10 Ways to make you stay safe with saws
If not used properly, chainsaws can cause horrendous injuries and even death. Here we examine the many modern features that make them as safe as possible
According to Tree Care Ireland's Kevin Birchall, there are 10 safety features on a modern chainsaw, many designed to reduce or eliminate the risk of injury.
1 Chain brake and front hand guard: If the chain does move when the brake is on, then the brake is defective. There is an inertia trip mechanism integrated into the brake as well so, if you get a bad kick-back, it triggers the brake to stop the chain, reducing the risk of serious facial or body injuries if the saw strikes.
2Rear hand guard: This is not just for standing on while you start the saw. It also prevents the chain from hitting your hand and fingers if it comes off the bar and whips back. Kevin pointed out that it also prevents branches hitting your hand during work.
3Chain catcher: This prevents a broken chain from flying off and hitting the operator or co-worker. It works like a Bolas with the momentum of the escaping or derailed chain causing it to wrap on the chain catcher lug.
4Safety throttle: This is a two-piece throttle mechanism. You have to compress the top piece with a proper grip on the handle to allow the user to operate the finger throttle.
5On/off switch: This is also a safety device -- the alternative of using the choke to stop it is not a safe way to stop a saw.
6The exhaust: You might not be thinking safety when looking at this but it is also a safety device because it directs the fumes away from the operator.
7Safety stickers: If these are damaged or missing, the saw is deemed unsafe in the eyes of the law.
