Environmental Review

A sudden cave-in of trench walls during excavation, posing serious injury or fatality risk to workers below grade. Subcontractors must ensure shoring, sloping, or trench box systems meet provincial OH&S requirements before crew entry. Liability for collapse incidents often falls on the excavating subcontractor, making documented safety compliance critical.

An accidental hit to a buried line — gas, electric, telecom, or water — during excavation or drilling. Subcontractors are typically liable for damages, work stoppages, and injuries if proper locates weren't completed. Always confirm valid BC One Call or Alberta One-Call tickets before breaking ground.

A struck-by hazard refers to any situation on a worksite where personnel risk injury from a moving object, such as swinging loads, dropped tools, vehicles, or pressurised line failures — a leading cause of fatality that subcontractors must identify and control in their site-specific hazard assessments and toolbox talks. For field service crews working around heavy equipment, cranes, or high-traffic laydown yards, recognising and mitigating struck-by risks is a core compliance obligation under provincial occupational health and safety legislation.

A contained, lined pit or pond used to collect, store, or treat liquid waste on a work site. Subcontractors working near these structures must follow strict handling and access protocols. Improper interaction with surface impoundments can trigger environmental compliance violations and halt operations.

When a prime contractor or client demands excessive paperwork and box-ticking that looks rigorous but adds no real safety value. Subcontractors absorb the administrative burden without reduced liability or improved site outcomes. Recognising it helps crews push back on busy-work that pulls focus from genuine hazard control.

The U.S. federal agency overseeing offshore energy leasing on the Outer Continental Shelf. Subcontractors working U.S. offshore projects must meet BOEM-driven compliance requirements set by their prime contractors. Permits and operational approvals from BOEM directly affect project timelines and mobilisation schedules.
