  1. Scope Statement This lesson provides responders with information regarding procedures for selection, inspection, and safe use of appropriate personal protective equipment (PPE). Varying styles and levels of PPE appropriate for animal disease incidences and the associated requirements will be introduced. The lesson also discusses selection of task specific PPE, donning and doffing, and safety issues associated with wearing PPE.

  2. Terminal Learning Objective Describe the proper procedures for inspection and use of personal protective equipment to ensure the safety of responders during an animal disease incident.

  3. Enabling Learning Objectives 2-1Describe the process and authority used to determine proper levels of protection mandated during response to an animal disease incident. 2-2 Identify factors to consider while working in PPE. 2-3 Identify the various components of PPE used in an agriculture emergency. 2-4 Identify physiological and psychological stressors that can affect users of all levels of PPE.

  4. Choice of respiratory and dermal protection depends upon? • Specific disease agent • Conditions in which equipment is worn • Activities and exposure level of personnel

  5. Level of Protection • Determined by animal health authorities in cooperation with public health officials • State Veterinarian • Area Veterinarian In Charge (USDA-AVIC) • Federal, state, tribal public health officials • Assured by safety officers to be appropriate

  6. Personal Protective Equipment Overview • Body • Hand • Eye • Foot • Respiratory

  7. Body Protection Permeable suits Impermeable suits

  8. Hand Protection Biological and Chemical Hazards Polyvinyl chloride (PVC) Nitrile Neoprene Latex • Mechanical Hazards • Leather/work glove

  9. Eye protection should always be worn when dealing with biological and chemical materials Must meet ANSI Z-87.1

  10. Foot protection should always be worn • Shoes should completely cover and protect the foot • Impermeable shoe covers can provide barrier protection to shoes or boots

  11. What are the required components of a respiratory protection program? • Written program • Training • Medical evaluation • Fit testing • Respirator maintenance program OSHA’s respiratory standard (29 CFR 1910.134) is mandatory NIOSH approved disposable particulate respirators are the minimum level of respiratory protection that should be worn

  12. Air purifying Respirators can be divided into two classes • Air supplying Which offers more protection?

  13. Oxygen-Deficient Atmospheres • Present in pits, silos and tanks • Normal air contains 20.8% O2 • ≤ 19.5% O2 in air is deficient • displaced by another gas • consumed by combustion • changed by reaction

  14. The following respirators are not safe in an oxygen-deficient environment!

  15. Positive pressure Respirator type may be determined by pressure inside the mask when inhaling • Negative pressure Which offers more protection?

  16. PortaCount Quantitative Fit Testing System Courtesy TSI, Inc. OSHA requires workers pass a fit test before wearing a respirator on the job Quantitative Qualitative Both are acceptable. Which is better? Allegro Complete Smoke Fit Test Kit Photo Courtesy Gempler’s

  17. Particulate filters are classified based on resistance to oil

  18. Particulate filters are further classified base on efficiency • 95 percent, designated 95 • 99 percent, designated 99 • 99.97 percent, designated 100 (HEPA filter)

  19. Nine categories of particulate respirators Acceptable for animal disease response

  20. Half-face Respirators can be further divided based on facial coverage • Full-face Which offers more protection?

  21. Air Purifying Respirators • Filter out dusts and vapors • Must have correct color-coded cartridge • Must be NIOSH-approved

  22. What is the proper order of Fitting Instructions? Must be followed each time respirator is worn

  23. User seal checks must be performed before eachuse • Only afterpassing a fit test • To ensure a good respirator-to-face seal • Positive pressure respirators must be checked in negative mode • If you CANNOTachieve a proper fit DO NOT enter the contaminated area.

  24. Powered Air-Purifying Respirator (PAPR) PAPRs use a fan to convey contaminated air through a HEPA filter that removes contaminants and supplies purified air to the facepiece worn by the responder.

  25. Integrated ProtectionCombining Components of PPE Level D Level A Level C Level B

  26. Personal Protective EquipmentLevel C • Air-purifying respirator (N-95) • One-piece coverall with apron • Hooded two-piece splash suit • Gloves, inner chemical-resistant • Gloves, outer chemical-resistant • Boots or booties • Safety glasses or goggles

  27. Personal Protective Equipment Level D • Coverall • Hooded or two-piece • Gloves • Boots/shoes • disposable covers • Safety glasses • Comfort mask

  28. What are Physiological Stressors? • Lack of physical fitness • Age • Dehydration • Obesity • Work Rate • Ambient Temperature

  29. What are Psychological Stressors? • Claustrophobia • Anxiety or panic • Situational traumatic stress

  30. Summary • Many factors determine PPE in an agriculture emergency • Tasks performed • Conditions which PPE is worn • Specific disease agent involved • Proper procedures for inspection and use of PPE critical for reducing spread of disease
