Do you know what PPE is? PPE stands for Personal Protective Equipment, and it could save your life and limb. For power tools, there are specific PPE made to protect your hearing, your eyes and your skin from being damaged in one way or another. It is important that you pick the right type of PPE for the job and the tools you are using.
Your PPE should be worn the whole time while you are using the power tool. If you feel like it is getting uncomfortable, try stopping to readjust the PPE so that it gets more comfortable, or take a break for while. Many accidents happen because the PPE was removed due to discomfort. Same thing goes for trying to do something that requires fine motor control, when you feel like the PPE is getting in your way.
The quality of your PPE will usually make a difference both in the comfort when using it as well as how well they will protect you.
