What is the purpose of the Protective Breathing Equipment (PBE) for crew members?

The Protective Breathing Equipment (PBE) is specifically designed to provide crew members with a safe air supply in environments that are compromised, such as smoke-filled areas. This equipment is crucial in situations where smoke can obstruct breathing, making it a vital safety measure for ensuring that personnel can effectively respond to emergencies, escape dangerous environments, or continue their duties without the risk of asphyxiation.

This function is paramount in aviation, where smoke incidents, whether from onboard fires or other hazards, pose significant threats. The PBE typically includes a hood that creates an airtight seal and delivers a supply of oxygen, allowing crew members to breathe safely while navigating through potentially hazardous conditions.
