A regulatory document assessing a project's potential environmental effects before work can begin. Subcontractors must align their scope of work with EIS conditions or risk project delays and contract violations. Restrictions on equipment, timing, and site access are often tied directly to EIS approvals.
EIS (Environmental Impact Statement)
Related Terms
Confined Space Certification
ComplianceA mandatory credential confirming workers are trained to enter and work in enclosed or restricted areas such as tanks, vessels, or excavations. Subcontractors must hold valid certification before site access is granted on most oil and gas and construction projects. Expired certificates can result in worker removal, project delays, or contract penalties.
High-Energy Hazard
ComplianceAny source of stored or released energy that can cause serious injury or death, such as pressurised systems, suspended loads, or live electrical equipment. Subcontractors must identify these hazards before starting work and follow site-specific isolation procedures. Failure to control high-energy hazards is a leading cause of fatalities in oil and gas and construction environments.
FEMI (Fixed Equipment Mechanical Integrity)
ComplianceA systematic programme ensuring stationary assets like pressure vessels, piping, and heat exchangers remain safe and fit for service. Subcontractors often deliver FEMI work through inspection, NDT, and repair scopes under an owner's integrity management plan. Expect strict documentation requirements and third-party sign-off before returning equipment to service.
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.
Heat Index
ComplianceA measure combining air temperature and humidity to reflect how hot conditions actually feel to workers. Subcontractors use it to assess heat stress risk and trigger mandatory rest breaks or work stoppages. Most site safety plans reference heat index thresholds to stay compliant with occupational health regulations.
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.
