Minimum rest time following depletion of one 30-minute air cylinder?

• A. 5 Minutes
• B. 15 Minutes
• C. There Is No Recommended Minimum
• D. 10 Minutes

Answer: (D)

When a firefighter finishes using a 30-minute SCBA cylinder, the body needs time to recover from that exertion and to be assessed for safety before resuming work. The minimum recovery period recommended by rehab guidelines is ten minutes. This interval allows vital signs such as heart rate and breathing to begin returning toward baseline, supports rehydration and cooling, and provides an opportunity for supervision and any necessary vitals checks. Five minutes is usually too short for meaningful physiologic recovery after heavy work, and fifteen minutes, while safe, goes beyond the minimum. There is a recommended minimum rest time, and ten minutes is that standard. If symptoms persist, longer rest or medical evaluation would be warranted.
