T48 0-16 Sentence denotes 8.1 Respiratory
T49 17-119 Sentence denotes N-95 respirators (see Fig 3 & Fig 3a & Fig. 4 15 ) are required for airborne protection from COVID-19.
T50 120-316 Sentence denotes Per OSHA regulations, HCW must be properly fit-tested with either a qualitative or quantitative device to ensure the mask makes a proper seal with the wearer's skin and offers adequate protection.
T51 317-385 Sentence denotes Users must be clean shaven for mask use as well as for the fit test.
T52 386-484 Sentence denotes Numerous brands are available from multiple manufacturers16 (see photos from NIOSH webiste below).
T53 485-579 Sentence denotes Users with beards cannot be fit tested with an N95, since an adequate seal is not possible17 .
T54 580-778 Sentence denotes HCW with beards can use a powered air-purifying respirator (PAPR) with a hood, since these function without the need for a tight skin seal and therefore also do not require fit testing (see photos).
T55 779-830 Sentence denotes Fig. 4 face shield and N95 for airborne protection.
T56 831-1018 Sentence denotes N95 designation is from NIOSH, meaning it is actually a dust-mist respirator which filters out 95% of small particles, but is not resistant to oil (N= Not; 95= 95% filtration efficiency).
T57 1019-1112 Sentence denotes An R95 has the same filtering capacity but is recommended for oily solvents (R= recommended).
T58 1113-1235 Sentence denotes Higher designations such as P100 mean they filter out 99.99% of particles (P= particles; 100=essentially 100% efficiency).
T59 1236-1445 Sentence denotes Higher levels of protection (i.e., R95, P100) are acceptable if a situation calls for N95 and an N95 is not available, but lower levels of protection (i.e., simple procedure or surgical mask) are not (Fig. 9).
T60 1446-1488 Sentence denotes Some of the styles of N95 masks available:
T61 1489-1543 Sentence denotes Photos courtesy of 3M, Kimberly-Clark, and Moldex 18 .
T62 1544-1676 Sentence denotes Since OSHA declares N95 masks for HCW as respirators, their use is governed by the OSHA Respiratory Protection Standard 1910.13419 .
T63 1677-1785 Sentence denotes Employers must have a program in place with the following components:• Written worksite specific procedures;
T64 1786-1807 Sentence denotes • Program evaluation;
T65 1808-1866 Sentence denotes • Selection of an appropriate respirator approved by NIOSH
T66 1867-1877 Sentence denotes • Training
T67 1878-1891 Sentence denotes • Fit testing
T68 1892-2006 Sentence denotes • Inspection, cleaning, maintenance, and storage (for loose-fitting hoods- N/A to disposable single-use N95 masks)
T69 2007-2028 Sentence denotes • Medical evaluations
T70 2029-2382 Sentence denotes Paragraph 1910.134(e)(2)(i) of the standard explains that the medical evaluations are to be performed by a physician or other licensed health care professional (PLHCP) identified by the employer to perform medical evaluations using a medical questionnaire or an initial medical examination that obtains the same information as the medical questionnaire.
T71 2383-2681 Sentence denotes The employer shall ensure that a follow-up medical examination is provided for an employee who gives a positive response to any question among questions 1 through 8 in Section 2, Part A of Appendix C 20 or whose initial medical examination demonstrates the need for a follow-up medical examination.
T72 2682-2806 Sentence denotes Questions 10-15 and all of part B regarding full-face respirators do not apply to HCW using N95 or loose fitting PAPR hoods.
T73 2807-3085 Sentence denotes Since the N95 respirator is a negative pressure respirator, if the PLHCP finds a medical condition that may place the employee's health at increased risk if the respirator is used, the employer shall provide a PAPR (such as the hood described above and pictured in Fig. 5, Figs.
T74 3086-3099 Sentence denotes 5 and 6 21 ).
T75 3100-3108 Sentence denotes Fig. 5 .
T76 3109-3114 Sentence denotes Figs.
T77 3115-3215 Sentence denotes 5 and 6 PAPR loose fitting hood with HEPA filters (no fit test required; suitable for bearded HCWs).
T78 3216-3479 Sentence denotes Fit testing for the N95 respirators is required, but can be performed qualitatively using isoamyl acetate (banana oi), saccharin solution, or Bitrex© Fig. 4a (see Fig. 4a), or quantitative using an approved device, such as Port-a-Count® (see Fig. 7, Fig. 8 ) 22 .
T79 3480-3597 Sentence denotes The fit test must be performed with exact make, model, and size of respirator the HCW with be using in the workplace.
T80 3598-3796 Sentence denotes Qualitative testing does not compromise the mask integrity and therefore after the test the employee can take the N95 with them for future single use (important consideration in time sof shortages).
T81 3797-3966 Sentence denotes Quantitative fit tests require insertion of a probe through the mask, compromising mask integrity, and therefore the N95 must be discarded after a quantitative fit test.
T82 3967-4254 Sentence denotes Fit testing is not required for loose-fitting PAPR hoods (which are used primarily by HCW with facial hair that does not allow a proper seal), because the breathing zone environment is under positive pressure and therefore a tight seal is not required for proper function and protection.
T83 4255-4300 Sentence denotes Fig. 7 Fit testing N95 mask with PortaCount®.
T84 4301-4349 Sentence denotes Fig. 8 Portacount® quantitative fit test device.
T85 4350-4420 Sentence denotes Fig. 9 Simple procedure mask with integrated face shield (not an N95).
T86 4421-4444 Sentence denotes Used by general public.
T87 4445-4497 Sentence denotes This could be worn on top of N95 for eye protection.
