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
2-1 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.
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

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
OSHA’s respiratory standard (29 CFR 1910.134) 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% O2
• ≤ 19.5% O2 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

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 95• 99 percent, designated 99• 99.97 percent, designated 100 (HEPA filter)
Animal Disease Response Training
Acceptable for animal disease response
Nine categories of particulate respirators
N R P
100 100 100
99 99 99
95 95 95
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
Color Type Protection against
Magenta, purple
High Efficiency Particulate Air (HEPA)
Dust particles, viruses, bacteria
Black Organic vapor Solvents
Yellow Ammonia Animal 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 ProtectionCombining Components of PPE
Level A Level B Level C Level D
Animal Disease Response Training
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
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
