FIRE PROTECTION MANUAL
PREFACE
The First Edition of this Manual was issued by the Calcutta Fire Insurance
Association in 1906 and was brought up-to-date and re-issued in 1930. The
third, fourth and fifth Editions were published jointly by the Insurance
Associations of India and Pakistan in 1948, 1950 and 1953 respectively to
provide for the needs of the whole of the areas controlled by these
Associations. The subsequent sixth, seventh and eighth Editions were
published by the Fire Sectional Committees of Calcutta, Bombay, Delhi and
Madras Regional Councils of the Insurance Associations of India. In the
ninth Edition published in 1982, amendments and additions were effected to
bring the provisions in line with current thinking on fire protection
techniques and to encourage installation of fixed fire extinguishing
appliances/alarm systems in relatively low hazard risks on the one hand and
tighten requirements for design of systems suitable for high hazard risks
such as Petroleum Refineries, Petrochemical and Fertiliser Plants on the
other hand, which, world-wide experience has indicated, need copious
quantities of water and other extinguishing media. In this tenth Edition an
effort has been made to further update and streamline the regulations.
The Manual should prove of value to factory owners and their technical
personnel when dealing with matters relating to fire extinguishing
appliances and also constitute a handy book of reference to Insurance
officials.
The maintenance of fire extinguishing appliances in an efficient state and
familiarisation with all details of operations is essential if the maximum
benefit is to be derived in the emergency of an outbreak of a fire.
The Manual incorporates long experience of fire protection engineering
both in India and elsewhere in the world. Compliance of the rules will not
only obtain appropriate discount in the fire insurance premium but will also
instil feeling of security that the presence of an efficient fire-fighting
equipment should engender. Direct loss from fire and the resultant wastage
is always serious but the indirect loss and the resultant dislocation of
business is often much more serious.
The Regional Offices of Tariff Adv. Committee maintain an inspection staff
of qualified engineers, specialists in fire protection and prevention
engineering and practice in all its aspects. The services of this staff are
available to make recommendations and carry out inspections in keeping
with the nature of work. (All references to Committee or staff thereof in this
preface and in the body of the Manual apply to the Committee controlling
the territory within which the risk is situated).
The Manual initially deals with portable appliances and small bore hose
reels, which are considered as first-aid appliances. The regulations
regarding trailer pumps are covered next. The last part is devoted to fixed
external protection in the form of a hydrant system which is considered the
backbone of the entire fire-fighting operations as it fights fires of serious
proportions in all classes of risks and continues to do so even in the event of
a collapse of the buildings/structures protected. High-rise buildings which
have become a common feature of modern society present inherent fire
hazard as fire brigades are often helpless in the face of fires in such
structures and are unable to save human lives and fight fires effectively
with traditional methods. A separate section has, therefore, been devoted for
prescribing the specialised type of protection required by these structures.
In case it is desired to install any appliances, which are not covered by this
manual, assistance and advice may be obtained from the inspection staff
maintained by the Regional Offices.
Wherever reference to any Indian Standard appears in this Manual, it
should be taken as a reference to its latest version.

will be sanctioned by the Committee from the date of the
completed application, (in accordance with 2.5 and 2.6
above) subject to the appliances being found in order on
inspection by the Committee’s Inspectorate. In the event of
the installation being found incomplete or defective, the
discount will be with held (or withdrawn if already
notified) until the detects have been rectified to the
satisfaction of the Committee.
2.10 No allowance shall be made for Fire Extinguishing
Appliances until notified by the Committee either by letter
or circular, and then, with effect only from the date
specified in such notification.
2.11 Discounts sanctioned solely on account of installation of

3.
COMMITTEE'S INSPECTION STAFF:
3.1 The Committee undertakes, as far as possible, the periodical
inspection of all premises in which fire extinguishing appliances,
entitling the risk to special discounts or ratings for such appliances,
are installed.
For this purpose, the Committee’s Inspection Engineers shall have
the right of access to the premises of the Insured at any time with
or without giving any prior notice.
3.2 The Primary duty of the Inspectors is to report to the Committee on
the condition and efficiency of the appliances installed as well as
to ensure the regulations are being observed. They will, however,
give help and advice in the maintenance of the appliances and on
matters pertaining to fire protection and prevention.
3.3 The attention of the Inspecting Engineers shall be drawn, during
their visits, to any changes effected since the previous inspection
or to any contemplated extensions and alterations to the existing
services. This procedure does not, however, dispense with the
necessity of advising the Insurance Company or Companies
interested on the risk of any changes, which affect the plan of the
risk or the details of the appliances, recorded with Committee.

INTERNAL APPLIANCES -
4.
Internal appliances generally consist of hand appliances (first aid
appliances) and hose reels.
4.1 HAND APPLIANCES 4.1.1
GENERAL –
4.1.1.1
Hand
appliances
extinguishers.
comprise
buckets
and
4.1.1.2 ALL APPLIANCES INCLUDING EXTINGUISHER
REFILLS AND FOAM COMPOUND SHALL BE IN
CAPACITIES INDICATED IN THE RELEVANT INDIAN
STANDARDS SPECIFICATION AND SHALL BEAR ISI
CERTIFICATION MARK.
(Accessories including
extinguisher refills shall also be ISI marked) BUCKETS
SHALL BE OF ROUND BOTTOM TYPE.
4.1.1.3 The usefulness of these appliances is limited, as it is entirely
dependent upon the presence of persons having knowledge to
operate them. Everything depends, however, on the speed
with which they are brought into use as they are essentially
‘First-Aid’ equipment, only meant for attacking small fires in
their incipient stages and are not intended to deal with large
outbreaks of fires.
4.1.1.4 Since a variety of shapes and/or methods of operation of fire
extinguishers can at times lead to confusion and as failure to
operate the extinguishers properly in the first instance results
in failure to quench the fire, it is recommended that
extinguishers installed in any one building or single
occupancy be similar in shape and appearance and have the
same method of operation as far as possible.
4.1.1.5 It is recommended that an indicator board showing the
number of buckets and extinguishers installed in each
department be provided over or near the main entrance to the
department. This will enable the person in charge of the
appliances to ascertain at a glance if any appliances are
missing.
4.1.1.6 It is advisable to provide conspicuous location indicators of a
suitable type for all extinguishers, particularly those located in
large compartments.
4.1.2
SELECTION OF HAND APPLIANCES:
4.1.2.1 Various types of hand appliances are available but all are not
equally effective on all kinds of fires. For this reason, the
nature of contents of a building, the processes carried out
therein and the types of fires, which may occur, shall be taken
into consideration while selecting fire appliances.
4.1.2.2 The different types of fires and appliances suitable for use on
them are as under –
Class
Combustibles
Hand Appliances
A
Fires
in
Ordinary
combustibles
(Wood,
Vegetable fibres, rubber,
plastics, Paper and the
likes).
Gas expelled Water
and Antifreeze type

and liquefied gases.
Chemical
Extinguishers of Carbon di
oxide and Dry Powder
type.
D
Fires
in
reactive
chemicals, Active metals
and the likes.
Special type of Dry
Powder,
Extinguishers and sand
buckets
N.B - WHERE THE ENERGISED ELECTRICAL
EQUIPMENTS ARE INVOLVED IN A FIRE, THE NONCONDUCTIVITY OF THE EXTINGUISING MEDIA IS OF
UTMOST IMPORTANCE AND ONLY EXTINGUISHERS
EXPELLING DRY POWDER OR CARBON-DI-OXIDE
(WITHOUT METAL HORN) SHOULD BE USED. ONCE
THE ELECTRICAL EQUIPMENT IS DE-ENERGISED
EXTINGUISHERS SUITABLE FOR CLASS A, B AND C,
MAY BE USED SAFELY.
4.1.3
REQUIREMENTS OF HAND APPLIANCES -
4.1.3.1 Procedure The minimum number of fire extinguishers needed to protect a property

Selection of Sites for the Installation of Hand Appliances:
4.1.4.1 When selecting sites for hand appliances due consideration
shall be given to the nature of the risk to be covered.
Appliances shall be placed in conspicuous position and shall
be readily accessible for immediate use in all parts of the
occupancy. It should always be borne in mind while selecting
sites that hand appliances are intended only for use on
incipient fires and their value may be negligible if the fire is
not extinguished or brought under control in the early stages.
4.1.4.2 Generally, hand appliances shall be placed as near as possible
to exits or staircase landings. Wherever possible, advantage
shall be taken of normal routes of escape by placing
appliances in positions where they can readily be seen by
persons following the natural impulse to get out of danger. It
is not advisable to place appliances at the end of rooms remote
from exits unless they are necessary to cover a particular
hazard there.
4.1.4.3 Buckets shall be placed at convenient and easily accessible
locations either on hangers or on stands. In the case of textile
mills, it is strongly advised that a bucket be slung at the end of
each spinning and roving frame.
4.1.5
Maintenance of Hand Appliances:
4.1.5.1 General
4.1.5.1.1 It is important that hand appliances are always kept in
their proper positions and if temporarily removed for
repairs, are immediately replaced. In order to ensure
this, all concerns shall arrange to provide at least one
man, preferably a pump man, whose duty is to see that
the fire buckets are filled with water and the
extinguishers are in efficient working order and that all
appliances are in their correct positions.
4.1.5.1.2 It is recommended that in case the paint of any hand
appliance gets chipped off or gets faded; it shall be
repainted to prevent it from rust and corrosion.
4.1.5.2 Buckets:
4.1.5.2.1 Fire buckets shall not be used for any purpose other
than that for which they are intended, and shall always
be kept full of water/sand.

rules of local bodies, the water in fire buckets shall be
refilled every week and treated with sapon creosote or
phenyl in suitable quantities to just discolour the water.
4.1.5.2.3 All buckets shall be refilled with clean water or sand, as
the case may be, immediately after use.
4.1.5.2.4 Spare buckets to the extent of 10 % of the total number
installed on the premises, subject to a maximum of 50,
shall always be kept in store.
4.1.5.3 Extinguishers:
4.1.5.3.1 Spare charges to the extent of 10 % of the total number
of extinguishers installed, with a minimum of two shall
always be kept in stock for each type of extinguisher
and be readily available.
4.1.5.3.2 Once a week, the extinguisher shall be checked to
ensure that all movable parts are working properly, that
the plunger is in fully extended position, that the nozzle
is not obstructed in any way and that there is no leakage
of the extinguishing medium from the glands and
nozzles.
The extinguishers shall be cleaned
superficially and the brass parts polished. The nozzle
outlet and vent holes in the threaded portion of the cap
shall be checked for clogging.
4.1.5.3.3 Once a month, extinguishers of the Carbon Dioxide
type shall be weighed. If the weight recorded for any
extinguisher is less than 90 % of the weight of the fully
charged extinguisher as marked on the body, the
extinguisher shall be sent for recharging.
4.1.5.3.4 Half the total number of water type of extinguishers and
one-fifth of the total number of Dry Powder
Extinguishers installed in the premises shall be
subjected
to
an
operation
test
annually.
Advantage shall be taken of this test to impart training
in the use of extinguishers, to the staff employed on the
premises where the extinguishers are located.
N.B. Extinguishers, which have been used in a fire
during a period of six months preceding the tests, need
not be taken for testing.
4.1.5.3.5 Extinguishers installed in the premises shall be
subjected to a hydraulic test as specified in IS: 2190 and
at such intervals as laid down therein. Extinguishers
found leaking or distorted shall be rejected. Under no
circumstances shall such extinguishers be welded and
reused.
N.B. The hydraulic test shall be certified by the
manufacturer(s) of the appliance(s) or the factory Chief
Engineer or the Factory Fire OR SAFETY OFFICER or
the service contractors.
4.1.5.3.6 A record of the operation and hydraulic tests shall be
maintained, which shall be open to examination by the
Committee’s inspection staff.
4.1.5.3.7 The operating instructions of the extinguishers shall not
be defaced or obliterated. In case the operating
instructions are obliterated or have become illegible due
to passage of time, fresh transfers of the same shall be
obtained from the manufacturers of the appliances and
affixed to the extinguishers.
4.2 Small Bore Hose Reels:
(This sort of protection is not deemed suitable for
buildings/compartments containing electrical apparatus only or in
respect of buildings/ compartments in which flammable liquids are
stored and/or used)
4.2.1
HOSE REELS SHALL NORMALLY BE CONNECTED TO
THE GENERAL WATER SUPPLY PIPELINES OF THE
PLANT/PREMISES.
4.2.2
The number and distribution of hose reels shall be such that
the whole of each floor is protected and that no part of the
floor is more than 6 m. distant from a hose nozzle when the
hose is fully extended.
4.2.3
The hose reel shall be such as will enable not less than 22.5
litres of water to be discharged per minute through a nozzle of
not more than 6.35 mm. internal diameter.
4.2.4
Hose shall be of reinforced rubber not less than 19 mm. and
not more than 32 mm. internal diameter.
4.2.5
Hose lengths shall not exceed 36.50 m.

MECHANICALLY DRIVEN FIRE ENGINES AND TRAILER PUMPS
5.1 Application:
5.1.1 This method of protection will be accepted on its own merits for
the protection of blocks/facilities (other than open storage) in
light and ordinary hazard occupancies. Even in these
occupancies buildings, which have the highest point of the roof
not exceeding 20 meters, shall only be deemed to be protected.
5.1.2 For effective application, mobile engines and/or trailer pumps
shall be sited at convenient locations from where they can be
speedily moved to any portion of the compound in the event of a
fire and for this purpose adequate vehicular arrangements shall
be available for towing trailer pumps.

HYDRANT PROTECTION OF HIGH RISE BUILDINGS (NONINDUSTRIAL)
6.1 Introduction 6.1.1 A building, the highest floor of which is more than 22 M above
the surrounding pavement level, shall be considered as a highrise building.
6.1.2 The rules are applicable to all types of buildings with nonindustrial occupancies such as Residential Hotels, Mercantile/
Business/Office buildings, apartments etc.
6.1.3 In case of Buildings situated in slopping terrain, reference shall
be made to the Committee in advance with full particulars.
6.2 Hydrant Protection (at ground or yard levels) 6.2.1 The ground level protection with hydrants on terminal mains will
be acceptable, provided the plinth area of the building to be
protected is less than 750 m2. The location of the hydrants at
ground level as well as the layout of the hydrants system shall,
otherwise, comply with various provisions under Section 7 of
this manual.
6.2.2 In case of buildings having a plinth area in excess of 750 m 2, the
location of the hydrants at ground level as well as the layout of
the hydrant system shall be governed by the appropriate
provisions under Section 7.6 of this manual. The Committee
reserves its right of insisting on water monitors in place of few
hydrants if deemed necessary.
6.2.3 Orifice plates of suitable design shall be provided in the landing
valves, where necessary, to limit the operating pressures within 7
kg/cm2.
6.2.4 Except where impracticable, all hydrant outlets shall be situated
1.0 m above ground level.
6.3 Hydrant Protection - at various upper/lower (basement) levels
6.3.1 Access staircase
6.3.1.1 Design for a new building shall include provisions for adequate
access staircases and lifts to provide efficient means of escape
and facilities for fire fighting.
6.3.1.2 One lobby approach staircase along with fire lift shall be
provided for every 1,000 m2 of floor area of each storey/level
(including basements). Normally a minimum of two such
staircases shall be required but in case the area of each storey is
less than 500 m2, one staircase is acceptable.
6.3.1.3 The lobby approach staircase shall be of non-combustible
construction. At least 50 % of total numbers of staircases
required (with a minimum of one) shall be so located that one
of their enclosing walls be an external wall of the building.
6.3.1.4 Doors at the entrances of both the lobby approach access
staircases and fire lifts shall be provided with self-closing,
smoke-tight doors having one-hour fire resistance. This
arrangement will enable escape and fire fighting to be effected
more efficiently.
NOTE: If the staircases and the fire lifts are located in the core
of the building, a positive pressure of 50 Pa or 20 Pa in excess
of pressure in the lobby whichever is higher, shall be
maintained within the former as an alternative to the above
provision.
6.3.1.5 The fire lifts shall be controlled by the fire brigade recall from
the concourse level and shall not respond to other calls after the
fire brigade key has been activated. The cable supplying power
to the lift motor shall pass through routes of negligible fire risk.
6.3.2 Wet Risers 6.3.2.1 Wet riser(s) is/are a pipe or a number of pipes, permanently
charged with water under pressure, rising through the full
height of the building.
6.3.2.2 The wet risers shall be located within the lobby approach
staircases.
6.3.2.3 The diameter of the riser pipes shall not be less than 150 mm
anywhere. One or two landing valves shall be connected to the
riser pipe at each storey/level. In case of excessive pressures in
hydrant outlets at lower levels, orifice plates of suitable design
shall be provided in the landing valves, where necessary, to
limit the operating pressure to 7 kg/cm2.
6.4 Hose Pipes and Nozzles
6.4.1 Sufficient length of hose, subject to a minimum of two lengths of
15 M each with couplings attached, shall be provided for use in
case of each hydrant point on risers. In addition, one nozzle of
20 mm size fitted to a branch pipe shall also be provided. To
avoid water damage, it is advisable to have reinforced rubberlined hoses for use with internal hydrants. (IS-636)
6.4.2 The number of hose pipes provided near external yard hydrants
shall be such that no part of the floor is more than 15 M from a
hose nozzle when the hose is fully extended and connected to
hydrant landing valve.
6.4.3 Hoses, nozzles and branch pipes shall be kept adjacent to the
hydrant outlet, in wall boxes or recesses in the walls specially
designed to blend architecturally with the buildings, if so desired.
All other requirements relating to the appurtenances shall be as
per the provisions under Section 7.7 of this Manual.
6.5 Pumping Arrangements
6.5.1 Each wet hydrant installation shall be supplied with water by an
auto-start pumping set. A stand-by pump set of identical
pumping capacity having a different prime mover shall also be
provided.
6.5.2 Pumps shall have capacities of 38 Litres. per seconds (137 m3
per hour) or 47 Litres. per second (171 m3 per hour) and the head
generated at the rated discharge shall be such that a minimum
pressure of 3.5 Kg/cm2 will be available at the highest landing
valve in the premises.
6.5.3 The suction, delivery and priming arrangements for the pump
shall comply with provision under Section 7.4.1 of this Manual.
6.5.4 Jockey pump(s) shall be installed in addition to the main pump
set(s). The pressure setting for the pump(s) shall be such that it
cuts in approximately at 0.35 Kg/cm2 below the normal system
pressure and cut out at normal system pressure. The main fire
pump(s) shall be arranged to cut in approximately at 1 Kg/cm 2
below the normal system pressure and shall be capable only of
manual shut down at churn pressure.
6.5.5 The power supply to the fire pump(s) shall be independent of all
other supplies within the premises. In other words even when
the power supply to the entire premises is switched off, the
supply to the fire pump(s) and other essential equipment shall
remain uninterrupted.
6.5.6 Pump room shall be normally located detached in the compound
of the building and shall preferably be 6 m away from the
building. Where it is not feasible the pump room can be located
inside the building provided it is segregated from the remainder
of the building in accordance with Committee’s regulations and
access to the pump room from the out side of the building shall
be either direct or through a passage which has no openings other
than to the pump room.
6.5.7 The pumping installation for the high rise installations shall
conform to anyone of the following methods to avoid
undesirably high pressures in the riser mains a)
Two pumps, one having a low head connected to the riser
feeding the lower storeys and the other having a higher head
connected to the risers feeding the upper storeys, shall be
installed.
b) A multistage multi-outlet pump shall be installed, separate
outlets being connected to the riser feeding the lower storeys
and those feeding the upper floors. (See figure 1 and 2)
N.B. - For buildings over 60 M in height, hydrant system may
either be designed as above or may be divided into pressure
zones. For each zone the water supply for the fire protection
would be designed to have pressure within the normal operating
ranges and zones of eight to ten storeys would be adequate with a
check valve in each zone to prevent the transmission of pressure
to the zone below (each zone shall have a height of 20 m to 25 m)
In each zone of fire protection piping, there shall be a gravity or
pressure tank supply. This shall be supplemented by a fire pump
to provide required flow in the zone. The fire pump shall not be
used to fill gravity or pressure tank.
This should be filled from domestic water lines. In this
arrangement, the pump in the lowest zone takes suction from
suction tank located at ground floor whereas pumps in other
zones take suction from the gravity/pressure tanks in the
respective zone (See. Fig. 3)
N.B.1: - In addition to the above system, a gravity tank of 25,000
litres capacity shall be provided on the top of the building and it
shall be connected to the pump delivery through a non-return
valve.
N.B.2 - The pump controls can be located with the pump in each
zone. It can also be provided at the ground floor depending upon
the suitability and practicability of the particular building in
question.
6.6 Water Source 6.6.1 Effective capacity of fire fighting tank (See rule No. 7.3) shall
not be less than 2 hrs. aggregate pumping capacity for buildings
less than 60 m in height. The tank capacity shall, however, be
increased to 3 hrs. pumping capacity for buildings having height
60 m and above. The tanks shall be constructed in two
independent but interconnected compartments as per rule 7.3 of
this Manual.
The fire tank must be in two compartments with a baffle wall in
between not going right down to the base of the tank. This
arrangement will ensure proper circulation of the firewater and
prevent stagnation. (See figure below).
6.6.2 The storage tank shall be provided with a 150 mm fire brigade
pumping connection to discharge at least 2,275 Litres per minute
into the tank. This connection shall not be taken directly into the
side of the storage tank, but arranged to discharge not less than
150 mm above the overflow level of the tank. The connection
shall be fitted with stop valve in a position approved by the
committee in advance. An overflow connection discharging to a
visible drain point shall be provided from the storage tank.
6.6.3 The fire brigade connection shall be fitted with four numbers of
63 mm instantaneous inlets in a glass fronted wall box at a
suitable position at street level, so located as to make the inlets
accessible from outside of the building. The size of the wall box
shall be adequate to allow hose to be connected to the inlets,
even if the door cannot be opened and the glass has to be broken.
Each box shall have fall of 25 mm towards the front at its base
and shall be glazed with wired glass with "FIRE BRIGADE
INLET" painted on the inner face of the glass in 50 mm size
block letters.
6.6.4 In addition to the emergency fire brigade connection to the
storage tank, a 150 mm connection shall be taken from the four
63 mm instantaneous inlets direct to each hydrant riser so that
the fire brigade may pump to the hydrants in the event of hydrant
pumps being out of the commission. The connection direct to
each riser shall be fitted with a sluice and reflux valve each.
6.7 Fire Fighting Staff
6.7.1 A fire fighting squad consisting of security and maintenance
personnel under the command of a trained fire chief, conversant
with the fire control system of the premises, shall be available.
Further, the public fire brigade shall also be acquainted with
what is being installed in the premises and how the protection
systems operate. For this purpose, details of the arrangements
for fire fighting systems and the layout plan incorporating the
position of the existing fire protection system shall be forwarded
to the local fire brigade for their information and necessary
action.
6.7.2 As the efficiency of the wet riser system depends on the manner
and speed at which they are brought into use, a squad consisting
of trained personnel and fire pimp man shall be maintained on
the premises round the clock. The number of personnel for the
squad shall necessarily depend upon the size of the building but
in no case shall be less than four trained persons (excluding
officer in charge on duty and pump man) be available at anytime
during the day or night.
6.7.3 A public address system shall be provided on each floor
including the control room in order to enable security and fire
fighting staff to give evacuation instructions to the occupants in
case of fire. Evacuation drills shall be arranged periodically.
6.7.4 A metal strip of 25 mm x 3 mm section shall be provided in the
staircase enclosure running throughout the height of the building
to facilitate transmission and reception of fire messages through
walkie-talkie sets used by brigade personnel. The strip shall be
electrically insulated from the ground.
6.7.5 A plan of the risk giving floor-wise details of all fire
extinguishing appliances and water supplied shall be displayed in
the pump house as well as in the room of the security/fire officer
who is in charge of the appliances.
**************
7.
HYDRANT SERVICE Installation of Hand Appliances as per the Committee’s Regulations is
a prerequisite for any occupancy, other than storage occupancy, to be
entitled to allowance for this system.
7.1 GENERAL 7.1.0 The following Regulations are not applicable to High-Rise
Buildings, the highest floor of which is more than 22 m above
the surrounding ground level or to Cotton Gin and Press
Factories, for which reference may be made to Sections 6 and 8
respectively.
7.1.1 A well designed and well laid hydrant service is the backbone of
the entire fire fighting equipment as it fights fires of serious
proportions in all classes of risks and continues to be in full
operation even if part(s) of affected buildings and/or structures
have collapsed, and also keeps cool all adjoining properties,
thereby minimising the exposure hazards.
7.1.2 The advantages of providing for possible future extensions in any
scheme of hydrant protection is often overlooked. A
comparatively small extension with its attendant friction losses
may overload a main so seriously as to necessitate replacement
by one of larger size and the small additional initial cost of mains
of somewhat larger capacity than immediate requirements may
call for, often leads to ultimate economy.
7.1.3 All components of the hydrant system shall be of a type and
make approved by the Tariff Advisory Committee.
7.1.4 The standards laid down in this Manual represent the
accumulated experience of many years but even when a hydrant
service is designed and laid in accordance with these standards,
its efficiency in fire fighting will ultimately depend upon the
rapidity with which it is brought into action and the ability with
which its effort is directed.
7.1.5 The maintenance of an installation is equally vital and the
importance of organised wet drills at regular intervals, which
ensure that each man carries out his allotted duties in the shortest
possible time cannot be too strongly emphasised. (Please see
rule 7.10 in this connection).
7.2 CLASSIFICATIONS OF OCCUPANCIES 7.2.0 As the water supply, pumping capacity and other features of the
hydrant system depend not only on the size of the risk but also on
its fire growth and spread potentialities, the risks are to be
categorised under the following classes for the purpose of
hydrant system design:

7.3 WATER SUPPLY 7.3.1 Water for the hydrant services shall be stored in an easily
accessible surface/underground lined reservoir or above ground
tanks of steel concrete or masonry. The effective capacity of the
reservoir above the low water level (defined hereunder), or above
the top of the pump casing (in case of flooded suction) if the
same is higher than the low water level, for the various classes of
occupancies and size of hydrant installations shall be as indicated
in the table 1.
NOTES –
1.
The low water level is a point atleast three times the
diameter of the suction pipe above the draw-off point. (See
figs.4, 5 and 6)
2.
Large natural reservoirs with water capacity exceeding 10
times the aggregate water requirements of all Fire Pumps
therefrorm may be left un-lined.
7.3.2 Reservoirs of and over 2,25,000 litres capacity shall be in two
interconnected equal compartments to facilitates cleaning and
repairs.
7.3.3 The size of the firewater sump shall be such that the smaller side
is at least equivalent to six times the diameter of the largest
suction pipe. The suction pipe (s) shall be located along the
central longitudinal axis of the sump and the positioning of the
pipes shall be such that no pipe is within a distance of twice its
own diameter from another suction pipe or from the wall of the
sump.
7.3.4 Where the Fire pump(s) draw water from the reservoir under
suction lift conditions the two compartments shall be connected
to a common sump through sluice or gate valves. The suction
arrangement of the Fire pump (s) shall be as indicated in rule
7.4.1.8, 7.4.1.9, 7.4.1.10 and 7.4.1.12 hereunder.
7.3.5 In case of dual purpose reservoirs catering to fire water and
general water requirements the general water pumps shall draw
their supply from a separate sump which shall be connected only
to the fire water sump, the interconnection being so located that
the effective quantity (as defined above) of water available in the
reservoir for fire water requirements below the level of the
interconnection is atleast equivalent to the quantities indicated in
Table 1. Incoming mains shall be connected to Firewater
Compartments and only overflow of firewater compartments
should go to process.
7.3.6 Where the reservoir provides positive suction for the fire
pump(s) in terms of the note under rules 7.4.1.11, tapping shall
be taken from both the compartments and shall be connected

NOTES 1.
In case of High Hazard (B) risks where the aggregate pumping
capacity required in terms of the above Table or of rules 7.4.1.4.2,
7.4.1.4.4, 7.4.1.4.5 and 7.4.1.4.6 hereunder exceeds 1,640 m3/hr.,
larger capacity pumps are acceptable provided the capacity of the
largest pump does not exceed 25 % of the aggregate installed
pumping capacity is disrupted when any pump is in-operative.

where double headed hydrants are used throughout the risk so that
the total number of hydrants (counting a double headed hydrant as
two hydrants) is about double the number of hydrants required as per
the general requirements of this Manual, a double headed hydrant
may be regarded as a single hydrant only.
7.4.1.4.2
Where storage tanks containing flammable liquids are
protected by a medium velocity water spray system tapped from
the hydrant service, the water requirements of the spray system
shall be calculated for tanks located in a common dyke which
have the largest aggregate shell surface area at a rate of 10 litres
/minute/m2 of tank shell surface area except where the system
has been designed to comply with the provisions contained in
N.B 4 under rule 7.6.19 (mandatory protection) in which case
the rate of flow can be reduced to 3 lpm/m2).
Even in the case of tanks located in separate dykes, the shell
surface area of all tanks located within a distance of 15 m (or
the diameter of the larger tank if the same is more than 15m)
shall be aggregated and the water demand of such cluster of
tanks shall be calculated at the rate of flow indicated in the
foregoing paragraph.

foam system shall be equivalent to that required by the largest
protected tank at a rate of 5 litres/minute/m2 of liquid surface
area for fixed roof tanks and 12.2 lpm/m2 of rim seal in case of
floating roof tanks.
Other conditions regarding supplementary hose stream
protection, pumping capacity etc., would remain the same as for
water spray protection.
7.4.1.4.4 Where spheres/bullets are protected by a medium velocity water
spray system tapped from pressurised hydrant service, water
requirements of the spray system shall be determined as under Taking into consideration the configuration of bullets/sphere,
the one which has the largest number of other bullets/spheres
within R +15 M of the centre thereof shall be selected. The
water demand shall then be worked out at the rate of 10
L/min/M2 of the aggregate shell surface area of the
bullet/spheres concerned and all bullets/spheres within R + 15
M of the centre thereof.
Water application may be reduced to 5 LPM/M 2 where the
bullets/Spheres coated with approved passive materials

capacity shall be equivalent to the former.
Note: For design criteria of medium velocity water spray system
reference shall be made to committee's rules for water spray
system.
7.4.1.4.5 Where the plants and other facilities are protected by medium
velocity water spray systems, tapped from hydrant service,
water requirement of the spray system shall be determined as
per Committee's rules for water spray systems. Water
requirements of the spray systems worked out as above shall
then be loaded by 4,500 LPM for supplementary hose stream
protection.
If the total water requirement for spray protection and hose
stream protection worked out as above exceeds the
requirements of the hydrant service as per Table 2, the
pumping capacity shall be equivalent to the former.
7.4.1.4.6 Where transformers are protected by high velocity water
spray system tapped from hydrant system, water requirements
of the spray system shall be determined as per Committee's
rules for water spray system. Water requirement of the spray
system worked out as above shall then be loaded by 1,750
LPM for supplementary hose stream protection.
If the total water requirement for spray protection and hose
stream protection worked out as above exceeds the
requirements of the hydrant service as per Table 2, the
pumping capacity shall be equivalent to the former.
7.4.1.4.7 Where plants and other facilities are protected by
sprinkler system tapped from the pressurised hydrant
service, water requirement of the sprinkler system shall
be determined as per the Committee’s rules for sprinkler
system.
If the total water requirement for sprinkler system
exceeds the requirement of the hydrant service as per
Table 2, the pumping capacity shall be equivalent to the
former.
7.4.1.5
Pumps shall be capable of furnishing not less than 150 % of
rated capacity at a head of not less than 65 % of the rated
head. The shut-off head shall not exceed 120 % of rated head
in the case of horizontal pumps and 140 % in the case of
vertical turbine type pumps.
7.4.1.6
Each pump shall be provided with a plate giving, in the case
of centrifugal pumps, the delivery head, capacity and the
number of revolutions per minute and in the case of
reciprocating pumps, the diameter of the steam cylinders and
water plungers and the length of stroke as also the ratios of
the effective aggregate areas of the suction and the delivery
valves to the area of the water plungers.
7.4.1.7
In case of electrically driven pumps it is recommended that
compression ignition engine driven stationary pump of
similar capacity be installed as a standby and vice versa.
However, where the hydrant service consists of more than
one pump, not more than half the total number (total number
+ 1 in case of odd number) of pumps shall have prime
movers of one type.
(The above provision is not applicable to systems
commissioned before 1982).
Notwithstanding the above, if power to motorised fire pumps
is obtained from two sources, one of which is a captive
generating plant located in a block either 6 m away from all
surrounding buildings, where this is not feasible, segregated
from adjoining building in a manner indicated in rule 7.4.3.1
more than half the total number of pumps may be of the
electrically driven type.
7.4.1.8
Each fire service pump shall be provided with an independent
suction pipe without any sluice or cut-off valves therein,
unless the pump is situated below the level of the water
supply in which case sluice or cut-off valves would be
essential.
Where the water supply has fibrous or equally objectionable
matter in suspension or mud and/or sand liable to cause
accumulation in the installation, suction pipe(s) shall be
installed in a jack well fed through a culvert from the main
water supply. At the supply end of the culvert, a sluice or
gate valve shall be provided.
NOTE - The suction pipe shall be connected to the pump inlet
through an eccentric reducer to avoid air pockets.
7.4.1.9
The diameter of the suction pipe shall be such that the rate of
flow of water through it does not exceed 90 m. per minute
when the pump is delivering at its rated discharge. If,
however, the pump is situated below the level of its water
supply, the diameter of the suction pipe/header shall be based
upon a rate of flow not exceeding 120 m. per minute.
7.4.1.10 Where the pump is to operate under suction lift conditions,
the Net Positive Suction Head (NPSH) available at site shall
be 0.50 m in excess of the actual value required at 150 % of
the duty point as per the manufacturer’s curve of the pump.
NOTE – For the purpose of the above, NPSH available at site
shall be computed by deducting the sum of the static lift
(measured from the ‘low water level’, defined in rule 7.3,
upto the centre line of the pump) and friction loss in the
suction pipe and fittings from atmospheric pressure.
7.4.1.11 Fire Pumps in High Hazard (B) category occupancies shall be
provided with positive suction and automatic starting devices
capable of sequential starting of the pumps. The pumps shall
be connected to audible alarm such as hooter or a siren
located in a prominent place outside the pump house. Where
there is a central fire station in the premises, additional alarm
point shall also be provided in the fire station.
The pumping arrangement shall also incorporate Jockey
Pumps to take care of system losses. The capacity of the
Jockey Pumps shall neither be more than 5 % of the installed
pumping capacity nor less than 3 % thereof (with a minimum
of 10.8 m3/hr.) unless the aggregate installed pumping
capacity is in excess of 820 m3/hr, in which case the capacity
of the Jockey Pump (s) shall be not less than 25 m3/hr plus 1
% of the installed pumping capacity in excess of 820 m3/hr.
Installation of Jockey Pumps also helps to prevent hydraulic
surges.
7.4.1.12 In the case of Light, Ordinary and High Hazard (A) category
occupancies, when the pump is above the level of its water
supply, there shall be a foot valve and a `priming'
arrangement, the latter consisting of a tank (having a capacity
at least three times that of the suction pipe from the pump to
the foot valve subject to a minimum of 1000 litres) connected
to the delivery side of the pump by a metal pipe having a
minimum internal diameter of 100 mm with a stop valve and
a non return valve therein of the same size.
A reliable independent filling arrangement and a level
indicator shall be provided for the priming tank and,
wherever feasible, a continuous overflow arrangement shall
be provided in order to ensure that the tank is always full. It
is recommended that for pumps taking suction from a stored
water supply, a vortex plate shall be installed at entrance to
the suction pipe.
Wherever circumstances permit, the pumps shall preferably
be fixed below the level of the water supply (positive
suction). If the pumps are automatic in action, they shall
necessarily be so fixed. However, if the priming
arrangements are such as to ensure that the suction pipe shall
be automatically maintained full of water notwithstanding a
serious leakage therefrom (the pump being automatically
brought into action to replenish the priming tank should the
latter be drawn upon at a greater rate than the rate at which it
is fed from any other source), positive suction may not be
insisted. In such cases, the capacity of the priming tank need
not exceed 450 litres and the diameter of the priming pipe
need not exceed 50 mm. Jockey Pump(s) of capacity
indicated in rule 7.4.1.11 shall, nevertheless, be provided in
systems where the main pumps are automatic in action.
Where pump(s) are automatic in action they shall be
connected to audible alarm such as hooter or siren located in
a prominent place outside the pump house. Where there is a
central fire station in the premises, additional alarm point
shall also be provided in the fire station.
NOTE - For the purpose of rules 7.4.1.8, 7.4.1.9, 7.4.1.11 and
7.4.1.12 a pump shall be considered as having positive
suction only if the quantity of water in the reservoir above the
low water level (see N.B. under rule 7.3) or the top of the
pump casing, whichever is higher is equivalent to the
requirements of Table 1.
7.4.1.13 Each pump shall be provided with a non-return valve and a
sluice valve on the delivery side, the sluice valve being
installed on the upstream side of the non-return valve. A
pressure gauge shall also be provided between the pump and
the non-return valve. The size of the non-return valve and cut
off (sluice) valve shall not be less than the size of the initial
delivery pipe and, in no case, less than the delivery outlet of
the pump. Further, as Butterfly Valves can create
turbulence adversely affecting the pump performance no
Butterfly valve shall be installed on the suction side.
7.4.1.14 When the premises are also protected by sprinkler installation
having elevated tank(s) as one of the main sources of water
supply, and where the arrangement for filling the tank(s) is
taken from the hydrant service, the connection shall be taken
directly from the pump to the top of the tank (through a stop
valve) and not through the hydrant mains. (See fig. below)
7.4.1.15 Pumps shall not be installed in open. The pump rooms shall
normally have brick/concrete walls and non-combustible
roof, with adequate lighting, ventilation and drainage
arrangements.
The pump room shall be so located as to be both easily
accessible and where any falling masonry and the like from
other buildings occasioned by fire or other cause, cannot
damage the pump room. Normally, pump rooms shall be
located 6 m away from all surrounding buildings and
overhead structures. Where this is not feasible the sides of
the pump room falling within 6 m of the surrounding
buildings shall be blank masonry walls of 355 mm thickness
and the roof of the pump room shall be of RCC. Likewise,
when the pump room is attached to a building a perfect party
wall complying with the committee's regulations shall be
constructed between the pump room and the attached
building, the roof of the pump room shall be of RCC
construction at least 100 mm thick and access to the pump
room shall be from the outside. In no case shall the pump
from be sited within a building occupied for any other
purpose.
N.B. for High Hazard (B) occupancies, in addition to the
above provisions, the pump room shall be located 30 m clear
of all equipment where flammable fluids having flash point
below 65o C are handled and/or stored and 15 m clear of
pipes/pipe racks (of other than water.). This provision shall,
however, not apply to systems commissioned before 1982.

* 80 mm diameter terminal and/or riser mains shall be taken
as 100 mm diameter mains for this purpose.
NOTES -
1) In calculating the number of hydrants in the system, a
double headed hydrant shall be counted as two, a fixed
monitor of 63 mm size having nozzle bore of 32 mm
shall be counted as three, a fixed monitor of 75 mm size
having nozzle bore of 38 mm shall be counted as four
and a fixed monitor of 100 mm size having nozzle bore
of 45 mm as six hydrant points.
In case of Oil Refineries, Petrochemical complexes or
other risks, where double headed hydrants are used
throughout the system so that the total number of
hydrants (counting a double headed hydrant as two
hydrants) is about double the number of hydrants
required as per the general requirements of this Manual,
a double headed hydrant may be regarded as a single
hydrant only.
2) For High Hazard occupancies, the hydrant system shall
be hydraulically so designed that when half the
aggregate pumping capacity is being discharged at the
farthest/hydraulically most remote point and the other
half in the most vulnerable area enroute, a minimum
running pressure of 5.25 kg/sq. cm is available at the
former point and the rate of flow of water does not
exceed 5 m/second anywhere in the system.
In case the hydraulically most remote point is the area
determining the fire pump capacity, the entire aggregate
pumping capacity shall be considered as being
discharged at this point at a minimum running pressure
of 5.25 kg/cm2 and the hydrant system shall be so
designed that the rate of flow of water does not exceed 5
m/second anywhere in the system.
In case the hydraulically most remote point happens to
be light/ordinary hazardous, pressure requirement at this
point can be restricted to 3.5 kg/cm2. However pressure
available at the high hazard area immediately preceding
the ordinary/light hazard area must be 5.25 kg/sq. cm.
3) For Light and Ordinary Hazard Occupancies having
more than 55 points, either of the following methods
may be followed a)
The hydrant service be constituted of single or more
than one inter-connected hydrant systems, each with
its individual pump set according to Table 2 and
water supplies equivalent to the aggregate
requirements of the number of pump sets installed.
b) A single hydrant system may be installed provided,
it is hydraulically designed (where the highest
hydrant is located more than 20 m above ground
level, pre calculated systems shall not be accepted)
as per the parameters indicated in N.B. 2 above,
except that minimum running pressure shall be 3.5
kg/sq. cm. Instead of 5.25 kg/sq. cm (minimum
diameter of the pipe used in the ring mains shall
however not be less than 100 mm).
4) In the case of riser mains in storeyed buildings and in
locations where it is not feasible to lay a ring main, a
terminal main may be provided, but in no case shall the
number of hydrants on such terminal mains exceed 5.
A terminal main of 80 mm diameter shall not feed more
than one hydrant, that having a diameter of 100 mm shall
not feed more than two hydrants, that having a diameter
of 125 mm shall not feed more than three hydrants and a
main of 150 mm shall not feed more than five hydrants.
The Committee may, at their discretion, permit more
than five hydrants on riser mains of storeyed structures.
5) In case of systems designed on the basis of pressure loss
calculations, the piping routes selected along with ‘nodal
point’ commemorating with the pressure loss calculation
sheets should be distinctly marked in the drawing.
7.5.11
Cut-off (Isolating) valves are necessary to obtain the best
possible pressure at the seat of fire as they enable a damaged
portion of the installation to be isolated whilst full pressure is
available throughout the remainder. These valves are
distributed according to the general layout of the installation
and not according to fixed rules. For this reason, the
proposed position of these valves shall have the prior
approval of the Committee.
Cut-off valves shall conform to IS: 780, PN 1.0/IS: 2906,
Class 2 or AP9600 in case of Cast Steel Valves of class 150.
NOTES 1. In case of system having working pressure in excess of 7
kg/cm2 PN- 1.6 rating would be necessary for valves
conforming to IS: 780 and Class 3 for those conforming
to IS: 2906. Cast Steel valves of class 150 are, however,
acceptable irrespective of the working pressure of the
system.
2.
Other types of valves like rising spindle valves may be
used, subject to prior approval of the Committee.
3.
Butterfly valves also can be accepted subject to the
condition that the valves of diameter exceeding 150 mm
shall necessary be of gear operated.
7.5.12
All cut-off valves shall be of the right-hand type and
enclosed in properly constructed surface box, at least 1 m2 so
as to allow for broken joints being easily remade. The top of
the surface box shall be 80 mm above ground level, except
where it is locate on a road. Valve wheels shall have an
arrowhead engraved or cast thereon showing direction for
turning `open' and `close'.
7.5.13
It is recommended that the position of the surface box be
indicated by an iron plate painted `fire red' with distinct
lettering. Such plates shall also show the `open' and `close'
direction as cast or indicated on the valves and the serial no.
of the sluice valve also should be indicated.
7.5.14
In case of installations in earthquake prone zones, some form
of flexible couplings approved by the Committee shall be
used for jointing purposes.
7.6

7.6.1
Water shall be available immediately to all hydrants/fixed
monitors at all times, with all cut-off valves being kept open.
Before final inspection the hydrant system shall be flushed
thoroughly.
7.6.2

valves. A single control valve will not be permitted.
7.6.8
Hydrants shall be easily accessible, storage of any kind on or
around the hydrant being prohibited. Where hydrants are
situated in remote locations, they shall be approachable by
means of paved pathways.
7.6.9
Hydrants located in situations where they are likely to be
damaged by vehicular traffic shall be suitably protected on all
sides against possible damage.
7.6.10
Hydrants shall be located bearing in mind the attendant fire
hazards at the different sections of the premises to be
protected and so as to give most effective service. They shall
be so distributed as to provide protection for the buildings on
all sides and need not necessarily be equidistant from each
other.
Advantage shall be taken of convenient door and/or window
openings to place hydrants so that only a minimum length of
hose is required to reach the openings through which fire
may be attacked. In case of continuous blank walls, suitable
provision shall be made on the walls near hydrant posts for
easy access inside the premises.
7.6.11
At least one hydrant post shall be provided for every 60 m of
external wall measurement in case of Light Hazard
Occupancy, for every 45 m in case of Ordinary Hazard
Occupancy and every 30 m of external wall measurement or
perimeter of unit battery limit in case of High Hazard

Measurements shall be calculated on the total length of walls
of all buildings/perimeter of all battery limits to be protected
except in the case of opposite buildings (other than those of
High Hazard category) within 22.5 m of each other, where
the measurement of the shorter opposing wall may be
omitted.
Further, all hydrants and monitors should be serially
numbered.
NOTE: Notwithstanding the above, hydrants protecting
utilities and miscellaneous buildings in High hazard risks
may be spaced at 45 m.

any part of a building is normally used for storage purpose or
where hazardous processes are carried out, there shall be two
single or one double headed hydrant within 15 m of the
building, the layout being such that two jets of water can be
played simultaneously on the highest point of the roof.
In case of Buildings/Plants occupied for High Hazard process
or storages, the above-specified distance may be increased to
22.5 m.
In case of buildings having roofs other than RCC, it is
advisable to provide hydrants at the roof level along with
access staircases in order to fight the fire by breaking open
the roofs, if necessary.
7.6.13
Hydrant heads shall be positioned at distances not less than 2
m from the face of the building or edge of the storage plot to
be protected except in the case of high hazard occupancies
wherein the hydrant heads shall be located not less than 7.5
m from the face of the building, edge of the storage plot or
from the plant battery limits.
7.6.14
In case where, owing to the size or layout of the building, or
building being divided by internal walls, any point within the
building is at a distance of more than 45 m from an external
fire hydrant, an internal hydrant system shall be provided so
that no portion of the floor is more than 45 m from an
external hydrant or 30 m from an internal hydrant.
In case of large switchyards, where it is not feasible to lay
internal hydrants, alternate hydrants may be replaced by
monitors of suitable size.
N.B: Distance of 45 m indicated above shall be increased to
60 m for light hazard occupancies and reduced to 30 m for
high hazard occupancies.
7.6.15
In case of storeyed buildings, satisfactory access shall be
provided to all parts of each floor by means of incombustible
internal or external staircases. Normally, a minimum of two
such staircases will be needed per compartment, but in case
the area of the compartment exceeds 2,000 sq. m., an
additional staircase shall be provided for every additional
1,500 sq. m. or part thereof. On the other hand, if a
compartment has a floor area of less than 500 sq. m., one
access staircase shall be acceptable. The access staircases
shall be so located that, as far as possible, no part of each
floor is more than 30 m from the nearest staircase. Where it
is not possible to locate the staircase in the aforesaid manner,
the Committee may suggest alternative methods for
protection of such large upper floors. External access
staircases shall be open to sky.
The staircases shall conform to the following -
7.6.15.1 Internal staircases shall be so located that atleast one of its
enclosing walls is an external wall of the building. A door
opening shall be provided in this external wall at ground
floor level. The enclosing walls shall be of brick work atleast
230 mm thick or reinforced concrete atleast 100 mm thick
carried through and atleast 450 mm above the roof of the

7.9
FIRE FIGHTING PERSONNEL:
7.9.1
As the efficiency of a hydrant service and/or of internal
appliances depends upon the manner and speed with which
they are brought into use and the ability with which the effort
is directed, a squad consisting of watch and ward personnel,
fire pump men and departmental supervisors and/or
operatives trained in the operation of the fire service shall be
maintained on the premises round the clock. The number of
personnel constituting the squad shall necessarily depend
upon the size of the risk, but in no case shall be less than
eight trained persons be available at any time during the day
or night. Minimum number of trained persons required may
be further reduced to six in case of automatic pressurised
hydrant systems.
7.9.2
Squad leaders shall preferably be recognised government
institution trained and their usefulness would be considerably
enhanced if they reside on the premises.
7.9.3
Squad personnel shall be provided with clothing and
equipment including helmets, belts and boots, preferably
gumboots.

the brigade shall be prepared and copies supplied to each
squad leader as well as pasted in convenient places
throughout the premises, so as to be quickly available for
reference in case of emergency.
7.9.5
Practice drills shall take place weekly and it is a condition of
the approval by the Committee to the discount for hydrant
service that wet drills shall be carried out at intervals of not
more than a fort-night and that the entire squad on duty shall
turn out during the visits of the committee’s Inspectors.
During wet drills, hydrants (including those of upper floors),

7.9.6
so that the efficacy of these appliances would be
automatically checked and any defects observed, set right.
7.9.7
A register shall be kept as per Appendix V showing details of
all practices and defects, if any, reported in the installation.
This register shall be open to examination by the
Committee’s Inspectorate.
7.9.8
The services of the pump man (see 7.10.1.1.1) could be
profitably utilised for the maintenance of all fire fighting
appliances (including hand appliances - See 4.1.5.1.1). He
shall also be thoroughly conversant with the locations of all
appliances, particularly of hydrant cut-off valves so that in an
eventuality he would be of assistance to the
factory’s fire brigade or the Town’s fire brigade.
7.9.9
Keys of all doors in the factory premises shall always be
available at the main gate.
7.9.10
It is recommended that fire pump room(s) and the main
gate(s) of all factory premises be connected to all
manufacturing sections through the internal telephone
system. Telephones interlinked to this system may
also be put up in proper cubicles at convenient locations near
godown ranges and other strategic points. This would effect
saving of valuable time in an emergency to alert the fire
fighting personnel and the pump man.
7.10
MAINTENANCE:
7.10.1
PUMPS:
7.10.1.1 GENERAL:
7.10.1.1.1 A trained pump man (see 7.9.8) shall be available on all

shall be put in hand and carried out immediately.
7.10.1.2
STEAM PUMPS:
7.10.1.2.1 The steam cylinders of pumps shall always be kept warm
and efficient draining arrangements provided.
7.10.1.2.2 A minimum of two sets of piston and bucket rings shall be
provided.
7.10.1.2.3 Small parts such as snifting valves, cushioning valves and
petcocks shall have special attention because faults in these
valves cause the pump to knock badly and lose efficiency.
7.10.1.3
ELECTRICALLY DRIVEN PUMPS:
7.10.1.3.1 The bearing grease cup shall be checked once every week
and refilled with fresh grease, if necessary.
7.10.1.3.2 Starter contacts shall be cleaned once every week.
7.10.1.3.3 Insulation resistance of pump motor circuit shall be

be maintained.
7.10.2 MAINS:
7.10.2.1
Hydrant mains shall be tested once a fortnight with a pump
delivering at its maximum pressure, with all hydrant valves
closed and, thereafter, a running test with two or more hose
lines each 30 m long operating shall be carried out. This
checks the efficiency of the pump as well as the tightness of
the hydrant mains (See Rule 7.9 also).
7.10.2.2
All cut-off valves shall be operated and oiled, if necessary,
once a month.
7.10.2.3
Cut-off valves shall be thoroughly overhauled annually to
remove sludge and other foreign matter collected in the
valve seating.
7.10.3
HYDRANTS:
7.10.3.1

good condition and all brass parts polished.
7.10.3.2
Spare washers shall be kept for hydrant valve seats.
7.10.3.3
It is recommended that the painting of standpoints be carried
out annually.
7.10.4
HOSE PIPES AND NOZZLES:
7.10.4.1
All hose boxes/hose stations shall be inspected externally
once every week to ensure that the equipment installed
therein is intact. Further, the hose boxes/hose stations shall
be cleaned internally and externally once a month.
7.10.4.2
When the hose gets worn out at the tail end of the
coupling(s), it is permissible to cut the end(s) of the hose.
However should the lengths of the hose after cutting(s) fall
below 90 percent of its original, i.e. 15 m or 7.5 m the hose
shall be discarded.
7.10.4.3
A Hose Register shall be kept showing the history of each
length. Information such as date purchased, date brought
into use, date cut (if reduced in length), is useful and a
column shall be provided for remarks by the Committee’s
Inspectors to whose inspection the Hose Register shall be
open.
7.10.4.4
Any hose becoming inefficient through use, neglect or from
any other cause, shall be discarded.
7.10.4.5
Fire protection hose shall not be used for purposes other
than fire protection and drill. All concerns are advised to
keep a supply of cheap hose for watering paths, washing out
or filling boilers, etc. Such hose shall not be mixed with
fire protection hose but kept in an entirely separate place.
7.10.4.6
It is recommended that hose couplings and branch pipes be
polished once a fortnight.
7.11
Considerable diversity of practice has been noticed in the
attention paid to the drying and storing of hose and the
following suggestions in this connection shall be carried
out:
After use, hose to be thoroughly washed in clean water and
then thoroughly dried. A rack or some similar contrivance
atleast 10 m high to be provided so that, after cleaning, hose
may be suspended to drain and dry evenly.
This is to be done in the shade and not in the sunshine so
that the hose is evenly dried inside and out. Care to be
exercised that it is not removed until it is thoroughly dry in
all places. The hose to be then thoroughly brushed with a
hard bristle or wire brush, and re-rolled, care being taken to
choose a dry and clean place whereon to roll it; and replace
in the boxes or hose stations.
Care to be taken after washing that the hose does not touch
the ground, where it might be soiled.
Hose to be rolled up evenly and carefully, the female or
spring coupling end being in the centre. In this manner the
spring clips, when grasped one in each hand, form a `reel’
and the hose can be quickly run out in the event of fire. OR
ALTERNATIVELY
The hose to be doubled in the centre of its length and rolled
up evenly from the fold. Both the Male and Female
couplings will then be on the outside of the roll. This
permits the nozzle being attached to the hose while being
stored in readiness for use, and the hose runs out without
twisting.
7.11
MEASURES TO BE TAKEN WHERE THE INSTALLATION
IS FOR ANY REASON TEMPORARILY INOPERATIVE:
7.11.1
Where the installation is expected to remain inoperative for a
period exceeding 24 hours, prior sanction shall be obtained
from the Committee.
7.11.2
If any component of the hydrant system is to be replaced for
any reason whatsoever, the entire system shall not be
rendered inoperative but the particular section only shall be
isolated by closing the necessary cut-off valves. If, however,
it is not possible to complete the replacement before
nightfall, the cut-off valves shall not be left closed overnight.
Instead, blank flanges shall be provided at the point where
the component has been removed so that the entire system,
other than the component, which has been removed, would
remain operative through the night.
7.11.3
Only one compartment of the reservoir shall be emptied out
at a time of cleaning or repair work.
7.11.4
If the foot valve of the suction line is removed for
cleaning/repairs, it shall, as far as practicable, be replaced
before nightfall.
7.11.5
If the pump is expected to be inoperative for more than 72
hours, every effort shall be made to connect the service water
supply to the hydrant system for the duration the pump is
inoperative.
7.11.6
If the hydrant service is to be extended, the extended portion
shall be first laid and, thereafter, the connection between the
existing system and the extension shall be carried out
expeditiously, so that the entire system is not left inoperative
overnight.

NOTE: - In applying this table the height of the Highest Sprinkler above
the Pressure Gauge must be ascertained and the pressure to be
allowed for such height will be obtained by reference to the table.
For example, if the gauge records a pressure of 4.25 Kg./cm2, and the
highest sprinkler is 28 m above the gauge, there will be a pressure of,
say, 1.45 Kg./cm2 on the highest sprinkler.
