Soft shoulders on newly-constructed road lead to log truck rollover

Safety Alert Type: 
Resource Roads
Location: 
Greenwood, BC (Jewel Lake area)
Date of Incident / Close Call: 
2015-07-30
Company Name: 
Interfor - Grand Forks Division
Details of Incident / Close Call: 

A logging truck steered around a slight bedrock protrusion which caused the trailer to lean outward and track into the soft shoulder. The trailer rolled over the bank and pulled the truck onto its side.

Hazard: Recently constructed road with soft, powdery shoulders concealed a dip in the road’s subgrade.

Learnings and Suggestions: 

Actions to Prevent a Re-Occurrence:

  • Report potentially unsafe road conditions to your site supervisor.
  • Consider the use of a water truck and compacter when constructing roads in dry conditions, particularly when subgrade consists of fine textured soils.
  • Roads must be “set-up” and ready for hauling. If a road is too soft, narrow, has poor alignment or out-slopes, fix it before hauling starts.
  • Always stay alert while driving; even a slight distraction can have major repercussions.
  • Drivers must be cautious when hauling a new load configuration as this can alter the center of gravity and reduce truck stability.
