What British Columbia requires
- Every employer ensures regular inspections of all workplaces, including buildings, structures, grounds, excavations, tools, equipment, machinery and work methods and practices, at intervals that will prevent the development of unsafe working conditionsOHS Regulation (B.C. Reg. 296/97), s. 3.5 · B.C. Reg. 296/97, s. 3.5 (BC Laws, official consolidation)
- Unsafe or harmful conditions found in the course of an inspection must be remedied without delayOHS Regulation, s. 3.9 · B.C. Reg. 296/97, s. 3.9 (BC Laws, official consolidation)
- On a construction project with more than one employer, each employer tells the owner or prime contractor in advance of work likely to create a hazard for another employer's workers; where overlapping or adjoining work creates a hazard and the combined workforce is more than 5, the owner or prime contractor appoints a qualified coordinator and keeps on site the coordinator's name, a posted site drawing showing the project layout, first aid location, emergency transportation and evacuation marshalling station, and the construction safety proceduresOHS Regulation, s. 20.3
- A fall protection system is used where work is done at a place from which a fall of 3 m or more may occur, or where a lower fall carries a risk of injury greater than impact on a flat surface; guardrails or similar fall restraint are used when practicable, otherwise another fall restraint system, then fall arrest or rope access, and only then work procedures acceptable to WorkSafeBC; workers are instructed in the area's fall protection system before enteringOHS Regulation, s. 11.2
- The employer has a written fall protection plan where workers are not protected by permanent guardrails and a fall of 7.5 m or more may occur, or where work procedures replace fall protection equipment; the plan is available at the workplace before work with a risk of falling beginsOHS Regulation, s. 11.3
- Equipment used in a fall protection system is inspected by a qualified person before use on each workshift, kept free from substances and conditions that could make it deteriorate, and maintained in good working orderOHS Regulation, s. 11.9
- A stairway made of at least framing, treads and a handrail is provided to each floor level before construction of the next floor or deck begins, and its treads must not create a tripping or slipping hazardOHS Regulation, s. 20.5 (5)
- Before a worker enters an excavation over 1.2 m deep, or comes closer to its side than the excavation's depth, the sides are sloped, benched or supported (as a qualified registered professional or engineer specifies, by the regulation's tables, or by trench boxes, shoring cages or other effective means)OHS Regulation, s. 20.81 (1)
- Before excavating or drilling with powered equipment, the location of all underground utility services is accurately determined; where workers enter a trench over 1.2 m deep, a safe entry and exit point is within 8 m of them; excavated material is kept at least 60 cm back from the edge of a trench and 1.2 m from any other excavationOHS Regulation, s. 20.79 (1) · OHS Regulation, ss. 20.87 (2), 20.90 (1)
- Excavation work follows the written, certified instructions of a qualified registered professional, kept at the site, when the excavation is more than 6 m deep, is next to an improvement or structure, is subject to vibration or hydrostatic pressure, or the ground slopes away from the edge steeper than 3 horizontal to 1 vertical; a professional engineer's instructions where it uses support structuresOHS Regulation, s. 20.78
Regular inspections and site coordination
Employers inspect buildings, structures, grounds, excavations, tools, equipment and work practices at intervals that prevent unsafe conditions from developing, and anything unsafe found is fixed without delay.
When more than one employer works on a project, each tells the owner or prime contractor ahead of work that could endanger others. Where overlapping work creates a hazard and more than 5 workers are on site, the owner or prime contractor appoints a qualified coordinator and keeps a posted site drawing showing the layout, first aid, emergency transportation and the evacuation marshalling station. Each floor gets a stairway with treads and a handrail before the next floor goes up.
Fall protection
A fall protection system is needed where a worker could fall 3 m or more, or less where landing would be worse than on a flat surface. Guardrails come first; then other fall restraint, then fall arrest or rope access, and only then work procedures WorkSafeBC accepts. Workers learn the area's system before they go in.
A written fall protection plan is on site before work begins where falls of 7.5 m or more are possible without permanent guardrails. Harnesses, lanyards and other fall protection equipment are inspected by a qualified person before use on each shift.
Excavations
Before anyone enters an excavation over 1.2 m deep, its sides are sloped, benched or supported with shoring or a trench box. Underground utilities are located before digging with powered equipment, an exit is within 8 m of workers in a trench over 1.2 m, and excavated material stays at least 60 cm back from a trench edge. Deep excavations, those next to structures and some others follow a qualified registered professional's written instructions kept at the site.
Common mistakes
- Working above 7.5 m without a written fall protection plan on site.
- Using a harness where a guardrail was practicable.
- Skipping the pre-shift inspection of fall protection gear.
- Sending a worker into a trench over 1.2 m before it is sloped or shored.
- No posted site drawing on a site with several employers.
