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.
