What might happen if a diver does not avoid maximum dive table limits?

If a diver does not adhere to the maximum dive table limits, they may face a higher risk of decompression sickness (DCS). Dive tables are designed to provide safe limits for time and depth during underwater activities, considering various factors such as nitrogen absorption in the body.

When a diver exceeds these limits, particularly in terms of depth or duration, the body absorbs more nitrogen than can safely be removed during ascent and surface intervals. Upon surfacing, if this excess nitrogen is released too quickly, it can form bubbles in the bloodstream and tissues, leading to DCS. Symptoms can range from joint pain and dizziness to more severe complications that could be life-threatening.

The other choices do not accurately reflect the consequences of ignoring dive table limits. Increased buoyancy and better visibility underwater are not related to the dive table limits and do not impact safety negatively. The assertion of "no impact on the dive" directly contradicts the established protocols aiming to ensure divers' safety and health. Therefore, recognizing the correlation between dive limits and the risk of DCS is crucial for safe diving practices.
