9. Respiratory Terminology

10. Respiratory Terminology • Tight fitting facepiece – a respirator inlet covering that forms a complete seal with the face • Positive pressure respirator- a respirator in which the pressure inside the respiratory inlet covering exceeds the ambient air pressure outside the respirator. • Negative pressure respirator – a respirator in which the pressure inside the facepiece is negative during inhalation with respect to the ambient air pressure outside the respirator.

11. Respiratory Terminology • Atmosphere-supplying respirator –a respirator that supplies the user with breathing air, such as: SCBA, Rebreather or SAR • Pressure demand respirator – a positive pressure ASR that admits breathing air to the facepiece when the positive pressure is reduced inside the facepiece by inhalation. • Air-purifying respirator – a respirator with an air-purifying filter, cartridge, or canister that removes air contaminants by passing ambient air through the element. • Powered air-purifying – an air-purifying respirator that uses a blower to force the ambient air through the element to the inlet covering.

12. Respiratory Terminology • Fit test – the use of a protocol to quantitatively or qualitatively evaluate the fit of a respirator on an individual. • Qualitative fit test (QLFT) – a pass/fail test to assess the adequacy of respirator fit that relies on the individual’s response to the test agent. • Quantitative fit test (QNFT) – an assessment of the adequacy of respirator fit by numerically measuring the amount of leakage into the respirator.

13. Check on Learning A facepiece that forms a complete seal with the users face is referred to as what type of facepiece? Tight fitting facepiece.

14. Respiratory Protection Program

15. Respiratory Protection Program Sub paragraph C of 29 CFR 1910.134 requires the employer to develop and implement a written respiratory protection program with required worksite-specific procedures and elements for required respirator use. * In any workplace where respirators are necessary * Administered by a suitable trained program administrator * Voluntary use

16. Respiratory-Use Requirements Flow Chart 29 CFR 1910.134 (c) Are respirators: * necessary to protect the health of the employee; or * required by the employer ? Yes No Does the employer permit Voluntary use of respirators ? Must establish & implement a written respirator program with worksite-specific procedures Yes No STOP Does the only use of respirators involve the voluntary use of filtering facepieces ? Yes No * Employer determines respirator doesn’t create a hazard * Provide info in Appendix D * No respirator program required * Employer determines respirator doesn’t create a hazard * Provide info in Appendix D * Must establish & implement those elements of a written respirator program necessary to ensure that employee is medically able to use that respirator

17. Written Respiratory Protection Program • (c)(1)(i) Procedures for selecting respirators in use in workplace * Evaluate Hazards * NIOSH Certified Respirator • (c)(1)(ii) Medical evaluations of employees required to use respirators • (c)(1)(iii) Fit test procedures for tight fitting respirators

18. Written Respiratory Protection Program • (c)(1)(iv) Procedures for proper use of respirators in routine and reasonably foreseeable emergency situations • (c)(1)(v) Procedures and schedules for cleaning, disinfecting, storing, inspecting, repairing, discarding and otherwise maintaining respirators • (c)(1)(vi) Procedures to ensure adequate air quality, quantity, and flow of breathing air for ASR

19. Written Respiratory Protection Program • (c)(1)(vii) Training of employees in the respiratory hazards to which they are potentially exposed during routine and emergency situations • (c)(1)(viii) Training of employees in the proper use of respirators, including putting on and removing them, any limitations on their use and their maintenance • (c)(1)(ix) Procedures for regularly evaluating the effectiveness of the program

20. Check on Learning What are the nine components of a Written Respiratory Protection Program? (c)(1)(i) thru (c)(1)(ix)

21. Respirator Fit Testing

22. Qualitative(QLFT) • Isoamyl Acetate Protocol • * Requires an odor threshold screening • Saccharin Solution Aerosol Protocol • * Requires a taste threshold screening • Bitrex Solution Aerosol Protocol • * Requires a taste threshold screening • Irritant Smoke Protocol • * Requires a sensitivity screening check

23. Qualitative(QLFT) Isoamyl Acetate (banana oil) Bitrex Sodium Saccaharin Irritant Smoke

24. Qualitative(QLFT) Advantages Disadvantages * Inexpensive up-front cost * Imprecise * Low maintenance * Easy to do wrong (tedious) * Limited to fit factor of 100 * Subject to deception * No documentation of results * People dislike wearing the hood * Slow (because of threshold test)

25. Quantitative(QNFT) • Generated Aerosol Quantitative Fit Testing • Protocol • Using a non-hazardous aerosol such as: • * corn oil • * polyethylene glycol • * sodium chloride • * di-2-ethyl hexyl sebacate • Overall Fit factor= number of exercises…. • 1/ff1+1/ff2+1/ff3+………1/ff8

26. Quantitative(QNFT)

27. Quantitative(QNFT)

28. Quantitative(QNFT) Advantages Disadvantages * No fit factor limit * More expensive up front cost * Precise * Requires probed respirator or * Faster a Sampling adapter * Annual factory recalibration * No chance of deception * recommended * Easy to do right * Useful for employee respirator training * Hard copy documentation of results

29. Fit Test Record • The employer shall establish a record of the qualitative and quantitative fit test administered to an employee. • The record shall include: * employee name or ID * type of fit test * specific make, model, style of respirator * date of test * pass/fail for QLFT * fit factor for QNFT

30. Fit Test Record • The fit test record will be maintained until the • next administered test: • * Annual test • * Changes in respiratory protection • * Changes in the employee

31. Check on Learning Which type of Fit Test requires a threshold screening? Qualitative(QLFT)

32. Medical Evaluation

33. Medical Evaluation • The employer shall provide a medical evaluation to determine the employee’s ability to use a respirator. • Prior to fit testing and use • May be discontinued when employee is no longer required to use a respirator

34. Medical Evaluation Procedures • The employer shall identify a physician or other licensed health care professional (PLHCP) • The medical evaluation shall obtain the information requested by the questionnaire in section 1 and 2, part A of appendix C. • The employer shall ensure that a follow up medical evaluation is provided for an employee that give a positive response to questions 1- 8, or gives indication that a follow up is needed.

35. Medical Evaluation Procedures The medical questionnaire and examination * administered confidentially * during the employee’s normal working hours * or at a time and place convenient to the employee.

36. Check on Learning Who is authorized to administer medical screening? The employer shall identify a physician or other licensed health care professional (PLHCP)
