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
2-1 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.

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 Impermeable suits Permeable suits

8 Hand Protection Polyvinyl chloride (PVC) Leather/work glove Nitrile
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 ) is mandatory NIOSH approved disposable particulate respirators are the minimum level of respiratory protection that should be worn

12 Respirators can be divided into two classes
Air supplying Air purifying 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 Respirator type may be determined by pressure inside the mask when inhaling
Negative pressure Positive pressure Which offers more protection?

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

17 Particulate filters are classified based on resistance to oil
Not resistant to oil R Resistant to oil Good for one shift in oil mist P Oil Proof Good for prolonged use in mist

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
100 99 95 Acceptable for animal disease response

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

21 Air Purifying Respirators
Filter out dusts and vapors Must have correct color-coded cartridge Must be NIOSH-approved Color Type Protection against Magenta, purple High Efficiency Particulate Air (HEPA) Dust particles, viruses, bacteria Black Organic vapor Solvents Yellow Ammonia Animal wastes

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 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.

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 Protection Combining Components of PPE
Level A Level B Level C Level D EPA designates four levels Protect responders Increase biosecurity

26 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

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
