Corrective Action Plan

The process by which operators and prime contractors vet subcontractors before awarding work. It typically involves reviewing insurance, safety records, certifications, and financial stability. Failing to qualify can bar a company from bidding on projects entirely.

A formal dispute filed against a customs ruling, such as import duties charged on tools or equipment crossing the border. Subcontractors use protests to recover overbilled duties on temporarily imported gear. Filing deadlines are strict, so act quickly after receiving a customs decision.

A toxic, flammable gas found on many oil and gas sites that poses serious health and safety risks to field workers. Subcontractors must ensure all personnel hold valid H2S Alive certification before mobilising to affected sites. Failure to comply can result in immediate removal from site and contract penalties.

A medical emergency caused by hanging motionless in a harness, restricting blood flow and leading to unconsciousness or death. Subcontractors working at height must plan for rapid rescue — OSHA and provincial regulations require it. Train crews to recognise symptoms and never leave a suspended worker unattended.

A regulatory approval issued by provincial authorities before drilling or completing a well can begin. Subcontractors should confirm a valid licence is in place before mobilising, as work cannot legally proceed without it. Delays in licensing directly affect your crew scheduling and contract start dates.

A formal process for documenting and approving any deviation from original scope, equipment, or procedures on a worksite. Subcontractors must follow the prime contractor's MOC process before making field changes. Skipping this step can void your contract or expose your crew to liability.
