What does "PBE" stand for in emergency situations?

The term "PBE" in emergency situations stands for "Protective Breathing Equipment." This equipment is critical for providing flight attendants and crew with a supply of breathable air in smoke-filled or toxic environments, helping them maintain their safety and perform their duties effectively during emergencies. Protective Breathing Equipment is specifically designed to shield the user from harmful gases or smoke, ensuring that they can continue to help passengers and manage the situation without compromising their health or safety. The other terms, although they contain similar words, do not accurately reflect the standard terminology used in aviation safety protocols.
