DOE (Department of Energy)

A periodic federal renewal of legislation governing road, rail, and trucking regulations. For subcontractors, it can change load limits, hauling permits, and carrier compliance requirements. Review updates carefully, as new rules may affect equipment mobilisation costs and timelines.

A trained worker stationed outside a permit-required confined space to monitor entrants and conditions. They maintain communication with the entry team and initiate rescue procedures if hazards arise. Subcontractors must supply a qualified attendant or face work stoppages and liability on site.

A designated facility equipped with emergency response tools, breathing apparatus, and trained personnel for underground mine incidents. Subcontractors working on mining sites must know the nearest station location before starting work. Some contracts require your crew to complete mine rescue familiarisation training as a site entry condition.

A site-specific authorisation required before subcontractors can perform work at an owner-operated facility. It outlines approved work scopes, safety conditions, and access restrictions. Failing to secure one before mobilising can result in removal from site or contract penalties.

For subcontractors, an LOC incident can trigger immediate work stoppages, site investigations, and liability exposure. Proper reporting and response procedures are typically required under your prime contractor agreement.

A standards organisation that sets widely recognised specifications for materials, equipment, and testing procedures. Subcontractors must often meet ASTM standards when supplying materials or performing work on oil & gas and construction sites.
