Harvester (chain, bars, sprockets and accessories):   What is
chain shot? 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 mechanized 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.
Industry research indicates an average of 1 in 50 broken chains
had parts missing that may have been the result of a chain shot
event.  How can operators reduce the risk of chain shot?    •
Operators and bystanders must never be in the plane of the bar
when the chain is in motion on the bar.   • Appropriate
windshield material must be installed.   • Chain speed must be
40 m/s (8000 ft/min) or less for .404 pitch Oregon® Harvester
