Nfpa 70e (national Fire Protection Association 70e Standard for Electrical Safety in the Workplace)

A regulatory requirement mandating fit-tested respirators and written programmes when workers face airborne hazards like H2S, silica, or fumes. Subcontractors must maintain records of fit tests, training, and equipment inspections for each worker. Non-compliance can result in stop-work orders or disqualification from site.

A legal finding that two companies share employer responsibilities over the same workers. In field service, this can mean a client company is liable for your crew's wages, hours, or working conditions. Subcontractors should review contracts carefully to avoid unintended joint employer exposure.

A court order from a provincial or state government that halts work on a project or site. Subcontractors must stop operations immediately or risk legal penalties. This can freeze contracts, delay payments, and strand mobilised crews and equipment.

A work environment where crew members feel safe to report hazards, mistakes, or concerns without fear of punishment or ridicule. For subcontractors, it reduces incident rates and improves site communication. Crews with high psychological safety are more likely to flag near-misses before they escalate.

A crane operator who holds recognised certification confirming competency to safely operate lifting equipment on job sites. Most oil & gas and construction contracts require subcontractors to supply CCO-certified operators. Verify certification currency before mobilisation, as expired credentials can halt work and trigger compliance penalties.

A 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.
