Preventing Struck-By Incidents
Overview
Struck-by incidents occur when workers are hit by moving objects, vehicles, equipment, or falling materials. These accidents cause serious injuries and fatalities but are largely preventable through awareness, proper procedures, and effective communication between workers and equipment operators.
Why This Is Important
Struck-by incidents can cause devastating injuries including broken bones, head trauma, internal injuries, and death. These accidents often happen suddenly, giving workers little time to react or escape. The combination of heavy equipment, elevated work, and multiple trades working in proximity creates numerous struck-by hazards.
Preventing struck-by incidents requires constant vigilance from all workers, clear communication protocols, and effective site management to separate workers from moving hazards whenever possible.
Best Practices & Safety Tips
High Visibility
Wear bright, high-visibility clothing and reflective gear to ensure equipment operators and other workers can see you clearly.
Use Spotters
Use trained spotters when working near moving equipment, especially during backing operations and in congested areas.
Barricade Areas
Establish and maintain barricades around hazardous operations to keep workers away from struck-by dangers.
Clear Communication
Maintain constant communication with equipment operators using hand signals, radios, or other approved methods.
Common Struck-By Hazards
Falling Objects
Materials dropped from height, inadequate securing, tool drops
Vehicle Strikes
Mobile equipment, delivery trucks, backing incidents
Swinging Objects
Crane loads, equipment counterweights, suspended materials
Flying Debris
Power tool discharge, compressed air, grinding sparks
Safety Procedures
Awareness & Position
- Stay clear of moving equipment, vehicles, and suspended loads at all times
- Position yourself where equipment operators can see you before starting work
- Keep tools, materials, and equipment organized to prevent them from becoming projectiles
- Never walk or work under suspended loads or in equipment swing areas
Site Management
- Secure loads properly during transport to prevent materials from shifting or falling
- Follow established site traffic control plans and designated walkways
- Report unsafe conditions, near-miss incidents, and struck-by hazards immediately
- Coordinate work activities to minimize conflicts between workers and equipment
Discussion Questions
- What struck-by hazards are present in your current work area that need attention?
- How do you maintain awareness of moving equipment and vehicles around you?
- What communication methods work best for coordinating with equipment operators?
- How can we improve barricading and exclusion zones around hazardous operations?
- What would you do if you witnessed a potential struck-by incident about to occur?
Action Items
- Verify all workers have appropriate high-visibility clothing
- Establish clear communication protocols with equipment operators
- Review and improve barricading procedures for hazardous operations
- Ensure spotters are trained and available for equipment operations
Takeaway: Preventing struck-by incidents requires constant awareness, clear communication, and proper procedures. Stay visible, stay alert, and maintain safe distances from moving equipment and materials. Remember - struck-by incidents happen quickly, so prevention is your best protection.
