Don't Go Overboard: Safe Work On and Near Water

Yes. Under Ontario's O. Reg. 213/91 (Sections 137–142), Alberta's OHS Code Part 10, and BC's OHS Regulation Part 24, employers must provide approved flotation equipment and require workers to wear it whenever they are working on or near water. PFDs must carry Transport Canada, Canadian Coast Guard, or Fisheries and Oceans Canada approval - no other certification standard is acceptable on a Canadian worksite. The equipment must also be inspected before each use and removed from service if any defect is found.

The 1-10-1 rule describes the three survival windows after falling into cold water: you have roughly 1 minute to control the cold shock gasp reflex, 10 minutes of meaningful muscle function for self-rescue, and up to 1 hour before hypothermia causes unconsciousness. BC's OHS Regulation Part 24 and Alberta's OHS Code Part 10 both require workers exposed to cold water to receive training on cold water immersion response. Canadian lakes and coastal waters rarely exceed 20°C even in summer, so cold shock is a year-round risk - not just a winter one.

The minimum ice thickness for a single person walking on clear blue ice is 10 cm (4 inches), as specified under Alberta's OHS Code Part 10, Section 223. Ice thickness must be verified with an auger or drill before access and continuously tested as workers move across the surface. White or milky ice has roughly half the strength of clear blue ice, so the thickness requirement doubles; grey or dark ice must never be accessed regardless of thickness. A flotation suit, ice picks worn around the neck, and a buddy on solid ground with a throw line are mandatory for all ice work.

Yes - failure to have a written Emergency Response Plan (ERP) is a citable offence in every Canadian jurisdiction. Alberta's OHS Code Section 225 and BC's OHS Regulation Section 24.1 both require the plan to exist before work begins, and it must include emergency contact numbers, rescue equipment locations, evacuation routes, and the location of a standby rescue boat where required. Employers are also required to conduct regular man overboard drills; sites without practiced drills take 3 to 5 times longer to initiate rescue than sites that drill quarterly.

Canadian OHS regulations define two categories: working 'on water' (boats, barges, floating platforms, and ice covers) and working 'near water' (bridges, piers, docks, shorelines, riverbanks, cofferdams, and excavations adjacent to water). Both categories trigger mandatory fall protection and flotation requirements. Alberta's OHS Code Part 10 and Ontario's O. Reg. 213/91 Sections 137–142 explicitly cover bridge and dock workers even when no vessel is involved. A site-specific hazard assessment considering season, water temperature, current speed, and emergency access is required before work begins in any of these settings.
