What should be done to manage an overhead locker fire?

Managing a fire in an overhead locker requires a careful and strategic approach, especially considering the confined space and potential for spreading flames. When faced with such a situation, assessing the severity of the fire is crucial. This assessment allows the crew members to determine the appropriate response and whether immediate action is needed.

Using Halon, a type of fire suppressant, is a vital step in managing such a fire effectively due to its suitability for electrical and flammable materials, which are often present in luggage. Halon can extinguish the fire quickly and minimize smoke, providing a safer environment for passengers and crew. It is important to note that opening the locker could introduce more oxygen to the flames, exacerbating the situation.

Closing the locker is not a long-term solution either; it may temporarily contain the fire but does not address the actual threat. Moreover, among the options provided, immediate evacuation without assessing the fire poses risks, as it may lead to panic and chaos without first determining if there is a manageable solution to the fire in the locker. Therefore, assessing the severity and subsequently deploying Halon represents the most effective approach to managing an overhead locker fire.
