Gas produced by decomposing waste in landfills, primarily methane and carbon dioxide. Subcontractors working near landfill sites must account for LFG (Landfill Gas) detection and ventilation requirements. Exposure risks and monitoring obligations affect site safety planning and PPE requirements.

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.

Formal approval granted by an oil and gas operator confirming a subcontractor meets their specific safety, training, and insurance standards. Without it, your crews cannot access the operator's sites or perform work. Certification requirements vary by operator and must be renewed regularly.

A medical emergency caused by hanging motionless in a harness, restricting blood flow and leading to unconsciousness or death.
