Understanding and Preventing OSHA Struck-By Hazards in the Workplace

​Struck-by hazards represent one of OSHA's "Fatal Four" leading causes of workplace fatalities in construction, but they pose significant risks across all industries. Understanding these hazards and implementing proper safety measures can prevent serious injuries and save lives.

​What Are Struck-By Hazards?

​Struck-by injuries occur when a worker is hit by a moving object or piece of equipment. OSHA categorizes these hazards into four main types:

​1. Flying Objects

• Objects ejected from tools or machinery
• Particles and debris from grinding operations
• Uncoiled springs or tensioned materials
• Nail gun projectiles

​2. Falling Objects

• Tools dropped from heights
• Materials being moved overhead
• Unsecured loads
• Collapsing structures or equipment

​3. Swinging Objects

• Crane loads
• Materials being mechanically lifted
• Door or gate movements
• Construction materials during handling

​4. Rolling Objects

• Vehicles and heavy equipment
• Wheeled carts or containers
• Construction materials like pipes
• Runaway wheels or tires

Conclusion

​Struck-by hazards present significant risks in many workplaces, but they can be effectively managed through proper planning, training, and safety measures. By understanding these hazards and implementing comprehensive prevention strategies, organizations can protect their workers and maintain OSHA compliance.
