Fireplace compartments should have refractory lined
walls and ceilings. In addition, compartment walls should have
steel plate liners to protect walls from the water hose stream
and to maintain compartment temperature. The bilge fireplace
compartment ceiling should also have steel plate liner. The
electrical panel and trash can fireplaces should have grating
floors. The bilge fireplace should have a chained doorway,
floor, and a fireplace support as shown on Appendix A, Figure
Required compartment dimensions should be clear
dimensions from refractory wall coating to steel plate wall
liner. Fireplace compartments should be thermally isolated from
the facility structure to allow for thermal expansion.
Note: Facility to provide fireplace steel gratings.
NAWCTSD will supply drawings and cost estimate to the facility
architect during design phase.
18.104.22.168 Instructor's Station. The 19F5 and 19F5A structures
should include two 3658 mm by 3658 mm instructor's stations.
One for each set of fireplace compartments. The 19F5 and 19F5A
structures should be separated by an electrical room measuring
3658 mm by 7925 mm. All three rooms should be located on the
second floor along the side of the staging area and should have
a 305 mm high raised floor. Access to the instructor's stations
should be by stairway or through the electrical room. Each
instructor's station should have a 3048 mm by 762 mm window
overlooking the staging area. The lower edge of window should
be 610 mm off of the computer floor.
22.214.171.124 Egress Chamber. An emergency egress chamber should be
provided which should present the trainee with a loss of light
and a high temperature, smoky environment. The trainee should
enter and leave the chamber through smoke filled entryways.
These entryways should be designed to block light from entering
