Fixed Ladder
ComplianceA permanently mounted ladder attached to a structure, vessel, or facility used to access elevated work areas. Subcontractors must ensure fixed ladders on their worksites meet provincial and federal safety standards before crews use them. Inspect for damage, proper cage guards, and fall arrest anchor points before starting elevated work.
Psychological Safety
ComplianceA work environment where crew members feel safe to report hazards, mistakes, or concerns without fear of punishment or ridicule. For subcontractors, it reduces incident rates and improves site communication. Crews with high psychological safety are more likely to flag near-misses before they escalate.
Landfill Gas
ComplianceGas produced by decomposing waste in landfills, primarily methane and carbon dioxide. Subcontractors working near landfill sites must account for LFG (Landfill Gas) detection and ventilation requirements. Exposure risks and monitoring obligations affect site safety planning and PPE requirements.
Leading Indicators
ComplianceProactive metrics that signal future safety or performance issues before incidents occur. For subcontractors, these include near-miss reports, toolbox talk attendance, and equipment inspection rates. Tracking them helps crews stay ahead of problems rather than reacting after the fact.
FMCSA (Federal Motor Carrier Safety Administration)
ComplianceThe U.S. federal agency regulating commercial trucking and transportation safety. Subcontractors hauling equipment across the border or operating in the U.S. must comply with FMCSA rules. This includes driver logs, vehicle inspections, and carrier registration requirements.
Heat Stress
ComplianceA condition where the body cannot cool itself fast enough during hot or humid work conditions. It poses serious health and liability risks for subcontractors with outdoor or confined-space crews. Unmanaged heat stress can trigger site shutdowns and affect your compliance standing with the prime contractor.
