The U.S. Navy agency that manages construction, facilities, and infrastructure contracts on military installations. Subcontractors working NAVFAC projects must meet strict security, compliance, and documentation requirements. Expect rigorous vetting, access protocols, and federally mandated labour standards on all NAVFAC job sites.

A standard governing process safety incident investigation in upstream oil and gas operations. Subcontractors may be required to follow its protocols when involved in a reportable incident on site. Familiarity with it helps field crews meet operator expectations during investigations.

Occurs when a subcontractor or field worker is incorrectly classified as an independent contractor instead of an employee. This exposes hiring companies to back-taxes, penalties, and liability for unpaid benefits. CRA audits in oil and gas and construction regularly target this issue.

A government or operator-imposed halt on specific activities, such as drilling or fracking, in a region. For subcontractors, this means work orders stop and contracts may be suspended without pay. Always review force majeure clauses before mobilising to areas under active moratorium discussions.

The controlled release of gases from pipelines, vessels, or equipment during maintenance, commissioning, or decommissioning work. Subcontractors must follow site-specific venting procedures to remain compliant with environmental and safety regulations. Improper venting can result in work stoppages, fines, or removal from site.

A struck-by hazard refers to any situation on a worksite where personnel risk injury from a moving object, such as swinging loads, dropped tools, vehicles, or pressurised line failures — a leading cause of fatality that subcontractors must identify and control in their site-specific hazard assessments and toolbox talks. For field service crews working around heavy equipment, cranes, or high-traffic laydown yards, recognising and mitigating struck-by risks is a core compliance obligation under provincial occupational health and safety legislation.
