In the case of an external/internal/APU fire response, what should be done after notifying maintenance control?

In the event of an external, internal, or APU fire, the priority is to ensure the safety of all personnel in the vicinity. Notifying maintenance control is a crucial first step, as it allows for an organized and effective response to the emergency. After this notification, evacuating unnecessary personnel from the area is essential to minimize potential injuries and ensure that trained responders can focus on containing and extinguishing the fire.

Removing bystanders reduces the risk of panic and confusion, and it keeps the area clear for emergency services or maintenance crews that may need to access the aircraft. Personnel who are trained in fire response can then act without distraction or interference from those who are not involved in managing the emergency.

Other response options, such as discharging a fire extinguisher immediately, may be premature if there is a lack of situational awareness or significant risk of explosions or fire escalation. Assisting aircrew egress is important but usually must occur in conjunction with addressing the fire and ensuring the surrounding area is safe. Waiting for further instructions from the pilot can delay critical actions; immediate safety measures should take precedence to protect all personnel involved.
