PUCO (Public Utilities Commission of Ohio)

A U.S. federal agency that manages public lands and issues permits for oil, gas, and construction operations on those lands. Subcontractors working on BLM-administered land must comply with specific permit conditions, environmental rules, and access requirements. Non-compliance can result in work stoppages or contract 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 U.S. standard governing electrical safety practices, PPE requirements, and arc flash hazard protocols on job sites. Subcontractors working on energised electrical systems must comply to meet site access and insurance requirements. Canadian contractors often encounter it on cross-border projects or with American general contractors.

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.

Legal responsibility for damages or injuries regardless of fault or negligence. Subcontractors can be held liable even if they followed all safety protocols. Common in environmental incidents and hazardous operations on job sites.

Scope 1 covers direct emissions from equipment and vehicles your company owns or operates, such as diesel generators and fleet trucks. Scope 2 covers indirect emissions from purchased electricity used at your facilities or job sites. Prime contractors increasingly require subcontractors to track and report both when bidding on ESG-conscious projects.
