A site where two or more employers operate simultaneously, such as an owner, general contractor, and subcontractors. Each party carries shared safety obligations under provincial OHS legislation. Subcontractors must understand their specific duties and how site control affects liability.
Multi-Employer Worksite
Related Terms
CPWR (Centre for Construction Research and Training)
ComplianceA U.S.-based non-profit that develops safety research, training materials, and hazard guides used widely across North American job sites. Subcontractors often reference CPWR toolbox talks and fall protection resources to meet compliance requirements. Their free publications can support your crew orientations and site safety plans.
PIT (Powered Industrial Truck)
ComplianceAny motorised vehicle used to move materials on a worksite, including forklifts, reach trucks, and pallet jacks. Subcontractors operating PITs must ensure operators hold valid, site-accepted certifications. Non-compliance can trigger work stoppages or removal from site.
DOE (Department of Energy)
ComplianceA U.S. federal agency that regulates energy production, sets safety standards, and oversees projects involving nuclear, fossil fuel, and renewable energy. Subcontractors working on DOE-funded or DOE-regulated sites must meet strict compliance and security requirements. Contracts tied to DOE projects often include additional reporting obligations and certified personnel requirements.
Flaring
ComplianceThe controlled burning of excess natural gas at a wellsite or facility. Subcontractors working on-site must follow strict flaring protocols, as ignition hazards affect work permits and safety zones. Flaring activity can also trigger regulatory hold points that delay field operations.
Duty of Care
ComplianceA legal obligation requiring subcontractors to take reasonable steps to protect workers, clients, and the public from harm. It applies on-site, during travel, and in remote or hazardous work environments. Failing this duty can result in liability claims, lost contracts, or regulatory penalties.
Data Ownership
ComplianceData ownership defines who legally controls field data collected during a job — such as inspection reports, equipment readings, or site photos. Contracts often assign ownership to the client, limiting a subcontractor's right to reuse or retain that data. Review ownership clauses carefully before signing to protect your company's records and liability position.
