Details of Incident / Close Call: 

A Caterpillar tractor was towing a loaded log truck through a muddy section of the landing to the main haul road. During the tow, the chain snapped, whipping back at the truck with force.

The windshield was broken. No injury to driver. All workers were in the clear.

Learnings and Suggestions: 
  • Safe work procedures must be developed and followed for towing trucks
  • Complete a risk assessment which considers communication plan, workers being in the clear, length of pull, choice of equipment used to pull, connections, inspection of line and rigging, and road obstacles (eg, rock, out-sloped roads, corners)
  • Tow chain or cable must be inspected and deemed adequate strength for the estimated breaking force and weight presented in the tow operation
  • Consider postponing hauling until road conditions have improved.
