pilot. The 19F4 trainer should have a 91 kg mannequin strapped
in a seat 2438 mm above the deck which should be rescued using a
portable ladder.
c) Some of the larger ships use a P-16,
self-propelled fire truck, to fight deck fires. Because the
trainer deck should be above grade due to the propane fuel,
resulting size limitations prohibit the use of the P-16.
Another negative aspect of P-16 use with this structure is that
it would require automotive type maintenance which is not
normally associated with firefighting schools.
3.16.2.7 Miscellaneous. Ordnance mockups should weigh
approximately 45 kg and be positioned manually by the trainees.

3.16.3.1 Use Rate. The 19F4 structure (see Table 12) has
utilities designed to support three classes of 60 trainees each
week. The class should be divided into four teams of 15
trainees each with two team leaders and one center leader. Two
teams at a time should fight fires alternately at a rate of
three fires per hour. The structure should be used for half a
day each day of the week for two 2-day classes and one 1-day
accelerated class. Each class should receive 5 hours of fire
exposure time.
3.16.3.2
Firefighting Agents
a) Flush deck nozzles are used on the flight deck of
a ship as a countermeasure to prevent accumulation of
contaminants during a chemical biological radiation (CBR) attack
and with foam to aid in fighting fires. On the 19F4 structure,
use deck nozzles for demonstration purposes only and supply with
water only. Nozzles must be installed in the fireplace grating
by the device contractor. A 152 mm water line must terminate
near the edge of and below the trainer deck with a motorized
valve. The water line must have a manual shutoff valve and a
pressure regulator valve prior to the motor operated valve. The
water pressure for the flush deck nozzles should be the fire
main pressure. The tie-in point for the device contractor
should be the outlet of the motorized valve.
