Materials or conditions that can cause fires, explosions, or toxic releases through chemical reactions when exposed to heat, water, or other substances. Subcontractors must identify these hazards before work begins and follow site-specific handling protocols. Common examples in oilfield and construction work include peroxides, unstable gases, and certain drilling chemicals.
Reactive Hazards
Related Terms
Nfpa 70e (national Fire Protection Association 70e Standard for Electrical Safety in the Workplace)
ComplianceA U.S. standard governing electrical safety practices, PPE requirements, and arc flash hazard protocols on job sites. Subcontractors working on energised electrical systems must comply to meet site access and insurance requirements. Canadian contractors often encounter it on cross-border projects or with American general contractors.
HAZOP (Hazard and Operability Study)
ComplianceA 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.
Pattern of Violations
ComplianceA series of repeated safety or regulatory infractions flagged by inspectors or clients over time. For subcontractors, it signals systemic non-compliance and can trigger contract termination or disqualification from future bids. Regulators may impose escalating fines or mandatory audits based on documented patterns.
PSM (Process Safety Management)
ComplianceA regulatory framework governing hazardous process facilities like refineries and gas plants. Subcontractors working on-site must comply with the operator's PSM programme, including hazard reviews and safe work permits. Non-compliance can result in immediate removal from site.
Suspension Trauma
ComplianceA medical emergency caused by hanging motionless in a harness, restricting blood flow and leading to unconsciousness or death. Subcontractors working at height must plan for rapid rescue — OSHA and provincial regulations require it. Train crews to recognise symptoms and never leave a suspended worker unattended.
LFI (Learning From Incidents)
ComplianceA formal process where incident findings are shared across crews and job sites to prevent repeat occurrences. Subcontractors are often required by operators to distribute LFIs to their workforce and document acknowledgement. Failure to action LFIs can affect your standing on approved vendor lists.
