Compliance Glossary Term

Ladder Safety System

A fixed assembly of rails, brackets, and a climbing sleeve that prevents a worker from falling off a vertical ladder. Subcontractors are often required to install or inspect these systems before crews access elevated structures. Compliance with provincial fall-protection codes is typically a condition of site entry.

Related Terms

Prequalification

Compliance

A vetting process where operators assess a subcontractor's safety record, insurance, and certifications before awarding work. Companies must pass prequalification to be added to an approved vendor list. Failing or lapsing can disqualify a subcontractor from bidding on projects entirely.

Management of Change

Compliance

A formal process for documenting and approving any deviation from original scope, equipment, or procedures on a worksite. Subcontractors must follow the prime contractor's MOC process before making field changes. Skipping this step can void your contract or expose your crew to liability.

PSC (Public Service Commission)

Compliance

A provincial regulatory body that oversees public utilities and energy services in its jurisdiction. Subcontractors working on regulated utility projects must ensure their work meets PSC standards and approvals. Non-compliance can delay project sign-off and affect payment milestones.

811 (one-Call System)

Compliance

A mandatory pre-dig notification service subcontractors must contact before any ground disturbance work. It triggers utility locates to mark buried lines, protecting crews from strikes. Failure to call can result in fines, liability, and project shutdowns.

Hazard Assessment

Compliance

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.

Caught-In Hazard

Compliance

A 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.
