Daily oil & gas and construction news for subcontractors

ComplianceGlossary Term

Ladder Safety System

A fixed assembly of rails, brackets, and a climbing sleeve that prevents a worker from falling off a vertical ladder. Subcontractors are often required to install or inspect these systems before crews access elevated structures. Compliance with provincial fall-protection codes is typically a condition of site entry.

Related Terms

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The process of renewing or repeating required safety, technical, or vendor approvals after they have lapsed or been revoked.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.

Safety-Critical Roles

Compliance

Positions where errors or unqualified personnel can directly cause injury, fatality, or major incident on a worksite. Common examples include H2S monitors, crane operators, and confined space attendants. Subcontractors must verify certifications and competency before placing workers in these roles.

Permit Filings

Compliance

Official documentation submitted to regulatory bodies before starting work on a site. Subcontractors may be responsible for obtaining specific trade or activity permits. Delays in filings can halt work and affect project timelines and invoicing.

High-Energy Hazard

Compliance

Any source of stored or released energy that can cause serious injury or death, such as pressurised systems, suspended loads, or live electrical equipment. Subcontractors must identify these hazards before starting work and follow site-specific isolation procedures. Failure to control high-energy hazards is a leading cause of fatalities in oil and gas and construction environments.

JHA (Job Hazard Analysis)

Compliance

A written document identifying hazards and controls for a specific task before work begins. Subcontractors are typically required to complete and submit JHAs to the prime contractor or site owner. Failure to have a compliant JHA on site can result in work stoppages or disqualification from bidding.

ARO (Asset Retirement Obligations)

Compliance

Legally required costs to decommission and remediate a site at end of life, such as plugging wells or removing infrastructure. Operators budget ARO years in advance, which can create late-project work opportunities for subcontractors. Understand how ARO timelines affect contract scope, since decommissioning work often has strict regulatory deadlines.
