If a POB is being used during an emergency, how should it be handled?

Keeping the portable oxygen bottle (POB) accessible at all times during an emergency is essential for several reasons. In a situation requiring supplemental oxygen, individuals may experience varying levels of oxygen deprivation and respiratory distress. Ensuring that the POB is within reach allows for immediate access to oxygen, which can be critical in stabilizing a person's condition and providing the necessary support in an emergency.

Accessibility helps to minimize response time when oxygen is needed urgently, which can significantly impact the outcomes for those in distress. This proactive measure enables individuals administering aid to respond swiftly and effectively, reducing the time that someone might be in a compromised state due to lack of oxygen.

In comparison, while it might seem practical to pass the POB around as needed, this could delay access for someone in critical need. Securing the POB if it's no longer in use does not address the immediate needs of others who may suddenly require it during the ongoing emergency. Lastly, waiting to return it to the kit only after landing could lead to a situation where someone is deprived of oxygen when they actually need it during the flight. Thus, keeping the POB accessible at all times ensures a higher level of readiness and safety in emergencies.
