The cumulative sleep loss built up over successive long shifts or rotations. Workers carrying sleep debt show impaired judgement and slower reaction times. It is a recognised fatigue risk factor under worksite safety regulations.
Sleep Debt
Related Terms
Export Authorization
ComplianceA government-issued permit allowing equipment, technology, or services to be delivered across international borders. Subcontractors must secure this before mobilising tools or personnel to foreign project sites. Missing authorisation can halt operations and trigger costly delays.
CWSRF (Clean Water State Revolving Fund)
ComplianceA U.S. federal-state loan programme funding water infrastructure projects like treatment plants and pipelines. Subcontractors often bid on CWSRF-funded work, which carries strict Davis-Bacon wage and compliance requirements. Understanding funding sources helps field crews anticipate reporting obligations and payment timelines.
Hazardous Energy Isolation
ComplianceThe process of controlling dangerous energy sources—electrical, hydraulic, pneumatic, or mechanical—before maintenance or repair work begins. Subcontractors must follow the site owner's lockout/tagout (LOTO) procedures or risk losing site access. Non-compliance can void your contract and trigger serious liability.
Certified Payroll
ComplianceA government-required weekly payroll report proving workers were paid prevailing wages on publicly funded projects. Subcontractors must submit it to the prime contractor or project owner. Errors or late submissions can delay payment or trigger contract penalties.
PFAS (Per- and Polyfluoroalkyl Substances)
ComplianceA 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.
TRO (Temporary Restraining Order)
ComplianceA court order that immediately halts a specific action, such as work stoppage disputes or lien enforcement, pending a full hearing. Subcontractors may face a TRO if a general contractor seeks to block liens or contract terminations. It is a short-term legal tool, typically lasting days, until a judge rules further.
