Wearer must always do a fit check whenever he/she wear a respirator. 3. If wearer is not getting a proper fit then he/she must report this to the supervisor. 4. After wearing a respirator if you smell something or taste something then it simply mean that your respirator is giving you a perfect fit. 5.

(On half face or full face respirators you must put your hands over the place where you attach the filters to your respirator) 2. Now start inhaling slowly for count of fifteen. You should not push on the mask but should simply inhale after placing your hands over air inlet 3. Now check if the respirator facepiece pulls towards your face. At this point no air should come inside the facepiece. No air should leak inside. 4. Cover the area where air leaves the mask. 2/4

Now same as step 3 you must check for leaks between your face and the facepiece of the respirator. 7. If you do not detect any leaks then it means you have got the desired tight seal which will prevent any leakage to the mask. But if you detect any leaks then you must readjust your facepiece. Try adjusting your straps and then again check for a proper fit.

How to Properly Fit Check and Fit Test Your Respirator Qualitative fit testing One must always check the instruction guide that comes with the respirator to get a desired tight seal. With a beard or facial deformities, the person may be unable to pass a fit test. These workers can use a powered air-purifying respirator. Air purifying respirator should not be used where oxygen supply is less than 20% in the environment. In an oxygen deficient zone worker must wear a supplied air respirator. People suffering from heart disease, lung problem, asthma or form any breathing problem must avoid wearing air purifying respirator because breathing through respirator is hard. 1. Always choose the respirator for yourself that fits best on your face. A best fitting respirator will provide a great seal to your face. 2. Always perform a fit when you buy a new respirator. Also if you undergo any facial change such as scarring, dental change, cosmetic surgery or obvious weight change, then also you must perform a fit check. 3. You can choose the respirator according to your face size and it comes in different sizes and models. 4. Always wear a respirator that gives you appropriate seal and then perform a fit check. 5. The first step towards checking the fit test is by detecting the fit testing agent by smelling or tasting it without wearing a respirator. If you smell or taste the testing agent after wearing the respirator then it means you need to check the seal as there may be the chances of leakage in it. 6. Whenever you taste the testing agent on any respirator including disposable “dust/mist� respirator while wearing it, it simply means you do not have a proper seal.
