Daily oil & gas and construction news for subcontractors

ComplianceGlossary Term

Energize

To bring electrical equipment or a system into a live, powered state on a job site. Subcontractors must confirm proper authorisation and lockout/tagout clearance before energizing any equipment. Premature energizing is a leading cause of worksite incidents and contractor liability.

Related Terms

Tier 2 Diesel Engine

Compliance

A diesel engine meeting EPA (Environmental Protection Agency) Tier 2 emissions standards, regulating nitrogen oxide and particulate output. Many job sites and municipalities restrict or ban Tier 2 equipment in favour of cleaner Tier 4 units. Subcontractors should verify equipment tier requirements before mobilising to avoid costly compliance issues or equipment swaps.

H2s (hydrogen Sulfide)

Compliance

A toxic, flammable gas found on many oil and gas sites that poses serious health and safety risks to field workers. Subcontractors must ensure all personnel hold valid H2S Alive certification before mobilising to affected sites. Failure to comply can result in immediate removal from site and contract penalties.

HAZOP (Hazard and Operability Study)

Compliance

A structured risk review that identifies hazards in a process or worksite before operations begin. Subcontractors are often required to participate or submit supporting documentation. Your crew's task-specific risks may be reviewed and built into site safety plans.

Acclimatization

Compliance

The process of allowing workers to safely adjust to extreme heat, cold, or altitude before full-duty deployment. Most worksites and safety regulations require a structured acclimatization period for new or returning crew. Subcontractors must factor this non-productive time into scheduling and labour costs.

Osha (occupational Safety and Health Administration) Variance

Compliance

A formal permit allowing a subcontractor to use an alternative method that differs from a standard OSHA regulation. It is granted when the alternative provides equal or greater worker protection. Subcontractors must apply directly and remain compliant with all variance conditions during field operations.

Re-Qualify

Compliance

The process of renewing or repeating required safety, technical, or vendor approvals after they have lapsed or been revoked. Operators and prime contractors may require subcontractors to re-qualify before awarding new work. Failing to re-qualify on time can result in removal from approved vendor lists.
