The OCFA bottle duration is which value?

• A. 60 minutes
• B. 45 minutes
• C. 15 minutes
• D. 30 minutes

Answer: (D)

Air supply duration on an SCBA bottle is the time the air will last under standard breathing conditions, based on the bottle’s capacity and service pressure. For OCFA, the standard configuration uses a 30-minute bottle, which gives firefighters a predictable window to operate and manage air while inside a structure. Actual air used depends on how hard you work and your breathing rate, but the 30-minute rating serves as the baseline for planning and safety. There are bottles with longer durations in other departments or configurations, but OCFA’s typical setup is 30 minutes.
