In the event of a surface interval exceeding 7 minutes, what treatment table should divers be placed on?

The correct approach in the situation where a surface interval exceeds 7 minutes is to place divers on Treatment Table 6. This treatment protocol is specifically designed for scenarios where divers may experience longer breaks between dives, which could increase the risk of decompression sickness if proper precautions are not taken. Treatment Table 6 typically involves a carefully structured decompression schedule that helps manage the increased nitrogen load in a diver's body resulting from exceeding the recommended surface intervals.

In this table, the diver will undergo a series of pressure and time intervals that are meant to facilitate safe off-gassing of nitrogen. This ensures that the diver's body can adequately eliminate excess nitrogen that has accumulated during the previous dive. Utilizing such structured treatment protocols like Treatment Table 6 is essential in mitigating the risks associated with longer surface intervals and ensuring diver safety.
