When should a PBE be worn?

• A. When smoke or fumes are present
• B. Always
• C. Never
• D. Only during emergencies

Answer: (A)

Protective Breathing Equipment is used to shield your airway from smoke and toxic fumes by delivering clean air under positive pressure. Because smoke exposure can rapidly reduce visibility and impair breathing, you don the PBE as soon as smoke or fumes are present so you can continue to breathe safely, move, and assist others. It’s not worn continuously because the supply is finite and wearing it unnecessarily can be uncomfortable and wasteful. It isn’t appropriate to wear it only during some vague “emergency” separate from smoke, since smoke conditions themselves require protection. So, you wear the PBE whenever you detect smoke or fumes and keep it on until you’re clear of the hazard.
