FIRE PROTECTION
As Outlined by Louisiana
Fire Prevention Bureau

SYSTEM Either of the followir
z systems will be accepted as standart
9 gravity system from reservoir, dire,
pressure from pumps, intermittal
2 pumping to stand pipe or reserve
z with special fire pressure.
? FIRE STREAMS Streams necessar
3 for proper protection of a town {
: 1000 population is seven.
: A fire stream is considered as dc
: lIvering 400, 900 gallons per diem.
: PREssURE-A fire pressure of Z
pounds per square inch at thydrant cut
: let, with, the full number of fir
streams in operation, must be fur
nished.
CAPACITY The system must be o
suthcient capacity to furnish the full
number of fire streams required, il
addition to the average daily consump
tion.
WATER SUPFLY-A water suppl,
capable of delivering so per cent. ir
excess of the combined average dali,
consumption for domestic purpose!
and quantity necessary to furnish the
required number of fire streams to be
Immediately available, either from
streams in near vicinity or from ar;
tesian wells.
RESERVoIR-W When the system is by
gravity from an elevated reservoir,
the elevation to be sufficient to insure
the necessary pressure, as stated
above, and the capacity to be sufi-
cient for the storage of at least 10
days supply for the average daily con-
sumption for domestic purposes, to-
Igether with an abundant reserve for
| fire purposes. To elevate the water
| to the reservoir, pumping station to
be established at the supply. The
station to be equipped as called for
under caption Pumping Stations"
and the main from station to reser-
voir to have carrying capacity of 10
per cent in excess of the total daily
domestic and fire consumption re-
quired. Duplicate mains to be run
from reservoir to city system.
FILTRATION PLANTS. - When it is
necessary to filter water for domestic
purposes, the pumps for supplying the
muddy water must be independent of
the pumps supplying the town and
must be IN duplicate, same as other
pumping machinery. The filtration
plant must have capacity of at least
10 per cent in excess of the total daily
domestic and fire consumption, and
clear water from same must pass to a
clear water basin of at least 200, 600
gallons capacity.
STAND PIPE When used in connec-
tion with a waterworks system, stand
pipe to be at least 20 feet in diameter
and 125 feet high, having a capacity
of about 294, 900 gallons. Stand pipe
to be of steel, thoroughly riveted and
we'll braced, and foundation for same
to be carefully laid and all necessary
precautions taken against careening or
disruption.
Stand pipe to be connected to system
by a single pipe line, in which an
automatic cutoff valve must be placed.
This valve to be of such design that it
can be opened or closed by engineer
at pumping station.
Pumps must work against pressure
equal to the full head of the stand |
pipe and must be run at a speed suf-
ticient to keep stand pipe full at all
times. A guage to be placed in pump
ing station to indicate height of water
in stand pipe.
PUMPING STATIoN-To be ,unex-
posed, built of brick; concrete or brick |
floors, open joisted ceilings, slate,
metal or composition roofs. Station |
to be used exclusively for water works
pumping station, and must not be &C.
cupied by electric light plant or other |
special hazard, and should be divided |
by standard parapetted brick wall into |
boiler house and pump house. Open
ings in brick wall, if any, to be pro-
tected by standard fire doors on each |
side of wall.
In boiler house section no woodwork |
to be within feet of boilers or fume |
and if metal stack passes directly |
through roof same to have at least II |
inches clearance from all woodwork |
where passing through roof.
Pumping station to be protected by |
an adequate, number of outside hy- |
drants, each having $50 feet 2 25-S-inch |
National Standard cotton rubber !
lined fire hose and 1-8 inch smooth |
nozzle play pipe attached. Pumping |
station must have telephone connec-
tion and fire alarm connection when
fire alarm telegraph system obtains
in the city.
BOILERS Sufficient boilers in units
OF 100 horse power each to be installed
to run entire equipment of Pumping
Station at one time. Owing to require
ments for duplicating pumping ma
chinery, it will be necessary to run
one-half the boilers at time.
Duplicate boiler feed pumps for
each battery of boilers will be required. |
FUEL When coal is used for fuel,
at least two weeks supply shall be
kept on hand at all times.
When fuel oil is used, the oil storage
tanks must be installed in full con-
formity with the rules and require
ments of the National Board OF Fire
Underwriters. Duplicate oil feed |
pumps Ito burners) will be required |
for each battery Of boilers.
PUMPING MACHINERY. Two dupi- |
cate sets of pumping machinery to be |
installed for all purposes, whether it |
be low service pumps for raising
water from supply to filtration plant |
or high service or high duty pumps |
for pumping water from supply or
clear water basin to gravity reservoir,
stand pipe or direct to city mains.
All pumps must be properly provided |
with foot valves and strainers on sue
ton pipes and with gate and check
valves on discharge pipe. All pumps |
to be of the Duplex pattern.
MAINS. AL underground mains to
be OF cast iron, and conform to the |
New England water works standard. |
No mains of less than 6 inches in |
diameter will be accepted for fire pur- !
poses.
In direct pressure and intermittant !
pumping to stand pipe, duplicate sup
ply mains will be required from pump |
ing station to city distribution mains. |
These two supply mains to be proper
ly provided with gate valves for cut
