  1. Respiratory Protection HS 432

  2. OSHA (29 CFR 1910.132) "Protective equipment … shall be provided, used, and maintained in a sanitary and reliable condition whenever it is necessary by reason of hazards of processes or environment, chemical hazards, radiological hazards, or mechanical irritants encountered in a manner capable of causing injury or impairment in the function of any part of the body through absorption, inhalation, or physical contact."

  3. Control Methods

  4. Hierarchy of Control • Engineering • Administration • Personal protective equipment (PPE)

  5. PPE • Personal protective equipment • You must be trained in use and demonstrate understanding • Respirators • Gloves • Eye and face protection • Chemical-resistant clothing

  6. The Occupational Safety & Health Administration (OSHA) requires employers to provide employees with PPE when there's a risk of exposure to various hazards OSHA does more than require employers to provide PPE. The agency also requires employees to USE the PPE that's provided.

  7. Some people seem to think PPE is optional—or just too much trouble OSHA requires it, and so does ABC Corporation Since it exists to protect you, you shouldn't consider PPE any more trouble than putting on gloves on a day when the temperature falls below freezing or wearing sunglasses when the summer sun is shining in your eyes.

  8. Written PPE program • Protect the wearer • Prevent injury • Hazard identification • Medical monitoring • Environmental surveillance • Selection • Use • Maintenance • Decontamination • Training 3a

  9. PPE program review and evaluation • Reviewed at least annually 4a

  10. Steps In Choosing Respiratory Equipment • Identification of hazard • Evaluation of hazard • Selection of proper respiratory • equipment by a qualified • professional

  11. Respiratory Equipment • Negative Pressure • Positive Pressure • Tight Fitting Facepiece • Loose Fitting Facepiece + + _ + _ + _ + _ + _ _ _

  12. Tight Fitting Facepieces • If the respirator has a tight fitting facepiece, • the wearer must be clean shaven

  13. Protection Factors Maximum Protection Permissible Exposure = Factor X Exposure Concentration {PF} Limit {PEL} Protection Factor Respirator Type • Dust Mask • Quarter Face APR • Half Face APR • Full Face APR • PAPR • SCBA/Pressure Demand 1 2.5 5 25 50 5,000

  14. Types Of Respiratory Equipment • Air Purifying {APR} • Air Supplying

  15. Air Purifying Respirators • Requirements For Use • Contaminant Must Be Known • Concentration Of Contaminant Must Be Known • Contaminant Must Have Adequate Warning Properties WARNING Respiratory Protection Needed!!

  16. Air Purifying Respirators • Limitations • Protection Only For Hazards Listed On Cartridge • Do Not Protect Against Temperature Extremes • Do Not Protect Against Oxygen Deficiency

  17. CARTRIDGE COLORS Color Assigned: Contaminant: White White With Green Stripe White With Yellow Stripe Black Green Green With White Stripe Acid Gases Hydrocyanic Acid Gas Chlorine Gas Organic Vapors Ammonia Gas Acid Gases + Ammonia Gases

  18. CARTRIDGE COLORS Color Assigned: Contaminant: Yellow Yellow With Blue Stripe Brown Purple {Magenta} Canister Color For The Containment With Gray Stripe Red With Gray Stripe Acid Gases +Organic Vapors Hydrocyanic + Chloropirin Acid/Ammonia Gas + Organic Radioactive Materials {HEPA} Particulates {Dusts, Fumes, Mists, Fog Or Smoke} All Of The Above Listed Atmospheric Contaminants

  19. Air Purifying Respirators • Types • Disposable • Quarter Face • Half Face • Full Face • Powered Air Purifying {PAPR}

  20. Disposable Respirators • Simple Filtering Devices • Snug Fit Is Required

  21. Powered Air Purifying Respirators • Same Limitations As Other Air Purifying Respirators • Provide A Higher Protection Factor Due To Positive Pressure In The Facepiece

  22. Supplied Air Respirators • Types • Airline • Self Contained Breathing Apparatus {SCBA }

  23. Supplied Air Respirators • Cannot provide protection against every type of hazard • Inspect before every use • Clean after every use • Store properly

  24. Fit Testing • QUALITATIVE • Negative pressure check • Positive pressure check • Banana oil/irritant smoke test

  25. Rainbow Passage • When the sunlight strikes raindrops in the air, they act like a prism and form a rainbow. The rainbow is a division of white light into many beautiful colors. These take the shape of a long, round arc, with its path high above and its two ends beyond the horizon. There is, according to legend, a boiling pot of gold at one end. People look, but no one ever finds it. When a man looks for something beyond reach, his friends say he is looking for the pot of gold at the end of the rainbow.

  26. Fit Testing • QUANTITATIVE • Concentration of a test aerosol is measured inside and outside the respirator. • Coutside/Cinside is compared to theoretical protection factor of respirator to check if it fits the wearer adequately.
