in the bilge fire building, to minimize control wiring lengths.
No building should be further than 18 m horizontally from the

structures are in Appendix C. The 19F3 and 19F3B devices are
housed in four structures: the bilge fire building,
galley/berthing building, and two pit fire buildings.
126.96.36.199 Bilge Fire Building (19F3 and 19F3B). The bilge fire
building should have interior dimensions of 9144 mm by 9144 mm
with a ceiling height of 4600 mm. This area should house a
generalized mockup of a shipboard engineering space to provide
realism while exposing students to a major Class "B" bilge fire.
Staging should be on the roof and at one ground level entrance.
One topside entrance should include a dogged watertight door
built into a vestibule, leading to an inclined ladder. Provide
reinforcing of the landing to prevent swaying when six students
with fire hoses are descending. The ladder should have a 1550
mm long landing midway down its length. At bilge area 1, the
dimension from the corner to the shield should be 3124 mm clear.
At bilge area 2, the dimension from the corner to the escape
truck liner should be 7163 mm clear.
a) The bilge fire building should have a second
topside entrance by way of a watertight hatch and emergency
b) A ground level entry with staging area should be
located under the vertical ladder in the bilge fire building.
The staging area should include a 4572 mm by 4572 mm OBA locker
with a ground level entry. The design of the OBA locker should
be similar to a repair locker.
c) A 1219 mm wide
walkway should be provided around
the exterior of the building
to allow for emergency egress and
to allow exterior viewing of
the training scenario. Two sets of
stairs should provide access
to the roof.
