During a secondary search, what determines when rescuers may remove SCBA?

• A. The atmosphere is safe per supervisor or safety officer
• B. They are bored
• C. All rooms are searched
• D. They are ordered by a passerby

Answer: (A)

SCBA may be removed during a secondary search only after the atmosphere has been declared safe by the supervisor or safety officer. This decision relies on air-monitoring readings and the overall environment—oxygen levels and the presence of any hazardous gases or contaminants—rather than how long you’ve been in the space or whether all rooms have been searched. A supervisor or safety officer uses gas detectors and safety protocols to confirm that hazards are controlled and unlikely to worsen before letting rescuers shed protective equipment. Choices based on boredom, simply finishing the search, or a passerby’s instruction do not address air safety and the established chain of command, which is why they’re not appropriate reasons to remove SCBA.
