PART VSupervisors (continued)
Oxygen Supply Systems and Breathing Mixture Supply Systems
48 (1) No supervisor shall conduct a diving operation in which
(a) an oxygen supply system is used unless the oxygen supply system meets the requirements set out in section 19;
(b) a breathing mixture supply system is used unless the breathing mixture supply system meets the requirements set out in sections 20 and 21; and
(c) an analyser is used to determine the relative levels of oxygen and carbon dioxide during any dive that is part of the diving operation unless the analyser is recalibrated in accordance with the manufacturer’s instructions for that analyser prior to the dive.
(2) Where an analyser is used continuously in a diving operation to determine the relative levels of oxygen and carbon dioxide during any dive that is part of the diving operation, the supervisor of the dive shall ensure that the analyser is recalibrated in accordance with the manufacturer’s instructions for that analyser, where practicable, every two hours.
(3) No diving supervisor shall, in a diving operation supervised by the supervisor, use or permit to be used an on-line gas blender or a diver’s gas recovery system in the diving operation unless throughout the period that the blender or the diver’s gas recovery system is in use the requirements of section 21 are complied with.
Breathing Mixture
49 (1) No supervisor shall commence or continue a diving operation unless
(a) the total quantity of appropriate breathing mixture that is available at any time during the diving operation consists of the quantities set out in section 22;
(b) the purity of the breathing mixture is of an acceptable standard; and
(c) the quantities of breathing mixture referred to in subparagraphs 22(1)(a)(ii) and (iii) are available for immediate use at a flow rate, temperature and pressure that are safe for the user.
(2) No supervisor shall permit a diver supervised by the supervisor to make a dive unless
(a) the total quantity of appropriate breathing mixture, including the reserve supply,
(i) carried by the diver is sufficient to enable that diver to reach a skip, diving bell or diving submersible used in connection with the dive, a reserve supply referred to in subparagraph 22(1)(a)(ii) or the surface, and
(ii) available to the diver’s stand-by diver for immediate use consists of an adequate quantity to enable the stand-by diver to reach the diver and to enable the stand-by diver and the diver
(A) to carry out appropriate decompression procedures and return to the surface, or
(B) to return to the skip, diving bell or diving submersible used in connection with the dive and to carry out appropriate decompression procedures either in that skip, diving bell or diving submersible, as the case may be, or at the surface; and
(b) the supervisor has analysed the breathing mixture for the accuracy of its oxygen content immediately prior to the dive.
(3) No supervisor shall, in a diving operation supervised by the supervisor, use or permit to be used
(a) compressed air as a breathing mixture at water depths greater than 50 m or at pressures that are equivalent to the pressures of water depths greater than 50 m except in the case of a category III dive; or
(b) pure oxygen as a breathing mixture except for decompression or therapeutic purposes.
(4) A supervisor shall protect any breathing mixture to be used in a diving operation supervised by the supervisor from any likelihood of contamination.
(5) Where a diving supervisor becomes aware of any oil or other contaminant in waters in which a diving operation supervised by the supervisor is being conducted, that supervisor shall take all necessary steps to avoid any contamination of any diver in the water and of the ambient atmosphere in any compression chamber used in the diving operation.
