RAGAGEP (Recognised and Generally Accepted Good Engineering Practices)

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.

A legal principle that assigns fault percentages to each party involved in an incident or loss. If a subcontractor is found partially at fault, their compensation can be reduced by their share of blame. Understanding this protects subcontractors from absorbing disproportionate liability on shared job sites.

A documented safety plan subcontractors must follow when performing any digging, trenching, or ground-breaking work on a job site. It outlines hazard assessments, soil classifications, protective systems, and entry protocols. Clients and prime contractors typically require proof of a compliant program before mobilisation.

A technique where certified technicians use ropes and harnesses to reach elevated or confined work areas without scaffolding. Common in tank inspections, flare stack maintenance, and structural repairs. Subcontractors must ensure crews hold valid IRATA or SPRAT certifications before mobilising.

A battery-powered respirator that uses a blower to push contaminated air through filters before the worker breathes it. Subcontractors working in refineries, confined spaces, or around hazardous chemicals are often required to supply their own PAPR units. Fit-testing and training records must be maintained to meet occupational health regulations on site.

Any part that contains or holds pressurised fluid, such as a valve, fitting, or vessel wall. Subcontractors handling these parts must meet strict inspection and certification requirements. Improper installation or repair can trigger liability, stop-work orders, or regulatory penalties.
