The restricted, secured zone of an airport beyond passenger screening. Subcontractors working airside — such as fuelling crews or ground maintenance teams — must hold valid airside passes and follow strict security protocols. Access is tightly controlled and non-compliance can result in immediate removal from site.

Legally required costs to decommission and remediate a site at end of life, such as plugging wells or removing infrastructure. Operators budget ARO years in advance, which can create late-project work opportunities for subcontractors. Understand how ARO timelines affect contract scope, since decommissioning work often has strict regulatory deadlines.

Any motorised vehicle used to move materials on a worksite, including forklifts, reach trucks, and pallet jacks. Subcontractors operating PITs must ensure operators hold valid, site-accepted certifications. Non-compliance can trigger work stoppages or removal from site.

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 formal system for isolating and de-energising equipment before maintenance or repair work begins. For subcontractors, this typically means following a client's lockout/tagout (LOTO) programme on site. Non-compliance can result in work stoppages, contract termination, or serious injury.

Protective gear — such as hard hats, steel-toed boots, high-visibility vests, gloves, and eye protection — that subcontractors and their crews are required to wear on oil & gas and construction sites to meet site-specific safety standards and regulatory obligations. As a subcontractor, ensuring your workers arrive on-site with proper, compliant PPE is typically your responsibility and a condition of maintaining your contract.
