Which is NOT a common error when conducting the purge?

• A. Over-inflating the breathing bag
• B. Inadequate purge duration
• C. Not fully closing the purge valve
• D. Breathing too rapidly

Answer: (A)

When purging, the goal is to clear water from the breathing loop by letting enough gas flow through for a complete flush. Over-inflating the breathing bag isn’t a purge issue you typically troubleshoot during the purge task; bag inflation mainly affects buoyancy and comfort, not the effectiveness of flushing water from the loop. The mistakes you’re most concerned with during purge are not letting it run long enough (inadequate purge duration), leaving the purge valve not fully closed (which can allow bypass or leaks that prevent a proper purge), and breathing too rapidly (which can disrupt steady gas flow and hinder the purge’s ability to clear water). So over-inflating the bag doesn’t reflect a common purge error, making it the best choice here.
