True or False: Repetitive dives are authorized when exceeding the normal working limits of Table 10-1?

• A. True
• B. False
• C. Not enough information
• D. Only with CO approval

Answer: (B)

Repetitive dives are governed by published limits that keep nitrogen loading within safe levels. Table 10-1 defines the maximum depth-time combinations and required surface intervals for diving multiple times in a row. If you exceed those normal working limits, you’re stepping outside the safe envelope, and continuing to sequence more repetitive dives would raise the risk of decompression sickness. Therefore, you cannot authorize additional repetitive dives beyond those limits. The proper course is to end the current dive, surface, and either wait the required interval until you’re back within limits or follow any decompression requirements before diving again. CO approval does not override these safety limits, and there isn’t extra information that would change this safety rule.
