Compliance Glossary Term

MRO (Medical Review Officer)

A licensed physician who reviews and verifies workplace drug test results before they are reported to an employer. Subcontractors must use an MRO-approved process to meet site access and compliance requirements. Failed or unverified MRO results can pull workers from the field immediately.

Related Terms

HOP (Human and Organizational Performance)

Compliance

A safety framework recognising that human error is normal and systems should be designed to reduce its impact. For subcontractors, HOP shifts blame away from individual workers toward process and organisational failures. Clients may require HOP-aligned incident reviews and pre-task planning on their worksites.

CCR (Coal Combustion Residuals)

Compliance

Solid and liquid waste materials produced by coal-fired power plants, including fly ash, bottom ash, and scrubber sludge. Subcontractors handling CCR sites must follow strict federal regulations governing storage, disposal, and remediation. Improper handling can trigger significant liability, so verify site-specific CCR compliance requirements before mobilising.

National Cosh (national Council for Occupational Safety and Health)

Compliance

A U.S.-based advocacy network pushing for stronger worker safety standards across industries, including oil and gas and construction. Subcontractors should monitor their policy campaigns, as recommendations often influence OSHA regulations affecting field operations. Their resources can help companies identify emerging compliance risks before they become enforceable requirements.

LOTO (Lockout/tagout)

Compliance

A mandatory safety procedure requiring subcontractors to physically lock and label energy sources before servicing equipment. It prevents accidental startup during maintenance work. Site operators often require proof of worker LOTO certification before mobilisation.

DBE (Disadvantaged Business Enterprise)

Compliance

A certification recognising businesses owned by minorities, women, or economically disadvantaged individuals. Prime contractors on federally funded projects often must subcontract a percentage of work to certified DBEs. Holding DBE status can open doors to set-aside contracts and preferred bidder programmes.

Exposure Profile

Compliance

A summary of the financial, safety, and liability risks a subcontractor faces on a given project or contract. It helps field service companies assess whether insurance coverage, bonding, and safety protocols are adequate. Reviewing your exposure profile before mobilising can prevent costly gaps in protection.
