If you experience an electrical fire, what should be checked first?

When dealing with an electrical fire, one of the primary concerns is to ensure that there is no potential for additional hazards, such as a malfunctioning On-Board Oxygen Generation System (OBOGS). This system generates oxygen for the crew, and if it were to be compromised or malfunction during an electrical fire, it could exacerbate the situation by introducing toxic fumes or creating further complications during the emergency. Inspecting the OBOGS system can ensure that the crew maintains a safe and breathable atmosphere, which is crucial for managing the fire and executing emergency procedures effectively.

In contrast, while checking the fire control panel, emergency landing procedures, and flight instruments are certainly important when dealing with a fire situation, they do not address the immediate safety of the crew in terms of air quality and breathable oxygen as directly as evaluating the OBOGS system does. Also, the fire control panel would provide information on the fire status, but it doesn't directly mitigate the risks involved. Emergency landing procedures and flight instruments are more relevant once the immediate threat of the fire has been assessed and managed.
