Daily oil & gas and construction news for subcontractors

ComplianceGlossary Term

Chain-Of-Custody

A documented record tracking who handled materials, samples, or equipment at every stage of a job. Subcontractors must maintain this trail to prove proper handling and avoid liability disputes. It is commonly required for soil samples, hazardous materials, and serialised equipment.

Related Terms

Intrastate Pipeline

Compliance

A pipeline that operates entirely within one province or state, regulated by provincial or state authorities rather than federal bodies. Subcontractors must hold the correct provincial certifications and follow local codes when working on these systems. Permitting, inspections, and compliance requirements differ significantly from interprovincial lines.

HAZOP (Hazard and Operability Study)

Compliance

A structured risk review that identifies hazards in a process or worksite before operations begin. Subcontractors are often required to participate or submit supporting documentation. Your crew's task-specific risks may be reviewed and built into site safety plans.

Hazard Orientation

Compliance

A mandatory site-specific safety briefing required before subcontractor crews begin work on a new location. It covers site-specific risks, emergency procedures, and restricted zones. Primes or operators typically deliver it, and subcontractors must document attendance for compliance.

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.

Nuclear Verdict

Compliance

A jury award so large it far exceeds actual damages, often driven by juror emotion rather than evidence. For subcontractors, even one such ruling can bankrupt a company or trigger uninsurable liability exposure. These verdicts are increasingly common in oilfield and construction injury cases.

NRC (Nuclear Regulatory Commission)

Compliance

A U.S. federal agency that regulates civilian nuclear facilities and materials. Subcontractors working near nuclear sites must meet strict NRC access and safety requirements. Non-compliance can result in immediate removal from site.
