Maintenance worker dies after pinned between overhead bridge crane and roof truss.
NIOSH 2006 Sep; :1-7
On August 2, 2005, a 55-year-old maintenance worker (the victim) was pinned between an overhead bridge crane and a roof truss. The victim was part of a two-man maintenance team that ascended 20 feet up a ladder and climbed onto a 30-ton Whitney bridge crane. The victim and another maintenance man were going to adjust the brakes on the 5-ton hoist on the crane. While the operator of the Whitney crane had his back turned from the controls, a second operator came over and moved the crane. He did not know that the victim and another maintenance man were working on the crane above. The first operator realized what was happening and yelled to stop the movement, but it was too late. Management notified the Emergency Medical Services (EMS) at 8:28 a.m. EMS arrived at 8:31 a.m. The conditions the rescue personnel worked in included extreme heat, poor illumination, noise, and the accident site that was located over 25 feet above them. The FACE investigator concluded that to help prevent similar occurrences, employers should: 1. ensure that employees follow proper lockout tagout procedures on machinery before performing any repair, maintenance, or adjustments; 2. ensure that the employer conducts annual or more frequent inspections of the energy control procedures; 3. ensure that all controls are placed at the off position when adjustments and repairs are started on cranes; 4. ensure that warnings or "out of order" signs are placed on the cranes as well as on the floor beneath or on the hood where they are visible from the floor.
