Federal Highway Authorization

A deliberate breach of a safety regulation or worksite rule, where the subcontractor knew the requirement and chose to ignore it. Regulators treat these far more severely than accidental non-compliance. Fines, stop-work orders, or contract termination can follow.

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 Inspectors and site safety officers can shut down work if SDSs are missing or outdated.

The process of identifying and marking underground utilities before excavation begins. Subcontractors are often required to confirm locates are valid before breaking ground. Failure to comply can result in strikes, liability, and work stoppages.

An unplanned release of a hazardous substance — liquid, gas, or solid — from piping, vessels, or equipment. For subcontractors, an LOC incident can trigger immediate work stoppages, site investigations, and liability exposure. Proper reporting and response procedures are typically required under your prime contractor agreement.

The maximum airborne concentration of a hazardous substance a worker can be exposed to safely during a shift. Subcontractors must verify TLVs for chemicals and gases on site before mobilising crews. Exceeding TLVs without proper controls can trigger work stoppages and regulatory violations.

A data-driven system that analyses historical incident and near-miss records to forecast safety risks before they occur on site. Subcontractors may be required to feed worker hours, incident logs, and hazard reports into a client's PSAF platform. Compliance with PSAF reporting requirements is often tied to contract eligibility and site access approval.
