Part 31 Diving Operations


  • Rather than specify detailed procedural requirements in this Part, section 424 requires employers to meet the requirements of CSA Standard Z275.2-04, Occupational Safety Code for Diving Operations, to ensure that diving operations are performed safely.
  • Section 424 requires that divers meet the minimum requirements of CSA Standard Z275.4.02, Competency for Diving Operations.
  • Section 425 amends CSA Standard Z275.2-04 to provide divers with an added level of safety by requiring that the intake mechanism of a pipe, tunnel or duct be locked out. Stopping the flow associated with the intake is by itself insufficient.
