MIL-HDBK-1027/1B
systems, those whose downtime would affect a large portion of
the training, should be designed with parts totaling full
capacity, e.g., two 50 percent fans or two 50 percent pumps.
Then while a piece of equipment is not operating and being
repaired, the second piece of equipment can be carrying 50
percent of the load. In all cases, critical equipment should be
designed to provide as much reliability and maintainability as
possible.
2.2.2.2
Emergency Power. Emergency power is generally not a
requirement for firefighting facilities. The fuel and CO2
systems are required to be failsafe, shutting off fuel and CO2
when electrical power is lost. Without a continuous source of
fuel, there can be no fire, because there is no combustible
material inside a training structure. For this reason the
propane entry station consisting of the "block and vent"
(Appendix J, Figure J-2) should be located outside of the
training structure.
The availability of electricity at most training
facilities is reliable enough that periodic outages will not
adversely affect training. In the event of electrical power
outage at a trainer, provide a battery backup annunciation and
alarm at the 24-hour duty desk and at the instructor's station.
Provide capability to silence the alarm at both locations.
2.2.2.3
Emergency Water. Emergency water should be water
supplied under sufficient pressure to fight fires without the
use of electrical energy. Water flow tests should be performed
to determine the adequacy of the water supply system. A
separate emergency water system is not necessary for the 19F
series trainers for the same reasons stated above under
emergency power. The Navy's portable gasoline powered P-250
pumps and the Municipal Fire Department are available for
non-trainer structure fires.
2.2.2.4
Lightning Protection. As a minimum, the requirements
of NFPA 78, Lightning Protection Code, should be followed.
Lightning protection is not required for the propane tanks.
2.2.2.5
Lighting. The fenced-in grounds and parking area
around the firefighting facility should be lighted to provide
general security.
