312.39. Stage: A stage must be used to move divers to the entry point into the water if the diving station is more than 2 m above water.
The stage must(1) be built to prevent tipping or spinning;
(2) have a floor surface of at least 0.83 m2; and
(3) be able to support the weight of at least 2 divers with their diving equipment.
If the stage is a cage, submersible compression chamber, platform or diving bell, it must meet, in addition to the requirements referred to in the second paragraph, the requirements referred to in paragraph 3 of section 3.10.7 of the Safety Code for the construction industry (chapter S-2.1, r. 4), except subparagraph d of that paragraph.
If the entry point into the water is 2 m or less from the water surface and there is no stage, a ladder must be available to the divers.
When the site’s configuration does not allow for a stage to be used, another means providing equivalent safety may be used to move the diver to the entry point. The drawings of the means must be prepared by an engineer and available at the diving station.
