Diving hazards
314(1)Immediately before each dive, a diving supervisor shall review the nature of the hazards in the diving area and ensure that each diver fully understands the hazards involved.
314(2)A diving supervisor shall declare underwater approaches to an intake or an exhaust a hazardous area for an underwater diving operation.
314(3)A diving supervisor shall ensure that a diver
(a) in a hazardous area wears at all times a life line tended from a position outside the hazardous area,
(b) required to approach an underwater intake, exhaust, pipe, tunnel or duct is able to differentiate it from any other similar object in the area, and
(c) does not approach an intake or exhaust until the flow through it is, in the case of an intake, arrested and locked out, or, in the case of an exhaust, slowed down, to the extent it is safe for a diver to work near the intake or exhaust and provisions are made so that the flow will not be re-established until the diver leaves the water or is declared by the diving supervisor to be clear of the hazardous area.
314(4)Before a diver approaches an area that may be hazardous because of the operation of a mechanism, a diving supervisor shall ensure that the mechanism is
(a) secured against inadvertent movement before the diver enters the water, and
(b) rendered inoperative and prevented from being activated by isolating the energy source from the mechanism in a manner suitable to the diver and the diving supervisor.
314(5)Where exceptional hazards exist or are predicted, an employer and a diving supervisor shall ensure that a second diving crew with independent diving plant and equipment capable of effecting rescue is on the site of the underwater diving operation.
