What is the SCUBA Max Working Limit?

The correct answer, which indicates that the SCUBA Max Working Limit is 190 feet of seawater (fsw), reflects the generally accepted maximum depth limit for recreational SCUBA diving. This depth is significant because it encompasses the threshold where professional diving practices often transition into technical diving due to increased risk factors associated with depth, such as nitrogen narcosis and oxygen toxicity.

At 190 fsw, divers are required to utilize advanced training, specialized equipment, and often mixed gas to safely manage the physiological challenges presented by such depths. This limit is established based on accumulated knowledge in diving safety and the experiences of professional divers in the field. It signifies the importance of adhering to these limits to ensure safety and to maximize the benefits of SCUBA training and technology.
