CEM (Continuous Emissions Monitoring)

A documented record of all methane releases from equipment and operations on a worksite. Subcontractors may be required to contribute data or maintain their own inventory to meet operator or regulatory reporting obligations. Accurate records help avoid penalties and support contract compliance.

Federal legislation protecting at-risk wildlife and their habitats from project-related disturbance. Subcontractors working near designated critical habitat may face work stoppages, seasonal restrictions, or mandatory wildlife surveys. Non-compliance can halt projects and expose crews to significant fines.

A provision in occupational health and safety legislation requiring employers to protect workers from recognised hazards, even when no specific regulation exists. For subcontractors, this means you can be cited for unsafe conditions on site regardless of client-controlled environments. It applies to your workers whether you own the worksite or not.

The ASME (American Society of Mechanical Engineers) code governing the design, fabrication, and inspection of pressure vessels. Subcontractors working on pressure vessels must ensure equipment bears the ASME stamp, confirming code compliance. Non-compliant vessels can trigger work stoppages and liability issues on site.

API 653 (American Petroleum Institute Standard 653) governs the inspection, repair, alteration, and reconstruction of above-ground storage tanks. Subcontractors performing tank work must comply with this standard or risk failed inspections and contract penalties. Many operators require certified API 653 inspectors on-site before authorising any tank maintenance scope.

A U.S.-based non-profit that develops safety research, training materials, and hazard guides used widely across North American job sites. Subcontractors often reference CPWR toolbox talks and fall protection resources to meet compliance requirements. Their free publications can support your crew orientations and site safety plans.
