Animal Disease Response Training Personal Protective Equipment August 2010 AWR 206-1
Animal Disease Response Training 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.
Animal Disease Response Training 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.
Animal Disease Response Training Enabling Learning Objectives 2-1Describe the process and authority used to determine proper levels of protection mandated during response to an animal disease incident. 2-2Identify factors to consider while working in PPE. 2-3Identify the various components of PPE used in an agriculture emergency. 2-4Identify physiological and psychological stressors that can affect users of all levels of PPE.
Animal Disease Response Training Choice of respiratory and dermal protection depends upon? Specific disease agent Conditions in which equipment is worn Activities and exposure level of personnel
Animal Disease Response Training 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
Animal Disease Response Training Personal Protective Equipment Overview Body Hand Eye Foot Respiratory
Animal Disease Response Training Body Protection Permeable suits Impermeable suits
Animal Disease Response Training Hand Protection Biological and Chemical Hazards Polyvinyl chloride (PVC) Nitrile Neoprene Latex Mechanical Hazards Leather/work glove
Animal Disease Response Training Eye protection should always be worn when dealing with biological and chemical materials Must meet ANSI Z-87.1
Animal Disease Response Training 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
Animal Disease Response Training What are the required components of a respiratory protection program? Written program Training Medical evaluation Fit testing Respirator maintenance program NIOSH approved disposable particulate respirators are the minimum level of respiratory protection that should be worn OSHAs respiratory standard (29 CFR ) is mandatory
Animal Disease Response Training Respirators can be divided into two classes Air supplying Air purifying Which offers more protection?
Animal Disease Response Training Oxygen-Deficient Atmospheres Present in pits, silos and tanks Normal air contains 20.8% O % O 2 in air is deficient –displaced by another gas –consumed by combustion –changed by reaction
Animal Disease Response Training The following respirators are not safe in an oxygen-deficient environment!
Animal Disease Response Training Respirator type may be determined by pressure inside the mask when inhaling Negative pressure Positive pressure Which offers more protection?
Animal Disease Response Training OSHA requires workers pass a fit test before wearing a respirator on the job PortaCount Quantitative Fit Testing System Courtesy TSI, Inc. Quantitative Qualitative Allegro Complete Smoke Fit Test Kit Photo Courtesy Gemplers Both are acceptable. Which is better?
Animal Disease Response Training Particulate filters are classified based on resistance to oil
Animal Disease Response Training Particulate filters are further classified base on efficiency 95 percent, designated percent, designated percent, designated 100 (HEPA filter)
Animal Disease Response Training Acceptable for animal disease response Nine categories of particulate respirators NRP
Animal Disease Response Training Respirators can be further divided based on facial coverage Full-face Half-face Which offers more protection?
Animal Disease Response Training Air Purifying Respirators Filter out dusts and vapors Must have correct color-coded cartridge Must be NIOSH-approved ColorTypeProtection against Magenta, purple High Efficiency Particulate Air (HEPA) Dust particles, viruses, bacteria BlackOrganic vaporSolvents YellowAmmoniaAnimal wastes
Animal Disease Response Training What is the proper order of Fitting Instructions? Must be followed each time respirator is worn
Animal Disease Response Training User seal checks must be performed before each use Only after passing a fit test To ensure a good respirator-to-face seal Positive pressure respirators must be checked in negative mode If you CANNOT achieve a proper fit DO NOT enter the contaminated area.
Animal Disease Response Training 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.
Animal Disease Response Training Integrated Protection Combining Components of PPE Level A Level B Level C Level D
Animal Disease Response Training Personal Protective Equipment Level 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
Animal Disease Response Training Personal Protective Equipment Level D Coverall –Hooded or two-piece Gloves Boots/shoes –disposable covers Safety glasses Comfort mask
Animal Disease Response Training What are Physiological Stressors? Lack of physical fitness Age Dehydration Obesity Work Rate Ambient Temperature
Animal Disease Response Training What are Psychological Stressors? Claustrophobia Anxiety or panic Situational traumatic stress
Animal Disease Response Training 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
