The steps that are taken to preserve the health and safety of emergency responders and the public during an incident involving release of hazardous materials.

• A. Risk Assessment
• B. Scene Control
• C. Protective Actions
• D. Public Notification

Answer: (C)

Protective actions are the steps taken to shield emergency responders and the public from exposure to hazardous materials during an incident. These actions are chosen and implemented to reduce or eliminate exposure and can include evacuating people from the affected area, sheltering in place to keep people indoors and away from contaminant entry points, and establishing exclusion zones or traffic controls so no one enters the danger area. The goal is to minimize health risks until the incident is contained and responders can operate safely.

Risk assessment looks at hazards and the level of risk to determine priorities, but it’s the protective actions that translate that assessment into concrete safety measures. Scene control aims to secure the area and limit access, which supports safety but is about managing the site rather than directly protecting people through actions like evacuation or sheltering. Public notification involves informing people about the incident, which is important for awareness but does not by itself constitute the protective steps used to reduce exposure.
