temperature. The unit requires one-half hour at the start to
attain operating temperature. When smoke is required, the
chemical is injected into the hot air and ducted to the proper
location. The building ventilation should remain on even during
the application of smoke. The bypass duct should discharge into
the ventilation system or be controlled so that no artificial
smoke can exit through it. Different smoke generation rates are
obtained by relieving air before the chemical is injected into
it.
d) The smoke generator should be powered by propane
and electricity and located on the ground adjacent to the
training structure.

Gas Chamber
2.7.1
General. Use the gas chamber to provide chemical
warfare countermeasures training; it is not part of the 19F and
21C12 series firefighting structure. However, the gas chamber
should usually be provided with the 19F5 facility. The chemical
agent to be used for training is tear gas. Use the gas chamber
to train 1 class of 100 personnel at a time, 2 to 3 classes per
day, and 20 classes per week.
2.7.2
Training. Recruits and instructors will enter into
the gas chamber wearing the MCU2/P gas masks. Prior to their
entrance in the chamber, tear gas is made on a hot plate and is
subsequently exposed to the recruits as they remove their gas
masks. When gas training is complete, the recruits and
instructors march out of the chamber to an area where they can
get fresh air. After completion of gas training, an instructor
opens the emergency exit/vent doors and energizes the exhaust
system to exhaust the tear gas-laden air from the gas chamber.
During winter, the instructor will deenergize the heating system
prior to energizing the exhaust system. When tear gas has been
removed from the gas chamber, the exhaust system will be
deenergized and the heating system will be energized, as
required. After each use, the gas masks will be sterilized by
the recruits by dipping or wiping the masks with a 2 percent
iodine and 98 percent water solution. The masks are then rinsed
or wiped with water and wiped dry.
