A substance or condition that can cause fire, explosion, or violent reaction when exposed to heat, air, water, or other chemicals. Subcontractors must identify these hazards during site orientations and follow the operator's safe handling procedures. Failure to do so can trigger immediate work stoppages or removal from site.
Reactive Hazard
Related Terms
SIF (Serious Injuries and Fatalities)
ComplianceA safety classification used by operators to track incidents resulting in death or life-altering harm. Subcontractors are often scored on SIF exposure and near-miss rates during prequalification. A high SIF risk profile can disqualify your company from site access or contract awards.
Caught-In Hazard
ComplianceA 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.
Api 653
ComplianceAPI 653 (American Petroleum Institute Standard 653) governs the inspection, repair, alteration, and reconstruction of above-ground storage tanks. Subcontractors performing tank work must comply with this standard or risk failed inspections and contract penalties. Many operators require certified API 653 inspectors on-site before authorising any tank maintenance scope.
811 (call Before You Dig)
ComplianceA free national service requiring subcontractors to notify utility companies before any ground disturbance. Utilities mark underground lines within 48–72 hours, reducing strike risk. Non-compliance can result in serious liability, fines, and project shutdowns.
Equivalency Agreement
ComplianceA formal arrangement where two jurisdictions recognise each other's safety training or certifications as mutually acceptable. For subcontractors, this means workers certified in one province or region can mobilise to another without repeating training. It reduces downtime and credentialing costs when moving crews across borders.
Local Content Requirement
ComplianceA contractual or regulatory rule requiring subcontractors to hire local workers, source materials locally, or partner with regional firms. Non-compliance can disqualify you from bidding or trigger contract penalties. Common on projects funded by governments or national oil companies.
