Low bed booster axle moves too far, worker suffers fractured leg

Safety Alert Type: 
Vehicles
Location: 
Northern Interior Region
Date of Incident / Close Call: 
2017-11-11
Company Name: 
CANFOR
Details of Incident / Close Call: 

A low bed operator attempted to disconnect the booster axle from the beavertail of a low bed trailer before disconnecting the air supply first.

The ground was frozen and icy so the booster axle slipped off and slid a greater distance than normally is the case before coming to a complete stop. The operator's leg was fractured when it got “pinched” in between the booster axle and trailer.

Potential Hazards

  • Complacency, as typically the booster axle will only slide a short distance before coming to a stop when it comes in contact with the road
  • Not following the proper safe work procedures
  • Completing work on icy ground that was not flat
  • Standing in the “line of fire” or “bight”.

 

Learnings and Suggestions: 

Review safe work procedures with all operators:

  • Only attempt to disconnect the booster axle on level ground
  • Disconnect the air supply to the booster axle and ensure brakes have engaged before proceeding
  • Caulk wheels on booster axle to ensure it cannot slide or roll away
  • Disconnect the booster from the trailer
  • When all clear, slowly pull the tractor trailer ahead allowing the booster axle to slide off
  • Never stand in the “line of fire” and stay clear of the “bight”.
