What is the primary focus of initial ARFF units during an incident?

• A. Rescue operations
• B. Extinguishment to protect evacuation routes
• C. Monitoring fire growth
• D. Setting up a command post

Answer: (B)

The primary focus of initial Aircraft Rescue and Fire Fighting (ARFF) units during an incident is to conduct extinguishment efforts to protect evacuation routes. When an aircraft incident occurs, the immediate priority is the safety of passengers and crew, which includes ensuring that escape routes are clear and protected from fire. This means that fire suppression must be initiated swiftly at the aircraft's impact site or involved areas to allow for safe egress of individuals on board.

This necessity for immediate action centers on both preventing fire from spreading and facilitating the evacuation of any survivors. Ensuring that evacuation paths remain safe allows for a fast and organized exit from the aircraft, which is crucial in emergency situations.

While other elements like setting up a command post, monitoring fire growth, or conducting rescue operations are also important, they do not take precedence over the critical need to establish and maintain clear evacuation routes. The urgency and potential for injury or loss of life dictate that flame control is the top priority for initial responders in ARFF operations.
