Crash lockers should be the same as repair lockers.
Doors and Hatches. Various types of entryways defined
here are used throughout firefighting training structures.
Doors used for emergency exits should be adequately marked and
should have panic hardware.
Watertight Doors. Watertight doors should be provided
in accordance with NAVSHIPS Dwg. 805-1400066, galvanized steel
with three dogs unless indicated otherwise, see Appendix A,
Figure A-12. Refer to NAVSHIPS Dwg. 805-1400074 for details of
airtight doors. Airtight doors as shown on NAVSHIPS Dwg.
805-1400074 can be used in lieu of watertight doors since
submergence in water is not a requirement. Airtight doors are a
good simulation to watertight doors. No hasp assembly is
required. Three dogs are used instead of eight because the door
will warp when subjected to heat and many of the dogs would not
work. Since the door will have to be replaced periodically
because of warping, it is desired to keep the door as
inexpensive as possible. Quick-acting watertight doors should
be a watertight door provided with a single lever to operate the
three dogs at once. Refer to Appendix A, Figure A-7. Quick-
acting, airtight doors should be provided in accordance with
NAVSHIPS Dwg. 805-1400074.
Hollow Metal Doors. Hollow metal doors should be
standard exterior doors with standard door knobs. Panic
hardware should be used on doors labeled "Emergency Exit."
Typically, doors should be 900 mm wide except that doors to
instructors' stations, burner/electrical rooms, and electrical
equipment rooms should be 1200 mm minimum width doors to allow
for equipment access.
