What is the role of the Incident Safety Officer (ISO)?

• A. Direct the attack team
• B. Monitor safety, identify hazards, and stop unsafe operations; ensure crew safety
• C. Manage the water supply
• D. Coordinate ventilation

Answer: (B)

The main concept is that the Incident Safety Officer is there to protect people on the scene by actively watching for hazards and stopping risky actions before they cause harm. On a fire scene, the ISO monitors safety conditions, identifies hazardous situations, and has the authority to halt any operation that could put firefighters or personnel at risk, all with the goal of keeping crews safe.

This explains why the described role is the best fit: the ISO’s primary function is to oversee safety, continually assess risks, and intervene to prevent unsafe work practices. While directing the attack, managing water supply, or coordinating ventilation are important responsibilities in their own right, those tasks fall under other command roles and operational teams. The safety officer’s focus is specifically on maintaining a safe operating environment and ensuring that safety procedures are followed, even if that means stopping work temporarily to prevent harm.
