All divers, diving supervisors, and divers' tenders must also be trained in CPR, oxygen (O2) therapy, and diving accident management. WorkSafeBC may recognize commercial diver certification from other jurisdictions. These out-of-jurisdiction certificates are evaluated on a case-by-case basis by the Certification Services department of WorkSafeBC. For questions about whether a diver has been certified to a standard acceptable to WorkSafeBC, please contact WorkSafeBC's diving coordinator at 604.276.3100.
