine whether a product is hazardous: |
| Look for words on the label, such as "CAUTION," "WARNING," or "DANGER." |
| Look for words or "hazard coding" that indicate that the chemical is flammable, an irritant, corrosive, carcinogenic, etc. "Hazard coding" refers to words, numbers, or colors that tell you a chemical is dangerous. |
| Check the product's MSDS for hazard information. | |
| Examples of hazardous chemicals are: Acids, adhesives, caustics, fuels, paints, varnishes, shellacs and pesticides. Too many other classes of hazardous chemicals exist to list them all here. If you have any questions about a chemical you have at your workplace, contact your local L&I office. |
[]
Obtain a MSDS for each hazardous chemical used as soon as possible if the MSDS is not provided with the shipment of a hazardous chemical from the chemical manufacturer or importer.
| Note: |
| To obtain a MSDS, you may try calling the manufacturer or checking their website. |
| If you have a commercial account with a retailer or wholesaler, you have the right to request and receive a MSDS about hazardous chemicals you purchase. |
| If a chemical is purchased from a retailer with no commercial accounts, you have the right to request and receive the manufacturer's name and address so that you can contact them and request a MSDS for the chemical. |
| Whoever prepares the MSDS is required to mark all blocks on the form, even if there is no relevant information for that section. |
| If you have problems getting a MSDS within 30 calendar days after making a written request to the chemical manufacturer, importer, or distributor, you can get help from WISHA. You may contact your local regional office for assistance or make a written request for assistance to the: | |
| Department of Labor and Industries | |
| Right-to-Know Program P.O. Box 44610 |
|
| Olympia, Washington 98504-4610 |
| Include in your request: |
| A copy of the purchaser's written request to the chemical manufacturer, importer, or distributor |
| The name of the product suspected of containing a hazardous chemical |
| The identification number of the product, if available |
| A copy of the product label, if available |
| The name and address of the chemical manufacturer, importer, or distributor from whom the product was obtained |
Maintain a MSDS for each hazardous chemical:
- Keep copies of the required MSDSs for each hazardous chemical present in your workplace. These may be kept in any form, including as a part of operating procedures.
- Each MSDS must be in English. You may also keep copies in other languages.
| Note: |
| If you choose not to rely on MSDSs or labels provided by the manufacturer or importer, you must comply with the chemical hazard communication standard for manufacturers, importers, and distributors, WAC 296-62-054. |
| It may be more appropriate to address the hazards of a process rather than individual hazardous chemicals. MSDSs can be designed to cover groups of hazardous chemicals in a work area. |
[]
Reviser's note: The section above appears as filed by the agency pursuant to RCW 34.08.040; however, the reference to WAC 296-370-55015 is probably intended to be WAC
296-307-55015.
NEW SECTION
WAC 296-307-55020
Make sure material safety data sheets are
readily accessible to your employees.
You must:
Make sure that MSDSs are readily accessible, easily obtained without delay during each work shift to employees when they are in their work area(s).
Make sure that employees, who must travel between workplaces during a work shift, such as when their work is carried out at more than one geographical location, can immediately obtain the required MSDS information in an emergency. (MSDSs may be kept at a central location at the primary workplace facility and accessed by means such as voice communication or laptop computer.)
| Note: |
| Electronic access (such as computer or fax), microfiche, and other alternatives to maintaining paper copies of the MSDSs are permitted as long as they do not create barriers to immediate employee access in each workplace. |
| Barriers to immediate access of electronic MSDSs may include: |
| Power outages |
| Equipment failure |
| System delays |
| Deficient user knowledge to operate equipment |
| Location of equipment outside the work area | |
| Solutions to eliminating these and other possible barriers to access may require the availability of back-up systems, employee training, and providing access equipment in the work areas. |
[]
| EXEMPTIONS: | The following is a summary of items that are exempt from this rule. For complete information about each of these, see WAC 296-307-55055. |
| Pesticides, when labeled as required by the Environmental Protection Agency (EPA) | |
| Food, food additives, color additives, drugs, cosmetics, or medical/veterinary devices or products | |
| Alcoholic beverages not intended for industrial use | |
| Consumer products labeled, as required, by the Consumer Product Safety Commission | |
| Agriculture or vegetable seeds treated and labeled as required by the Federal Seed Act |
| Note: | You are not required to label portable containers into which hazardous chemicals are transferred from labeled containers, if the chemical is used and controlled by the employee who performed the transfer within the same shift. |
Make sure that each container of hazardous chemicals in the workplace is labeled, tagged, or marked with the following information:
The identity of the hazardous chemical(s) using either the chemical or common name
| Note: | You are not required to list each component in a hazardous mixture on the label. If a mixture is referred to on a material safety data sheet (MSDS) by a product name, then the product name should be used as the identifier. |
| Name of Chemical |
| Physical Hazards |
| Health Hazards; |
| Health effects information |
| Affected Target Organs |
⧫ Signs
⧫ Placards
⧫ Process sheets
⧫ Batch tickets
⧫ Operating procedures or
⧫ Other such written materials, as long as the alternate method identifies the containers and conveys the required label information.
| Note: |
| You may use words, pictures, symbols or any combination to communicate the hazards of the chemical. Be sure to train your employees so they can demonstrate a knowledge of the labeling system you use. |
| Place illustration here. |
| Some alternative labeling systems do not communicate target organ information, so the employee will have to rely on training provided by the employer to obtain this information. |
Not remove or deface existing labels on incoming containers of hazardous chemicals (such as those marked with United States Department of Transportation (USDOT) markings, placards, and labels), unless the container is immediately labeled with the required information. You do not need to put on new labels if existing labels already provide the required information. If the package or container is sufficiently cleaned of residue and purged of vapors to remove any potential health or physical hazard, existing labels can be removed.
Make sure that labels or other forms of warning are legible, in English, and prominently displayed on the container, or readily available in the work area throughout each work shift.
| Note: |
| Employers with non-English speaking employees may use other languages in the warning information in addition to the English language. |
| Place illustration here. |
| Above is an example of a labeled container. You may use a laminated or coated label, affixed to the container with a wire, to avoid deterioration of labels due to a solvent, such as acetone. |
Make sure if the hazardous chemical is regulated by WISHA or OSHA in a substance-specific health rule, that the labels or other warnings are used according to those rules.

| Note: | The employer chemical hazard communication information and training requirements also apply to pesticides. Employers who have employees who are exposed to pesticides must be in compliance with this rule and the worker protection standards, WAC 296-307-12040. |
Provide employees with effective information on hazardous chemicals in their work area at the time of their initial job assignment. Whenever a new physical or health hazard related to chemical exposure is introduced into their employees' work areas, information must be provided.
Inform employees of:
⧫ The requirements of this rule.
⧫ Any operations in their work area where hazardous chemicals are present.
⧫ The location and availability of your written Chemical Hazard Communication Program, including the list(s) of hazardous chemicals and material safety data sheets (MSDSs) required by this rule.
Provide employees with effective training about hazardous chemicals in their work area at the time of their initial job assignment. Whenever a new physical or health hazard related to chemical exposure is introduced, the employees must be trained. Make sure that employee training includes:
Methods and observations that may be used to detect the presence or release of a hazardous chemical in the work area. Examples of these methods and observations may include:
⧫ Monitoring conducted by you
⧫ Continuous monitoring devices
⧫ Visual appearance or odor of hazardous chemicals when being released
⧫ Physical and health hazards of the chemicals in the work area, including the likely physical symptoms or effects of overexposure
⧫ Steps employees can take to protect themselves from the chemical hazards in your workplace, including specific procedures implemented by you to protect employees from exposure to hazardous chemicals. Specific procedures may include:
&sqbul; Appropriate work practices
&sqbul; Engineering controls
&sqbul; Emergency procedures
&sqbul; Personal protective equipment to be used
&sqbul; Details of the Chemical Hazard Communication Program developed by you, including an explanation of the labeling system and the MSDS, and how employees can obtain and use the appropriate hazard information.
Tailor information and training to the types of hazards to which employees will be exposed. The information and training may be designed to cover categories of hazards, such as flammability or cancer-causing potential, or it may address specific chemicals. Chemical-specific information must always be available through labels and MSDSs.
Make reasonable efforts to post notices in your employees' native languages (as provided by the department) if those employees have trouble communicating in English.
| Note: |
| Interactive computer-based training or training videos can be used provided they are effective. |
| Your MSDSs may not have WISHA permissible exposure limits (PELs) listed. In some cases, WISHA PELs are stricter than the OSHA PELs and other exposure limits listed on the MSDSs you receive. If this is the case, you must refer to the WISHA PEL table, WAC 296-62-075, for the appropriate exposure limits to be covered during training. |

The species of all other groups may be substituted for those of Group 3 when used in sizes that provide at least equivalent strength. (See Table D-5 for suggested methods of size adjustment.)
(b) All minimum dimensions and specifications set forth in
the following "factor for increase in" for rungs and cleats are
based on the species of wood listed in Group 1 in Table D-5. The
cross-sectional dimensions specified for Group 1 species are
increased by the factors shown in this subsection (based on the
percentages of Table D-5) for the species group of which the
cleats are to be made.

CLASSIFICATION OF VARIOUS SPECIES OF WOOD ACCEPTABLE FOR USE IN LADDER
The species are listed alphabetically within each group. The position of any species within a group therefore bears no relation to its strength or acceptability.
Where ladders are desired for use under conditions favorable to decay, it is recommended that the heartwood of decay-resistant species be used, or that the wood be given a treatment with a wood preservative. The species having the most durable heartwood are marked with an asterisk (*), and these should be preferred where resistance to decay is required.
The allowable fiber stress in bending for the species listed
herein when used for side rails shall not exceed two thousand one
hundred fifty pounds per square inch. These species may be
substituted for Group 3 woods on the following basis: The
dimensions may be not more than ten percent smaller for each
cross-section dimension, or the thickness may remain unchanged,
in which case the width may not be more than fifteen percent
smaller if used edgewise (as in a rail) or twenty-five percent
smaller if used flatwise (as in a tread).

(b) Metal bearings of locks, wheels, pulleys, etc., shall be frequently lubricated.
(c) Frayed or badly worn rope shall be replaced.
(d) Safety feet and other auxiliary equipment shall be kept in good condition to insure proper performance.
(e) Ladders should be stored in such a manner as to provide ease of access or inspection, and to prevent danger of accident when withdrawing a ladder for use.
(f) Wood ladders, when not in use, should be stored at a location where they will not be exposed to the elements, but where there is good ventilation. They shall not be stored near radiators, stoves, steam pipes, or other places subjected to excessive heat or dampness.
(g) Ladders stored in a horizontal position should be supported at a sufficient number of points to avoid sagging and permanent set.
(h) Ladders carried on vehicles should be adequately supported to avoid sagging and securely fastened in position to minimize chafing and the effects of road shocks.
(i) Ladders should be kept coated with a suitable protective material. The painting of ladders is satisfactory providing the ladders are carefully inspected prior to painting by competent and experienced inspectors acting for, and responsible to, the purchaser, and providing the ladders are not for resale.
(j) Ladders shall be inspected frequently and those which have developed defects shall be withdrawn from service for repair or destruction and tagged or marked as "dangerous, do not use."
(k) Rungs should be kept free of grease and oil.
(2) Use. The following safety precautions shall be observed in connection with the use of ladders:
(a) Portable rung and cleat ladders shall, where possible, be used at such a pitch that the horizontal distance from the top support to the foot of the ladder is one-quarter of the working length of the ladder (the length along the ladder between the foot and the top support). The ladder shall be so placed as to prevent slipping, or it shall be lashed, or held in position. Ladders shall not be used in a horizontal position as platforms, runways, or scaffolds.
(b) Ladders for which dimensions are specified should not be used by more than one person at a time nor with ladder jacks and scaffold planks where use by more than one person is anticipated. In such cases, specially designed ladders with larger dimensions of the parts should be procured.
(c) Portable ladders shall be so placed that the side rails have a secure footing. The top rest for portable rung and cleat ladders shall be reasonably rigid and shall have ample strength to support the applied load.
(d) Ladders shall not be placed in front of doors opening toward the ladder unless the door is blocked open, locked, or guarded.
(e) Ladders shall not be placed on boxes, barrels, or other unstable bases to obtain additional height.
(f) To support the top of the ladder at a window opening, a board should be attached across the back of the ladder, extending across the window and providing firm support against the building walls or window frames.
(g) When ascending or descending, the user should face the ladder.
(h) Ladders with broken or missing steps, rungs, or cleats, broken side rails, or other faulty equipment shall not be used; improvised repairs shall not be made.
(i) Short ladders shall not be spliced together to provide long sections.
(j) Ladders made by fastening cleats across a single rail shall not be used.
(k) Ladders shall not be used as guys, braces, or skids, or for other than their intended purposes.
(l) Tops of the ordinary types of stepladders shall not be used as steps.
(m) On two-section extension ladders the minimum overlap for the two sections in use shall be as follows:
| Size of ladder (feet): |
Overlap (feet) |
| Up to and including 36 . . . . . . . . . . . . | 3 |
| Over 36 up to and including 48 . . . . . . . . . . . . | 4 |
| Over 48 up to and including 60 . . . . . . . . . . . . | 5 |
(o) No ladder should be used to gain access to a roof unless the top of the ladder shall extend at least three feet above the point of support, at eave, gutter, or roof line.
(p) Adjustment of extension ladders should only be made by the user when standing at the base of the ladder, so that the user may observe when the locks are properly engaged. Adjustment of extension ladders from the top of the ladder (or any level over the locking device) is a dangerous practice and should not be attempted. Adjustment should not be made while the user is standing on the ladder.
(q) Middle and top sections of sectional or window cleaner's ladders should not be used for bottom section unless the user equips them with safety shoes.
(r) Extension ladders should always be erected so that the upper section is resting on the bottom section.
(s) The user should equip all portable rung ladders with nonslip bases when there is a hazard of slipping. Nonslip bases are not intended as a substitute for care in safety placing, lashing, or holding a ladder that is being used upon oily metal, concrete, or slippery surfaces.
(t) The bracing on the back legs of step ladders is designed solely for increasing stability and not for climbing.
(u) When service conditions warrant, hooks may be attached at or near the top of portable ladders to give added security.
(v) Stepladders shall not be used as single ladders.
(w) Separate ladders for ascending and descending shall be provided in building construction of more than two stories in height, or where traffic is heavy.
(x) Where one broad ladder is used, a center rail shall be provided, and each side plainly marked "up" and "down."
(y) Ladder rungs shall not be used to support more than one section of plank, and not more than two persons shall work on such section of planking at one and the same time. When two persons are working on the same section of plank, their work should be so arranged that their weight is equally distributed between two ladders as nearly as possible.
(z) When ladders are used of a length sufficient to possess a tendency to spring when weight is applied, they shall be provided with bracing to overcome same. This applies particularly to extension ladders.
(aa) Before climbing ladders, workers shall see that their shoes are free and clean of greasy or slippery substances.
(bb) When working from a stepladder over five feet high a worker shall not stand on a step higher than the third step from the top of the stepladder.
(cc) Ladders shall not be placed or used in elevator shafts or hoistways except where used by workers engaged in work within such shafts or hoistways, and then they shall be protected from objects falling from operations at higher elevations in or adjoining the shaft.
(dd) Workers shall not ascend or descend ladders while carrying tools or materials which will interfere with the free use of both hands.
(ee))) Ladders shall pass the following test:
When tested as a simple beam with a support under each end and the center rung loaded with a two hundred pound load, the ladder must support this load for ten minutes without permanent set and without showing any sign of failure. The maximum deflection shall not be greater than shown in the enclosed table.

(2) Foreword.
(a) As guidance for each employer's development of an appropriate laboratory chemical hygiene plan, the following nonmandatory recommendations are provided. They were extracted from "Prudent Practices for Handling Hazardous Chemicals in Laboratories" (referred to below as "Prudent Practices"), which was published in 1981 by the National Research Council and is available from the National Academy Press, 2101 Constitution Ave., N.W., Washington DC 20418.
(b) "Prudent practices" is cited because of its wide distribution and acceptance and because of its preparation by members of the laboratory community through the sponsorship of the National Research Council. However, none of the recommendations given here will modify any requirements of the laboratory standard. This appendix merely presents pertinent recommendations from "prudent practices," organized into a form convenient for quick reference during operation of a laboratory facility and during development and application of a chemical hygiene plan. Users of this appendix should consult "prudent practices" for a more extended presentation and justification for each recommendation.
(c) "Prudent practices" deals with both safety and chemical hazards while the laboratory standard is concerned primarily with chemical hazards. Therefore, only those recommendations directed primarily toward control of toxic exposures are cited in this appendix, with the term "chemical hygiene" being substituted for the word "safety." However, since conditions producing or threatening physical injury often pose toxic risks as well, page references concerning major categories of safety hazards in the laboratory are given in section F.
(d) The recommendations from "prudent practices" have been paraphrased, combined, or otherwise reorganized, and headings have been added. However, their sense has not been changed.
(e) Corresponding sections of the standard and this appendix.
(f) The following table is given for the convenience of those who are developing a chemical hygiene plan which will satisfy the requirements of WAC 296-62-40009. It indicates those sections of this appendix which are most pertinent to each of the sections of WAC 296-62-40009 and related sections.

(a) General principles for work with laboratory chemicals in addition to the more detailed recommendations listed below in sections (b) through (e), "prudent practices" expresses certain general principles, including the following:
(i) It is prudent to minimize all chemical exposures. Because few laboratory chemicals are without hazards, general precautions for handling all laboratory chemicals should be adopted, rather than specific guidelines for particular chemicals (2, 10). Skin contact with chemicals should be avoided as a cardinal rule (198).
(ii) Avoid underestimation of risk. Even for substances of no known significant hazard, exposure should be minimized; for work with substances which present special hazards, special precautions should be taken (10, 37, 38). One should assume that any mixture will be more toxic than its most toxic component (30, 103) and that all substances of unknown toxicity are toxic (3, 34).
(iii) Provide adequate ventilation. The best way to prevent exposure to airborne substances is to prevent their escape into the working atmosphere by use of hoods and other ventilation devices (32, 198).
(iv) Institute a chemical hygiene program. A mandatory chemical hygiene program designed to minimize exposures is needed; it should be a regular, continuing effort, not merely a standby or short-term activity (6, 11). Its recommendations should be followed in academic teaching laboratories as well as by full-time laboratory workers (13).
(v) Observe the PELs, TLVs. The permissible exposure limits of WISHA and the threshold limit values of the American Conference of Governmental Industrial Hygienists should not be exceeded (13).
(b) Chemical hygiene responsibilities. Responsibility for chemical hygiene rests at all levels (6, 11, 21) including the:
(i) Chief executive officer, who has ultimate responsibility for chemical hygiene within the institution and must, with other administrators, provide continuing support for institutional chemical hygiene (7, 11).
(ii) Supervisor of the department or other administrative unit, who is responsible for chemical hygiene in that unit (7).
(iii) Chemical hygiene officer(s), whose appointment is essential (7) and who must:
(A) Work with administrators and other employees to develop and implement appropriate chemical hygiene policies and practices (7);
(B) Monitor procurement, use, and disposal of chemicals used in the lab (8);
(C) See that appropriate audits are maintained (8);
(D) Help project directors develop precautions and adequate facilities (10);
(E) Know the current legal requirements concerning regulated substances (50); and
(F) Seek ways to improve the chemical hygiene program (8, 11).
(iv) Laboratory supervisor, who has overall responsibility for chemical hygiene in the laboratory (21) including responsibility to:
(A) Ensure that workers know and follow the chemical hygiene rules, that protective equipment is available and in working order, and that appropriate training has been provided (21, 22);
(B) Provide regular, formal chemical hygiene and housekeeping inspections including routine inspections of emergency equipment (21, 171);
(C) Know the current legal requirements concerning regulated substances (50, 231);
(D) Determine the required levels of protective apparel and equipment (156, 160, 162); and
(E) Ensure that facilities and training for use of any material being ordered are adequate (215).
(v) Project director or director of other specific operation, who has primary responsibility for chemical hygiene procedures for that operation (7).
(vi) Laboratory worker, who is responsible for:
(A) Planning and conducting each operation in accordance with the institutional chemical hygiene procedures (7, 21, 22, 230); and
(B) Developing good personal chemical hygiene habits (22).
(c) The laboratory facility:
(i) Design. The laboratory facility should have:
(A) An appropriate general ventilation system (see C4 below) with air intakes and exhausts located so as to avoid intake of contaminated air (194);
(B) Adequate, well-ventilated stockrooms/storerooms (218, 219);
(C) Laboratory hoods and sinks (12, 162);
(D) Other safety equipment including eyewash fountains and drench showers (162, 169); and
(E) Arrangements for waste disposal (12, 240).
(ii) Maintenance. Chemical-hygiene-related equipment (hoods, incinerator, etc.) should undergo continuing appraisal and be modified if inadequate (11, 12).
(iii) Usage. The work conducted (10) and its scale (12) must be appropriate to the physical facilities available and, especially, to the quality of ventilation (13).
(iv) Ventilation.
(A) General laboratory ventilation. This system should: Provide a source of air for breathing and for input to local ventilation devices (199); it should not be relied on for protection from toxic substances released into the laboratory (198); ensure that laboratory air is continually replaced, preventing increase of air concentrations of toxic substances during the working day (194); direct air flow into the laboratory from nonlaboratory areas and out to the exterior of the building (194).
(B) Hoods. A laboratory hood with 2.5 linear feet of hood space per person should be provided for every 2 workers if they spend most of their time working with chemicals (199); each hood should have a continuous monitoring device to allow convenient confirmation of adequate hood performance before use (200, 209). If this is not possible, work with substances of unknown toxicity should be avoided (13) or other types of local ventilation devices should be provided (199). (See pp. 201-206 for a discussion of hood design, construction, and evaluation.)
(C) Other local ventilation devices. Ventilated storage cabinets, canopy hoods, snorkels, etc., should be provided as needed (199). Each canopy hood and snorkel should have a separate exhaust duct (207).
(D) Special ventilation areas. Exhaust air from glove boxes and isolation rooms should be passed through scrubbers or other treatment before release into the regular exhaust system (208). Cold rooms and warm rooms should have provisions for rapid escape and for escape in the event of electrical failure (209).
(E) Modifications. Any alteration of the ventilation system should be made only if thorough testing indicates that worker protection from airborne toxic substances will continue to be adequate (12, 193, 204).
(F) Performance. Rate: 4-12 room air changes/hour is normally adequate general ventilation if local exhaust systems such as hoods are used as the primary method of control (194).
(G) Quality. General air flow should not be turbulent and should be relatively uniform throughout the laboratory, with no high velocity or static areas (194, 195); airflow into and within the hood should not be excessively turbulent (200); hood face velocity should be adequate (typically 60-100 lfm) (200, 204).
(H) Evaluation. Quality and quantity of ventilation should be evaluated on installation (202), regularly monitored (at least every 3 months) (6, 12, 14, 195), and reevaluated whenever a change in local ventilation devices is made (12, 195, 207). See pp. 195-198 for methods of evaluation and for calculation of estimated airborne contaminant concentrations.
(d) Components of the chemical hygiene plan:
(i) Basic rules and procedures (recommendations for these are given in section (e), below).
(ii) Chemical procurement, distribution, and storage.
(A) Procurement. Before a substance is received, information on proper handling, storage, and disposal should be known to those who will be involved (215, 216). No container should be accepted without an adequate identifying label (216). Preferably, all substances should be received in a central location (216).
(B) Stockrooms/storerooms. Toxic substances should be segregated in a well-identified area with local exhaust ventilation (221). Chemicals which are highly toxic (227) or other chemicals whose containers have been opened should be in unbreakable secondary containers (219). Stored chemicals should be examined periodically (at least annually) for replacement, deterioration, and container integrity (218-19).
(C) Stockrooms/storerooms should not be used as preparation or repackaging areas, should be open during normal working hours, and should be controlled by one person (219).
(D) Distribution. When chemicals are hand carried, the container should be placed in an outside container or bucket. Freight-only elevators should be used if possible (223).
(E) Laboratory storage. Amounts permitted should be as small as practical. Storage on bench tops and in hoods is inadvisable. Exposure to heat or direct sunlight should be avoided. Periodic inventories should be conducted, with unneeded items being discarded or returned to the storeroom/stockroom (225-6, 229).
(iii) Environmental monitoring. Regular instrumental monitoring of airborne concentrations is not usually justified or practical in laboratories but may be appropriate when testing or redesigning hoods or other ventilation devices (12) or when a highly toxic substance is stored or used regularly (e.g., 3 times/week) (13).
(iv) Housekeeping, maintenance, and inspections.
(A) Cleaning. Floors should be cleaned regularly (24).
(B) Inspections. Formal housekeeping and chemical hygiene inspections should be held at least quarterly (6, 21) for units which have frequent personnel changes and semiannually for others; informal inspections should be continual (21).
(C) Maintenance. Eye wash fountains should be inspected at intervals of not less than 3 months (6). Respirators for routine use should be inspected periodically by the laboratory supervisor (169). Safety showers should be tested routinely (169). Other safety equipment should be inspected regularly. (E.g., every 3-6 months) (6, 24, 171). Procedures to prevent restarting of out-of-service equipment should be established (25).
(D) Passageways. Stairways and hallways should not be used as storage areas (24). Access to exits, emergency equipment, and utility controls should never be blocked (24).
(v) Medical program.
(A) Compliance with regulations. Regular medical surveillance should be established to the extent required by regulations (12).
(B) Routine surveillance. Anyone whose work involves regular and frequent handling of toxicologically significant quantities of a chemical should consult a qualified physician to determine on an individual basis whether a regular schedule of medical surveillance is desirable (11, 50).
(C) First aid. Personnel trained in first aid should be available during working hours and an emergency room with medical personnel should be nearby (173). See pp. 176-178 for description of some emergency first-aid procedures.
(vi) Protective apparel and equipment. These should include for each laboratory:
(A) Protective apparel compatible with the required degree of protection for substances being handled (158-161);
(B) An easily accessible drench-type safety shower (162, 169);
(C) An eyewash fountain (162);
(D) A fire extinguisher (162-164);
| Note: | For additional requirements relating to portable fire extinguishers see WAC 296-800-300. |
(F) Other items designated by the laboratory supervisor (156, 160).
(vii) Records.
(A) Accident records should be written and retained (174).
(B) Chemical hygiene plan records should document that the facilities and precautions were compatible with current knowledge and regulations (7).
(C) Inventory and usage records for high-risk substances should be kept as specified in sections E3e below.
(D) Medical records should be retained by the institution in accordance with the requirements of state and federal regulations (12).
(viii) Signs and labels. Prominent signs and labels of the following types should be posted:
(A) Emergency telephone numbers of emergency personnel/facilities, supervisors, and laboratory workers (28);
(B) Identity labels, showing contents of containers (including waste receptacles) and associated hazards (27, 48);
(C) Location signs for safety showers, eyewash stations, other safety and first aid equipment, exits (27) and areas where food and beverage consumption and storage are permitted (24); and
(D) Warnings at areas or equipment where special or unusual hazards exist (27).
(ix) Spills and accidents.
(A) A written emergency plan should be established and communicated to all personnel; it should include procedures for ventilation failure (200), evacuation, medical care, reporting, and drills (172).
(B) There should be an alarm system to alert people in all parts of the facility including isolation areas such as cold rooms (172).
(C) A spill control policy should be developed and should include consideration of prevention, containment, cleanup, and reporting (175).
(D) All accidents or near accidents should be carefully analyzed with the results distributed to all who might benefit (8, 28).
(x) Information and training program.
(A) Aim: To assure that all individuals at risk are adequately informed about the work in the laboratory, its risks, and what to do if an accident occurs (5, 15).
(B) Emergency and personal protection training: Every laboratory worker should know the location and proper use of available protective apparel and equipment (154, 169).
(C) Some of the full-time personnel of the laboratory should be trained in the proper use of emergency equipment and procedures (6).
(D) Such training as well as first-aid instruction should be available to (154) and encouraged for (176) everyone who might need it.
(E) Receiving and stockroom/storeroom personnel should know about hazards, handling equipment, protective apparel, and relevant regulations (217).
(F) Frequency of training: The training and education program should be a regular, continuing activity -- not simply an annual presentation (15).
(G) Literature/consultation: Literature and consulting advice concerning chemical hygiene should be readily available to laboratory personnel, who should be encouraged to use these information resources (14).
(xi) Waste disposal program.
(A) Aim: To assure that minimal harm to people, other organisms, and the environment will result from the disposal of waste laboratory chemicals (5).
(B) Content (14, 232, 233, 240): The waste disposal program should specify how waste is to be collected, segregated, stored, and transported and include consideration of what materials can be incinerated. Transport from the institution must be in accordance with DOT regulations (244).
(C) Discarding chemical stocks: Unlabeled containers of chemicals and solutions should undergo prompt disposal; if partially used, they should not be opened (24, 27).
(D) Before a worker's employment in the laboratory ends, chemicals for which that person was responsible should be discarded or returned to storage (226).
(E) Frequency of disposal: Waste should be removed from laboratories to a central waste storage area at least once per week and from the central waste storage area at regular intervals (14).
(F) Method of disposal: Incineration in an environmentally acceptable manner is the most practical disposal method for combustible laboratory waste (14, 238, 241).
(G) Indiscriminate disposal by pouring waste chemicals down the drain (14, 231, 242) or adding them to mixed refuse for landfill burial is unacceptable (14).
(H) Hoods should not be used as a means of disposal for volatile chemicals (40, 200).
(I) Disposal by recycling (233, 243) or chemical decontamination (40, 230) should be used when possible.
(e) Basic rules and procedures for working with chemicals. The chemical hygiene plan should require that laboratory workers know and follow its rules and procedures. In addition to the procedures of the subprograms mentioned above, these should include the general rules following:
(i) General rules. The following should be used for essentially all laboratory work with chemicals:
(A) Accidents and spills -- Eye contact: Promptly flush eyes with water for a prolonged period (15 minutes) and seek medical attention (33, 172).
(B) Ingestion: Encourage the victim to drink large amounts of water (178).
(C) Skin contact: Promptly flush the affected area with water (33, 172, 178) and remove any contaminated clothing (172, 178). If symptoms persist after washing, seek medical attention (33).
(D) Clean-up. Promptly clean up spills, using appropriate protective apparel and equipment and proper disposal (24, 33). See pp. 233-237 for specific clean-up recommendations.
(E) Avoidance of "routine" exposure: Develop and encourage safe habits (23); avoid unnecessary exposure to chemicals by any route (23);
(F) Do not smell or taste chemicals (32). Vent apparatus which may discharge toxic chemicals (vacuum pumps, distillation columns, etc.) into local exhaust devices (199).
(G) Inspect gloves (157) and test glove boxes (208) before use.
(H) Do not allow release of toxic substances in cold rooms and warm rooms, since these have contained recirculated atmospheres (209).
(I) Choice of chemicals: Use only those chemicals for which the quality of the available ventilation system is appropriate (13).
(J) Eating, smoking, etc.: Avoid eating, drinking, smoking, gum chewing, or application of cosmetics in areas where laboratory chemicals are present (22, 24, 32, 40); wash hands before conducting these activities (23, 24).
(K) Avoid storage, handling, or consumption of food or beverages in storage areas, refrigerators, glassware, or utensils which are also used for laboratory operations (23, 24, 226).
(L) Equipment and glassware: Handle and store laboratory glassware with care to avoid damage; do not use damaged glassware (25). Use extra care with Dewar flasks and other evacuated glass apparatus; shield or wrap them to contain chemicals and fragments should implosion occur (25). Use equipment only for its designed purpose (23, 26).
(M) Exiting: Wash areas of exposed skin well before leaving the laboratory (23).
(N) Horseplay: Avoid practical jokes or other behavior which might confuse, startle, or distract another worker (23).
(O) Mouth suction: Do not use mouth suction for pipeting or starting a siphon (23, 32).
(P) Personal apparel: Confine long hair and loose clothing (23, 158). Wear shoes at all times in the laboratory but do not wear sandals, perforated shoes, or sneakers (158).
(Q) Personal housekeeping: Keep the work area clean and uncluttered, with chemicals and equipment being properly labeled and stored; clean up the work area on completion of an operation or at the end of each day (24).
(R) Personal protection: Assure that appropriate eye protection (154-156) is worn by all persons, including visitors, where chemicals are stored or handled (22, 23, 33, 154).
(S) Wear appropriate gloves when the potential for contact with toxic materials exists (157); inspect the gloves before each use, wash them before removal, and replace them periodically (157). (A table of resistance to chemicals of common glove materials is given p. 159.)
(T) Use appropriate (164-168) respiratory equipment when air contaminant concentrations are not sufficiently restricted by engineering controls (164-5), inspecting the respirator before use (169).
(U) Use any other protective and emergency apparel and equipment as appropriate (22, 157-162).
(V) Void use of contact lenses in the laboratory unless necessary; if they are used, inform supervisor so special precautions can be taken (155).
(W) Remove laboratory coats immediately on significant contamination (161).
(X) Planning: Seek information and advice about hazards (7), plan appropriate protective procedures, and plan positioning of equipment before beginning any new operation (22, 23).
(Y) Unattended operations: Leave lights on, place an appropriate sign on the door, and provide for containment of toxic substances in the event of failure of a utility service (such as cooling water) to an unattended operation (27, 128).
(Z) Use of hood: Use the hood for operations which might result in release of toxic chemical vapors or dust (198-9).
(AA) As a rule of thumb, use a hood or other local ventilation device when working with any appreciably volatile substance with a TLV of less than 50 ppm (13).
(BB) Confirm adequate hood performance before use; keep hood closed at all times except when adjustments within the hood are being made (200); keep materials stored in hoods to a minimum and do not allow them to block vents or air flow (200).
(CC) Leave the hood "on" when it is not in active use if toxic substances are stored in it or if it is uncertain whether adequate general laboratory ventilation will be maintained when it is "off" (200).
(DD) Vigilance: Be alert to unsafe conditions and see that they are corrected when detected (22).
(EE) Waste disposal: Assure that the plan for each laboratory operation includes plans and training for waste disposal (230).
(FF) Deposit chemical waste in appropriately labeled receptacles and follow all other waste disposal procedures of the chemical hygiene plan (22, 24).
(GG) Do not discharge to the sewer concentrated acids or bases (231); highly toxic, malodorous, or lachrymatory substances (231); or any substances which might interfere with the biological activity of waste water treatment plants, create fire or explosion hazards, cause structural damage, or obstruct flow (242).
(HH) Working alone: Avoid working alone in a building; do not work alone in a laboratory if the procedures being conducted are hazardous (28).
(ii) Working with allergens and embryotoxins.
(A) Allergens (examples: Diazomethane, isocyanates, bichromates): Wear suitable gloves to prevent hand contact with allergens or substances of unknown allergenic activity (35).
(B) Embryotoxins (34-5) (examples: Organomercurials, lead compounds, formamide): Women of childbearing age shall handle these substances only in a hood whose satisfactory performance has been confirmed, using appropriate protective apparel (especially gloves) to prevent skin contact.
(C) Review each use of these materials with the research supervisor and review continuing uses annually or whenever a procedural change is made.
(D) Store these substances, properly labeled, in an adequately ventilated area in an unbreakable secondary container.
(E) Notify supervisors of all incidents of exposure or spills; consult a qualified physician when appropriate.
(iii) Work with chemicals of moderate chronic or high acute toxicity.
Examples: diisopropylflurophosphate (41), hydrofluoric acid (43), hydrogen cyanide (45).
(iv) Supplemental rules to be followed in addition to those mentioned above (Procedure B of "prudent practices," pp. 39-41):
(A) Aim: To minimize exposure to these toxic substances by any route using all reasonable precautions (39).
(B) Applicability: These precautions are appropriate for substances with moderate chronic or high acute toxicity used in significant quantities (39).
(C) Location: Use and store these substances only in areas of restricted access with special warning signs (40, 229).
(D) Always use a hood (previously evaluated to confirm adequate performance with a face velocity of at least 60 linear feet per minute) (40) or other containment device for procedures which may result in the generation of aerosols or vapors containing the substance (39); trap released vapors to prevent their discharge with the hood exhaust (40).
(E) Personal protection: Always avoid skin contact by use of gloves and long sleeves (and other protective apparel as appropriate) (39). Always wash hands and arms immediately after working with these materials (40).
(F) Records: Maintain records of the amounts of these materials on hand, amounts used, and the names of the workers involved (40, 229).
(G) Prevention of spills and accidents: Be prepared for accidents and spills (41).
(H) Assure that at least 2 people are present at all times if a compound in use is highly toxic or of unknown toxicity (39).
(I) Store breakable containers of these substances in chemically resistant trays; also work and mount apparatus above such trays or cover work and storage surfaces with removable, absorbent, plastic backed paper (40).
(J) If a major spill occurs outside the hood, evacuate the area; assure that cleanup personnel wear suitable protective apparel and equipment (41).
(K) Waste: Thoroughly decontaminate or incinerate contaminated clothing or shoes (41). If possible, chemically decontaminate by chemical conversion (40).
(L) Store contaminated waste in closed, suitably labeled, impervious containers (for liquids, in glass or plastic bottles half-filled with vermiculite) (40).
(v) Work with chemicals of high chronic toxicity.
Examples: Dimethylmercury and nickel carbonyl (48), benzo-a-pyrene (51), N-nitrosodiethylamine (54), other human carcinogens or substances with high carcinogenic potency in animals (38).
(vi) Further supplemental rules to be followed, in addition to all these mentioned above, for work with substances of known high chronic toxicity (in quantities above a few milligrams to a few grams, depending on the substance) (47). (Procedure A of "Prudent Practices" pp. 47-50).
(A) Access: Conduct all transfers and work with these substances in a "controlled area": A restricted access hood, glove box, or portion of a lab, designated for use of highly toxic substances, for which all people with access are aware of the substances being used and necessary precautions (48).
(B) Approvals: Prepare a plan for use and disposal of these materials and obtain the approval of the laboratory supervisor (48).
(C) Noncontamination/decontamination: Protect vacuum pumps against contamination by scrubbers or HEPA filters and vent them into the hood (49). Decontaminate vacuum pumps or other contaminated equipment, including glassware, in the hood before removing them from the controlled area (49, 50).
(D) Decontaminate the controlled area before normal work is resumed there (50).
(E) Ex
