Sep 20, 2009
The optimal use of N95 respirators is aided by proper training on how to fit test, wear, store and discard these protective masks. The desired protection against the H1N1 virus will be possible only if the N95 respirators are tested and worn according to the instructions.
What are the Precautions to be Taken Before Wearing N95 Respirators/Masks?
Before wearing a N95 respirator, one should
- Make sure that one does not have any medical or physical condition which limits or prohibits its use.
- Make sure that the N95 is from a NIOSH (National Institute for Occupational Safety and Health) certified manufacturer.
- See that the N95 respirator is fit tested so that its intended purpose is not compromised.
- Get proper training on the use, storage and disposal of the N95 respirator.
What is the Proper Technique of Wearing the N95 Respirators?
- Check the respirator for any manufacturing defects, tears etc. If it is damaged in any way, do not use it.
- Check the headbands for proper elasticity
- Holding the upper and lower headbands with your index fingers and thumbs, cup the respirator firmly over the chin and backwards.
- Bend the nose clip firmly over the bridge of nose to get a tight fit in that area
- Put the lower headband over your head and secure it tight at the base of the neck behind, below the ears.
- Secure the upper headband tightly behind the head, over the ears.
- Once again press over the nose clip to make it tight over the nose.
- Adjust the headbands and nose clip and do a fit check for the N95 respirator.
How to Know Whether the N95 Respirators is Fitting Properly?
Before using a N95 respirator for the first time and each time thereafter, a fit check should be carried out to ascertain that the N95 respirator is airtight and effective.
How to Perform a Fit Check for the N95 Respirators?
Following is a simple way to fit check yourN95 respirator
- Wear the N95 mask as per directions
- Cup the N95 respirator softly with your palm
- Take a forceful, deep breath. You will feel the respirator collapse.
- Now breath out a forcefully, the respirator will expand
- Repeat this half a dozen times. If the above observation is sustained, the N95 respirator has passed the fit check.
- If it does not and you feel the air leaking out, adjust or tighten the mask strings and repeat the fit check.
How to Properly Remove the N95 Respirators?
While removing the respirator, take care not to touch the front of the respirator. This may be contaminated and contain the H1N1 virus and other pathogenic germs and dirt.
Remove the respirator by pulling the strings over the head and lifting up the respirator from the bottom end.
When to Discard the N95 Respirators?
- If you are a healthcare provider, discard the mask after a single use of 6-8 hours.
- If you are using the mask whenever you go to crowded places (though not recommended); and if economically nonviable to use a fresh mask each time, you may store the mask/respirator outer side upwards in a clean place away from direct sunlight and reuse it twice or thrice, not more.
- You should discard the N95 respirator if it becomes soiled, when the breathing through the respirator becomes difficult, or when the inhaled air is smelly or moist.
N95 respirators are only useful when worn correctly after fit testing. Without fit testing, there is no evidence that these respirators provide more protection than the common surgical face mask.
