What is the primary action associated with Level 2 HAZWOPER response?

The primary action associated with Level 2 HAZWOPER response is taking defensive action. This level of response typically involves situations where the hazardous materials are contained and preventable steps are taken to protect the environment and human health without engaging directly with the hazardous substance.

Defensive actions can include establishing a safe perimeter, utilizing barriers, and implementing procedures to mitigate any potential spread of contaminants. The focus at this level is to stabilize the incident from a safe distance and prevent escalation, rather than actively confronting the hazard.

The other options, while relevant to different scenarios in emergency response, do not specifically define the primary action for Level 2. Evacuating personnel pertains more to situations requiring immediate safety measures but is not a primary action of Level 2 response. Controlling a hazardous incident suggests a more aggressive, hands-on approach generally associated with higher-level response scenarios. Identifying hazardous substances is critical but is more of a preliminary action rather than a response tactic aligned with the Level 2 framework.
