b) The courses taught on the 19F4 and 19F4A trainers
require exposure to the wild hose facility. The wild hose may
be taught on the ground adjacent to the 19F4 structure. Only
one wild hose facility should be required at a firefighting
school.
c) The propane supply should terminate at the side of
the structure as shown in Appendix E, Figure E-1.
3.16.3.6
Foam Proportioning
a) The foam for foam decks should be proportioned in
the foam room with less than 3 percent AFFF solution being piped
to each foam standpipe. Concentrate should be pumped to the
mixing tank in the foam room. An industrial type proportioner
should take 100 percent solution from the mixing tank and
produce less than 3 percent solution. A balanced pressure
system should be used as shown on Figure E-6 of Appendix E.
b) The high capacity fog foam generator (HCFF) or
FP-1,000 are used aboard ship to proportion firefighting foam.
There are aspects of this equipment which are not conducive to
firefighting training. The HCFF or FP-1,000 should not be
incorporated in the 19F4 or 19F4A for training purposes. This
equipment type training should be accomplished aboard ship.

Electrical
3.16.4.1
Power
a) Power required for the device is 85 kVA.
Provide
120/208 V, three-phase service.
b) Provide eight 50 mm spare conduits from the
two-story instructor's station building to the 19F4 training
structure. These conduits should be used only by the device
contractor for both power and control. Power and control wiring
should be run in separate conduits.
3.16.4.2 Lighting. The 19F4 structure should be lighted for
nighttime operation. However, provide security lighting. The
crawl space should be fully lighted with switches by doors.
