am delighted to note that Inspection Circle, Jabalpur is publishing the Compendium on Fire.
I find that Inspection Circle, Jabalpur has really made a good effort to collect the complied instructi ons on Fire safety measures and different orders issued by the Governmen t of India and B.S.N.L. together with its own experi ence of fire investigations in
B.S.N.L. I am sure that this effort will be very useful as reference guide for general awareness of the B.S.N.L. staff.
I wish that Inspection Circle, Jabalpur will continue with same in itiative and zeal to publish the compendium on Fire at such time when latest technol ogies are being inducted in B.S.N.L. As it is said prevention is better that cure, the implementation of fire safety measures, are ardent need of the hour.
I congratulate the co-ordinator for making such an excellent effort for the benefit of B.S.N.L. The compendium on Fire will be useful for others who will like to deplo y the instructions contained in the compendium on fire in their organization.
I wish this effort achieves grand success .

I am glad to know that Inspection Circle, Jabalpur is bringing a comprehensive compend ium on the Fire Prevent ion in Telecom Installations which is a very essential handb ook for every Telecom Personnel.
The hazards of Fire in telecom installations are enormous and require to be controlled effectively. More important are the steps required to be taken to prevent occurrences of fires so that maximum protecti on against their out break is available. The ignorance oft he staffin dealing with such hazards cost us dearly.
Th is compendium addresses all necessary requ irement s like safety precautions to be adopted to prevent fire occurrences, action required to be taken immed iately on noticing a fire, steps to be followed during the calamit y etc. There is detailed description about the importance of fire drill / training by Fire bridge personnel which is to be observed in all Telecom Installations involv ing all staff.
The compendium contains check list for inspection of fire safety equipments, fire hazard promoters as well as a comprehen sive questionnaire to assist in accurate fire invest igation. I would like that all officers designated by Circles as fire officers shall carry out annual inspection referring this compendium and Heads of Circles shall personally monitor the status.
I am sure that this compendium will prove to be a usefu l guide to all in dealing with matters concerned with fire hazards .
I convey my best wishes to Inspection Circle team on the occasion of release of this comp endium .

It gives me immense pleasure to learn that the Inspection Circle ja balpur is releasing a 'Comp endium on Fire' .
There have been many mishaps in telecom network due to the sudden outbreak of fire and huge losses which were incurred'could have been minimized ifadequate knowhow about the different protective measures to be ado pted were known to the sta ff on duty .
There is increased risk of fire inciden ces in today's telecom netw ork due to the high concentration ofdifferent types of equipments/e lements at a single pla ce. The staff on duty reacts differently on witnessing the panic created on the outbreak of fire and their efforts in extinguishing the fire are not fruitful to the desired effect.
I am sure that this Compendium will prove to be a highly necessary reference handbook to all the telecom officials.
I convey my best wishes to the Inspection Circle on the occasion of release ofthis Compendium.

I am extremely happy to know that Inspection Circle Jabalpur has compiled a
'Compend ium on Fire' in Telecom Installations.
A fire incident in a telecom netw ork causes unimaginable havo c in terms of
disruption ofserv ices, great inconvenience to customers and public in general and requires
huge expenditure to revert back to norm al working conditions. Even a few hours of
disruption oftelecom network incurs a mammoth loss ofrevenue.
H is very es sential that all staff must have awareness about the precaut ions to be
taken on regular basis to avoid any fire incident and in case ofany mishap , they mu st know
the correct way to deal with such situations to minimize the loss. Thi s compendium on Fire
gives an apt description about actions to be taken on outbreak offir'e. Simple precautionary
measures to be adopted by staff for prevention of fire incidents would go a long way in
main taining the network in perfect ord er.
I am certain that this compendium will prove to be a very useful reference to
every Telecom official.
I congratu late Inspection Circl e on the occasion of release of this very useful
compendium.

I am happ y to learn that Inspection Circle, Jabalp ur has compiled a compendium on 'Fire in Telecom Installations'.
There have been num erous instance of heavy losses to equi pments and sever disrup tion is services due to sudden outbreak offire in telecom prem ises. Effort s put is by our ded icated staff over the years in insta lling and astutely maintaining the telecom systems are abruptly nullified during such nightmares .
Due to pressi ng day-to-day opera tiona l requirements in today 's challenging telecom scenario, preparedness to seriou sly understand the nuances of fire protection and what to do in case of a sudden and unexpected fire incident often takes back sea t. Th is compendium prepared by Inspect ion Circle is comprehensive and contains very usefu l informa tion about fire protection methods and what to do iffire takes place.
What to-do methods have been devised in the compendium in a mann er which is very easy to understand and follow even by a non professio nal? Various protective measures have been highlighted , including demonstrating it practica lly through regu lar fire dri lls by Fire Bridge personne l. Inclusion of a very good questionna ire on fire investigations will really help in accurate findings on the caus e of the fire.
I am sure that this compendium will be a very useful reference to every telecom officials.
I wholeheartedly place on record my appreciation to Inspection Circle on the occasion ofrelease ofthis compendium.

It gives me immense pleasure to learn that Inspection Circle, Jabalpur is releasing
a compendium on Fire hazards in Telecom Installations.
In the past heavy losses were incurred due to fire hazards in Telecom Installations.
In most of the cases, it has been observed that there is lack of knowledge on fire methods
and also lack of preparedness to handle such incidents.
This compendium from Inspection Circle addresses the causes, which are likely
to induce fire and the methods to be take n to counter the same . It also deals with the
precautions to be taken to prevent occ urrence of such incidents. The importance of
attending fire safety drill given by Fire Brigade perso nnel as well as a questionnaire to be
used during investigation on fire incide nts are included in this doc ument.
I wish the release ofthis compend ium a great success and congratu late Inspection
Circle for bringing out this highly useful handbook which will be beneficial to each and
every Telecom officials.

I am very happy to know that Inspection Circle, Jabalpur is releasing a very useful and ideal compendium on fire in Telecom Installation.
Fire is the most lethal destruc tive element known and inflicts unimaginabl e damage and loss to Telecom Installations which is very hard to recover. It is, therefore, important that everyo ne should have a sound knowledge about various methods on prevention of the fire and the immediate actions to be initiated on noticing a fire, etc.
Operation and maintenance staff who keep busy in their allotted works somet imes do not possess enough knowledge about fire prevention and its consequences and tend to act in a hurry on the first outbreak of fire, resulting in further escalation to damages. This compendium on fire brought out by Inspection Circle is an exce llent reference book dealing with all concerns about fire incidence in Telecom Installations.
This compendium also highlights required details on personnel safety during outbreak offire which is highly appreciable. In addit ion to fire drill, I would sugges t the Heads of the Circles to depute their staff for training on the subject regularly.
I congratulate Inspection Circ le on the occasion of release of this very essential compendium.

FOREWORD
Fire protection is the study and practice of mitigating the unwanted effects offires. It involves the study of the behavior, compartmentalization, suppression andinvestigation of fire and its related emergencies, as well as the research and de-velopment, production, testing and application of mitigating systems. There havebeen numerous instance of heavy losses to telecom equipments and sever dis-ruption in services due to sudden outbreak of fire in telecom premises.
Fire protection has three major goals:
l Continuity of operations-on a public scale, this is intended toprevent the interruption of critical services necessary for thepublic welfare.
l Property protection-on public, this is intended to prevent areawide conflagrations.
l Life safety.
This compendium contains very useful information about fire protection meth-ods and also suggests what to do if fire takes place. The methods have beendevised in the compendium in a manner which is very easy to understand. Vari-ous protective measures have been highlighted. Inclusion of a very good question-naire on fire investigations may be useful in accurate findings on the cause of thefire.
This assumes more importance as telecommunication has become one ofthe most essential infrastructure for the economic growth. There is concentrationof state of the art switches both for fixed lines as well as mobile in a compactspace. This requires all precautions to be taken to prevent fire hazards which mayinvolve not only huge losses but also disruption of communication for long periods.
This compendium covers various aspects to analyse likely causes of fireand the preventive measures to be taken.. We have complied instructions on Firesafety measures and different orders issued by the DOT/ B.S.N.L. This compen-dium addresses all related issues like safety precautions to be adopted to preventfire occurrences, action required to be taken immediately on noticing a fire, stepsto be followed during the calamity etc.
I am sure that the compendium will prove to be a very useful reference bookto all telecom officials

1.2 Preamble:
The geographical and climatic condition of the country
makes many different disciplines and attitudes in regard to design
of buildings and selection of materials. Good housekeeping, gen-
eral tidiness, control on combustible materials and awareness about
surroundings may certainly minimize the fire risks. In case of fire
incidence, provisioning of efficient fire detection and alarm system
helps in initiating timely action to control the fire. Good quality and
proper quantity of fire fighting apparatus provides strength against
fight with fire. Fixed and portable fire extinguishing apparatus fully
charged and in working condition should be available in sufficient
number at convenient locations to check the fires in incipient stage.
The norms for fire fighting apparatus should strictly be adhered to.
Fire never discriminates between living and non living. The
living build future and it must be saved on first priority. The building
design must have provision of adequate escape routes for safe
and expeditious exit for the occupants. There should be a system
to broadcast and communicate the information of fire to the agen-
cies concerned immediately. Correct and proper information facili-
tate the fire fighters to take prompt and relevant action. In spite of
many precautions, fire damages properties and lives. Telecom sec-
tor is also a witness of such hazards. To prevent the future occur-
rences of fire incidences in telecom, especially in BSNL, the inci-
dent must be investigated thoroughly for root cause. The Inspection
Circle of BSNL investigates and finds out the cause. An over view
on recent fire cases are given in Appendix A. Inspection Circle is
also reporting to head quarter along with recommendations to pre-
vent fire in future.

CHAPTER – V
FIRE DETECTION AND ALARM
5.0 General:
Prompt detection of an out-break of fire in its incipient stage
and simultaneous operation of fire alarm for quick and correct ap-
plication of fire fighting media, minimizes the loss from fire up to a
great extent. Primary purpose of fire detection system is to respond
to a fire and to transform this information into a visible and audible
alarm which should alert the building occupants. Auto SMS alerts
to concerned senior officers, if available, should be extended.
5.1 Manual Fire Alarm:
Small and medium capacity exchanges not exceeding 2k
lines shall have manual fire alarm system. For the purpose of de-
sired alarm system, the building shall be divided in to a no. of zones.
Where ever manual fire alarm system is provided, the building shall
be divided into number of zones. In multi-storied buildings, each
floor shall constitute one or more zone depending on the area of
the floor.
Fire alarm switches/call boxes shall be mounted at conve-
nient locations in the zones. The call boxes shall be accessible to
all occupants without having to travel more than 22.5 m. The call
boxes shall be so installed that their location is easily noticed from
either direction. The base of call boxes shall be at a height of 1.2 1
m. above the floor level. The manual call boxes shall be colored
RED.
5.2 Automatic Fire Detection System:

false ceiling (attic spaces) if provided, shall constitute separate
zones.
The layout of the detection system shall generally be in
accordance to guidelines contained in IS 2189-1976 as amended
up to date.
The detectors should be of rate of rise heat type and smoke
type. Wherever smoke detectors are provided, a mixture of photo-
electric & Ionization type, will be used. The heat detectors shall
satisfy the tests laid down in IS 2175 as amended up to date (Speci-
fication for heat sensitive fire detectors). The smoke detectors shall
conform to relevant NFPA/UL Standards.
The detector density of smoke detectors in the switch rooms
and OMC room of Electronic Exchanges shall not exceed 25 Sq m.
per detector. In ventilated floor voids, the detector density shall not

air ducts of air conditioning system shall also be covered by detec-
tors. In return ducts, the detectors should be located directly after
the last air extract aperture before the air enters a common duct. In
supply air ducts the detectors should be located sufficiently away
from points of turbulence such as bends, junctions and air inlets.
Detectors in supply & return air ducts shall be connected to sepa-
rate zones.
Whenever automatic fire extinction system is adopted suit-
able cross zoning shall be done in the detection system in order to
avoid unnecessary action in case of accidental triggering of any of
the detectors.
Photo –electric detectors sense the light emitted by the
flames and trigger the fire alarm where as the ionization detectors
sense the smoke and trigger the fire alarm. The Heat detectors
sense due to heat and trigger the fire alarm system. Heat detec-
tors should be installed in the E/A rooms.
The supply air duct of centralized A/C system should be
provided with fire damper and the same should be inter linked elec-
trically with the fire alarm panel. Whenever there is a fire alarm the
fire damper should close and the entire air conditioning system
should shut down.
In the multi-storied building each floor should have a con-
trol panel and along with the diagram indicating the differed zones
and the detectors. Any alarm in the control panel of any of the floor
will be repeated in the Main control panel provided in the fire con-
trol panel or in the entrance lobby of the building.
There are mainly following three functional entities in fire
detection systems
a) Manual call point / (MCP)By breaking the manual call points the
attention of the other people are drawn. This is connected to the
Main control panel. This should be tested periodically.
b) Response Indicators / (RI). Response indicators are to be pro-
vided outside the locked rooms, for detectors in the false floor &
false ceiling areas and they are to be properly sign written.
c) Hooters: Function of all the hooters are to be tested periodically
(Reference BSNL DO No 19-2/2009-PHM/MSE dated 25/07/2009),

munications or extensive damage to equipments.
7.4 Role of Inspection Circle
One of the important function assigned to Inspection circle
is to carryout independent investigation in case of fire in Telecom
installations. On receipt of information of fire incident from DGM or
appropriate authority of the respective circle, the Chief General
Manager, Inspection Circle will register a case and appoint a fire
investigator to know the probable cause of fire and loss to the prop-
erty.
Investigation of fire is carried out in parallel without dis-
turbing the restoration process of services. The answers of all the
questions of questionnaire (given at Annexure-I) are carefully ob-
tained and recorded. Written statements and photographs of the
affected and suspected locations are also being taken in support
of the evidences. The General part of the questionnaire deals with
the action to be taken by the officer on duty. The Engineering part
of questionnaire is dealt with the senior most Engineering Officer
in charge at the time of occurrence of the fire. Clear photographs
of fire incident are invariably being taken prior to any replacement
or repairs.
After receipt of report and after being satisfied on its ex-
amination, the CGM Inspection Circle, Jabalpur forwards the re-
port to the GM (NW-OPS) Fixed Access BSNL C.O. Bharat Sanchar
Bhawan, Janpath, New Delhi (Fax No. 011-23766033) and also
sends a copy of report to the CGM telecom circle concerned.

partment/ higher authorities of BSNL
k Way to the Emergency exit on each floor should be properly
displayed and free from any obstruction.
k Partitions for office space should be restricted to 4 ft height in
order to have clear visibility. Partitions for office area should
not be extended up to false ceiling height
k Concentration of large number of important telecom installa-
tion should be avoided in one particular building
k Major traffic routes carrying Inter Circle traffic (especially meant
for IN, Billing, and SMSC etc.) should be directly fed from NTR
transmission room to respective locations instead of bringing it
to SSA transmission Room and distributing it to other loca-
tions.
k The concept of Auxiliary transmission room/ Centre needs to
be evolved to enable restoration of important systems with mini-
mum down time.
k The switch room and the transmission room should not be made
with have any fire hazardous materials like wood. In case of
rented buildings the doors and windows should be painted with
fire retardant paint.
8.2 Building:
As per CPWD norms the following fire fighting arrangements shouldbe made:
k Provision of wet raiser system with adequate water storage asper requirement.
k Provision of fire extinguisher of latest technology.
k Instead of fixed glass, panel window type glass panels may be
provided so that the smoke can be evacuated immediately.
k Provisioning of adequate space should be there for the move-
ment of Fire Brigade personnel’s around the building. There
should be free access inside the buildings also to enable the
fire personnel to control the fire
8.3 Electrical Fitting:
As far as possible it is better to avoid taking the run way below or
above the window AC units. Or sufficient gap of more than one
meter space should be given.
· All Electrical fittings and wirings should follow the proper specifica-
tion. Any wiring which is being overheated should be specifically
got checked and remedial action be taken.
k Main distribution of A.C supply must be provided with suitable
rating of fuses.
k DCDB panel must be provided in exchange as a part of instal-
lation.

8.4 Air Conditioners :
k Clean the filters of the window A/C units periodically. Choking
the in the filter causes over load to the compressor and many
A/C units get fire due to this problem.
k The window AC should be replaced with split type AC units.
k Where ever window AC is still in use, check that all the window
air –conditioners are properly functional and are being main-
tained properly. Ensure that :

k They do not draw excessive current and the temperature is
maintained in the switch room at an appropriate level. Such
air-conditioners are not supposed to run continuously.
k The change over arrangement between AC units should be
operational.
k The air-conditioners are to be serviced regularly as per sched-
ule.
k As for as possible the inter-locking arrangement with Window /
split AC should also be provided with fire alarm system.
(Reference BSNL DO No 19-30/2008-PHM/MSE dated 30/04/2009),
8.5 Telecom Equipments:
k Power cables for A.C and D.C both, inter-suit wiring and sub-
scriber cables should be laid separately, so that short circuit-
ing and fire does not spread to other cables also.. For laying of
cables, relevant engineering instructions should be followed.
k Barriers should be created at suitable intervals in addition to
the requirement of normal Fire Bye-laws while laying cables.
k Fixing a plate in the MDF room and also in a room of senior
officer mentioning the next date for earth and surge lightening
protector check
8.6 Mock Fire Drill
This will help in identifying any weakness in the evacuation strat-
egy.
Necessary Fire drill should be conducted to ensure proper mobili-
zation of resources and to educate the staff against unfortunate
event of fire and that they understand the emergency action plan.
Side by side, it will cross check the adequacy of the building and
precautions available for prevention of fire accidents.
Nomination of Fire safety officer for each building and conduction
of fire drill exercise once in a quarter is to be monitored by a JAG
level officer. During such drill, they will be able to assess the appro-
priateness of actions and identify problems
Where there is more than one escape route, the fire drills shouldassume conditions in which one or more than one escape routeare obstructed by smoke.
(Reference BSNL DO No 19-30/2008-PHM/MSE dated 02/03/2009)

LIGHTNING PROTECTION AND EARTHING
9.1 Lighting Protection
Lightning is a natural hazard, being the discharge of static
electricity: generated in parts of storm clouds. Some of them dam-
age buildings and a few are injuring people either directly or indi-
rectly by causing fire and explosion.
An Earthing System is an essential part of any electric/
electronic system. The objective of an Earthing System may be
summarized as follows :
(i) To provide safety to personnel during normal and fault condi-
tions by limiting step and touch potential.
(ii) To assure correct operation of electrical/electronic devices.
(iii) To prevent damage to electrical/electronic apparatus.
(iv) To dissipate lightning strokes.
(v) To stabilize voltage during transient conditions and therefore
to minimize the probability of flashover during the transients.
(vi) To divert stray RF energy from sensitive audio, video, control
and computer equipment.
9.2 Requirement for effective Earting
An Earthing system must meet the following specifications :
(i) The resistance to earth must be within the allowable limits for
the particular application.
(ii) The electrodes buried in the ground must be :
a) Having good electrical conductivity to carry highest specified
load current.
b) Immune to the corrosive action of the soil all along the period.
c) Of sufficient mechanical strength to enable them to be in-
stalled without any damage, and
d) Inert, i.e. must not be a source of galvanic corrosion current,
within the system to be protected.
(iii) The earth electrode must provide as much of the area of
contact as possible with the soil to reduce the resistance of
the current path to earth.
(iv) The resistance of the earth connection must remain within
the allowable specified limit throughout the various seasons
of the year.
All telecom buildings shall be protected against lightning
in accordance with the provisions of IS 2309:1989 as amended
and as per the departmental specifications in this regard.

(2) Fire extinguishers.
(3) Wet risers in buildings more than 15 meters high.
(4) Fire Manual which gives details regarding fire drills and other pre-
cautions to prevent fires.
It is felt that the above measures in themselves are quite comprehensive but
what in generally missing is compliance of instructions given in manual of mainte-
nance of services & on continuous basis.
C. In addition to above, the committee identified one of the major causes
of SPREAD OF FIRE was the insulation of DC power and subscriber cables.
Following four actions to eliminate/minimise the spread of fire/smoke on
account of cables were identified.
(i) Power cables, both A.C. & D.C., intersuit wiring and subscriber cables should
be laid separately, so that short circuiting and fire prone set of cables does
not spread to other cables also. While laying cables it should be ensured
that cables are not laid on sharp edges which can, with the passage of time,
damage the insulation and causes short circuit and also not subjected to
any other mechanical Strain, Engineering instructions should be strength-
ened if required.
(ii) In order to isolate MDF from higher voltages, Engineering instructions should
be examined for further strengthening this area. Importance of regular check
of earthing and lightening protection to be emphaised. Next check due on...
Kind of notice can be maunted in MDF and exchange incharge's room to
draw attention and enforce regular check.
(iii) Barriers should be created at suitable intervals in addition to the require-
ment of normal fire byelaws while laying cables so that fire in one section
does not travel freely along the cables. As per fire byelaws, barriers are
already required at the floor crossings. It is felt that barriers should also be
created along the horizontal runs of the cables. Details of barrier recom-
mended are as per drawing-1.
(iv) The specifications of the insulating material of the cables should be reviewed
and strengthened with an objective to ensure that the burning of the insula-
tion is confined to barest minimum length of the cable and also it generates
minimum smoke.

C. Snggestions for minimising fire
incidences and also losses on this account.
1. Identification of a Fire Warden for each building alongwith a Deputy. He has
to ensure that fire prevention, detection and fighting systems are kept in
proper shape. This is specified in Departmental Fire Manual also. As far as
possible the fire warden shall be provided accommodation in the building
complex.
2. A Display Board which should tell the next due date for fire drill should be
provided at least at two places in the rooms of GM/Dy. DM/DET/Senior Most
Officer. The due date should be painted (i.e. recorded on a permanent basis
and not to be written with chalk). When on the due date, exercise is con-
ducted, the next date can be painted - Ref. drawing-2.
3. Fixing a plate in the MDF room and also in room of senior officer mentioning
the next date for earth and surge lightening protector check. (as per Ref.
drawing-2(2/3).
4. Issuing a perosnal card to each occupant of the building having instructions
regarding steps to be taken in case of fire. (as per Annex-A)
5. Fixing the important fire instructions inside each room. This will ensure reading
of the instructions by the occupants of the building. Fixing these in common
areas is not considered an effective solution.
6. Provision of Fire Barrier as per drawing enclosed at all floor/wall crossings
of all cables laid in exchange.
7. Out of the staff available ensuring human presence round the clock in switch
room for early detection and fire fighting during initial stages of fire.
8. Exploring the possibilities of improving/ strengthening the specifications in
regard to the quality of insulation of D.C. power and telephone cables so as
to further retard the spread of fire and generation of smoke.
9. Providing automatic small independent fire quenching systems at imprtant
fire prone locations in addition to fire extinguishers as per norms.
10. Maintenance of fire delection and fire fighting systems in working through
specialised agencies by entrusting the same to Electrical wing and ensuring
fire drill at regualr intervals and certificate (As per annexure-D).
In addition to the above, aiready existing instructions on fire control particu-
larly in the following areas need to be scrupulously followed.
(i) Observing Engineering instructions with regard to the cable laying particu-
larly in regard to safety from mechanical damage, Earthing continuity at
joints.
(ii) Making additions / alterations in the existing system and use of new gadgets
only after clearance from electrical maintenance unit as well as building
incharge.
(iii) Following the guidelines inclouded in the Fire Manual particularly in regard
to keeping building free from hazardous materials (dry grass, packing cases,
thermocol etc.) and ensuring passages, emergency exits and area around
the building clear of any obstructions.
12. Asking ALTTC to prepare :
(i) A film to highlight the looses on account of fire in Telecom building
and also importance of an individual towards its containment. This
film should form part of fire drill.
(ii) effective slogens for display in building and instructions for perosnal
cards.
(iii) a course module on fire safety in Telecom. Buildings.
13. Making Fire Course compulsary in all the Entry Leval Training courses in
- ALTTC, BRBRAITTC Jabalpur, Regional Training Centres, Circle Telecom
Training Centers and District Telecom Training Centres of the Department.

Precautions/causes against Fire incidents in Telephone Exchanges/buildinds.
Major causes of Fire :1. Short circuit in switching racks.
2. High voltage reaching MDF on account of telephone lines coming in con-tact with high voltage lines and also on account of lightening.
3. Short circuits / loose connection/over loading in DC power cables/sys-tem.
4. Storage of hazardous materials.
5. Indiscriminate additions to existing Electrical wiring without proper tech-nical organization.
6. Improper maintenance of Electrical Safety Devices like Over load relays,Interlocking devices.
Preventive Measures :-
1. Automatic fire detection system and alarm
2. Fire Extingushers.
3. Wet risers in buildings more than 15 meters high.
4. Fire Manual which given details regarding fire drills and other precautionsto prevent fires.
Spread of Fire1. Power cables, both A.C. &D.C., intersuit wiring and subscirber cables should
be laid separately, so that short circuiting and fire prone set of cablesdoes not spread to other cables also. While laying cables does not spreadto other cables are not laid on sharp edges which can with the passage oftime damage the insulation and cause short circuit and also not subject toany other mechanical strain. Engineering instructions should be strength-ened if required.
2. In order to isolate MDF from higher voltages, Engineering instruction shouldbe examined for further strengthening this area. Importance of regularcheck of earthing and lighening protection to be emphasized. Next checkdue on... kind of notice can be mounted in MDF and exchange incharge'sroom to draw attention and enforce regular check.
3. Barriers should be created at suitable intervals in addition to the require-ment of normal fire byelaws while laying cables so that fire in one sectiondoes not travel freely along the cables. As per fire byelaws barriers arealready required at the floor crossings. It is felt that barriers should alsobe created along the horizontal runs of the cables. Details of barrier rec-ommended are as per drawing-I.
4. The specifications of the insulating material of the cables should be re-viewed and strengthened with an objective to ensure that the burning ofthe insulation is confined to barest minimum length of the cable and alsoit generates minimum smoke.

Dear Shri
It is observed that there has been a spurt in fire incidents in the recent past.Some of them have caused extensive damage to the telecom equipments anddisrupted the telecommunication services. One such incident took place at Cir-cus Telephone Exchange at Kolkata. The entire transmission room was burnt,most of the long distance modems redued to ashes, service from the main ex-change and associated RSUs and DLCs to around 64,000 telephone customers,12000 broadband customers and 3,000 leased line customers were interrupted.It caused a huge financial loss and also adversely affected the goodwill of BSNL.
2. An analysis of various fire incidents that took place in the past reveals thatthe following are found to be the main reasons for fire incidents :
i) Fire starting from window air conditioners;ii) External surge of voltage passing through to exchanges equipments;iii) Overloading of electrical wires and short circuits in electrical installa-
tions;iv) Inadequate protective devices in the eletrical installations.
Many of these fires could have been prevented/ contained and the damagescaused reduced if appropriate precautions had been taken as conveyed by thisoffice from time to time and contained in the Fire Protection Manual issued byT&D Circle (copy already sent)
To prevent occurrence of fire and contain its spread, I would like you to takethe following steps immediately :
Constitute special teams to carry out the inspection of all the vital buildingshousing exchanges and transmission equuipment to check whether the mea-sures taken are appropriate. The team should make special checks on the follow-ing immediately.
(i) Check that all the window air conditions are properly functions and arebeing maintained properly, they do not draw excessive current and thetemperature is maintained in the switch room at an appropriate level.Such air conditioners are not supposed to run continuously. Theswitchover arrangement. should be operational. The air conditioners areto be serviced regularly as per schedule and AMC is properly main-tained/ implemented.

(ii) Circuit breakers, HRC and other fuses wherever they exist are of speci-fied/matching capacity, which would give proper protection to the equip-ments and the electrical wirings. None of these protective devices is tobe by-passed by copper wires etc. Electric wiring should not be over-loaded beyond its capacity. Insulation should be proper and earth wiresshould be properly provided and used.
(iii) Protective devices in MDF (IPM etc.) are fully provided.(iv) Fire alarm system functions properly. All the fire detection points are
tested to sense the fire within a prescribed time and give alarm.(v) It has been noticed that in some of the fire cases, the keys of the trans-
mission room are sometimes not avalable. Keys of all the equipmentrooms which are kept locked at night should be available in the securityroom.
(vi) Inflammable material/store are not kept in the telephone exchange build-ings.
(vii) Fire extingushers are sufficiently provided and that they are refilled fromtime to time before their expiry date.
(viii) There should be free access in buildings to the fire personnel to controlthe fire, adequate passage should be made available for movement ofFire Brigade and their personal. Availability of sufficient water (watertank) etc. for firefighting is to be ensured.
(ix) The local fire authorities should be contacted to ensure that they areproperly equipped to reach the higher floors of our multistoried build-ings.
(x) The instructions of MS Cell and those contained in T&D Circle's FireProtection Manual are fully followed.
3. The inspection of all the electrical and other installations as mentioned abovemust be completed within one month and a confirmation be sent to me that all thecorrective actions have been taken. A few exchange buildings may please beinspected personally at your level to ensure that appropriate actions have beentaken and there is no slackness in this regard.
4. I would further like you to go through the reports for fire incidents which hadoccurred in your Circle during the last two years and see why they were notprevented/ contained. Also if there were any lapses on the part of the officer/staff,the responsibility must be fixed and suitable action taken against the erring of-ficer/staff. Please send me a special report on it within a month.
With best wishes.Yours sincerely,

Some of them have caused extensive damage tothe telecom equipments and disrupted the telecommunication services. T & D Circleis the nodal unit to carry out investigations for all fire incidents and also to suggestcorrective actions in time. There has generally been a long delay in submission ofthe reports. Hance it is requested that the final inspection reports on fire incidentsmay be submitted within a month of occurrence of fire.
The fire protection manual were issued by T&D Circle(presently Inspection Circle)in 1985 and the same needs to be revised/updated keeping in view the findings ofvarious investigation reports of fire incidents that have occurred in current andprevious years. Copy of the various instructions issued from this office to field unitsare attached for your reference. The updated fire protection manual may be recir-culated in the field units.
Also during Inspection Circle's inspection of the exchanges, special emphasis onfire detection, fire protection mechanism, fire protection devices as well as electri-cal/short circuit devices and protection at MDF may be given. The inspecion reportshould contain specific observations/recommendations in this regard.
I would like to bestow your personal attection on the matter and submit compli-ance.
With regards.
Yours sincerely,
R.K. Sharma

H 1. The split A/C units and Window A/C units should be avoided in major telecom
nodes as these lead to major fire hazards. Only package type A/C plant should be
provided for such nodes.
2. If it is unavoidable to provide Split/Window type A/C units, following preventive
steps should be taken:
i) Comprehensive maintenance of the A/C units to be done, consisting of four
to six routine visits in a year for a systematic checkup and overhauling of
units if required. The electrical wing should keep the maintenance log of all
A/C units of the site and it is to be countersigned quarterly by DE in-charge
of the Telecom node for verification.
ii) In major telecom nodes, Programmable Logic control panel should be pro-
vided and properly maintained for rooms having multiple A/C units. This should
work on auto mode.
iii) In case where change over of A/C units is done manually, a register is to be
maintained to log the change-overs. SDE(Electrical) shall be responsible
carry out the same. It is to be ensured that no A/C unit is operated for pro-
longed period which may cause overheating.
iv) The heating load capacity of the telecom installations vis-à-vis the cooling
capacity of the A/C units installed in a room should be regularly assessed by
DE In-charge. If required, additional A/C units, should be provided immedi-
ately.
v) To overcome effects of voltage fluctuation, voltage stabilizers for A/C units
may be provided.
3. Periodical check and maintenance of fire alarm system and fire fighting system
in Telephone exchanges and Transmission centres should be done.
4. All Telephone Exchange building should have fire escape route. This is very
essential for safety of the people present in the building during fire.
5. Regular check of earth as per DOT/BSNL guideline issued from time to time.(Vide
Latest BSNL order no.36-3/2004/PHM dated 21.07.2004)
6. Preventive measures to be adopted to avoid fire incidents in Telephone Exchanges/
Buildings(as per BSNL order no. 19-30/98-PHM dated 11.09.2001)
7. Log book should be maintained in Battery & Power Plant Room, E/A room, A/C
plant etc, properly.
8. Manual Power shut down, if necessary in emergency cases, must be noted in the
log book with start time & restoration time.
9. Fire Brigade can be requested to use suitable material instead of water in case of
Fire in Telephone Exchanges. It is suggested that the matter may be explored after
consultation with both senior officers of Calcutta Telephones and the Fire Brigade
authority, which type of material will be suitable to extinguish the fire caused by the
electronic equipments, foam was used for oil, varnish & paints, CO2 was used for
the fire caused by Electrical equipments, water was used to extinguish the fire
caused by the furniture, paper etc & dry power was used for all type of fire. Nowa-
days probably Halon is not used due to environment pollution. (as suggested by the
Scientists).
