Engineered controls used to prevent cave-ins, collapses, or hazardous exposures at excavation and confined space sites. These include shoring, trench boxes, sloping, and shielding. Subcontractors are typically responsible for selecting and installing the correct system before work begins.
Protective Systems
Related Terms
S&S (Significant and Substantial)
ComplianceA regulatory classification used by MSHA to flag violations that could reasonably cause serious injury or illness. S&S citations carry higher fines and greater scrutiny for subcontractors working on mine sites. Accumulating S&S violations can jeopardise a subcontractor's site access and future contract eligibility.
LOTO (Lockout/tagout)
ComplianceA mandatory safety procedure requiring subcontractors to physically lock and label energy sources before servicing equipment. It prevents accidental startup during maintenance work. Site operators often require proof of worker LOTO certification before mobilisation.
Hazard Assessment
ComplianceA formal process where subcontractors identify and evaluate site-specific risks before work begins. It documents potential dangers, required controls, and responsible parties. Most client operators require a completed hazard assessment before issuing a work permit.
Indigenous Consultation
ComplianceA legal process where project proponents engage with Indigenous communities before work begins on or near their traditional lands. Subcontractors may need to pause or delay fieldwork if consultation requirements have not been met. Failing to respect this process can result in project shutdowns or permit rejections.
ROW (Right-of-way)
ComplianceA legally designated corridor of land where pipeline, power line, or infrastructure work is permitted to occur. Subcontractors must obtain ROW clearance before mobilising equipment or beginning ground disturbance. Working outside the approved ROW can trigger stop-work orders, fines, and contract liability.
Bonded Operator License
ComplianceA licence that requires the holder to carry a surety bond as financial assurance that they will meet regulatory obligations, meaning subcontractors and field service companies must maintain this bond coverage to legally operate certain equipment or perform specific scopes of work on a client's site. For subcontractors, holding a bonded operator licence is often a prerequisite for bidding on contracts, as it signals to operators and general contractors that financial accountability is in place if work standards or regulatory requirements are not met.
