The discipline focused on preventing uncontrolled releases of hazardous materials or energy that could cause fires, explosions, or toxic events. Subcontractors working near pressurised systems or chemicals must understand site-specific process hazards before starting work. Non-compliance can result in immediate removal from site and liability exposure.

Related Terms
PUCT (Public Utility Commission of Texas)
ComplianceTexas state agency that regulates electric, telecom, and water utilities. Subcontractors working on utility infrastructure projects in Texas must align with PUCT-governed standards and permitting. Non-compliance can delay project approvals and payment milestones.
Trenching Collapse
ComplianceA sudden cave-in of trench walls during excavation, posing serious injury or fatality risk to workers below grade. Subcontractors must ensure shoring, sloping, or trench box systems meet provincial OH&S requirements before crew entry. Liability for collapse incidents often falls on the excavating subcontractor, making documented safety compliance critical.
Prevailing Wage
ComplianceThe minimum hourly rate subcontractors must pay workers on government-funded projects, set by regional labour surveys. Rates vary by trade and location, directly affecting your bid pricing and labour costs. Underpaying prevailing wage on public contracts can result in fines, back pay obligations, and disqualification from future bids.
Carbon Intensity
ComplianceA measure of greenhouse gas emissions produced per unit of work or energy output. Operators increasingly require subcontractors to report and reduce carbon intensity on job sites. Lower scores can be a competitive advantage when bidding on contracts.
765-Kv Transmission
ComplianceUltra-high-voltage power lines used to move large amounts of electricity over long distances. Subcontractors working near these corridors face strict safety exclusion zones and specialised certification requirements. Crews must follow elevated electrical hazard protocols on any site within proximity.
Multi-Employer Worksite
ComplianceA site where two or more employers operate simultaneously, such as an owner, general contractor, and subcontractors. Each party carries shared safety obligations under provincial OHS legislation. Subcontractors must understand their specific duties and how site control affects liability.
