A regulatory classification used by MSHA to flag violations that could reasonably cause serious injury or illness. S&S citations carry higher fines and greater scrutiny for subcontractors working on mine sites. Accumulating S&S violations can jeopardise a subcontractor's site access and future contract eligibility.
S&S (Significant and Substantial)
Related Terms
Indigenous Consultation
ComplianceA legal process where project proponents engage with Indigenous communities before work begins on or near their traditional lands. Subcontractors may need to pause or delay fieldwork if consultation requirements have not been met. Failing to respect this process can result in project shutdowns or permit rejections.
Alternative Risk Transfer
ComplianceART (Alternative Risk Transfer) covers non-traditional risk financing options outside standard insurance, such as captives or self-insurance pools. Subcontractors use ART programmes to manage liability exposure when conventional coverage is unavailable or too costly. Common in high-hazard field operations where standard insurers may decline coverage.
ROW (Right-of-way)
ComplianceA legally designated corridor of land where pipeline, power line, or infrastructure work is permitted to occur. Subcontractors must obtain ROW clearance before mobilising equipment or beginning ground disturbance. Working outside the approved ROW can trigger stop-work orders, fines, and contract liability.
Approved Vendor List
ComplianceA client- or prime contractor-maintained registry of pre-qualified suppliers and subcontractors eligible to bid on work. Getting onto an AVL often requires submitting safety records, insurance, and certifications in advance. Without AVL status, subcontractors are typically blocked from receiving purchase orders or contracts.
Walking-Working Surfaces Standard
ComplianceA regulatory standard governing slip, trip, and fall hazards on job sites. Subcontractors must ensure floors, platforms, ladders, and elevated surfaces meet inspection and guarding requirements. Non-compliance can result in stop-work orders or liability exposure on client sites.
Compliance Theater
ComplianceWhen a prime contractor or owner requires paperwork and box-checking that looks rigorous but adds no real safety value. Subcontractors absorb the administrative burden without reducing on-site risk. Recognising it helps crews push back on inefficiencies that drain time and resources.
