Compliance Glossary Term

Approved Vendor List

A client- or prime contractor-maintained registry of pre-qualified suppliers and subcontractors eligible to bid on work. Getting onto an AVL often requires submitting safety records, insurance, and certifications in advance. Without AVL status, subcontractors are typically blocked from receiving purchase orders or contracts.

Caught-In Hazard

Compliance

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.

Lead Service Line Replacement

Compliance

A regulated programme to remove and replace lead water pipes connecting mains to buildings. Subcontractors are often mobilised under municipal contracts to perform excavation, pipe removal, and restoration work. Compliance with environmental and safety regulations is mandatory throughout.

Lagging Indicators

Compliance

Metrics that measure past performance, such as recordable injuries, lost-time incidents, or missed deadlines. Subcontractors use them to identify trends after the fact. They appear frequently in client scorecards and prequalification reviews.

Utility Locate

Compliance

A pre-dig service that identifies and marks underground utilities before excavation begins. Subcontractors are typically required to obtain a locate before breaking ground. Failure to do so can result in liability for damages, project shutdowns, or regulatory fines.

Brackish Water

Compliance

Water with salinity between fresh water and seawater, commonly encountered during drilling or site dewatering operations. Subcontractors must handle it as a controlled substance — improper disposal can trigger environmental violations and project shutdowns. Verify disposal protocols with the prime contractor before mobilising.

Intrastate Pipeline

Compliance

A pipeline that operates entirely within one province or state, regulated by provincial or state authorities rather than federal bodies. Subcontractors must hold the correct provincial certifications and follow local codes when working on these systems. Permitting, inspections, and compliance requirements differ significantly from interprovincial lines.
