The Saskatchewan Employment Act requires employers and contractors to take extensive precautions to protect workers engaged in excavations, trenching, shaft sinking and tunneling operations.
The Occupational Health and Safety Regulations, 2020 contain the regulated safety standards for excavations, excavated shafts, trenches and tunnels. In addition, employers and contractors should consult municipal and city bylaws for the area where they are working. The public should be warned about any applicable hazards that could reasonably be expected to occur during an excavation project.
WorkSafe Saskatchewan's publication Safety in Excavations and Trenches is a resource for employers and contractors. It provides information to help prevent harmful incidents to workers when excavating.
