Struck-By Rolling Objects

Struck-by rolling object is when an object is rolling, moving, or sliding on the same level at which the worker is located.

Working around traffic is extremely dangerous.

It includes instances in which the worker is struck or run over by a moving vehicle without being caught under it or instances in which the worker is struck-by a sliding object or equipment on the same level.

Examples

  • While walking along the track, a worker was struck by an unmanned rail car at an airport.
  • A worker (security guard) was struck by a tractor trailer and dragged, resulting in fatal injuries.
  • A worker suffered fatal injuries after being struck by a moving semi-truck while loading/unloading freight.
  • A worker was performing repair operations on an impact attenuator and was struck by a truck.
  • A worker was flagging traffic and was struck by a truck.
  • A four-person ground crew was working with a mobile under-hung bridge crane. The crane ran over one of the crew members, who had walked too close to the wheel of the crane. The employee died from his injuries.
  • A worker was setting traffic cones for a paving project. A steel wheel roller was compressing the asphalt, and the traffic cones were being moved so that they would not be in the path of the roller. The worker was injured when he was struck by an automobile. He was thrown over the hood of the car and into another lane of traffic, where he was struck by another automobile. He was dragged 141 ft by the second vehicle. He was pronounced dead at the hospital.
