During an engine fire drill, what is the first step in the sequence?

• A. Pull the fire handle
• B. Cut fuel supply
• C. Discharge extinguisher into engine bay
• D. Power off

Answer: (A)

Act quickly to isolate the affected engine by pulling the engine fire handle. This action immediately cuts fuel to the engine, shuts down the engine’s controllable power sources, and arms the fire-extinguishing system for that engine. By removing the fuel source right away, you prevent the fire from feeding and give the extinguishing agent a better chance to do its job. After the handle is pulled, you proceed with discharging the extinguishing agent into the engine bay and then power down as required. The pull is the trigger that starts the whole sequence, enabling the subsequent steps to take effect.
