341(1)This section applies to a surface-supply diving operation.
341(2)Where the planned depth of a dive does not exceed 30 m, an employer shall ensure that a minimum crew of three is present for each surface-supply diving operation consisting of
(a) a diver,
(b) a stand-by diver, and
(c) a tender.
341(3)A diving supervisor is not required for a dive referred to in subsection (2).

(a) a diver,
(b) a stand-by diver,
(c) a tender, and
(d) a diving supervisor who does not enter the water.
341(5)An employer shall ensure that a stationary air-line used in a surface-supply diving operation
(a) is properly safeguarded against injury or interference,
(b) has a valve fitted in each diver’s air-line that is
(i) readily accessible,
(ii) guarded against interference,
(iii) clearly marked to identify the diver whose air supply it controls, and
(iv) under the care of a competent person,

341(8)An employer shall ensure that a diver’s umbilical is taped to a life line at 1 m intervals in such a manner that strain due to tension on the life line does not create tension on the umbilical.
