How long can the oxygen generator-based system provide a constant concentration after activation?

• A. 5 minutes
• B. 8 minutes
• C. 12 minutes minimum
• D. 20 minutes

Answer: (C)

Chemical oxygen generators provide a constant, high-purity oxygen concentration by a controlled chemical reaction. Once activated, the system maintains this steady concentration for the duration the generator cartridges are designed to last. The cartridges are sized to ensure a stable supply for at least 12 minutes, even if the wearer breathes more vigorously. After that minimum period, the supply may be exhausted unless another source takes over. Hence, the duration you can count on is a minimum of 12 minutes.
