What is the working limit for SCUBA diving?

The working limit for SCUBA diving is typically considered to be 130 feet of seawater (fsw). This depth is significant because it aligns with the recreational diving limits as established by many training agencies, which recommend that divers remain within 130 fsw to minimize the risks associated with increased pressure, such as nitrogen narcosis and the complexities of managing decompression schedules.

This depth is also critical for the safety, ease of training, and emergency response, ensuring that divers can return to the surface without requiring complex decompression procedures. Exceeding this limit can expose divers to a higher risk of serious physiological effects due to the underwater environment. Therefore, sticking to the working limit of 130 fsw helps maintain safety standards and allows divers to operate within an effective range where they can utilize their training and experience optimally.
