Note: The identities of some chemicals may be protected as trade secret information (see Chapter 296-62 WAC, Part B-1, Trade Secrets).

• – For a single substance chemical, include the chemical and common name(s) of the substance
• – For mixtures tested as a whole
  • Include the common name(s) of the mixture
    and
  • List the chemical and common name(s) of ingredients that contribute to the known hazards
• – For mixtures NOT tested as a whole, list the chemical and common name(s) of hazardous ingredients
  • That make up 1% or more of the mixture, by weight or volume, including carcinogens (if 0.1% concentration or more, by weight or volume)
• – If ingredients are less than the above concentrations but may present a health risk to employees (for example, allergic reaction or exposure could exceed the permissible exposure limits, or PEL) they must be listed here
• Exposure limits for airborne concentrations. Include ALL of the following, when they exist:
• - WISHA or OSHA PELs
  • The 8-hour time weighted average (TWA)
  • The short-term exposure limit (STEL), if available
  • Ceiling values, if available
    
  Note: WISHA PEL categories are defined, and values are provided, in Chapter 296-841 WAC, Airborne contaminants.
  
• – Threshold limit values (TLVs) including 8-hour TWAs, STELs, and ceiling values
• – Other exposure limits used or recommended by the employer preparing the MSDS

• Physical and chemical characteristics
• – For example, boiling point, vapor pressure, and odor
• Fire, explosion data, and related information
• – For example, flashpoint, flammable and explosion limits, extinguishing media, and unusual fire or explosion hazards
• Physical hazards of the chemical including reactivity information
• – For example, incompatibilities, decomposition products, by-products, and conditions to avoid

• Health hazard information including ALL of the following:
• – Primary routes of exposure
  • For example, inhalation, ingestion, and skin absorption or other contact

Note: A "Skin notation" listed with either an ACGIH TLV or WISHA/OSHA PEL indicates that skin absorption is a primary route of exposure.

• – Health effects (or hazards) associated with:
  • Short-term exposure
    and
  • Long-term exposure
    
    Examples of:
    
• Short-term health effects (or hazards) include eye irritation, skin damage caused by contact with corrosives, narcosis, sensitization, and lethal dose.
• Long-term health effects (or hazards) include cancer, liver degeneration, and silicosis.
  
• – Whether the chemical is listed or described as a carcinogen or potential carcinogen in the latest editions of each of the following:
  • The National Toxicology Program (NTP) Annual Report on Carcinogens
    or
  • The International Agency for Research on Cancer (IARC) Monographs as a potential carcinogen
    or
  • WISHA or OSHA rules

• – Signs and symptoms of exposure to hazardous substances, including those that:
  • Can be measured such as decreased pulmonary function
    and
  • Are subjective such as feeling short of breath.
    
  – Medical conditions generally recognized as being aggravated by exposure

• Generally applicable precautions for safe handling and use known to the employer preparing the MSDS
  
• - For example, appropriate procedures for clean-up of spills and leaks, waste disposal method, precautions during handling and storing

• Generally applicable and appropriate control measures known to the employer preparing the MSDS, including ALL of the following:
• – Engineering controls (for example, general or local exhaust ventilation)
• – Work practices
• – Personal protective equipment (PPE)
• – Personal hygiene practices
• – Protective measures during repair and maintenance of contaminated equipment
