Which statement about the functions of an EEBD is true?

Emergency Escape Breathing Devices (EEBD) are specifically designed for situations where individuals need to evacuate quickly from hazardous environments, such as smoke-filled or toxic areas. Their primary function is to provide a safe means of escape by supplying breathable air for a limited duration. This makes the statement about their intention for emergency escape accurate.

While EEBDs can be used in training situations, that is not their primary function, which is why the first option does not reflect their main purpose. The second statement about being interchangeable with regular breathing apparatus is misleading, as regular breathing apparatus is typically designed for prolonged use in hazardous environments, while EEBDs are for short-term emergency situations. While some EEBD models can provide air for a duration close to 30 minutes, many are designed to last less than that, focusing instead on quick escape. Thus, the focus on emergency escape aligns correctly with the true nature of EEBDs.
