Traffic Control Plan

California's state workplace safety regulator, enforcing standards that often exceed federal OSHA requirements. Subcontractors working on California job sites must comply with Cal/OSHA rules, not just federal ones. Non-compliance can result in fines, stop-work orders, and disqualification from future contracts.

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.

The share of electrical capacity a subcontractor's site equipment or temporary facilities must supply during periods of maximum demand. Operators may contractually require field crews to manage or limit equipment startup times to avoid triggering peak load charges. Failing to comply can result in cost penalties passed down through the prime contractor.

A government-imposed cost on greenhouse gas emissions, typically applied per tonne of CO2 equivalent. Subcontractors may face carbon charges on fuel, equipment operation, and fleet usage. These costs can affect project bids and operating margins if not factored into quotes.

A U.S. federal agency that regulates safety at mines and quarries. Subcontractors working on mine sites must comply with MSHA standards, separate from OSHA rules. Workers may require site-specific MSHA training before mobilising.

The FAR governs purchasing rules for U.S. federal contracts, including subcontractor requirements on government-funded projects. If your prime contractor holds a federal contract, FAR clauses flow down and bind your work. These rules cover pricing, record-keeping, audits, and labour standards you must follow.
