The ability of a well to contain fluids and pressure without uncontrolled release. Subcontractors performing wellsite work must follow strict well integrity protocols to prevent blowouts or leaks. Failure to comply can result in contract termination and regulatory penalties.

A workplace danger where a worker's body or clothing becomes trapped, pinched, or pulled into moving machinery, equipment, or materials — common on oilfield and construction sites where subcontractor crews work near rotating equipment, conveyor systems, or heavy moving loads. Subcontractors are responsible for identifying and controlling these hazards through proper guarding, lockout/tagout procedures, and site-specific hazard assessments before work begins.

A formal directive halting all or part of a worksite operation due to a safety, contractual, or regulatory concern. Subcontractors must comply immediately, regardless of who issues it. Downtime caused by a stop-work order may affect billing, crew scheduling, and contract timelines.

Subcontractors must log these incidents and report them to the prime contractor. High recordable rates can disqualify your company from future bids or vendor pre-qualification lists.

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.
