During the overhead locker fire drill, which action is performed during the Attack phase?

• A. Discharge halon, close door, do not use water
• B. Identify - locate source of fire, assess severity
• C. Prepare - halon and fire gloves, non-BSI, open adjacent door
• D. Control - remove source and dampen down, check area

Answer: (A)

The Attack phase is about actively suppressing the fire and isolating the hazard to stop its spread. In an overhead locker fire, the quickest and safest way to do this is to discharge the extinguishing agent (halon) directly at the fire to interrupt the chemical reactions fueling the flame. Immediately after starting the discharge, closing the locker door helps confine the fire, limit airflow, and keep smoke and heat from spreading to other areas. Water is avoided here because it isn’t effective for electrical or confined-cabin fires and can cause steam, potential equipment damage, or electrical hazards; halon provides rapid, clean suppression in an enclosed space. The Attack phase thus centers on applying the extinguishing agent and isolating the area to enable effective firefighting.
