g) Other than the firefighting water, potable water
for drinking and cool-down showers should be supplied to each
device structure. The drinking fountain should be a pipe which
shoots the water in an arch to a drain and the shower should be
an emergency shower. Eyewash showers are not required.
h) Emergency water is defined as
water delivered
under pressure, over 700 kPa during a power
outage. Emergency
water is not required for the 19F and 21C12
series trainers
because water could not extinguish the fire
in an emergency.
i) Due to previous problems of piping failure from
bursting under pressure, do not use PVC or other plastic
materials for firefighting water piping. Piping should be
suitably rated for 2100 kPa.
2.2.4.2
Water Storage. Sufficient water storage should be
provided to ensure that the water demand can be met under all
operating conditions without starving the pump suction. Water
storage should be available on the site or in the vicinity.
Water storage should be sufficient to supply the facility needs
such that once a class is started (including classroom time), it
can be finished. Design the water storage tank in accordance to
AWWA standards. Tank should include the following: level
gauge, automatic means for filling, vent, manways, OSHA approved
ladders, etc.
2.2.5
Wastewater. Effluent from the training structures
should be collected in an equalization tank, treated, and pumped
at a metered rate into the sanitary sewer system. The ultimate
disposal of the effluent should be through a biological
treatment process. If the public owned treatment works (POTW)
does not incorporate that degree of treatment, the fire facility
should biologically treat the wastewater prior to discharging it
(refer to Section 5).
2.2.6
Electrical Power. Provide sufficient electrical power
in underground conduit to each structure to meet the needs of
the building and device equipment, including the computer.
Demand quantities are listed herein. Provide spare capacity in
both power and control conduits. Separate conduits should be
