Load Stability and Material Shift Hazards

• Loads shifting unexpectedly during movement or storage
• Crush and pinch injuries from unstable materials
• Loss of control caused by poor load balance or improper securement

Load stability and material shift hazards are common in construction sites, warehouses, utility operations, municipal facilities, and industrial work areas. Materials that appear stable may suddenly roll, slide, tip, collapse, or shift during lifting, transport, or staging operations.

Different operations create different material handling hazards. Utility crews often handle pipe, fittings, and heavy equipment components, warehouses manage stacked pallets and packaged materials, and construction sites regularly move irregular or oversized loads through active work areas.

Improper load balance and unstable center-of-gravity conditions increase the likelihood of shifting materials. Rolling pipe, leaning pallets, unsecured tools, suspended loads, and unevenly stacked materials can create sudden crush or struck-by hazards if movement occurs unexpectedly.

Workers should inspect loads before movement and verify that lifting points, straps, chains, pallets, and storage surfaces remain stable and rated for the intended load. Materials should be secured properly during transport and staged in areas where accidental contact or vibration will not cause shifting.

Body positioning is critical during material handling operations. Workers should avoid placing hands, feet, or body parts beneath suspended or unstable loads and remain alert for shifting conditions while lifting or maneuvering materials.

Communication becomes especially important during team lifting or equipment-assisted movement. Spotters, equipment operators, and ground personnel should maintain clear communication whenever visibility becomes limited or multiple workers are involved in moving materials.

• Inspect loads for stability before movement.
• Secure materials properly during transport and staging.
• Stay clear of suspended or shifting loads.
• Watch for rolling, leaning, or unstable materials.
• Maintain clear communication during lifting operations.

• Could any materials shift unexpectedly during today’s work?
• Are loads balanced and secured properly before movement?
• Do any staged materials create rolling or collapse hazards?
• Are communication procedures clear during lifting operations?
