TRIIPP (Temperature-related Injury and Illness Prevention Plan)

A U.S.-based non-profit that develops technical standards and research for the electric power industry. Subcontractors working on utility or power infrastructure projects may need to follow EPRI guidelines for equipment and installations. Their published standards can affect inspection, testing, and compliance requirements on job sites.

The process of renewing or repeating required safety, technical, or vendor approvals after they have lapsed or been revoked. Operators and prime contractors may require subcontractors to re-qualify before awarding new work. Failing to re-qualify on time can result in removal from approved vendor lists.

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.

Legally required costs to decommission and remediate a site at end of life, such as plugging wells or removing infrastructure.

Understand how ARO timelines affect contract scope, since decommissioning work often has strict regulatory deadlines.

A formal arrangement where two jurisdictions recognise each other's safety training or certifications as mutually acceptable. For subcontractors, this means workers certified in one province or region can mobilise to another without repeating training. It reduces downtime and credentialing costs when moving crews across borders.

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.
