Section 26-33. Reserve breathing gas and buoyancy compensator

For all types of breathing equipment used in connection with diving, each diver must have sufficient breathing gas to be able to get to a safe location. There must be sufficient reserve breathing gas for at least 10 minutes breathing at the maximum planned working depth calculated on the basis of a respiratory minute volume of 62.5 l/min. The required amount of reserve breathing gas will in no case exceed 2800 litres.
For scuba diving, a buoyancy compensator or equipment with a similar function that will bring the diver to the surface, must be used.
An exemption from the requirement in the first paragraph second sentence is made for rescue diving and training in rescue diving, and for recreational dive training and recreational dive guiding.
