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

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
