Reactive Hazards

A designation for positions where impairment could directly cause injury, death, or environmental harm. Common examples include equipment operators, riggers, and drivers. Workers in these roles are typically subject to mandatory drug and alcohol testing under client and regulatory requirements.

A group of synthetic chemicals found in firefighting foams, protective gear, and some industrial fluids used on job sites. Subcontractors may face handling restrictions, disposal requirements, and liability exposure under evolving federal and provincial regulations. Always check site-specific PFAS protocols before mobilising, as non-compliance can result in fines or contract termination.

A single compliance document covering multiple jobs or site visits within a set period, rather than issuing one per mobilisation. Common for insurance, tax exemption, or safety credentials. Reduces paperwork for subcontractors working repeat engagements with the same operator.

A designated worker assigned to monitor for fire or sparks during and after hot work operations like welding or grinding. Subcontractors are often required to supply certified firewatchers as a condition of their work permit. This role carries direct liability, so confirm scope and duration with the prime contractor before mobilising.

The U.S. OSHA excavation and trenching standard that subcontractors must follow on American job sites. It requires protective systems for any trench deeper than five feet. Non-compliance can result in stop-work orders, fines, and contract termination.

A U.S. federal agency that investigates industrial chemical accidents and releases public safety findings. Subcontractors working on cross-border or U.S.-linked projects should monitor CSB reports for lessons learned.
