Respiratory Protection Program

1. Respiratory Protection Program

2. Safety through teamwork “Nothing is so important that it can not be done safely.”

3. Training Outline • Introduction • Respiratory Hazards • Medical Evaluations • Respirator Selection • Proper Wear of Respirators • Fit Testing • Respirator Maintenance • Use and Limitations of Respirators • QUIZ

4. OSHA Respiratory Protection Standard • Standard 29 CFR 1910.134 • Assess the workplace and provide respirators when necessary to protect the health of employees • Develop and implement a written respiratory protection program • Provide training on how to properly use respirators • Provide medical evaluations at no cost to the employee

5. The Lungs • Inhalation is the most direct route to the bloodstream • Inhalation of hazardous materials damages the delicate structures of the lungs • Damaged lungs are more susceptible to respiratory disease

6. Respiratory Hazards • Respiratory protection is required when employees are in areas where effective engineering controls are not feasible to protect the health of the employee from : • lack of oxygen • harmful dusts, fogs, fumes, mists, gases, smokes, sprays or vapors • Respiratory Protection must comply with NIOSH/MSHA

7. Respiratory Protection • Exposure levels exceed PEL • During installation of engineering or work practice controls • Maintenance and repair activities that may result in exceeding the PEL • Emergency Response where type and/or concentration of contaminant is unknown • Voluntary Usage

8. Voluntary Use of Respirators • ECU may provide respirators at the request of the employees or permit employees to use their own respirators • The University must ensure that any employee using a respirator voluntarily is medically able to use that respirator

9. Voluntary Use of Respirators Employee precautions: • Read instructions on use, maintenance, cleaning and care, and warnings • Use NIOSH certified respirators only • Wear respirators designed for your specific use • Keep track of respirator so you do not mistakenly use someone else’s

10. Medical Surveillance • Medical evaluations must be provided to determine each employee’s fitness to wear a respirator • These evaluations are required for all respirator users except for employees who voluntarily use dust masks and for the use of escape-only respirators • Medical evaluation records will be retained for 30 years beyond the employee’s employment

11. Respirator SelectionThe selection of respirators depends on what the hazard is and its extent, choosing approved equipment, and ensuring the device is certified.

12. Respirator Selection • Chemical & physical properties of the contaminant • Toxicity & concentration of hazardous material • Amount of oxygen present • Limitations & characteristics of available respirators

13. TYPES OF RESPIRATORS Air- Supplied- Combination Purifying Air

14. Proper Wear Employers shall not permit the use of respirators for employees that: • Have facial hair that interferes with the seal or valve function of the respirator • If PPE is used such as corrective glasses, the employer will ensure that the PPE will not interfere with the seal of the respirator

15. Criteria for Determining Comfort • mask position on nose • room for eye protection • room to talk • mask position on face and cheeks

16. Criteria for Determining Adequacy of Fit • Chin properly placed • Adequate strap tension, not too tight • Fit across nose bridge • Respirator of proper size to span distance from nose to chin • Tendency of respirator to slip • Self-observation in mirror to evaluate fit and respirator position

17. Fit Testing • Fit testing is required for all employees using negative or positive pressure tight-fitting respirators • Must be repeated annually and whenever a different respirator is used • Qualitative Fit-Testing is used for this program

18. Fit Testing • Employee shall be allowed to pick the most acceptable respirator from all the models and sizes that will provide most adequate protection • Fit test shall be performed wearing any applicable safety equipment that may be worn during actual respirator use • No respirator will provide adequate protection without a tight seal between the facepiece and the face of the wearer

19. Fit Testing • Employer shall demonstrate: • how to put on a respirator • how it is positioned • how to set strap tension • how to determine an acceptable fit • Employee shall conduct: • Negative seal check • Positive seal check

20. Fit Test Exercises • Normal breathing • Deep breathing • Turning head side to side • Moving head up and down • Talking • Grimace (smile or frown) • Bending over

21. Taste Threshold Screening • EH&S will conduct a Taste Threshold Screening to help determine adequate fit of the respirator • If the test fails, a different respirator must be tried

22. Respirator Maintenance All respirators must be cleaned, stored and inspected regularly. This is necessary to provide complete protection.

23. Cleaning • Must be cleaned regularly • Respirator should be cleaned and disinfected if used by more than one person • Disassemble the respirator and soak in warm water and rinse with clean water • Respirators may be washed in a detergent solution and then disinfected in a sanitizing solution • Air dry all parts of the respirator or wipe dry with a clean lint-free cloth

24. Storage • Respirators must be stored to protect against dust, sunlight, temperature, moisture, and chemicals • Not to be stored in lockers or tool boxes • Stored so that facepiece and valves will rest in a normal position • Respirators should not be stored by hanging them by the headband

25. Inspection • Respirators should be inspected before and after each use to ensure all parts are present and operating • Rubber and elastomer parts should be checked for pliability and signs for deterioration • Any worn or deteriorated parts should be replaced-cracks, tears, holes , gaskets

26. Special Maintenance Features • Filters and cartridges must be changed periodically • All filters must be properly labeled and color coded • Self-contained breathing apparatus must be inspected monthly • Use of SCBA’s is restricted to employees of the Office of Environmental Health and Safety

28. Use and Limitations • The respirator is the last control measure to ensure safety to the employee • The respirator is necessary to prevent the inhalation of aerosols and contaminants • Employees must be familiar with the respirator and its operations • The respirator must have a proper seal and effective valves in order to perform its job

29. Use and Limitations Use and limitation information for the respirators utilized in this program include the following: • Employees must leave the area if the contaminant can be detected by dizziness • If the respirator is damaged or breathing becomes difficult, the employee must leave the area • Not all respirators supply oxygen to employees • The manufacturer’s operation manual should be used as a reference for additional use

30. Program Evaluation The Respiratory Protection Program will be evaluated annually by the Office of Environmental Health and Safety Factors that will be assessed include: • Respirator fit • Appropriate respirator selection for the hazards to which the employee is exposed • Proper respirator use under the workplace conditions the employee encounters • Proper respirator maintenance

31. Airline Respirator Advantages & Limitations • Advantages – • continuous air supply, • lightweight, • less maintenance, • don’t need to buy tank air Limitations- • tied to a 300 ft. hose, • depends on output of compressor, • need an attached escape bottle in IDLH conditions 20

32. SCBA Advantages & Limitations • Advantages • highest form of protection, • can be used anywhere, • allows unrestricted mobility • Limitations • heavy & bulky, • limited air supply(30 - 60 min.), • extensive training required, • high maintenance 21

33. Using SCBAs – Special Notes SCBAs are sophisticated respirator equipment used for possible or actual life-threatening situations. SCBAs should not be used without extensive hands-on training and frequent re-training. Most SCBA manufacturers or distributors provide this training. If you have large chemical spill or leak, it may be safer to call professional emergency responders. 22

34. Air Quality ForSCBAs Air for breathing must be “Grade D” air Grade D air for tanks is usually purchased from a specialized supplier. Grade D air must meet strict requirements. link to WISHA requirements Supplier must certify that tank air meets Grade D requirements. 23

35. Air Quality for Airline Respirators Air compressors must deliver clean air Locate pump intake in an area of clean, fresh air. Filter air as needed. Watch out for nearby running engines. Be sure air intakes are located away from exhaust pipe of an engine compressor. Small electricair pump Small engine compressor 24

36. Compressors for Airline Respirators Three types of breathing air compressors Gasoline high pressure air compressor Electric low pressure compressor Electric high-pressure air compressor 25

37. Construction & Plant Air Compressors Use these compressors with caution Be careful – these do not provide clean air without a filter system!! Oil-lubricated compressor are especially hazardous. Must test for carbon monoxide or have high temperature alarm. Engine exhaust can also contaminate breathing air. 26

38. Compressor Air Filters What air filters are needed on compressors? Moisture trap Dust filter Hydrocarbons(oil, solvents) absorbent Carbon monoxide alarm or high-temp. alarmfor oil-lubricated compressors compressor filters carbon monoxide alarm 27

39. Compressors We Use Exterior mounted unit with sorbent filters 28

40. Storage and Maintenance Airline Respirators Store facepiece and regulator in clean, dry place. Coil up hose and store in protected area to prevent damage. Clean as needed before storage – especially the inside of the facepiece. Inspect facepiece and hose for damage and replace as needed. 29

41. Supplied air respirator repairs Keep spare parts available. Tag damaged respirators to prevent use. Repair of SCBA valves, regulators or alarms can only be done by manufacturer’s trained person. 30

42. Dust Masks • May be worn for comfort • Must be replaced when breathing becomes difficult; smell/taste contaminants; experience distress; anything abnormal • Properly dispose of mask by cutting straps • Do not wear another person’s mask
