EMR (Experience Modification Rate)

A risk-based inspection standard used on oil and gas facilities to prioritise equipment checks by failure likelihood and consequence. Subcontractors may need to align their inspection scopes and documentation to meet API 580 requirements on client sites.

The company that directly exposes workers to a hazard on a multi-employer worksite, such as a subcontractor whose crew creates a fall risk. Under Canadian OHS regulations, the exposing employer holds primary responsibility for controlling that hazard. Subcontractors must understand this designation, as it determines who is liable for corrective action.

Rules set by governments or project owners requiring a minimum percentage of local labour, materials, or services on a contract. Subcontractors must demonstrate compliance through hiring records and procurement documentation. Failing to meet thresholds can disqualify your bid or trigger contract penalties.

Water extracted from the ground alongside oil and gas during production. Subcontractors handling, transporting, or disposing of it must meet strict environmental regulations. Improper management can trigger fines and halt site operations.

The U.S. federal agency that regulates the entry of workers, equipment, and materials across the Canadian-American border, which subcontractors must navigate when mobilising crews or hauling specialised equipment into U.S. job sites. Non-compliance with CBP requirements can result in delays at the border, seized equipment, or crews being turned away, making proper documentation and advance planning critical for cross-border field work.

A workplace danger where a worker's body or clothing becomes trapped, pinched, or pulled into moving machinery, equipment, or materials — common on oilfield and construction sites where subcontractor crews work near rotating equipment, conveyor systems, or heavy moving loads. Subcontractors are responsible for identifying and controlling these hazards through proper guarding, lockout/tagout procedures, and site-specific hazard assessments before work begins.
