3.17.3.1 Use Rate. Utilities for the 19F5 and 19F5A structures
are designed to support five classes of 160 students each week.
A class should be divided into two groups (A, B) of 80 men.
Group A should spend the morning fighting fires in the six
fireplace locations while group B watches the demonstration,
e.g., wild hose, P-250 pump, portable extinguishers, etc., and
goes through the emergency egress chamber. In the afternoon the
two groups switch. A typical schedule should consist of five
classes per week, 800 trainees for 52 weeks or 40,000 students
per year. For class schedule and utilities requirements, see
Table 13.
3.17.3.2 Firefighting Agents. Firefighting water entering the
structure should come through a motorized valve. This valve
should be controlled from the DTC and act as an emergency
shutoff valve in case of an uncontrollable hose.
a) Six standpipes, two foam stations, and two foam
reels should be located in the center of the staging area. Only
the reels and agents should be used for training purposes. The
foam proportioning equipment which feeds the reels should be
operated by instructors. Therefore, it can be standard
commercial. The design should allow for any two reels to
operate simultaneously, one for each bilge compartment.
b)
Provide a 9 kg portable PKP extinguisher outside
of each bilge compartment. Provide a 6.81 kg portable CO2
extinguisher outside of each electrical panel compartment.
Additional extinguishers which should be used as replacements
should be purchased as collateral equipment.
c) Hose stations in the 19F5 structure do not require
the instructor operated hose station disabling valve.
