The share of electrical capacity a subcontractor's site equipment or temporary facilities must supply during periods of maximum demand. Operators may contractually require field crews to manage or limit equipment startup times to avoid triggering peak load charges. Failing to comply can result in cost penalties passed down through the prime contractor.

A 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.

A 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.

A U.S. federal agency that regulates safety at mines and quarries. Subcontractors working on mine sites must comply with MSHA standards, separate from OSHA rules. Workers may require site-specific MSHA training before mobilising.

A pre-shift visual check of equipment, vehicles, or a worksite to identify hazards, damage, or defects before work begins. Subcontractors are typically required to document findings using a checklist. Incomplete or skipped inspections can create liability exposure and violate site safety requirements.

Personal protective equipment that stops a worker mid-fall before hitting a lower level or surface. Typically includes a full-body harness, lanyard, and anchor point. Subcontractors must ensure equipment is inspected, certified, and meets provincial OH&S regulations before workers use it on site.
