Which protective action can an operations-level responder initiate?

An operations-level responder has specific duties and responsibilities defined by their training, which focuses on implementing procedures to control a hazardous materials incident without directly engaging in actions that require specialized skills beyond their level of training. Operating a remote valve is a task that aligns with these responsibilities, as it involves managing equipment to help control the flow or containment of hazardous materials, which is a standard procedure in mitigating risks at an incident scene.

This action does not necessarily involve direct human contact with the hazardous material or complex emergency medical interventions, allowing operations-level responders to act effectively within their scope of training and authority.

The other options, while critical responses to hazardous situations, generally fall outside the operational-level responder's certification. Evacuating the area requires broader authority and coordination, performing rescue operations typically demands higher training in technical rescue methods, and decontaminating a victim involves medical response capabilities that are also beyond the operational level. Thus, the ability to operate a remote valve is most fitting for the defined role of an operations-level responder in hazardous materials situations.
