Light material construction methods do not offer.

inherent protection against fire unlike the _____

on the other hand, considers the building density in the locality and the flammability of the Structures and its contents.

is one alternate to replace the elevated water tank. It is a reinforced concrete structure constructed on one side of the building, provided with a small vent rising above the ground.

The______ is a traditional design of storing water in an elevated reservoir for the following purposes:

1. To supply a constant pressure of water in the distribution lines.

2. To store sufficient water to balance the supply from the demand.

3. To prevent excessive starting and stopping of the pump.

4. To provide dependable supply for fire reserve.

The ______ Tank has also the following disadvantages:

1. Unsightly appearance

2. High cost of construction

3. Requires massive structure and foundation for ‘its

tremendous weight.

the ____ is one alternate to

replace the elevated water tank. It is a reinforced concrete

structure constructed on one side of the building, provided

with a small vent rising above the ground.

-it completely eliminates the problem of unsightly appearance and weight.

the _____ provides a continuous flow of water from the deep well through the domestic and

fire reservoir. The continuous flow of water prevents it from becoming stagnant and rancid. The fire reservoir has the priority over the domestic reservoir by means of a simple weir. Even if the domestic reservoir is totally empty, the fire reservoir would remain full of water.

small 20 gallons per minute_____ will supply the necessary pressure for the sprinkler system, and consequently, a signal from the sprinkler system will start the 750 gpm main pump. If this pump becomes inadequate

for the demand, a diesel engine driven pump of equal capacity will automatically takes over.

The ____which control the operations of the pumps are:

1. The Bubble Control Units in each of the two reservoirs.

2. The Dual Control Unit that regulates ie supply

for the pressure tank.

The Dual Control Unit that regulates is supply

for the ____.

A____ is used to store air under pressure that will balance

out-surge from the two domestic pumps and reduce the frequently starting, and stopping of the motor.

It is an improvement of the closed system,

where several pumps are sequenced automatically to supply an even pressure.

It has the advantage of using only two pumps when necessary.

One disadvantage of this system is the difficulty in

maintaining the ratio of 60% air to 40% water. Water from

deep well to the tank becomes air bound as water stored

therein gives up its absorbed air.

The _____ is a pipe installed in buildings not as

part of the water supply or disposal system, but primarily,

for use as water conveyance in case of fire.

The ____ is always located near the stairs for use

by firemen in case of fire. It is incased in glass cabinets

with the following label: Break Glass in Case of Fire.

The Fire Hose is always located near the stairs for use

by firemen in case of fire.

It is incased in glass cabinets

with the following label: ____

Upon arrival of the firemen, the standpipe ____ is immediately connected to the street fire hydrant, or to any other water source e by their fire

hose.

The length of the firemen hose is limited to a certain height, but because of the ______, the upper most floor of a tall building, could be

reached by the fire fighters.

The automatic sprinkler system consists of _____ placed near the ceiling of industrial and commercial buildings, warehouses, stores, theaters and

other structures where fire hazard require their use.

these pipes are provided with outlet and sprinkler

heads that open automatically at temperatures of _____ and emit a series of fine water sprays.

the ____ refer to the piping installations wherein

both the mains and the distribution pipes are constantly

filled with water.

The ____refers to the piping installations where

there is no water standing in the distribution pipe, except

during the occurrence of fire. This is generally confined to

unheated buildings.

When a gravity tank is used with sprinkler system, it

must have enough water reserve for this purpose and

enough water to operate at least____. This time is sufficient to give the fire department a chance to arrive and take over.

the ______ is one of the common types of fire protection installed in buildings. This kind of standpipe is connected to the water supply and distribution system. The disadvantage of this installation is when there is inadequate water supply for fire fighting.

A connection between the domestic water system and the fire distribution main must be provided with ________.

These devices will prevent contaminated water in entering into the water distribution system.

The _____ will serve as safeguard that may be closed by the firemen in their routine operation.
