• PPE and CPC must be selected to be appropriate for the nature, degree, and extent of the hazards wearers may encounter.

Personal protective equipment (PPE) must be selected and used with the intent to protect employees from hazards and potential hazards. In addition, chemical protective clothing (CPC) and chemical protective equipment (such as PPE) used by hazardous materials response (HAZMAT) team members and hazardous materials specialists must meet the requirements contained in subparagraphs (g)(3) to (g)(5) of 1910.120 and 1926.65, which cover PPE selection criteria, protocols for testing totally encapsulating chemical protective suits, and PPE programs.

Refer to the Personal protective equipment and clothing section for more about subparagraphs (g)(3) and (g)(5).

Notes:

• Personnel engaged in emergency response and exposed to hazardous substances that present an inhalation or potential inhalation hazard must comply with paragraph (q)(3)(iv) for respirator selection criteria. Whereas, subparagraphs (g)(3) to (g)(5) refer to other types of PPE and CPC.
• In situations where the type of hazard is fire beyond the incipient stage, or thermal energy, then subparagraph (q)(3)(iii) of 1910.120 or 1926.65 must be followed. When the type of chemical and its concentration are “totally unknown” or “somewhat known,” the appropriate protective clothing and other equipment selected must be based on experience, judgment, and professional knowledge.
• Determining the nature, degree, and extent of the hazards may be done by taking air measurements with monitoring equipment for toxic concentrations of vapors, particulates, explosive potential, and the possibility of radiation exposure. Also, visual observation, existing data (including safety data sheets, or SDSs), and past experience can help determine the potential risks of exposure.
