Section 296-307-56025. Develop or obtain material safety data sheets (MSDSs).

You must:

• Develop or obtain a complete and accurate material safety data sheet (MSDS) for each hazardous chemical or mixture according to ALL of the following:

– ALL information in Table 8 must be completed. If there is no relevant information for a required item, this must be noted. Blank spaces are not permitted.

Note:	• No specific format is required for MSDSs; however, an example format (OSHA form 174) can be found online at: http://www.osha.gov
	• One MSDS can be developed for a group of complex mixtures (for example, jet fuels or crude oil) IF the health and physical hazards of the mixtures are similar (the amounts of chemicals in the mixture may vary).

– Content of MSDSs must accurately represent the available scientific evidence.

Note:	You may report results of scientifically valid studies that tend to refute findings of hazards.

– MSDSs must be in English.

Note:	You may develop copies of MSDSs in other languages.

You must:

• Revise an MSDS when you become aware of new and significant information regarding the hazards of a chemical, or how to protect against the hazards

– Within three months after you first become aware of the information

OR

– Before the chemical is reintroduced into the workplace if the chemical is no longer being used, produced or imported.

1	The identities of some chemicals may be protected as trade secret information (see chapter 296-62 WAC, Part B-1, Trade secrets).
2	WISHA PEL categories are defined, and values are provided, in chapter 296-307 WAC, Part Y-6.
3	A "skin notation" listed with either an ACGIH TLV or WISHA/OSHA PEL indicates that skin absorption is a primary route of exposure.
4	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.
5	Signs and symptoms of exposure to hazardous substances include those that:
	• Can be measured such as decreased pulmonary function
	AND
	• Are subjective such as feeling short of breath.
