Chain shot - Speed of a Bullet

FISA Safety Bulletin - updated May 2020

FISA's Plant & Equipment Working Group has issued an update to this Chain shot Bulletin with a cone zone image added.

Chain shot is the high velocity separation and ejection of a piece or pieces of cutting chain from the end of a broken chain in mechanised timber harvesting. Chain shot exposes both machine operators and bystanders to a risk of serious injury or death. Chain shot typically occurs near the drive end of the cutting system but can also come from the bar tip area.
