811 (call Before You Dig)

A provision in occupational health and safety legislation requiring employers to protect workers from recognised hazards, even when no specific regulation exists. For subcontractors, this means you can be cited for unsafe conditions on site regardless of client-controlled environments. It applies to your workers whether you own the worksite or not.

A U.S. pre-construction air permitting process triggered when new or modified industrial facilities exceed emissions thresholds. Subcontractors working on facility expansions or new builds may face project delays until NSR approval is granted. Understanding NSR timelines helps field crews anticipate mobilisation schedules on affected sites.

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.

A formal directive halting all or part of a worksite operation due to a safety, contractual, or regulatory concern. Subcontractors must comply immediately, regardless of who issues it. Downtime caused by a stop-work order may affect billing, crew scheduling, and contract timelines.

A non-destructive inspection method using X-rays or gamma rays to detect internal flaws in welds and pipework. Subcontractors must ensure certified RT technicians and proper radiation safety protocols are in place. Clients often require RT sign-off before authorising pressure testing or commissioning work.

A U.S.-based accreditation body that certifies crane operators through standardised written and practical exams. Many oil and gas and construction clients require NCCCO certification before allowing lift operations on site. Subcontractors must confirm their operators hold valid credentials to avoid mobilisation delays or contract disqualification.
