HAZWOPER for Emergency Responders

Covered employees include first responders, such as HAZMAT team members, fire and rescue personnel, police, and medical personnel who may respond to emergency releases.

Emergency responders can effectively respond to and manage an incident by completing six activities using the acronym "HAZMAT."

Managing the Incident: Implementing the Incident Command System.

Termination: Decontamination, post-incident analysis, medical surveillance.

Incidental and Uncontrolled Releases

The HAZWOPER standard does not apply to "incidental releases" of hazardous substances, which are releases that do not pose a significant safety or health hazard to employees in the immediate vicinity or to the employees cleaning it up.

Incidental Releases

Incidental releases are limited in quantity, exposure potential, or toxicity and present minor safety or health hazards to employees in the immediate work area or those assigned to clean them up. An example is a laboratory pint-size container that does not pose a significant safety and health threat at that volume.

Uncontrolled Releases

In some instances, releases may be "uncontrolled" and require an emergency response depending on the circumstances of the release (e.g., toxicity and volume of the substance, training and experience of employees in the immediate area, availability of response equipment and PPE, etc.). An example is the release of chlorine gas above the IDLH level, obscuring visibility and moving through a facility.
