Each year in Ontario, construction workers are injured while using chainsaws. Generally the injuries result from two types of accidents:
Many of these injuries are serious or critical. While the chainsaw is relatively easy to operate, it can be lethal. As with all high-speed cutting tools, it demands the full attention of even the trained and experienced operator.
Workers must be adequately trained before using chain-saws. When using chain-saws workers must wear adequate personal protective equipment including protective clothing, gloves as well as eye and hearing protection. Chainsaws must be firmly held by both hands when cutting. Chainsaws used in construction must have “anti-kickback” chains also referred to as “safety chains”. They must also be equipped with a chain brake to prevent the chain from moving when the chainsaw is not in use.
Every gear, pulley, belt, chain, shaft, flywheel, saw and other mechanically-operated part of a machine to which a worker has access shall be guarded or fenced so that it will not endanger a worker.
