MIL-HDBK-1027/1B
lockable post indicator type valve, and should be high enough
above the outlet invert so the influent can fall even in
freezing weather. The inlet should be baffled. Both inlet and
outlet should terminate inside the chamber with a pipe flange
and sufficient room for a future pipe fitting. The outlet
should be a dip tube which draws from the bottom of the chamber.
A running trap should be provided in the outlet line adjacent to
the chamber (see Appendix A, Figure A-16 for separation chamber
detail).
b) "NO SMOKING" signs should be posted facing all
directions around the separation chamber since it is a source of
propane.
c) No traps should be provided in the piping leading
from the crawl spaces. Floor drains leading from other spaces
in the training structure should have vented traps or should tie
into the wastewater line upstream of the separation chamber
running trap. This precaution will prevent propane migration
through the piping.
3.2.10
Fireplace Compartment Dimensions. Dimensions given
for fireplace compartment sizes are inside clear dimensions.
These inside clear dimensions are critical and should be
maintained; allowable tolerance should be plus or minus 6.35 mm
maximum. For example, if a fireplace compartment has refractory
coatings and steel plate liners on the walls, then the inside
clear dimensions are from liner to liner of the walls.
3.3
Repair or Crash Lockers. Each structure, except the
21C12 and 21C12A trainers, should have at least one repair
locker to house the paraphernalia required for firefighting.
Unless indicated otherwise, repair lockers should be 3048 mm on
a side with a 2438 mm sloping roof and gutter. Repair lockers
should have natural ventilation at floor and roof and should
have a floor drain. Hollow metal doors should be used on repair
locker entries. The following repair locker equipment should be
provided by the respective training school:
a) Damage control plotting board to track status of
the fire and extinguishment process
b)
OBA canisters and OBA's
