Working At Heights
ComplianceAny task performed at an elevation where a fall could cause injury, typically above 3 metres. Subcontractors must hold valid Working at Heights certification and comply with provincial OH&S regulations. Clients often require proof of training before allowing workers on site.
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.
Defense Production Act
ComplianceA U.S. federal law allowing the government to prioritise contracts and redirect materials to national security needs. Subcontractors may face supply chain delays or material shortages when it is invoked. Equipment and parts sourcing timelines can shift significantly with little notice.
API (American Petroleum Institute)

API certifications and compliance with API standards are often mandatory requirements in service contracts and can affect your ability to bid on projects.
Approved Vendor List
ComplianceA client- or prime contractor-maintained registry of pre-qualified suppliers and subcontractors eligible to bid on work. Getting onto an AVL often requires submitting safety records, insurance, and certifications in advance. Without AVL status, subcontractors are typically blocked from receiving purchase orders or contracts.
CUI (Controlled Unclassified Information)
ComplianceSensitive government or client data that requires protection but is not classified as secret. Subcontractors handling site plans, personnel records, or project specs may be legally required to safeguard CUI. Mishandling it can result in contract termination or regulatory penalties.
