Struck-By Falling Objects

You are at risk from falling objects when you are directly beneath cranes, scaffolds, or overhead work being performed, etc.

When working around cranes, don't forget to look up!

Injuries can range from minor abrasions to concussions, blindness, or death.

Examples

  • A worker was tearing down a transmission structure using a digger-derrick when a pole broke and struck him on the head.
  • A worker was struck by a load of wall panels that fell off his truck.
  • Four workers rebuilding a bridge that had washed out by floods were injured when a crane boom cable broke, and the boom fell on them.
  • A worker was engaged in cutting an 8,000-lb boiler in sections with a cutting torch. The section being cut fell off allowing the remaining 5000-lb section, to flip over onto its bottom and land on the worker.
  • A worker was assisting a rigger who had attached a load to the block hook of a wheel mounted crane. The crane operator was positioned in the cab and waiting for the hand signal to make the lift. During this process, the jib of the crane fell from its stowed position on the boom and struck the worker. The worker died later at the scene. It was discovered that the pin used to secure the jib to the boom was missing thus allowing the jib to be displaced. The crane was not inspected prior to use.
