Scope 1 covers direct emissions from equipment and vehicles your company owns or operates, such as diesel generators and fleet trucks. Scope 2 covers indirect emissions from purchased electricity used at your facilities or job sites. Prime contractors increasingly require subcontractors to track and report both when bidding on ESG-conscious projects.

Lagging Indicators
ComplianceMetrics that measure past performance, such as recordable injuries, lost-time incidents, or missed deadlines. Subcontractors use them to identify trends after the fact. They appear frequently in client scorecards and prequalification reviews.
National Emphasis Program (nep)
ComplianceA targeted OSHA enforcement initiative that focuses inspections on high-hazard industries or specific workplace dangers. Subcontractors in oil and gas or construction are frequently subject to NEP audits. Being on an active NEP site means heightened scrutiny of your crew's documentation, PPE, and safety procedures.
Energy Control Procedure
ComplianceA documented, step-by-step plan for isolating hazardous energy before subcontractors perform maintenance or service work. It outlines lockout/tagout steps specific to each piece of equipment on site. Subcontractors are typically required to follow or develop their own procedure that meets the site owner's standards.
Fatigue Risk Management
ComplianceA structured approach to identifying and controlling worker fatigue on job sites, especially during extended shifts or remote rotations. Subcontractors must often meet client FRM (Fatigue Risk Management) plans as a condition of site access. Failure to comply can result in removed personnel or contract termination.
Silica Disease
ComplianceAn occupational lung illness caused by inhaling crystalline silica dust during drilling, sandblasting, or concrete work. Subcontractors must implement exposure controls and monitoring to meet regulatory requirements. Failure to protect workers can result in serious liability and lost contracts.
Api 579
ComplianceAPI 579 (Fitness-For-Service) is an industry standard used to assess whether ageing or damaged equipment is safe to keep operating. Subcontractors may be required to support or comply with these assessments during inspection and maintenance scopes. Understanding it helps when working alongside integrity engineers on pressure vessels, piping, and tanks.
