Exposing Employer
ComplianceThe company that directly exposes workers to a hazard on a multi-employer worksite, such as a subcontractor whose crew creates a fall risk. Under Canadian OHS regulations, the exposing employer holds primary responsibility for controlling that hazard. Subcontractors must understand this designation, as it determines who is liable for corrective action.
Pre-Qualification
ComplianceA vetting process where operators assess a subcontractor's safety record, insurance, and certifications before awarding work. Companies must meet minimum standards to be added to an approved vendor list. Failing pre-qualification means being locked out of bidding opportunities entirely.
Tunnel Ventilation
ComplianceA system that controls airflow in enclosed underground worksites to remove hazardous gases, dust, and fumes. Subcontractors must verify ventilation meets regulatory standards before crews enter. Inadequate ventilation can trigger work stoppages and liability for prime contractors.
Reclamation
ComplianceThe process of restoring a work site to its original or agreed-upon condition after project completion. Subcontractors are often scoped for reclamation work including grading, revegetation, and soil remediation. Reclamation scopes are regulated and must meet provincial closure criteria before sign-off.
Soil Classification
ComplianceA system for categorising ground conditions by type, stability, and load-bearing capacity. Subcontractors use it to determine excavation methods, shoring requirements, and equipment suitability. Misreading soil class can trigger safety violations or costly project delays.
Worksite Enforcement
ComplianceThe active monitoring and enforcement of safety, regulatory, and contractual rules on a job site. For subcontractors, non-compliance can result in stop-work orders, fines, or contract termination. Prime contractors typically hold enforcement authority over all subs on site.
