WAC 296-828-100. Scope

This chapter applies to the laboratory use of hazardous chemicals. To determine if this chapter applies to your workplace, use Table 1. Important: 1. When your laboratory operation is covered by this chapter, and you use any of the substances in Table 2, the following applies with the exception of formaldehyde use in histology, pathology, and anatomy laboratories. In histology, pathology, and anatomy laboratories you must follow the requirements in chapter 296-856 WAC, Formaldehyde. This chapter applies to all other formaldehyde laboratory uses as defined in Table 1: a. The exposure limits and any requirement protecting employees from skin and eye contact in the rules listed in Table 2 will still apply. b. Where the action level (or where no action level exists, the permissible exposure limit) is exceeded for a substance listed in Table 2, the exposure evaluation and medical surveillance requirements in the substance rule will still apply. c. You are not required to meet other requirements of the substance rule. 2. To get the permissible exposure limits (PELs) for hazardous chemicals used in your laboratory, see chapter 296-841 WAC, Airborne contaminants.
