What is the primary risk of diving beyond NDL?

Diving beyond the No Decompression Limit (NDL) is primarily associated with an increased risk of decompression sickness (DCS). The NDL represents a time limit within which a diver can ascend to the surface without the need for staged decompression stops. When a diver exceeds this limit, the body may accumulate excess nitrogen from breathing compressed air while underwater. As the diver ascends too quickly or without properly decompressing, nitrogen bubbles can form in the tissues and bloodstream. This can lead to DCS, which can cause severe symptoms and potentially life-threatening conditions.

It is important to adhere to NDL guidelines to ensure safe diving practices and minimize the risk of complications related to nitrogen saturation in the body. Understanding the effects of prolonged exposure to pressure and the need for adequate decompression is crucial for any diver.
