Which of the following is a step to take in case of fire?

1. Turn off electrical equipment

2. Increase cabin pressure

3. Unlock emergency exits

4. Activate landing gear

The correct answer is: Turn off electrical equipment

Turning off electrical equipment is a crucial step to take in the event of a fire. This action helps to reduce the risk of further ignition, as many electrical systems can continue to generate sparks or heat, exacerbating the fire situation. By deactivating electrical equipment, it minimizes potential hazards associated with electrical fires, which can be particularly destructive in an enclosed environment. Other options, while possibly relevant procedures in specific scenarios, do not directly contribute to addressing a fire emergency. Increasing cabin pressure is typically unrelated to fire response and could potentially hinder evacuation efforts if necessary. Unlocking emergency exits may be important for evacuation but should follow actions that mitigate the fire risk. Activating landing gear is irrelevant in the context of fire response, as it pertains to aircraft operation rather than dealing with emergency situations on board.
