Division 3.11 Safety devices for diving equipment

Breathing equipment

The breathing equipment must make it possible to supply the user with a breathable gaseous mixture, under foreseeable conditions of use and taking account in particular of the maximum depth of immersion.

Where the foreseeable conditions of use so require, the equipment must comprise:

1. (a)

   a suit which protects the user against the pressure resulting from the depth of immersion (see 3.2) and/or against cold (see 3.7);

2. (b)

   an alarm designed to give the user prompt warning of an approaching failure in the supply of breathable gaseous mixture (see 2.8);

3. (c)

   a life-saving suit enabling the user to return to the surface (see 3.4.1).
