ventilation openings at the base of these corridor enclosures on
three walls. Personnel access to the space below the corridor
floor should be by removing a grating section.
Except for the aforementioned walls, the crawl spaces
should remain open and clear. Partition walls should stop at
the training floor. Grating should be used exclusively for the
training floors in the 19F1A structure.
3.13.2.2 Ceilings. A steel barrier or false ceiling should be
provided in Compartments 1 and 2 below the second floor crawl
space to facilitate buildup of residual heat so the room stays
hot during the whole exercise. The ceiling shields the crawl
space floor above from direct radiant heat, keeping it cooler.
A clearance of approximately 310 mm should be maintained between
the barrier and the walls.
3.13.2.3 Doors and Hatches. The door type should be as shown
on the floor plan. Exterior doors on the first and second
be shifted to accommodate structural requirements. Hollow metal
doors should be used for non-training doors for identification
purposes. During search and identification classes, the trainee
should be instructed to use only watertight doors.
a) Access to the first floor from the second floor
should be through a horizontal large hatch. These hatches are
to be located between floors instead of on the roof because the
roof location would require the roof to be 2438 mm wider. Also
the hatch will get hotter located between floors which is a plus
for training.
b) The heat shield for the Ellison door is a definite
requirement, however, the shield restricts access to Compartment
1 from the escape trunk. For trainee safety, the bilge fire
will be programmed to be off, or in the low fire position, in
that corner during escape trunk training so the trainees can
walk in that area of the fireplace.
3.13.2.4 Fireplaces. Exact dimensions of burn areas are given
in Table 3 incrementally by compartment.
