Close Call: Overhead console breaks free, strikes Loader Operator

Safety Alert Type: 
Heavy Equipment
Location: 
Vancouver Island
Date of Incident / Close Call: 
2011-12-21
Company Name: 
Western Forest Products
Details of Incident / Close Call: 

The two overhead console rear retaining bolts backed off causing the console to fall from its mounting location.

The console swung like a pendulum as it pivoted on the front hinges as it came down.

The radio microphone location and the back of the seat prevented the operators head from taking the full brunt of the console as it fell, causing only minor injuries (see images in the attached pdf).

Learnings and Suggestions: 
  • Ensure fasteners attaching overhead objects are of the correct minimum length, quality etc. and properly installed (such as using lock washers and Loctite). In this case, longer than factory bolts were installed after the incident in order to allow the threads to back out much further prior to coming completely out and allowing the console to fall.
  • The use of a secondary restraining device is strongly recommended on overhead objects to act as a backup if the primary fasteners fail. Ensure any modification done to equipment with FOPS or ROPS structures is done in a manner that does not jeopardize its structural integrity.
  • A scheduled inspection to ensure overhead objects are secured is recommended
