312.23. Voice communication system: In addition to the system referred to in section 312.22, a 2-way voice communication system between the diver underwater and the dive team members on the surface must be used for all dives

(1)  that are surface-supplied;

(2)  with a buddy and free-swimming;

(3)  at the end of submerged pipes;

(4)  in an environment with an obstruction;

(5)  in a restricted access area;

(6)  under ice;

(7)  in a contaminated environment; and

(8)  to a depth of more than 40 m in the case of a police dive when the location does not allow the transportation of a hyperbaric chamber to the diving station.

During a dive to a depth of more than 50 m, the 2-way voice communication between the diver and the surface must be recorded for the entire dive. The recording must be kept for at least 48 hours.

A dive must be interrupted if the 2-way voice communication system should fail.
