Daily oil & gas and construction news for subcontractors

ComplianceGlossary Term

Utility Excavation

The process of digging near existing underground infrastructure such as gas lines, electrical conduits, or water mains. Subcontractors must locate and expose utilities safely before major earthworks begin. Requires ground disturbance permits and adherence to provincial Dig Safe or Click Before You Dig protocols.

Related Terms

LDAR (Leak Detection and Repair)

Compliance

A regulated programme requiring subcontractors to inspect equipment for fugitive emissions using specialised tools like optical gas imaging cameras. Findings must be documented and repaired within set timeframes under federal and provincial regulations. Field crews performing LDAR work often require specific training and certification to stay compliant on site.

National Emphasis Program (nep)

Compliance

A targeted OSHA enforcement initiative that focuses inspections on high-hazard industries or specific workplace dangers. Subcontractors in oil and gas or construction are frequently subject to NEP audits. Being on an active NEP site means heightened scrutiny of your crew's documentation, PPE, and safety procedures.

SDS (Safety Data Sheet)

Compliance

A standardised document detailing the hazards, handling requirements, and emergency procedures for a chemical or hazardous material. Subcontractors must keep current SDSs on-site for every controlled product their crew uses or transports. Inspectors and site safety officers can shut down work if SDSs are missing or outdated.

Leading Indicators

Compliance

Proactive metrics that signal future safety or performance issues before incidents occur. For subcontractors, these include near-miss reports, toolbox talk attendance, and equipment inspection rates. Tracking them helps crews stay ahead of problems rather than reacting after the fact.

ISEA (International Safety Equipment Association)

Compliance

A North American trade body that sets performance standards for personal protective equipment (PPE). Subcontractors should verify that hard hats, high-visibility vests, and eye protection meet ISEA standards. Many operator and general contractor safety plans require ISEA-compliant PPE on site.

Silica Disease

Compliance

An occupational lung illness caused by inhaling crystalline silica dust during drilling, sandblasting, or concrete work. Subcontractors must implement exposure controls and monitoring to meet regulatory requirements. Failure to protect workers can result in serious liability and lost contracts.
