MIL-HDBK-1027/1B
Fifteen-lb CO2, 8.2 kg PKP, and 9.46 L AFFF
extinguishers should also be used. Since the use rate for
extinguishers will be high, ready storage is located in the
staging area. After beneficial occupancy, instructors should
locate the extinguishers in the trainer compartment.

Notes: 1. Propane demand is based on a gas pressure at the
bilge and hull fires of 14 kPa.
2. The design propane demand for the building is
96 L/s.
3. It was assumed that although there are more fires in
the 2071 course they do not burn as long; therefore,
the total consumption 217 796 L/class, based on the
2071 course, is the design maximum.
