What activity is specifically excluded from standard divers due to its risks?

Exceptional exposure diving is specifically excluded from standard divers due to its inherent risks. This type of diving often involves conditions that surpass the normal safe parameters for divers, including factors such as extreme depths, long durations, or impaired visibility. These scenarios pose greater risks of decompression sickness, hypoxia, or equipment failure. Consequently, standard divers are typically not trained for these hazardous situations, which require specialized training, additional safety measures, and advanced equipment to handle the associated dangers effectively. In contrast, the other activities mentioned, such as shallow water diving, swim testing, and routine equipment checks, are considered standard procedures that divers are trained to manage within safe guidelines.
