10. The administrator shall not conduct a Sensitivity Check of
more than one test subject at a time.
11. The Sensitivity Check shall be conducted in a calm, windless,
and well-ventilated area. No form of hood, chamber, or other
enclosure is to be used. Do not perform the Sensitivity Check
in a confined space or in an area with moving air that may
blow the smoke toward the test subject or administrator. In
the area where the Sensitivity Check is performed, the ground
surface or deck surface or floor surface shall be flat and level,
reasonably smooth, and free of holes and obstructions.
12. The administrator shall be careful to recognize that each
test subject’s sensitivity and response to irritant smoke
vary. Sensitivity and response vary based upon size, weight,
heredity, health, age, and other factors. Some test subjects
may respond to a far greater degree than others to a small
amount of irritant smoke. The administrator shall consider the
test subject’s unique characteristics, including but not limited
to, size, weight, heredity, health, allergies, medical history,
age, and other relevant factors as well as sensitivity to irritant
smoke before generating a small, dilute stream of irritant
smoke that is the absolute minimum concentration of irritant
smoke necessary to elicit a response from the test subject.
13. The administrator and the test subject shall take precautions
to minimize the test subject’s and administrator’s exposure to
smoke. The test subject shall only be exposed to a small, weak,
dilute concentration of smoke that is the absolute minimum
necessary to elicit a response.
14. Prior to commencing the Sensitivity Check, the administrator
shall instruct the test subject:
A. That the smoke is irritating to the eyes, nasal passageway,
respiratory tract, and lungs.
