1Scope StatementThis 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.
2Terminal 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.
3Enabling Learning Objectives 2-1 Describe 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.
4Choice of respiratory and dermal protection depends upon? Specific disease agentConditions in which equipment is wornActivities and exposure level of personnel
5Level of ProtectionDetermined by animal health authorities in cooperation with public health officialsState VeterinarianArea Veterinarian In Charge (USDA-AVIC)Federal, state, tribal public health officialsAssured by safety officers to be appropriate
8Hand Protection Polyvinyl chloride (PVC) Leather/work glove Nitrile Biological and Chemical HazardsPolyvinyl chloride (PVC)NitrileNeopreneLatexMechanical HazardsLeather/work glove
9Eye protection should always be worn when dealing with biological and chemical materials Must meet ANSI Z-87.1
10Foot protection should always be worn Shoes should completely cover and protect the footImpermeable shoe covers can provide barrier protection to shoes or boots
11What are the required components of a respiratory protection program? Written programTrainingMedical evaluationFit testingRespirator maintenance programOSHA’s respiratory standard (29 CFR ) is mandatoryNIOSH approved disposable particulate respirators are the minimum level of respiratory protection that should be worn
12Respirators can be divided into two classes Air supplyingAir purifyingWhich offers more protection?
13Oxygen-Deficient Atmospheres Present in pits, silos and tanksNormal air contains 20.8% O2≤ 19.5% O2 in air is deficientdisplaced by another gasconsumed by combustionchanged by reaction
14The following respirators are not safe in an oxygen-deficient environment!
15Respirator type may be determined by pressure inside the mask when inhaling Negative pressurePositive pressureWhich offers more protection?
16OSHA requires workers pass a fit test before wearing a respirator on the job QuantitativeQualitativePortaCount Quantitative Fit Testing SystemCourtesy TSI, Inc.Allegro Complete Smoke Fit Test Kit Photo Courtesy Gempler’sBoth are acceptable. Which is better?
17Particulate filters are classified based on resistance to oil Not resistant to oilRResistant to oilGood for one shift in oil mistPOil ProofGood for prolonged use in mist
18Particulate filters are further classified base on efficiency 95 percent, designated 9599 percent, designated 9999.97 percent, designated 100 (HEPA filter)
19Nine categories of particulate respirators 1009995Acceptable for animal disease response
20Respirators can be further divided based on facial coverage Full-faceHalf-faceWhich offers more protection?
21Air Purifying Respirators Filter out dusts and vaporsMust have correct color-coded cartridgeMust be NIOSH-approvedColorTypeProtection againstMagenta, purpleHigh Efficiency Particulate Air (HEPA)Dust particles, viruses, bacteriaBlackOrganic vaporSolventsYellowAmmoniaAnimal wastes
22What is the proper order of Fitting Instructions? Must be followed each time respirator is worn
23User seal checks must be performed before each use Only after passing a fit testTo ensure a good respirator-to-face sealPositive pressure respirators must be checked in negative modeIf you CANNOT achieve a proper fit DO NOT enter the contaminated area.
24Powered 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.
25Integrated Protection Combining Components of PPE Level ALevel BLevel CLevel DEPA designates four levelsProtect respondersIncrease biosecurity
26Personal Protective Equipment Level C Air-purifying respirator (N-95)One-piece coverall with apronHooded two-piece splash suitGloves, inner chemical-resistantGloves, outer chemical-resistantBoots or bootiesSafety glasses or goggles
27Personal Protective Equipment Level D CoverallHooded or two-pieceGlovesBoots/shoesdisposable coversSafety glassesComfort mask
28What are Physiological Stressors? Lack of physical fitnessAgeDehydrationObesityWork RateAmbient Temperature
29What are Psychological Stressors? ClaustrophobiaAnxiety or panicSituational traumatic stress
30Summary Many factors determine PPE in an agriculture emergency Tasks performedConditions which PPE is wornSpecific disease agent involvedProper procedures for inspection and use of PPE critical for reducing spread of disease
