ComplianceFederal and provincial rules limiting methane emissions from oil and gas operations. Subcontractors must ensure equipment like compressors and pneumatic devices meets leak detection and repair standards. Non-compliance can result in work stoppages or contract termination.
Caught-In Hazard
ComplianceA workplace danger where a worker's body or clothing becomes trapped, pinched, or pulled into moving machinery, equipment, or materials — common on oilfield and construction sites where subcontractor crews work near rotating equipment, conveyor systems, or heavy moving loads. Subcontractors are responsible for identifying and controlling these hazards through proper guarding, lockout/tagout procedures, and site-specific hazard assessments before work begins.
Methane Emissions Inventory
ComplianceA documented record of all methane releases from equipment and operations on a worksite. Subcontractors may be required to contribute data or maintain their own inventory to meet operator or regulatory reporting obligations. Accurate records help avoid penalties and support contract compliance.
DBE (Disadvantaged Business Enterprise)

Prime contractors on federally funded projects often must subcontract a percentage of work to certified DBEs. Holding DBE status can open doors to set-aside contracts and preferred bidder programmes.
Barrier Envelope
ComplianceThe defined set of active safety barriers protecting against a specific hazard at any given time. Subcontractors must verify the envelope is intact before starting work. A degraded envelope requires stop-work action and notification to the prime contractor.
Eminent Domain
ComplianceA government's legal right to seize private land for public use, with compensation paid to owners. For subcontractors, it can trigger sudden project delays or site access changes. Always confirm right-of-way status before mobilising crews or equipment.
