  1. Respiratory ProtectionPersonal Protective ClothingEPA Levels of ProtectionSite Control/Decontamination Larry Wong, CIH University of California Office of the President

  2. Personal Protective Equipment (PPE) • Head Protection • Hard Hat • 5 Year Lifespan • Face and Eye Protection • Goggles, Safety Glasses, Face Shield • Foot Protection • Safety Shoes, Protective Booties • Hand Protection • Gloves • Body Protection • Chemical Protective Clothing, Apron

  3. Use of PPE • Must Meet ANSI Standards • Training for PPE User • Proper Use, Storage, Manufacturer’s Instructions • Limitations • Training Prior to Use • Clean and Sanitized • Sanitized Between Users If Skin Contact Occurs

  4. Chemical Protective Clothing • Tyvek® • Tychem® QC • Polyethylene • Tychem® SL • Saranex®-23P • 2.0 Mil Thickness • Chemrel™ • Multi-Layer Film Barrier

  5. Chemical Protective Clothing • Tychem® CPF 1 • 1.5 oz/yd2 Polypropylene Substrate • Tychem® CPF 2 • 1.5 oz/yd2 Non-Woven Substrate • Tychem® CPF 3 • 2.0 oz/yd2 Polypropylene Substrate • Tychem® CPF 4 • 2.3 oz/yd2 Polypropylene Substrate

  6. Chemical Protective Clothing • Tychem® BR • 2.3 oz/yd2 Polypropylene Substrate • Tychem® F • Proprietary Barrier Laminated to Tyvek® • 4H™ or Silvershield®

  7. Haz Mat Protective Clothing • Tychem® TK • No Permeation after 8 Hrs. for >260 Chemicals • Tychem® Responder® • 3.0 oz/yd2 Polypropylene Substrate • Tychem® Responder® CMS • Tychem® Responder® Designed for Weapons of Mass Destruction (WMD)

  8. Butyl Nitrile Neoprene 4H™ or Silvershield® Barrier™ Laminated Film Polyvinyl Chloride (PVC) Polyvinyl Alcohol (PVA) Rubber Viton® Gloves

  9. Selection of CPC & Gloves • Degradation – NR, P, F, G, E • Penetration – Seams, Holes, Zippers • Permeation - µg/cm2/Minute or Hour • Breakthrough Time – Minutes or Hours

  10. PPE Selection • Manufacturer’s Selection Charts • Manufacturer’s Fax Number • Internet • Computer Programs/CD Roms • Computer-Aided Management of Emergency Operations (CAMEO®) Program • Reference Books

  11. PPE Limitations • Affects Mobility • Hazard Around Machinery • Heat Stress • Training in Heat Illness Prevention Program • Work-Rest Cycle • Drink Fluids (8 oz. of Water) Every 30 Minutes • Shaded Work/Rest Area • Biological Monitoring (Heart Rate) • Administrative Controls

  12. Donning PPE and Gloves • Double Glove • Tape Seams

  13. Types of Respirators • Air Purifying Respirator (APR) • Air Cleaned Through Cartridge and/or Filter • Supplied Air • Pressure Demand SCBA

  14. Major Respirator Program Elements • Initial & Annual Fit-Testing • Initial & Annual Training • Determination By Physician or Licensed Health Care Professional (PLHCP) • Respirator, Cartridges, and/or Filters Must Be Approved By NIOSH (TC Number) • Replacement Parts • Cleaning, Sanitation, & Storage Program

  15. Respirator Protection Factor (PF) • PF for a Respirator • Measure of Amount of Protection the Respirator will Provide to Wearer • Revised OSHA Respirator Regulation, 29 CFR 1910.134 • Promulgated in 1998 • No Assigned PF in Original 1998 Standard • NIOSH & ANSI Z88.2 • PFs were Different

  16. Respirator Protection Factor • PF in OSHA Regulation: 1910.134(d)(3)(i)(A) • Noticed in Federal Register on August 24, 2006 • Became Effective November 22, 2006 • Cal/OSHA Respirator Regulations, Title 8 California Code of Regulations, Section 5144 • Will Adopt New OSHA Assigned Protection Factors in 2007

  17. APR Assigned Protection Factors

  18. Air-Supplied Respirator Assigned PFs

  19. APRs • Filters – Change When Difficult to Breathe • Cartridges – Change Schedule or End of Service Life Indicator (ESLI) • Annual Fit-Testing • Qualitative or Quantitative • Donning • Positive & Negative Pressure Fit-Test

  20. Limitations of APR • Adequate Oxygen • Known Contaminant • Known Concentration • Concentration <IDLH • ESLI or Change Out Schedule

  21. Pressure Demand SCBA • 30 to 60 Minutes Breathing Air • Protection Factor 10,000 • Use in Oxygen Deficient Atmosphere • Can Be Used in Unknown Contaminant/Concentration Atmospheres • Can Be Use in IDLH Atmospheres

  22. U.S. EPA Levels of Protection • Generally No “Set in Stone” One Type for Each Level (See Attachment A) • Main Difference - Type of Respiratory Protection • EPA Levels: • Level A • Level B • Level C • Level D

  23. Level A • Level A • Highest Level of Protection • Inhalation Hazard and Skin Hazard • Fully Encapsulating Suit • Supplied Air Respirator

  24. Level B • Level B • Inhalation Hazard • Unknown/IDLH/O2 Deficiency • Contaminant in Which an Air-Purifying Respirator Cannot Be Used • Supplied Air Respirator • Protective Clothing May or May Not Be Required

  25. Level C • Level C • Air-Purifying Respirator (APR) • Protective Clothing May or May Not Be Required

  26. Level D • Level D • No Respiratory Hazard - No Respirators • Protective Clothing May or May Not Be Required

  27. Site Control/Decontamination • Hot Zone - Contaminated • Contamination Reduction Zone – Removal of PPE, Decontamination of Personnel • Located Upwind from Hot Zone • Clean Zone – No Contamination

  28. Hot Zone Entry Exit Decon Line Contamination Reduction Zone Clean Zone Wind Direction Site Control
