Health Tip: Using a Chainsaw
|
(HealthDayNews) -- While a chainsaw can be a handy tool, it can also be dangerous. You should get formal instruction in the safe operation of a chainsaw before you use one for the first time, says a University of California, Berkeley article on chainsaw safety. Most chainsaw injuries involved deep gashes to the hands, legs, feet and head. Kickback -- which occurs when the upper part of the chain bar tip meets resistance -- is the most common cause of serious injury. New chainsaws do have safety features such as chain breaks, but kickback is still a threat. Proper training and instruction, including how to avoid potential kickback situations, is the best way to prevent injury. You must wear full safety gear when using a chainsaw. This includes a hardhat, eye and ear protection, gloves and leg chaps. Keep your chainsaw sharp. It will require less effort to use and reduce fatigue. Don't use a chainsaw when you're tired, which could increase your risk of injury.
