National Cosh (national Council for Occupational Safety and Health)

A documented safety plan requiring subcontractors to manage worker exposure to extreme heat on jobsites. It typically covers hydration protocols, work-rest cycles, and heat acclimatisation schedules. Clients and prime contractors often require proof of a compliant program before mobilisation.

Inspection methods used to evaluate welds, pipelines, and structures without damaging them. Common NDT techniques include ultrasonic, radiographic, and magnetic particle testing. Subcontractors often need certified NDT technicians on crew to meet client and regulatory requirements.

A government-issued dig permit confirming underground utilities have been located and marked before excavation begins. Subcontractors must obtain one before any ground-disturbance work. Operating without one exposes your crew to liability, fines, and project shutdowns.

API RP 571 (Recommended Practice 571) identifies damage mechanisms affecting fixed equipment in refining and petrochemical facilities. Subcontractors performing inspection, maintenance, or repair work must understand these mechanisms to meet client integrity requirements. Familiarity with this standard is often required for turnaround and vessel entry scopes.

The U.S. federal standard governing excavation and trenching safety on construction sites. Subcontractors must comply with shoring, sloping, and protective system requirements before workers enter any excavation. Non-compliance can result in stop-work orders, fines, and loss of site access.

A site-specific authorisation required before subcontractors can perform work at an owner-operated facility. It outlines approved work scopes, safety conditions, and access restrictions. Failing to secure one before mobilising can result in removal from site or contract penalties.
