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
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
OSHA’s respiratory standard (29 CFR 1910.134) is mandatory
NIOSH approved disposable particulate respirators are the minimum
level of respiratory protection that should be worn
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
Quantitative
Qualitative
Both are acceptable. Which is better?

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

Particulate filters are
further classified base
on efficiency
• 95 percent, designated 95
• 99 percent, designated 99
• 99.97 percent, designated 100 (HEPA filter)

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

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.

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
