Most EMS physicians are well versed in the occupational component of hazardous materials as it pertains to the Occupational Safety and Health Administration (OSHA) regulations that apply to the work environment but may not be fully prepared to respond in support of a hazardous materials incident operation and may not even be familiar with the principles laid out in 29 CFR 1910.120 (Hazardous Waste Operations and Emergency Response: HAZWOPER) or the availability of various publications on the topic provided by OSHA, NIOSH, FEMA, and the EPA. HAZMAT incidents occur in all areas affecting every community (Figure 72-1). This chapter will serve as a primer aimed at the EMS physician as a component of the response to a HAZMAT incident.
