SAFETY HAZARD ALERT
ALERT: Chain Shot
Injuries and fatalities have been occurring in the forest industry due to processor ‘Chain shot’. Chain shot is when a processor chain breaks and the broken link is whipped or shot (sometimes in excess of 8,000 ft /second) from the processor head. This link travels at such a high rate of speed that it can severally injure or kill a worker if struck. Recently, K&D Logging experienced a ‘chain shot’ which pierced through a 12mm Lexan window and lodged in an operator’s leg, just below the knee. The operator required surgery to remove the 2 links from his leg.
Ground crews should never work within a 300ft radius of an operating processor. If an individual is checking log quality (other than the operator), please shut the processor off and join the individual with the quality check. Do not run the machine while anyone is within the 300ft limit.
- Never operate the main saw in front of the cab. Always tilt the head so the bar is angled away from the cab. Positioning the head a few degrees can mean all of the difference in avoiding a direct chain shot.
- Discuss with your supervisor if you are processing safely to avoid chain shot. Have someone else watch the way you process to ensure that you are being safe and that you are positioned correctly.
- There will be more information and training from the supervisors on how to recognize excessive chain wear. Currently, K&D Logging has a chain re-sharpening program. The current program disposes of chains when: there is a broken link, damage to 2 or more teeth, excessive wear or more than 3 sharpenings. There will be more information on this topic as we learn from our chain supplier (Stihl) and from others who manage a chain sharpening program.
- WorkSafe BC is working with manufacturers and dealers to develop engineered controls (barriers or guarding) to limit the risk of chain shot. Until these controls are finalized, operators need to ensure proper head positioning while cutting and avoid using chains with excessive wear.
- Supervisors and Lead charge hands are there to help, so please if you have any questions or concerns – speak up and ask.
