The wearing of personal safety equipment isn't a matter of choice, but rather a matter of life or death. Wearing the correct respirator when using specific actives is a must. Not all respirators are the same and the one used for sanding may not be the right one for working with solvents. Most suppliers can provide you with a helpful chart to find the right one for you. Also, getting a good fit is just as important as using the right one. Respirators come with directions on how to get the right fit and a test. Now that you have the right respirator and it fits well be sure and change the filters and take good care of it and it will take care of you.
