How should FA 2 respond after donning protective breathing equipment?

After donning protective breathing equipment, it is essential for FA 2 to relieve FA 1 and continue fighting the fire to ensure the safety of the passengers and crew. The use of protective breathing equipment indicates that there is a serious smoke or fire hazard, and immediate action is required to contain the situation.

Continuing to fight the fire not only helps mitigate the threat of smoke and flames spreading within the cabin but also demonstrates a coordinated response to managing the emergency. This action prioritizes the safety of everyone on board while minimizing the risk of escalating the situation.

In response to the other choices, evacuating the cabin may be necessary but should not happen until the fire hazard is controlled or assessed. Alerting passengers to stay seated is important but doesn’t address the critical need for immediate action against the fire. Checking fire extinguishers is a proactive measure, but at this point, the focus should be on using the available equipment and personnel to combat the fire actively. Thus, continuing the fight against the fire is the most appropriate and urgent response following the donning of protective equipment.
