Sensitivity Check Protocol
CautIon: Prior to compressing the bulb, ensure the smoke
tube tip is 36 inches or more away from the test
subject’s face and NOT aimed in the direction of the
test subject’s face.
8. Slowly and gently compress the bulb at a controlled, uniform,
steady rate until a small, weak, dilute stream of irritant smoke
is produced that is the absolute minimum necessary to elicit a
response from the test subject being tested.
9. Immediately stop compressing the bulb and release
the partially compressed bulb. No additional smoke is to
be generated.
10. The test subject shall stand approximately 36 inches away from
the cloud of smoke.
11. The test subject shall extend his or her arm to the edge of the
smoke cloud with palm facing upward.
12. Keeping his or her eyes closed, the test subject shall gently
and slowly wave a small, dilute portion of the smoke toward
his or her breathing zone using the fingertips of his or her
outstretched hand.
13. Keeping his or her eyes closed, the test subject shall sample
a slight, weak, dilute whiff of smoke by taking a small, weak,
shallow, and short duration sniff of smoke.
14. The test subject shall then immediately step away from the
smoke into clean, fresh air.
15. The trained, qualified, professional test administrator shall
advise the test subject when the test subject is away from the
smoke. The administrator shall then instruct the test subject to
open his or her eyes.
