There are no safety measures required to operate a weed eater. However, there are some recommendations that are wise to adhere to during use. Safety goggles, as well as safety gloves and boots, are encouraged to be worn during operation to protect the user from any debris. It is also important to take a look at the string guard. The larger the string guard, the more protection you have against debris thrown from the weed eater. It is also recommended to wear hearing protection when operating louder models, such as a gas-powered weed eater.
