Close Call: Log truck suspension airbag explodes while in the shop

Safety Alert Type: 
Heavy Equipment
Mid Island Forest Operations (Campbell River, BC area)
Date of Incident / Close Call: 
Company Name: 
Western Forest Products Inc.
Details of Incident / Close Call: 

While removing a rock from between duals, the adjacent air bag exploded.

The worker was wearing PPE including safety glasses; no injuries resulted.

Learnings and Suggestions: 
  • Airbags can be deflated at any time with an air control valve in the dash; this should only be done when the truck is stationary.
  • Deflation and re-inflation can take place if truck is loaded. Air bags have approximately 30PSI of air pressure when the truck is empty, and can have 80 – 100PSI when the truck is loaded. Local truck dealership representative confirms there is no reason why the air bags can’t be inflated with a load on.
  • Always deflate the air bags if working in close proximity (changing tires, servicing, welding, etc.) and protect if welding/cutting is taking place to prevent damage.
