Subsection 1: Provisions common to establishments organising underwater diving using air, oxygen or mixtures other than air

On the site of the underwater activity, diving is under the responsibility of a divemaster present at the place where the divers are launched or immersed. He or she is technically responsible for the organisation of the dive, the measures to be taken to ensure the safety of the divers and the activation of the emergency services. He ensures that the rules and procedures in force are applied. He sets…

Several divers who together make a dive with the same characteristics of duration, depth and path, even if they breathe different mixes, constitute a group. When the group is made up of divers with different skills or breathing different mixes, it must not exceed the maximum operating conditions available to the diver with the most restrictive skills or the most restrictive mix. Minors are not allowed to dive autonomously.

When, in the natural environment, the submerged group is led by a supervisor, that supervisor must hold a qualification mentioned in Annex III-15 b. This person is responsible for the conduct of the dive and ensures that its characteristics are appropriate to the circumstances and the abilities of the divers. When at least one of the supervised divers or the person supervising the group uses a mixture other than air,…

For the purposes of this section, exploration diving means diving without any teaching.

Depending on the gases used, the level of qualification of the supervisors and the skills of the divers, the diving areas are defined as follows: 0 to 6 metres; 0 to 12 metres; 0 to 20 metres; 0 to 40 metres; 0 to 60 metres; Space from 0 to 70 metres; Space from 0 to 80 metres; Spaces above 80 metres. Underwater diving with air is limited to 60 metres….

The diver shall provide proof to the diving master of the skills mentioned in Annexes III-14 a, III-17 a or III-18 a, in particular by presenting a certificate or diploma and, where appropriate, a logbook enabling the diver’s experience to be evaluated. In the absence of such proof, the diving master shall arrange for an assessment of the diver’s abilities to be made after one or more dives. A diver…

I.-Practitioners have a rescue plan and the following rescue equipment available at the launch or immersion site: -A means of communication to alert the emergency services. A VHF is necessary when the dive takes place at sea from a dive support boat; -Fresh drinking water; a self-filling bag with a one-way valve, an oxygen reserve bag and three masks (large, medium and small); a high-concentration mask -a set of normobaric…

Diving activities are marked out in accordance with current regulations.

Each cylinder or set of cylinders of the same breathing gas is fitted with a pressure gauge or equivalent system to indicate the pressure during the dive. In the natural environment, each diver equipped with open circuit equipment is fitted with a compressed gas inflatable system enabling him or her to return to the surface and remain there. In the natural environment, each supervised diver above 20 metres and each…

Underwater equipment used by divers is regularly checked and properly maintained. Snorkels and regulators made available to divers by the establishments are disinfected before each dive if there is a change of user.
