126.96.36.199 Fireplace Compartment. The fireplace compartment
should meet the following criteria:
a) Bulkhead should be located to maintain a clearance
from the backwall of 228 mm plus or minus 12.7 mm. One wall
should simulate a curved bulkhead. There should be two 3000 mm
lengths of bulkhead, 3810 mm high with a curve radius of 4572 mm
supported by ribs. Bulkheads should be spaced 4572 mm apart.
Each bulkhead should have three support ribs spaced 900 mm
apart. Ribs should be T-shaped, 254 mm high with a 203 mm top
and constructed of 6.4 mm steel plate. Bulkheads and ribs
should be made of steel in accordance with ASTM A36, Structural
Steel. Wall ribs will be insulated by the device contractor to
give a submarine-like appearance. The wall on the opposite side
should be a vertical wall because it is hidden from the trainees
by a 2150 mm, steel partition. This partition should contain
two emergency air breathing (EAB) outlets located in 304
stainless steel housings which will shield the EAB outlets from
the fires. EAB outlet housings are designated as "EO" in
Appendix G. The emergency corridor is behind this partition.
The corridor is not part of the training compartment and
therefore does not have to retain a submarine-like appearance.
Provide a 102 mm high steel kickplate around the edge of the
training floor by mockups and fireplaces at the grating floor as
shown in Appendix G, Figure G-1. The kickplate should minimize
the trainee's feet from slipping into mockups and fireplaces.
Broom finish concrete floors located in fireplace compartments.
Provide two floor drains in the emergency corridor.
b) Short masonry walls opposite the partition should
support the SHS1 hose station and EAB cabinets. The main
walkway and emergency corridor floors should be concrete while
the 1200 mm wide walkways leading to fireplaces should be steel
plate. A grating equipment floor should be 310 mm below the
training floor which should be continuous under the mockup.
Mockups should be mounted on the grating equipment floor.
Mockups should be located within 76 mm of steel walkway to
preclude someone from getting their foot caught in the void.
between the mockups to prohibit a person from falling onto the
grating equipment floor.
