1 Respiratory Protection Personal Protective Clothing EPA Levels of Protection Site 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/yd 2 Polypropylene Substrate Tychem® CPF 2 –1.5 oz/yd 2 Non-Woven Substrate Tychem® CPF 3 –2.0 oz/yd 2 Polypropylene Substrate Tychem® CPF 4 –2.3 oz/yd 2 Polypropylene Substrate

6 Chemical Protective Clothing Tychem® BR –2.3 oz/yd 2 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/yd 2 Polypropylene Substrate Tychem® Responder® CMS –Tychem® Responder® Designed for Weapons of Mass Destruction (WMD)

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

9 Selection of CPC & Gloves Degradation – NR, P, F, G, E Penetration – Seams, Holes, Zippers Permeation - µg/cm 2 /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 –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: (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 Type of Respirator Quarter Mask Half Mask Full Face- piece Helmet Or Hood Loose- Fitting Facepiece Air-Purifying Respirator (APR) Powered Air- Purifying Respirator (PAPR) * or

18 Air-Supplied Respirator Assigned PFs Type of Respirator Half Mask Full Face- Piece Helmet or Hood Loose- Fitting Face- Piece Supplied Air Demand Mode Continuous Flow Pressure Demand */ SCBA Demand Mode Pressure Demand , ,

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

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 Highest Level of Protection Inhalation Hazard and Skin Hazard Fully Encapsulating Suit Supplied Air Respirator

24 Level B Inhalation Hazard –Unknown/IDLH/O 2 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 Air-Purifying Respirator (APR) Protective Clothing May or May Not Be Required

26 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 Site Control

29 Example of Contamination Reduction Zone Decon Line 1. Contaminated Equipment Drop 2. Remove Tape 3. Remove Outer Gloves 4. Remove Outer Booties 5. Remove SCBA Backpack (Keep Facepiece On) 6. Remove Suit 7. Remove Respirator Facepiece 8. Remove Inner Glove
