What defines a "no-decompression limit" for divers?

• A. The maximum depth a diver can go
• B. The time a diver can stay at a depth without performing decompression stops
• C. The duration before a diver must surface
• D. The total time spent underwater

Answer: (B)

The "no-decompression limit" specifically refers to the maximum duration that a diver can remain at a given depth without needing to perform decompression stops during ascent. When divers exceed this limit, their bodies may accumulate nitrogen, leading to the risk of decompression sickness if they ascend too quickly or without adequate stops to allow for safe nitrogen elimination. This limit is crucial for ensuring diver safety, allowing for a direct ascent to the surface without the added risks associated with needing to stop and safely off-gas nitrogen. Therefore, understanding and adhering to no-decompression limits is essential in planning safe dives and managing underwater time effectively.
