  1. UNC - CHHealth & Safety Office Respiratory Protection for Tuberculosis

  2. Why the Respiratoris Necessary? Healthcare facilities present an environment where there is a risk for transmission of Tuberculosis through airborne infectious particulates. Respirators, such as the N-95, provide protection from airborne infectious particulates when properly fitted and worn. Click For more information concerning Tuberculosis and Infection Control

  3. OSHA (1910.134)Respiratory Standard OSHA’s Respiratory Protection Standard requires that the employer have a written program that includes annual: - Medical screening to determine if the employee is physically able to wear a respirator. - Fit-test to determine if the respirator fits properly on the employee’s face. - Training on the selection, use, storage, and limitations of the respirator used.

  4. When should you wear a respirator? A respirator is to be worn: - when entering TB isolation rooms, - when patient is suspected of having TB, - during procedures that generate airborne secretions such as sputum induction

  5. Selection ofRespirator The most common respirator used is the disposable particulate type N95. The “N” stands for respirator filters that can be used when no oil is present in the contaminants. The “95” means that the product has been tested and certified by NIOSH to have a filter efficiency level of 95% or greater against particulate aerosols.

  6. Donning of N95 Respirator Step 1 Cup the respirator in your hand with the nosepiece at finger tips allowing the headbands to hang freely below hands.

  7. Donning of N95 Respirator Step 2 Position the respirator under your chin with the nosepiece up.

  8. Donning of N95 Respirator Step 3 Pull the top strap over your head so it rests high on the back of head.

  9. Donning of N95 Respirator Step 4 Pull the bottom strap over your head and position it around neck below ears.

  10. Donning of N95 Respirator Step 5 Using two hands, mold the nosepiece to the shape of your nose by pushing inward while moving fingertips down both sides of the nosepiece. Pinching the nosepiece using one hand may result in less effective respirator performance.

  11. Fit Check of N95 Respirator Face Fit Check - The respirator seal should be checked before each use. To check fit, place both hands completely over the respirator and exhale. If air leaks around your nose, adjust the nosepiece as described in step 5. If air leaks at respirator edges, adjust the straps back along the sides of your head. Recheck.

  12. RespiratorEffectiveness Respirators are only effective when the seal around your nose and mouth is tight. If you cannot achieve proper fit, do not enter the isolation or treatment area. Consult your supervisor. A respirator cannot be worn by healthcare workers with facial hair that comes between the sealing surface of the mask and face. Bearded healthcare workers should contact the Health and Safety Office to obtain information on alternative respiratory protection.

  13. Removal of N95 Respirator Step 1 Cup the respirator in you hand to maintain position on face. Pull bottom strap over head.

  14. Removal of N95 Respirator Step 2 Still holding respirator in position, pull top strap over head.

  15. Removal of N95 Respirator Step 3 Remove respirator from face and discard.

  16. What are the limitations of the N-95 respirator? The N-95 respirator has the ability to filter particles 1 micrometer with a filter efficiency of > 95%. If this respirator becomes wet, it is no longer effective and must be replaced. The N-95 is not intended for protection from organic vapors, toxic gases, or toxic particulates. Consult your supervisor or the Health and Safety Office if you have questions regarding respiratory protection.

  17. Conclusion If you have any questions regarding respiratory protection, consult your supervisor or the Health and Safety Office at 962-5507. Proceed to the post test
