When a fire involves the engine compartment, what action should be taken to prevent feeding the fire?

• A. Open all vents to balance air.
• B. Shut off engines, generators and ventilation, keep compartment shut to prevent fresh air from feeding the fire.
• C. Do nothing.
• D. Increase airflow by turning on fresh air.

Answer: (B)

When a fire is in the engine compartment, the goal is to starve the flame by removing its oxygen and fuel sources. The best action is to shut down all potential sources of air and power: turn off the engines, generators, and ventilation, and keep the compartment closed to prevent fresh air from entering. This cuts off the air supply that feeds the fire and helps contain it until firefighting measures can be applied. Opening vents or increasing airflow would feed the fire with more oxygen, making it burn hotter and spread faster. Doing nothing offers no stopgap against the flames.
