STA 0+120Excavation and trench rules
Newfoundland and Labrador’s occupational health and safety rules set when an excavation must be sloped, shored or boxed, and when an engineer must design the protection.
- A worker shall not enter an excavation over 1.22 metres deep unless sides are sloped to a safe angle and secured by sheet piling, shoring and bracing or a trench box, or the worker is otherwise protected (s. 406(4)); 'trench' means an excavation less than 3.7 m wide at the bottom and more than 1.2 m deep (s. 376)1
- Before excavation with power tools/equipment in an area likely to have underground services, the employer must accurately determine and mark their location (s. 406(1)); spoil not within 1.22 m of a trench edge or 1.52 m of a pit edge (s. 408(1))1
