Mobile Equipment Near Ground Crews

Key Hazards

• Workers entering equipment blind spots
• Struck-by incidents from moving vehicles or machinery
• Communication failures between operators and ground crews

2–3 Minute Talk Script

Mobile equipment operating near ground crews creates serious hazards on construction sites, utility projects, municipal work zones, and industrial facilities. Excavators, loaders, dump trucks, forklifts, and service vehicles often work close to laborers, spotters, and pedestrians in constantly changing environments.

Equipment operators may have limited visibility due to blind spots, weather conditions, dust, noise, or surrounding structures. Ground workers should never assume operators can see them, especially when equipment is backing, turning, or swinging loads.

Different operations create different interaction hazards. Utility crews may work beside dump trucks or excavators in narrow roadways, municipal employees often operate around snowplows or loaders, and warehouse personnel may work near forklifts or delivery vehicles in congested areas.

Communication between operators and ground crews is critical. Spotters should remain visible at all times and use clear, agreed-upon signals. If visual contact is lost, equipment movement should stop immediately until communication is restored.

Changing ground conditions also increase hazards around mobile equipment. Mud, snow, uneven terrain, poor lighting, and tight work areas can reduce stopping ability and increase the risk of struck-by incidents. Workers should remain alert and avoid distractions while operating near moving machinery.

Safe work zones require separation whenever possible. Barriers, designated pedestrian routes, traffic control devices, and equipment staging plans help reduce dangerous interactions between workers and moving equipment.

Safety Reminders

• Never assume equipment operators can see you.
• Use spotters and agreed-upon hand signals when required.
• Stop equipment movement immediately if communication is lost.
• Stay clear of blind spots around moving equipment.
• Use barriers and designated walkways whenever possible.

Ask the Crew

• What equipment will be operating near ground crews today?
• Are spotters or barriers needed in active work areas?
• Do operators and ground crews understand the same hand signals?
• Are changing weather or ground conditions affecting visibility or traction?
