Under what circumstances should an SCBA be removed from service?

• A. If there is persistent leakage, obvious damage, or malfunction that cannot be immediately corrected, or in uncertain conditions where the unit cannot provide safe air.
• B. If the user forgets to bring it to work.
• C. If the weather is hot.
• D. If the cylinder is full.

Answer: (A)

SCBA should be removed from service whenever it cannot guarantee safe breathing air for the wearer. This includes situations where there is persistent leakage, obvious damage, or a malfunction that cannot be corrected immediately. If any part of the unit is compromised—such as leaking hoses or seals, cracked or damaged components, or regulators and alarms that don’t function properly—the device must be taken out of service to prevent a dangerous loss of air or exposure to harmful atmospheres. If conditions are uncertain and the unit cannot be trusted to provide safe air, it should also be removed and inspected before reuse. Other options don’t indicate an equipment fault or safety risk, so they don’t require removal. Forgetting to bring it to work is a logistical issue, hot weather may affect comfort but doesn’t inherently make the SCBA unsafe, and a full cylinder simply means there is enough air for now and isn’t itself a safety issue.
