18. Filter Selection • Levels of filter efficiency are 95%, 99%, and 99.97% • Number is dependent on how much filter leakage can be accepted • Categories of resistance to filter efficiency degradation are labeled N, P and R • N ~ Not resistant to Oil • R ~ Resistant to OIL • P ~ Oil-Proof • If no oil particles are present, use any of the above • If oil particles are present, use only R or P • If oil particles are present and the filter is to be used for more than one work shift, use only P series

19. Medical Evaluation • Must be provided to determine the employee’s ability to use a respirator • Must be completed before fit testing and use • A PLHCP must be identified to perform medical evaluations through: • A medical questionnaire • Initial medical examination • The medical evaluation must obtain information requested in Appendix C Part A Sections 1 and 2 • Follow-up medical examination is required when: • Employee answers “Yes” to Question 1 - 8 in Section 2, Part A of Appendix C • Initial medical examination demonstrates need for follow-up

20. Additional Medical Evaluations • Annual review of medical status is not required • Medical evaluations must be provided at a minimum if: • Employee reports medical signs or symptoms related to the ability to use a respirator • PLHCP, supervisor or Program Administrator informs employer of employee reevaluation • Information from respirator program indicates a need for reevaluation • Program evaluation • Observations made during fit testing • Changes in workplace conditions may increase physiological burden

21. Fit Testing • Employee must be fit tested with same, make, model, and size of respirator that will be used before any use commences with a positive or negative pressure tight fitting facepiece • Employees must pass a Qualitative Fit Test (QLFT) or a Quantitative Fit Test (QNFT) • Prior to initial use • Whenever different respirator is used • At least annually thereafter • Additional fit test must be conducted when the employee’s physical condition changes that could affect fit of respirator • Facial scarring • Dental Changes • Cosmetic Surgery • Change in Body Weight

22. Qualitative Fit Testing • A pass/fail fit test to assess the adequacy of the respirator fit.
