(2)
An emergency air breathing "SCOTPAK."
h) Doors for the spaces containing the CO2 recharging
system should be provided with panic hardware.
4.5
Halon. Halon is an invisible gas which is used in the
Navy community. Where it is called for in the training
structure it should be simulated and necessary equipment should
be provided by the device contractor. No facility services are
required. The Halon simulator should look like a shipboard
installation but there should be no pressurized containers
inside the structure. Halon is now limited by the Navy due to
possible ozone depletion.
4.6
Aqueous Potassium Carbonate (APC). APC is a type of
extinguishment that is used as a fixed range guard system on
kitchen exhaust hoods. It should be simulated on the deep fat
fryer fireplace by the use of a water spray.
4.7
Nozzles. Hose end nozzles used for firefighting
training should be provided by the user as collateral equipment.
The preferred water fog nozzle is NAVSHIPS Dwg. 805-860089.
4.8
Oxygen Breathing Apparatus (OBA). OBA are used by the
Navy to protect firefighters from the toxicity of the products
of combustion. They contain a replaceable cartridge. Oxygen is
produced by chemical reaction in the cartridge. The OBA's
should be stored in repair lockers associated with each
structure. Chemicals in the spent cartridge should be
completely finished producing oxygen prior to disposal. This is
done by letting them set in the air a minimum of one hour, then
recapping them and wrapping them in double poly bags. Wrapped
cartridges are then stored in drums to be hauled away as
hazardous waste.
4.9
Hose Stations. In the 80 mm service pipe supplying
each hose station, provide a shutoff valve so the instructor can
disable the station. The valve should be out of sight of the
trainee where possible but in a location convenient to the
instructor. The instructor's shutoff valve should be a 80 mm
commercial ball valve with a locking handle.
