Respiratory Protection

  1. 1. Respiratory Protection
  2. 2. Why respiratory protection is necessary <ul><li>Air contaminants/hazardous atmospheres come from a variety of sources </li></ul><ul><ul><li>dusts </li></ul></ul><ul><ul><li>aerosol mists </li></ul></ul><ul><ul><li>metal fumes </li></ul></ul>1a
  3. 3. <ul><li>Air contaminants/hazardous atmospheres come from a variety of sources </li></ul><ul><ul><li>evaporated vapors </li></ul></ul><ul><ul><li>released gases </li></ul></ul><ul><ul><li>oxygen-deficient atmospheres </li></ul></ul>Why respiratory protection is necessary 1b
  4. 4. <ul><li>Many operations generate air contaminants </li></ul><ul><ul><li>filling bins with flour </li></ul></ul><ul><ul><li>degreasing metal parts </li></ul></ul><ul><ul><li>spraying operations </li></ul></ul><ul><ul><li>welding </li></ul></ul>Why respiratory protection is necessary 1c
  5. 5. <ul><li>Find out how much contaminant is in the air </li></ul><ul><li>Test the air to find out what the exposures are </li></ul>Why respiratory protection is necessary 1d
  6. 6. <ul><li>If results show an overexposure, take steps to control the hazard </li></ul><ul><ul><li>engineering controls </li></ul></ul><ul><ul><li>administrative controls </li></ul></ul><ul><ul><li>PPE </li></ul></ul>Why respiratory protection is necessary 1e
  7. 7. Respirator types <ul><li>Atmosphere-supplying </li></ul><ul><ul><li>supplied air </li></ul></ul><ul><ul><li>self-contained breathing apparatus (SCBA) </li></ul></ul><ul><ul><li>demand </li></ul></ul><ul><ul><li>positive pressure </li></ul></ul><ul><ul><li>escape-only </li></ul></ul>2a
  8. 8. Respirator types <ul><li>Air-purifying </li></ul><ul><ul><li>filter </li></ul></ul><ul><ul><li>canister or cartridge </li></ul></ul>2b
  9. 9. Respirator types <ul><li>Air-purifying </li></ul><ul><ul><li>negative pressure </li></ul></ul><ul><ul><li>powered air-purifying </li></ul></ul>2c
  10. 10. Fit, usage, and maintenance <ul><li>Employees must pass a fit test </li></ul><ul><ul><li>quantitative fit </li></ul></ul><ul><ul><li>qualitative fit </li></ul></ul><ul><li>Use the respirator as it was designed </li></ul>3a
  11. 11. <ul><li>Follow operating instructions </li></ul><ul><li>If respirators are used to enter an IDLH atmosphere: </li></ul><ul><ul><li>one trained, rescue- equipped employee must remain outside </li></ul></ul><ul><ul><li>an attendant must maintain communication contact </li></ul></ul>Fit, usage, and maintenance 3b
  12. 12. <ul><li>During interior structural firefighting </li></ul><ul><ul><li>at least 2 employees with SCBA must enter together and stay in contact with each other </li></ul></ul><ul><ul><li>at least two people trained and equipped for rescue must remain outside </li></ul></ul>Fit, usage, and maintenance 3c
  13. 13. Fit, usage, and maintenance <ul><li>A dirty, inoperative respirator will not protect you </li></ul>3d
  14. 14. Inspection, donning, doffing respirators <ul><li>Inspect respirators before each use and during cleaning </li></ul><ul><li>Inspect SCBAs monthly and keep cylinders fully charged </li></ul>4a
  15. 15. Inspection, donning, doffing respirators <ul><li>Emergency-use respirators: </li></ul><ul><ul><li>inspect monthly </li></ul></ul><ul><ul><li>tags must show inspection results </li></ul></ul><ul><li>Follow manufacturer’s instructions for donning/doffing equipment </li></ul>4b
  16. 16. Inspection, donning, doffing respirators <ul><li>Perform seal checks after donning respirator </li></ul><ul><ul><li>positive pressure test </li></ul></ul><ul><ul><li>negative pressure test </li></ul></ul><ul><ul><li>review Appendix B-1 </li></ul></ul><ul><li>Never enter a work area without a good respirator seal </li></ul>4c
  17. 17. Cleaning, maintenance, and storage <ul><li>Respirators must be cleaned to remove contaminants/prevent irritation </li></ul><ul><li>Shared respirators must be cleaned before each use </li></ul>5a
  18. 18. Cleaning, maintenance, and storage <ul><li>Emergency-use respirators must be cleaned after each use </li></ul><ul><li>Review Appendix B-2 for cleaning/disinfecting instructions </li></ul><ul><li>Only use manufacturer’s replacement parts </li></ul>5b
  19. 19. Cleaning, maintenance, and storage <ul><li>Storage helps prevent respirators from: </li></ul><ul><li>Damage </li></ul><ul><li>Contamination </li></ul><ul><li>Dust </li></ul><ul><li>Sunlight </li></ul><ul><li>Temperature extremes </li></ul><ul><li>Excessive moisture </li></ul><ul><li>Chemicals </li></ul><ul><li>Deformation of the facepiece </li></ul>5c
