How long does an EEBD last when in use?

The duration of an Emergency Escape Breathing Device (EEBD) when in use is typically around 10 minutes. This timeframe is designed to provide enough breathable air for a person to escape a hazardous environment, such as one filled with smoke or toxic gases. The 10-minute mark is crucial as it allows sufficient time to navigate out of danger while ensuring that the device remains lightweight and portable for easy use.

The choice of 10 minutes balances the need for effectiveness in an emergency escape situation while keeping the device compact and manageable. Longer durations would add weight and size to the device, making it less practical for quick access and use during emergencies.

In this context, other duration options may not meet the requirements of an effective escape tool. For instance, a 5-minute duration wouldn't provide enough air for safe evacuation, especially in environments where the escape route may be obstructed or require additional time to navigate. Conversely, options like 15 or 20 minutes, while seemingly advantageous, would complicate the device's design and usability for the purpose it serves.
