For what duration should an EEBD be used in an emergency situation?

In emergency situations, the Emergency Escape Breathing Device (EEBD) is designed to provide a limited supply of breathable air to individuals escaping from hazardous environments, such as those with smoke or toxic gases. The key to ensuring safety during an emergency is to use the EEBD for the duration that allows for safe evacuation without exceeding its functional limit.

The functional limit refers to the maximum amount of time or the volume of air that the EEBD can provide before it runs out. Once the device has reached its limit, it may no longer provide breathable air, putting the user at significant risk. Therefore, it is crucial to utilize the EEBD within its designed operational time frame, which allows for the best chance of safe relief from danger while facilitating a quick and effective evacuation.

In contrast, simply using it until help arrives or until oxygen levels are normal may extend the use beyond the safe operational limit of the device, which can lead to dangerous situations. Additionally, focusing on the minimum required time to evacuate does not account for the actual limitations of the device. Thus, understanding and adhering to the functional limit of the EEBD ensures safe usage and effective escape during an emergency.
