Fit testing is essential for a respirator to provide protection. Facepieces for all respirators are normally available in a range of sizes to fit the majority of workers. However, it is sometimes difficult to get a tight fit with workers for a wide variety of reasons. We can work with you to ensure that the seal is not compromised by many common and some not-so-common factors including jaw movements and eyewear while still being sensitive to the wearers comfort level. We will save you time, embarassment, and possibly your life!
