Risk Assessment & DMP for Proposed Expansion of Residential Development Sahajanand hitech construction pvt. ltd. Page 1 RISK ASSESSMENT & DMP Risk assessment study deals with identifying and evaluating the magnitude of impending risks to which the neighbouring population is exposed due to occurrence of accidents from project construction and development. This assists in illustrating the guidelines for preparation of disaster management plan which will be executed to handle the situation if any emergency. Following are the risks that are identified in buildings. 7.1 FIRE RISK Fire is mainly caused in residential complex due to negligence, short circuits and malfunctioning of gas regulator, tube and such related products. At the proposed project, hazard occurrence may result in on‐site implications like: Fire and/or explosion; Leakage of flammable material and leading to fire; Natural calamities like earthquake etc. There are two worst‐case scenarios for fires in buildings: If fire takes place at lower floors with high intensity such that even after it is being extinguished, it could damage the building structure on term point of view. A fire originating on the building’s lower floors is able to spread throughout all the levels of the structure. In spite of the clear gravity of the above scenarios, these types of fire have happened rarely in tall buildings. More typically, fires in tall buildings yield only partial structural damage. However, losses of life and property can still be substantial. Emergency prevention through good design, operation, maintenance and inspection are essential to reduce the probability of occurrence and consequential effect of such eventualities. However, it is not possible to totally eliminate such eventualities and random failures of equipment or human errors, omissions and unsafe acts cannot be ruled out. An essential part of major hazard control has therefore, to be concerned with mitigating the effects of such emergency and restoration to normalcy at the earliest. The overall objective of a disaster management plan is to make use of the combined resources at the site and outside services to achieve the following: 1. To localize the emergency and if possible eliminate it; 2. To minimize the effects of the accident or hazard on people and property; 3. Effect the rescue and medical treatment of casualties;

7.2PUBLICSAFETY
The incidenceof fireor otherdisasters occurring inbuildingsoften endangersthesafetyofthepersonsworkinginthestructure,intheeventofanemergency.People present in such structures often do not know proper emergencyprocedures,aggravatingfireand/orcausinginjuryanddeath.
Theonlywayofreducingthedamagetopubliclifeandpropertyisbyconductingfire safety drills and installing well equipped fire safety equipment’s such assmokedetectors,heatsensors,sprinklers,hosereel,firepanelsandfirealarms.Thepeopleworkinginbuildingshouldbemadewellconversantwithemergencyprocedures, such as closing doors when fleeing a fire, as well as staying inapartments,ratherthanattemptingtoescape.
It is recommended that mock‐drills should be carried out at least once in sixmonths.
7.3TERRORISM
Very tall buildings, which often serve as corporate, municipal, or nationalsymbols; they become the targets for terrorist attack. Appropriate securitymeasureswouldbe taken inandaround toensure limitedaccess tokeyareas,such as attached parking garageswhere bombs can be easily placed. Buildingmanagement would carry out surprise checks. The building management willhavetherecordofallthevisitorsinthebuilding.
Personnel without any specific duties should assemble at the nominatedplace.
All vehicles except those that are required for emergency use should bemovedawayfromtheoperatingareainanorderlymanneratprenominatedroute.
Electrical system except the lighting and fire fighting system would beisolatedandbekeptseparateintheproposedbuilding.
If the feed to the fire cannot be cut off, the fire must be controlled and notextinguished.Someofthemeasuresthatcouldbefollowedare:
