What Are Struck-By Incidents?

Struck-by incidents occur when a worker is hit by a moving object—such as tools, vehicles, equipment, or debris. These events are one of the leading causes of injury and death on construction sites and can happen in a split second without warning.

Examples of Struck-By Hazards

• Falling tools or materials from heights.
• Being hit by moving vehicles or equipment (e.g., forklifts, excavators).
• Flying particles from grinding, cutting, or power tools.
• Unsecured loads during rigging or lifting operations.
• Swinging or collapsing structures like crane arms or scaffold pieces.

How to Prevent Struck-By Incidents

• Wear appropriate PPE, including hard hats, high-vis vests, and safety eyewear.
• Secure all tools and materials when working at heights.
• Keep clear of operating machinery and marked exclusion zones.
• Inspect rigging and lifting equipment before use.
• Use spotters when backing or maneuvering equipment.
• Follow signage, barricades, and site traffic plans.
