What are the primary hazards of a suspended load and how can you mitigate them?

• A. Electrical shock from overhead lines
• B. Struck-by and crush hazards from swinging or falling loads; mitigate with exclusion zones, clear communication, tag lines, slow controlled movements, and proper rigging and kill-switch procedures.
• C. Noise
• D. Temperature

Answer: (B)

When a load is suspended, the primary danger is that it can swing or fall and strike or crush workers. The load’s motion can be unpredictable due to wind, operator input, or rigging issues, making anyone within the load’s swing or drop zone vulnerable. The most effective mitigation focuses on controlling that risk.

Create an exclusion zone so no one stands where the load could reach if it swings or drops. Clear, precise communication among everyone involved ensures coordinated actions and prevents surprises. Tag lines give a physical means to guide and stabilize the load from a safe distance, reducing uncontrolled movement. Move the load slowly and with smooth, deliberate motions to minimize inertia and sway, giving people time to react and increasing overall control. Use proper rigging and lifting procedures so the load is secure and balanced; poor rigging can cause shifting, unpredictable swing, or a sudden drop. Having kill-switch procedures in place allows the operator to stop all motion immediately if something goes wrong.

Electrical, noise, or temperature hazards can be present in the work environment, but the most direct hazards from a suspended load are being struck by or crushed by the moving or falling load, and the mitigation steps above are specifically designed to address that risk.
