Which regulation mandates the implementation of an incident management system for hazardous materials incidents?

The regulation that mandates the implementation of an incident management system for hazardous materials incidents is OSHA 29 CFR 1910.120, commonly known as the Hazardous Waste Operations and Emergency Response (HAZWOPER) standard. This standard outlines the necessary procedures and protocols for managing hazardous waste operations and emergency response situations, which include incidents involving hazardous materials.

Under this regulation, employers are required to establish an incident management system that ensures the safety of employees and the public during hazardous material incidents. This encompasses training, safety measures, and protocols that need to be followed to effectively manage such situations, thereby minimizing risks and ensuring a coordinated response.

The other options pertain to different aspects of safety regulations. EPA 40 CFR Part 68 focuses on chemical accident prevention provisions; NIOSH 42 CFR Part 84 deals with respiratory protection standards; and DOT 49 CFR Part 171 governs the transport of hazardous materials, but none of these specifically mandate an incident management system for emergencies as outlined in the HAZWOPER standard.
