DISASTER MANAGEMENT PLAN

INTRODUCTION

Godrej Vikhroli Properties LLP, a part of the Godrej Industries Ltd., is proposing a

residential and commercial development including office buildings (including the existing

Godrej One building) and a hotel building on land bearing CTS nos. 51(part), 52, 52/1 to 17

of Village Vikhroli, Vikhroli (East) Mumbai. The proposed development will consist of

construction of one IT building with G+11 floors and one basement.

Total Plot Area : 1,38,402 sq.m

FSI Area : 239,281.3 sq.m.

Non FSI Area : 185,993.70 sq.m.

Height : 59.82 m

The proposed number of tenements is 861 and shops is 34. Occupancy is about 27,550 of

which residential users are 4,620, commercial users are 19,138 and retail users are about

2,917. Hotels users are approx. 875.

The proposed project site lies in the N-ward of suburban Mumbai. At present, the land is not

vacant. The existing structures will be demolished before new construction.

An emergency situation in a residential cum commercial complex may be due to manmade

hazards like fire, power outage etc. or due to natural disasters viz. earthquake, flooding etc.

For the preparedness of on-site emergency, the following objectives are taken into

consideration

The objective of a Disaster Management Plan is to ensure effective mitigation plan and best

possible protection of the members of the society during a disaster occurrence.

A hazard is defined as a dangerous condition or events that threaten or have the potential for

causing injury to life or damage to property or the environment is called hazard. Hazards can

be categorized in various ways, but based on the origin, they worldwide are basically grouped

in two broad headings:-

1. Natural Hazards (hazards with meteorological, geological or even biological origin)

2. Unnatural Hazards (hazards with human-caused or technological origin)

Disaster

A disaster is the product of a hazard such as earthquake, flood or windstorm coinciding with

a vulnerable situation, which might include communities, cities or villages. There are two

main components in this definition: hazard and vulnerability. Without vulnerability or hazard

there is no disaster. A disaster occurs when hazards and vulnerability meet.

Importance of Multi-hazard Management Plan

It is apparent that Hazard identification and Risk assessment is done to handle natural

disasters such as floods, cyclones, landslides etc. Also, it cannot ignore man-made disasters.

This Disaster Management Plan is designed as per the present need and the major strategies

to respond to any unexpected situation have also been considered. In the multi-hazard

mitigation plan, all the disasters will be handled properly following the given procedure.

The main features of the Disaster Management Plan are:

2

• It gives importance to all the disasters equally and helps to mitigate the situation

beforehand.

• All the line authorities are assigned with their proper role and responsibilities, which are

clearly indicated in this plan.

1. RISK ASSESSMENT AND VULNERABILITY ANALYSIS

1.1. Classification of Disaster

Disaster can occur at any point of time. It is essential to consider the mitigation plan and

protection for all the society members during occurrence of a disaster. If the society i.e. the

tenants/ residents of the buildings are aware of the actions to be taken during a disaster, then

the effect of disaster can be reduced or avoided.

Following types of natural disaster can occur with a prior indication or without any prior

indication.

Natural Disasters: Natural Disasters occur naturally with or without any prior indication.

a. Earthquake

Earthquakes are usually caused when rock underground suddenly breaks along a fault. This

sudden release of energy causes the seismic waves that make the ground shake. Building

develops cracks, collapses when the intensity of earthquake is more and prolonged.

Probability of Occurrence: As per the earthquake zonation of India, the proposed site falls

under seismic zone III which is referred as moderate risk zone. Thus the possibility and

severity of the experiencing the earthquake apparently decreases. Although there are no past

records of this disaster in this region, earthquake of intensity between 5.0 and 6.9 on the

Richter scale can occur in Zone III. Accordingly the measures proposed are enumerated in

the section of mitigation and preparedness.

b. Cloud Burst and flood due to heavy rainfall

A cloudburst is an extreme amount of precipitation, sometimes with hail and thunder, which

normally lasts no longer than a few minutes but is capable of creating flood conditions.

Sudden cloudburst can cause a flood to occur. This is one of the natural disasters. During the

thunderstorms, the air mass that goes up from the lower level carries a certain amount of

water in it. Sometimes that air current abruptly stops moving and the water mass falls down

forcefully on the surface of earth. This natural phenomenon is known as cloudburst.

Flooding may occur due to the following reasons

• If the rainwater does get the access to the natural stream or municipal drains

• Delay in water flow from all runoff towards the natural stream like river, nalla (or sea).

• Slow discharge of water

• Flow diversion

• Chocked up drains, nallah, river bed.

The proposed site does not fall in any flood prone areas. Even if heavy rain fall are received,

a well designed storm water drain is proposed as also there is a municipal storm water drain

of adequate capacity.

c. Wind Pressures

Site specific wind speed plays a key role in the determination of wind-induced response of

structures. Numerical simulation studies for this project by means of CFD (Computational

3

Fluid Dynamics) were used for predicting the behaviour of wind in and around the proposed

buildings. This analysis was carried out with applications involving fluid structure

interaction. CFD technique was used for determination of wind effects on surrounding due to

the high rise building. The wind speed and its direction were procured from MPCB and they

were used for stimulation using CFD modeling.

After the construction of proposed high rises, reflection and deflection of wind will take place

at the proposed location. Due to this, inversion of air will be observed at different zones. As

per the simulated findings, the inversion zone would have wind speed of about 0.16 – 0.88

m/s. Inversion zone mostly would fall to a distance of 15 – 18m from the building line.

d. Lightning Strike

Lightning can score a direct hit on a highrise building. It can strike the overhead power line

which enters the building, or a main power line that is blocks away. Lightning can strike

branch circuitry wiring in the walls of the building.

Lightning can strike an object nearby, such as a tree or the ground itself and cause a

surge. Voltage surges can be created by cloud to cloud lightning. A highly charged cloud

which passes overhead can also induce a voltage surge.

Buildings are protected from lightning by metallic lightning rods extending to the ground

from a point above the highest part of the roof. A lightning arrester is a device used on

electrical power systems and telecommunications systems to protect the insulation and

conductors of the system from the damaging effects of lightning. The typical lightning

arrester has a high-voltage terminal and a ground terminal. The conductor has a pointed edge

on one side and the other side is connected to a long thick copper strip which runs down the

building. The lower end of the strip is properly earthed. When lightning strikes it hits the rod

and current flows down through the copper strip. These rods form a low-resistance path for

the lightning discharge and prevent it from travelling through the structure itself.

Unnatural Disasters: These kinds of disasters generally occur due to human error or

negligence.

e. Fire

Fire is a hazard which is caused mainly due to human negligence. There are other reasons

like electrical short circuit, rain water seepage in electrical installations, gas cylinder

malfunctioning, domestic gas leakage which can cause fire disaster in a residential building.

A full proof fire fighting system is designed for the buildings which meets all fire safety

norms and has a mitigation plan to tackle the fire hazard.

During construction all safety precautions will be taken to handle the fire hazard. During

construction fire can break out due to following reasons:

• Electrical loose connection

• Electrical short circuit

• Storage of Inflammable material like diesel, paint at site

• From cooking gas cylinders at labour hutment

Post Occupancy:

The proposed project is designed with utmost care for all fire safety norms for its residents

and the building as a whole. The normal cause of fire in the proposed project post-occupancy

is LPG cylinders, loose connection to LPG cylinders, electrical short circuit, loose plug tops

used by residents, storage of highly inflammable material like diesel, kerosene by residents,

4

fire crackers in festival session etc. The building will be constructed with all fire safety norms

to mitigate such calamities during operation phase of the building. Fire proof material will be

used as per design for various components of the building. Electrical cables and switches will

be IS (Bureau of Indian Standard) certified and will have the minimum fire rating to mitigate

any fire hazard. The cabling and jointing will be done by professional agencies to avoid any

mistake while installation.

f. Building collapse

To protect against building collapse, hardening of the buildings structural systems may be

required. Designers should balance the hardening of the building envelope so that the

columns, walls, windows and glazing have an approximately equal response for damage/

injury. This is a multi disciplinary effort of the architect, structural engineer, mechanical

engineer and other design team members in order to achieve a balance building envelope.

g. Vehicle Accidents

Traffic flow to and within the site needs to be maintained so that there are no obstructions to

existing traffic flow on access roads. Also, road side parking will be avoided. The entry/ exit

to the site will be with adequate curvature at kerbs so that vehicles coming out/ entering the

building do not impinge on road traffic directly. Regular maintenance and upkeep of the

internal roads within project site will ensure smooth traffic flow

h. Security breach

Included in this category are Bomb Threat, riots & vandalism: Bomb threats could be genuine

or false and many a time they turn out to a hoax. Unscrupulous elements with the intention of

creating a panic tend to resort to such hoax calls. Confirmed militants however resort to such

deeds with the intention of destruction and strike terror. It would therefore be prudent to

assess the genuinity of bomb threats. The threats are usually through phone calls, giving very

little time to react or through mail, giving a certain date of an explosion that could occur. It is

very rare that the caller will identify himself and the message sent through any messenger for

fear of easy identification.

i. Malfunctioning of Lifts

Regular maintenance of lifts and other BMS has to be conducted. There should be a specific

Committee appointed for maintaining the systems during the operation phase.

Off-site Hazards

Following are some other types of hazards that may be of concern to the proposed

development for which effective mitigative measures need to be in place:

j. Rail/Air Accidents

k. Nuclear radiation hazards

l. Traffic accidents along the main road artery

m. Biological & Chemical hazard

n. Violence outside the project site

If you are a trained first aider, wear the visibility badges and

be prepared to attend to causalities.

The emergency controller and the incident controller will

have the security supervisor / guards to assist them to fight

the fire. In addition, the emergency controller will call the

Mumbai Fire Brigade and other help if the emergency is of

graze nature.

Emergency Mitigation Procedures : Evacuation

Safety warden to guide evacuation in an orderly manner

On hearing the siren in other wings the wing safety warden

will guide the occupants for evacuation by following the glow

signage exit routes, as per the guidance given by Incident

controller. Follow fire escape route only.

The emergency exit door and emergency exit route have been

clearly marked with a glow sign

Do not use lift and normal staircase

Do not try to carry any of your belongings along with you

Do care for your visitor’s, take them with you

8

Always use the handrails on stairs and do not attempt to pass

others on the stairway.

In case fire is near fire escape / staircase or in the passage,

floor warden will guide the occupants on to the proper route

for evacuation.

Following measures will be taken during construction to avoid fire hazard:

• Training of workers on fire hazards during construction

• Tool box talk to workers on fire hazard and dos and don’ts

• Constant check on electrical connections

• No loose connection

• All plugs should have plug-tops

• ELCBs for all circuits

• Fire extinguishers at site at various location

• Regular check on cooking facilities at labour hutment by project manager

• Separate storage for highly inflammable material like diesel, paint.

Following measures will be taken during operation phase to avoid fire hazard:

To protect the building and the residents from any fire hazard building will be equipped

with any one or combination of following installations.

• Fire Hydrants

• Wet riser

• Primary fire fighting line

• Secondary fire fighting line wherever false ceiling is provided.

• Fire detection and alarm system

• Central fire store

• Separate water tanks of required capacity for fire fighting

• Easy access to fire engine during any fire hazard inside the building premises

• Automatic sprinklers system while smoke is detected (if required).

Number of staircases in buildings and number of fire escape staircases/ lifts –two

staircases and two lifts per building has been provided. One staircase out of the two is a

fire escape staircase. One lift in each core will be provided which will be a fire cum

stretcher lift with a fire man’s switch.

9

As the site is located in the well developed Mumbai city, the problem of power outage is

not experienced. Even though the condition occurs, a sufficient back up for DG sets will

be proposed. Disaster due to fire struck may occur for which the mitigation measures are

given in subsequent section.

Emergency Mitigation Procedure : Natural Calamities : EARTHQUAKE

What to do DURING an earthquake?

Drop, Cover, and Hold On! If you are not near a desk or

table, drop to the floor against the interior wall and protect

your head and neck with your arms. Avoid exterior walls,

windows, hanging objects, mirrors, tall furniture, large

appliances, and kitchen cabinets with heavy objects or glass.

Do NOT run outside!

Stop driving if you're in a safe place, and if outside, go into

an open area. Don't attempt to go outside if you're not in a

position to do so--you could be injured by falling debris.

When the earthquake is over, be sure to wear shoes to avoid

broken glass. If you smell gas, turn off the main gas line and

get out of the building. And don't forget--aftershocks do

occur, so don't assume the damage is done after the main

shock has ended

EVACUATION Emergency controller, incident controller and nominated fire safety wardens would play a

similar role as that in case of fire. Immediate evacuation of the building will be absolutely

necessary in major emergencies.

During earthquake following measures should be taken:

• At first few seconds residents should stay calm and open doors for easy access

• After the tremor subsides, Managing Committee shall instruct the residents for safe

evacuation of the building

• Building Lift should not be used and main power supply should be shut

• Intimate the external authorities like Fire Brigade for rescue operation

• Residents who are safe should be moved out of the building to a safer relief location

• If people are buried in debris, relief agencies should be called for safe rescue of the

people

• Arrange for relief and rehabilitation space

• Arrange for medical assistance, food.

• Residents should not drive during earthquake

• Residents should not move closer to any electrical pole or line while evacuation

process

10

Measures to be taken during Flood/ Cloudburst

• Managing committee should arrange for safe evacuation of the residents

• Intimate the external authorities as mentioned in this plan

• Managing committee, Building Manager, Security personnel should guide the way

towards safe evacuation of the building.

• Arrange for relief and rehabilitation space

• Arrange for medical assistance, food.

• Residents should not drive during flood

• Residents should not move closer to any electrical pole or line while evacuation

process

• Switch off the main power supply of the building

SOCIAL CALAMITIES :

The following preparedness is recommended to handle bomb

threats :

• Try to identify the caller and take as much information as

possible

• Inform emergency controller to call police and get their

guidance for further action. The local police station to be

intimated immediately on receipt of such calls. The police is

trained to handle such threats and have access to special bomb

detection and disposal squads.

• Human life is most important and on receipt of such threats,

emergency controller will take a call to evacuate the site with

the employees assembling at the site emergency assembly

point. All employees will be clearly informed about the

threats and panic will be minimized.

• Follow the evacuation instruction given by wing safety

warden on public address system.

OTHER EMERGENCIES : GAS LEAK

11

Do’s & don’t in case of gas leak :

• If you smell gas, DO not smoke or strike matches or use

mobile phone

• Do not turn electrical switches on or off.

• Do open doors & windows.

• Do keep people away from the affected areas.

• Do close burner and regulator knobs

• If there is a leak from the cylinder, remove the cylinder to a

safer place and call for help from the nearest authorized

dealer.

• Immediately inform the wing warden and follow his

instructions.

• Follow the evacuations given by the wing warden or IC

• Evacuate the building at the earliest

• Emergency controller to inform fire brigade, gas agency for

further guidance and action.

• Return to the building when normalcy is restored by EC and

instructed to do so.

5. Onset of Disaster

5.1. Actions to be taken during Disaster

Action to be taken during disaster depends on nature of disaster i.e. where prior indication of

disaster occurrence is there and where there is no prior indication and disaster happens all of

a sudden.

First Response Procedure (F.R.P)

Chairman, Managing committee members, Building Manager, Security staff will have to be

quickly responsive to the disaster. It’s important to keep cool and patience during the disaster.

No panic should be created and relief members should understand the gravity and importance

of the situation and guide the residents to a safer place and provide relief.

It is important that Chairman or designated Managing Committee Member intimates all the

external agencies at once about the disaster. Apart from external authorities, internal

authorities like Chairman, Managing committee members, Building Manager, Security staff

should be aware of the situation and relief measures to be taken.

On occurrence of a disaster, the Site Disaster Manager will take the following actions:

• Intimating and give guidance over public address system to the residences about the

disaster.

• Prepare an instant mitigation plan and intimate all concerned.

• Network with State, district and ward level control rooms

• Ensure adequate warning before switching off power

• Guide the residents on safe evacuation process.

• Evacuate the residents to a safer place.

• Assure occupants of continuous communication and take all measures to keep up their

morale.

• Guide occupants on the steps being taken for evacuation in a systematic manner.

• Take steps to Reduce/eliminate panic.

• Liaise with Law & Order machinery

• Intimate all external agencies like Police, Hospital, and Fire Brigade, NGOs about the

likelihood of occurrence and evacuation plan and seek help.

When prior indication is not there and disaster happens all of a sudden following actions will

be taken. At this situation only relief and rehabilitation will have to be done as soon as

possible.

• Take relief measures

• Provide medical help

15

• Provide safe access to rehabilitation camp

• Provide food and drinking water

• Intimate all external agencies like Police, Hospital, and Fire Brigade, NGOs about the

evacuation plan well in advance.

6. Preventive Measures
