Details of Incident / Close Call: 

An employee was using an All-Terrain Vehicle (ATV) to return to the truck at the end of the day. The road being travelled down was heavily overgrown with alder and the ride was slow.

In one particularly thick area the quad had to work hard to push against the growth of the alder. At this point a piece of alder broke off and became lodged in the throttle mechanism. The machine began to pick up speed in the thick alder and the operator had a difficult time maintaining control of the machine as the throttle was stuck on.

Because the alder was thick it was difficult to gear down and in order to gain control of the machine the operator had to turn the key off to remove the power source to the ATV. Once the machine was stopped the operator was able to remove the piece of alder from the throttle and the machine was restarted and the throttle tested to make sure it would decelerate. The rest of the trip was event free.

Learnings and Suggestions: 

• ATV safe work procedure was amended to include information on what to do if the throttle gets stuck – attempt to gear down and brake. If all else fails, turn off the ignition source.
