RESPIRATORY PROTECTION

1. RESPIRATORY PROTECTION A REFRESHER CLASS

2. Welcome to a self-guided refresher class for respirator users needing annual training.

3. To proceed with the class, you the student, are in control. Slides and text will progress with the click of the mouse. In a few cases, changes will happen automatically.Enjoy your session and learn lots!

4. As a respirator user, each year you are required to…. Complete this session and test

5. The respiratory hazards in your workplace should be evaluated by your supervisor…. At the time of hire If you are a new respirator user Before you begin working with new or different chemicals Before you begin working with the same chemicals under different conditions If any of these change, inform your supervisor

6. Respiratory Hazard Assessment Table….. Complete for each task, chemical or type of chemical Submit it to your EH&S representative

8. When evaluating respiratory hazards, your supervisor should also….. Evaluate what type of respiratory protection should be used such as Type of respirator Filter and cartridge needed How long the filter and cartridges can be used

9. Before using respirators, always evaluate the possibility of…. Using engineering controls by Opening windows or doors Using local exhaust fans or chemical fume hoods Using administrative controls by Substituting less hazardous chemical Reducing exposure time to the chemical Contracting out work Working outdoors

10. Evaluating your health is also important when using a respirator, because… Using a respirator adds stress to the cardiovascular and respiratory system. This added stress could complicate or add to some existing health conditions. Typically when using a respirator, other PPE is also used, creating additional stress on the body. To help evaluate your health risks……..

11. A medical questionnaire is required As a new respirator user Every two years or if directed differently by the physician Whenever a user’s health changes significantly

12. A respirator medical questionnaire Is confidential and only seen by the health care provider Is reviewed by a licensed health care provider Is obtained by contacting your EH&S representative or at the following L&I website: Check out L&I Website Submit your completed questionnaire in the provided self-addressed return envelope to your EH&S representative

13. Selecting a proper respirator Important things to remember! EH&S has many makes and models to try EH&S will assist in selection If you are a new user or you already use a respirator and are having problems with it, contact your EH&S representative for assistance

14. Selecting a proper respirator MORE important things to remember! Know the contaminants and their concentrations that you are being exposed to If there isn’t sufficient oxygen present (below 19.5%), supplied air respirators must be used If contaminants or their concentrations present Immediately Dangerous to Life and Health (IDLH) conditions, supplied air respirators must be used

15. Selecting a proper respirator If contaminants have poor warning properties (taste, smell, irritant), supplied air respirators must be used If you have facial hair, or can’t fit any respirator, powered air purifying helmet units can be used whenever a negative pressure respirator can be used.

16. Selecting filters and cartridges Pesticides Check the label for recommendation For most all pesticides the following two are recommended: Dust/mist/fumes filter No spray oils present: N-95 or P-100 (HEPA) Spray oils present: R-95 or P-100 (HEPA) Toxics Organic vapor cartridge (OV), or OV and acid gas cartridge, or multi-contaminant cartridge

17. Selecting filters and cartridges Solvents and corrosives Contact your EH&S representative or respirator manufacturer Solvents can have poor warning properties and short breakthrough times Asbestos and other respirable particles (< 10 um) P-100 (HEPA) filters Nuisance dust, mists, fumes N-95, R-95 (if contain oil), or P-100 filters

18. Testing your respirator When first selecting a respirator, finding one that has a good seal and is comfortable is done by trying a variety of respirators and passing a respirator fit test by EH&S Several factors can lead to a respirator that does not seal properly That is why a respirator fit test is required annually to help insure its fit and to review your use and care of the respirator

19. Recent dental work, and dentures Facial surgery, treatments, scars Weight loss or gain of 15 pounds or more Facial changes from aging Improper storage and maintenance of respirator Respirator straps losing their elasticity Factors that can change fit

20. A major factor that affects fit A respirator fit test cannot be given if there is facial hair present. A good fit cannot be expected the day you use your respirator when not clean shaven

21. When getting a respirator fit test: Be clean shaven in the area of the respirator seal zone that day Bring your respirator

22. Using your respirator properly Before you use your respirator, be sure you understand: Inspections (Review Respirator Inspection presentation) Donning and doffing (on and off) Maintenance Changing cartridges and filters What to do when things go wrong

23. 1. Before you use your respirator… Inspect the respirator to make sure all parts are in place, in good condition, clean, and operable Make sure cartridges and filters are the proper ones for the job and are not damaged and not expired After donning the respirator, do a positive and negative fit check -Demonstration

24. 2.How you put on your respirator is important Placing a half-face first on the bridge of the nose and tightening the upper straps first insures placement for best comfort and prevention from sliding down when perspiring Make sure the straps are adjusted evenly on both sides and the respirator is centered on the face. Using a mirror is helpful for full-face users Adjusting too tight can result in a poor fit from distortion, discomfort and pain, short use periods due to discomfort, headaches

25. How you put on your respirator is important Donning Particulate Respirators Donning Dual Cartridge Respirators Donning Half-face Respirators Donning Full-face Respirators

34. When removing your respirator Remove your contaminated gloves first If the respirator is contaminated, decontaminate the respirator or put new clean gloves on before removing your respirator

35. 3. Knowing when to change filters and cartridges is very important There must be a written change-out schedule for them in the work area so employees change them out consistently Very few cartridges have change-out indicators on them telling you when to change them For solvents and acids, contact the manufacturer or an EH&S representative

36. Changing cartridges and filters For pesticides and toxics change them after eight hours of use. If periods of use are shorter than 8 hours, add cumulative times. If periods in-between use extend 2 weeks or more reduce the eight hour total time.

37. Changing filters N-95 filters – change when breathing becomes more difficult due to resistance R-95 filters – change after eight hours of use when mists containing oil are present P-100 – change when breathing becomes more difficult due to resistance

38. 4. Taking good care of your respirator will increase its useful lifetime and insure it works properly… 

39. Keep a clean respirator Dirt particles under exhalation valves can reduce your seal/fit factor Dirt, oils, bacteria, soaps, and disinfectants left on respirators can lead to skin irritation and dermatitis so make sure your respirator is clean and well rinsed before each use It is recommended to clean after each use

40. Clean your respirator properly Clean in warm water (not to exceed 100o F) Use a mild detergent Wash with a soft sponge (brush if resistant)

41. Clean your respirator properly Dry the respirator with a lint free cloth Or hang in a clean area until dry Package it up as soon as it is dry. Do not leave hanging out Inspect the respirator after re-assembly Review the Respirator Inspection presentation

42. Repair Replace worn and defective parts with parts ONLY for that specific respirator Do not use a respirator until all necessary repairs are completed Have readily available the most commonly needed parts for timely repair to insure a working respirator is always used

43. It makes a lot of sense to…store your respirator properly It prevents it from getting distorted, which will cause it to lose its ability to fit properly and require it to be replaced It prevents it from getting damaged It prevents it from becoming contaminated reducing the protection it can provide

44. Good storage means…. Storage in an uncontaminated area Store contaminated cartridges separate from respirator Store cartridges and respirator in clean sealed containers such as self-sealing bags or sealed plastic containers To prevent distortion,store in separate hard containers and not in tool boxes or with other items

45. Good storage also means… Storage away from heat, sun, and moisture Moisture can reduce the life of some cartridges Leaving cartridges unsealed can reduce their useful life

46. When things go wrong

47. If you experience… Warning signs of taste, smell, irritation, cough Medical symptoms such as difficulty in breathing, shortness of breath, chest pain, over exertion Signs and symptoms of exposure to contaminants

48. Get out of area to fresh air and remove respirator Get out of area to fresh air and remove respirator Get out of area to fresh air and remove respirator Get out of area to fresh air and remove respirator Get out of area to fresh air and remove respirator

50. What to check and do… Inspect respirator Change cartridges or filters Red-don respirator and do positive and negative fit checks to your satisfaction Re-enter and if conditions persist, exit and notify your supervisor Address medical and exposure symptoms and inform supervisor

51. Why is it important to make sure your fit is good, and that you use and maintain the respirator properly?

52. So that your respirator can provide the level of protection it is designed to give…

53. If you don’t do these things You operate with a false sense of protection and open yourself to: Chronic exposures you never know about Acute exposures that you will know about later- after it’s too late for protection

54. Potential hazards you could be exposed to include… Toxics where acute or chronic exposure could result in systemic poisoning, illness, organ disfunction, sensitization,or death Corrosives (acids), which can cause temporary or permanent tissue damage in the respiratory system Carcinogens & particulates, which can lead to cancer or other respiratory illnesses respectively Allergens that promote illness, allergic reaction, reduced productivity, & sensitization

55. Using respiratory protection makes it possible for you to work safely
