Final answer:
Emergency Escape Breathing Devices (EEBDs) are used for emergency evacuation in smoke-filled environments, not for firefighting, scuba diving, or oxygen therapy in hospitals. They provide a short-term supply of clean air for safe escape. Scuba diving devices differ in technology and functionality.
Step-by-step explanation:
EEBDs, or Emergency Escape Breathing Devices, are used primarily for emergency evacuation in smoke-filled environments. They are not used for firefighting, scuba diving or oxygen therapy in hospitals. The purpose of an EEBD is to provide the user with a short term supply of clean air to allow them to escape safely from a dangerous situation, such as a fire or a chemical spill. It's worth noting that while scuba divers also use breathing devices, these devices are specially designed for underwater use and involve different technology and functionality compared to EEBDs.
