A formal written authorisation required before performing any work that produces heat, sparks, or open flame on a job site. Subcontractors must obtain this permit before welding, cutting, or grinding near flammable materials. Site supervisors issue and sign off on these permits, and work must stop if conditions change.

Related Terms
Flaring
ComplianceThe controlled burning of excess natural gas at a wellsite or facility. Subcontractors working on-site must follow strict flaring protocols, as ignition hazards affect work permits and safety zones. Flaring activity can also trigger regulatory hold points that delay field operations.
FAR (Federal Acquisition Regulation)
ComplianceThe FAR governs purchasing rules for U.S. federal contracts, including subcontractor requirements on government-funded projects. If your prime contractor holds a federal contract, FAR clauses flow down and bind your work. These rules cover pricing, record-keeping, audits, and labour standards you must follow.
MSHA (Mine Safety and Health Administration)
ComplianceA U.S. federal agency that regulates safety at mines and quarries. Subcontractors working on mine sites must comply with MSHA standards, separate from OSHA rules. Workers may require site-specific MSHA training before mobilising.
Crystalline Silica Rule
ComplianceA regulatory standard requiring subcontractors to limit worker exposure to airborne silica dust on worksites. Common in drilling, sandblasting, and concrete cutting operations. Requires action plans, air monitoring, and respirator programmes for affected crews.
Discovery Window
ComplianceThe limited timeframe in which a subcontractor can identify and formally report hidden site conditions that differ from the original contract scope. Missing this window typically voids your right to claim additional compensation or schedule relief. Review your contract carefully — discovery windows can be as short as 24 to 72 hours after encountering the condition.
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.
