Section 296-307-56010. Conduct complete hazard evaluations.

IMPORTANT:

• Hazard evaluation is a process where hazards of chemicals are identified by reviewing available research or testing information. You are not required to perform your own laboratory research or testing to meet the requirements of this section

– Information from hazard evaluations is used to complete material safety data sheets (MSDSs) and labels

– MSDSs from your suppliers may be used to complete the hazard evaluation for chemicals you produce

– MSDSs and labels are NOT required for chemicals that are determined to be nonhazardous

• Importers and manufacturers are required to develop MSDSs and labels. If you decide to develop your own MSDSs and labels, then this chapter also applies to you.

You must:

(1) Describe in writing your procedures for conducting hazard evaluations.

(2) Conduct a complete hazard evaluation for ALL chemicals you produce or import to determine if they are hazardous chemicals.

• Identify and consider available scientific evidence of health and physical hazards

• Evidence that meets the criteria in Table 3 must be used to establish a hazard

• Chemicals identified in a Table 4 source must be regarded as hazardous

• The scope of health hazards considered must include the categories in Tables 5 and 6

• If the chemical is a mixture, follow the additional criteria in Table 7

• If you find evidence that meets the criteria in Table 3, use it in your hazard evaluation.

1	If human data is not available, use results of tests done on animals and other available studies to predict health effects on employees (for example, effects resulting from short and long-term exposures to chemicals).
2	In vitro studies alone do not generally form the basis of a finding of hazard.
3	These terms are defined in WAC 296-307-56050.

Chemicals identified in the sources listed in Table 4 must be assumed to be hazardous (including carcinogens and potential carcinogens).

Chemicals meeting Table 5 definitions, along with the criteria for established evidence in Table 3, must be regarded as hazardous.

Table 5 is NOT intended to present all hazard categories or test methods. Available scientific data involving other test methods and animal species must also be evaluated to determine a chemical's hazards.

Categories provided in Table 6 illustrate the broad range of target organ effects that must be considered when conducting hazard evaluations. Chemicals meeting Table 6 definitions, along with the criteria for established evidence in Table 3, must be regarded as hazardous.

Examples provided in Table 6 are NOT intended to be a complete list.
