What is the SCUBA Normal Working Limit?

The SCUBA Normal Working Limit is established at 130 feet of seawater (fsw), which is considered a safe maximum depth for recreational divers using standard SCUBA equipment. This limit takes into account factors such as increased pressure, potential nitrogen narcosis, and the complexities of air supply management while diving.

Diving beyond this depth increases the risk of various physiological effects, such as the likelihood of experiencing nitrogen narcosis, which can impair judgment and physical abilities. Additionally, the increased pressure at depths greater than 130 fsw complicates the ascent and safety stops required for decompression as divers come back to the surface.

Staying within the Normal Working Limit helps divers maintain a safer diving experience and allows them to respond effectively to emergencies or unforeseen circumstances that may arise while underwater. This standard ensures the health and safety of divers, enabling them to enjoy the underwater experience without excessive risk.
