radiation. The heating equipment should be designed for water
cleaning by hose and should also be able to withstand the
accumulation of tear gas powder.
During tear gas training, when the recruits are
entering the gas chamber room, the heating will be turned off by
the instructor. When recruits are in the gas chamber, the
instructor will turn the heating systems back on. The exhaust
system will be off throughout the gas training. After
completion of gas training, the instructor will turn the heating
system off in the gas chamber room, open doors, and energize the
exhaust system to rid the gas chamber of tear gas. After
exhausting the tear gas out of the chamber, the instructor will
turn the exhaust system off and energize the heating system.
