CBP (Customs and Border Protection)

A mandatory work stoppage called by a prime contractor or owner to address an immediate safety concern or incident. All field personnel halt operations and gather for a safety review before work resumes. Subcontractors must comply immediately, regardless of schedule or milestone pressures.

A series of repeated safety or regulatory infractions flagged by inspectors or clients over time. For subcontractors, it signals systemic non-compliance and can trigger contract termination or disqualification from future bids. Regulators may impose escalating fines or mandatory audits based on documented patterns.

Sensitive 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.

A formal written authorisation required before performing any work that produces heat, sparks, or open flame on a job site. Subcontractors must obtain this permit before welding, cutting, or grinding near flammable materials. Site supervisors issue and sign off on these permits, and work must stop if conditions change.

A U.S. federal law that grants the president broad authority to regulate or block international trade and financial transactions during a declared national emergency, which can directly affect subcontractors by triggering sudden tariffs on imported equipment and materials, disrupting cross-border project timelines, or restricting payments to and from American clients and primes. Field service companies working on U.S.-linked contracts or sourcing materials from affected countries should monitor IEEPA-related executive orders closely, as cost structures and contract terms can shift with little notice.

A struck-by hazard refers to any situation on a worksite where personnel risk injury from a moving object, such as swinging loads, dropped tools, vehicles, or pressurised line failures — a leading cause of fatality that subcontractors must identify and control in their site-specific hazard assessments and toolbox talks. For field service crews working around heavy equipment, cranes, or high-traffic laydown yards, recognising and mitigating struck-by risks is a core compliance obligation under provincial occupational health and safety legislation.
