Which statement about the bailout bottle is correct?

• A. It is used as the primary air source
• B. It must be kept on the surface
• C. It provides emergency breathing gas to the diver
• D. It is only for training dives

Answer: (C)

A bailout bottle is a secondary, independent source of breathing gas carried by a diver to handle emergencies. Its job is to provide emergency breathing gas if the main cylinder or regulator fails, so the diver can stay conscious, manage the problem, share air if needed, and work toward a safe ascent or to reach an alternative gas source. It is not the primary air source; normal breathing comes from the main cylinder during the dive. The bailout bottle is worn or mounted on the diver, not kept on the surface, so it’s available underwater when needed. It’s not limited to training dives—the bailout bottle is a true safety device used in real dives to increase options and time to solve problems in case of gas loss.
