What action should be taken regarding portable oxygen bottles (POBs) during a fire?

During a fire situation, the highest priority is to ensure safety for both the crew and passengers. Moving portable oxygen bottles (POBs) away from the fire is critical because these bottles are under pressure and can become dangerous if exposed to flames or extreme heat. If a POB were to overheat or come in contact with a fire, it could result in an explosion or release of oxygen that could intensify the fire, posing a significant risk.

By relocating the POBs, you're minimizing the risk of them becoming hazardous while also ensuring that they remain available for use if needed in instances of smoke inhalation or if oxygen is required for any individuals with medical needs. Ensuring that the POBs are in a safe area can help create a safer environment for managing the fire and handling the emergency effectively.

The other options either do not prioritize safety in a fire emergency or could exacerbate the situation. For instance, using them immediately in the cabin without assessing the fire threat could lead to dangerous conditions. Keeping POBs stored during emergencies overlooks the potential need for oxygen in smoke-filled environments, while distributing them to all passengers without assessing the situation might create confusion or panic.
