Heat Nep (heat National Emphasis Program)
ComplianceA targeted OSHA enforcement initiative directing inspectors to prioritise heat illness inspections at outdoor and indoor worksites. Subcontractors in oil & gas and construction face heightened scrutiny of heat safety plans, water access, and worker training. Non-compliance can trigger citations, fines, and work stoppages.
EMR (Experience Modification Rate)
ComplianceA numerical score calculated by insurers that compares your company's workplace injury claims to industry averages. A score below 1.0 indicates a safer-than-average record; above 1.0 signals higher risk. Many prime contractors and operators require subcontractors to maintain a low EMR to qualify for bid lists.
Fitness-For-Service (ffs)
ComplianceA formal engineering assessment that determines whether aging or damaged equipment is safe to keep operating. Subcontractors may be required to conduct or document FFS evaluations before resuming work on pressure vessels, pipelines, or structural components. Results directly affect your scope of work, liability exposure, and project timelines.
Eminent Domain
ComplianceA government's legal right to seize private land for public use, with compensation paid to owners. For subcontractors, it can trigger sudden project delays or site access changes. Always confirm right-of-way status before mobilising crews or equipment.
FERC (Federal Energy Regulatory Commission)
ComplianceThe U.S. federal body that regulates interstate energy infrastructure, including pipelines and transmission lines. Projects requiring FERC approval often have strict compliance timelines that affect subcontractor scheduling and scope. Work on FERC-regulated assets may require additional permitting and documentation.
S&S (Significant and Substantial)
ComplianceA 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.
