How should casualties be approached if a hazard remains?

• A. Approach casualties immediately using standard PPE.
• B. Approach from outside the hazard boundary to provide aid when possible.
• C. Do not approach; treat only after the area is secured and the hazard is stabilized.
• D. Wait for a medical team to enter the area regardless of hazard.

Answer: (C)

The situation tests the priority of scene safety. When a hazard remains, you must not enter to treat casualties because moving into the area could trigger the hazard, injure you, or create more casualties. The correct approach is to keep people out and focus on securing the area and stabilizing the hazard first. Only after the scene is secured and the threat is under control should rescuers enter to provide medical care. This protects both rescuers and casualties by preventing secondary harm and ensuring that any treatment is delivered from a safe position. Approaching immediately with PPE, or entering from outside a vague boundary, can still expose you to danger if the hazard isn’t actually controlled. Waiting for a medical team to enter regardless of hazard risks leaving casualties without timely care, which isn’t acceptable when the hazard can be stabilized with proper scene management.
