Fire In High Rise Buildings
Analysis Based OnReal Problem Situation
This work describes an important aspect within the field of safety in residential area namely fire safety. This paper presents 3 case studies on fire based accidents in high rise buildings. Under these case studies important aspects such as cause, immediate response, emergency preparedness planning, loss in terms of life and property as well as prevention and control measures have been discussed. This paper also focuses on the actual causes of majority of fire related accidents in residential areas mainly student hostels. Special emphasis has been put on at risk behavior/ unsafe behavior leading to these catastrophic accidents. Majority of accidents are result of unsafe acts rather than unsafe conditions thus BBS plays an important role in preventing accidents and bringing risk to an acceptable level by means of spreading awareness. Apart from it, this paper also highlights the different types of residential fires, their prevention and control measures focusing on use of different chemical extinguishers for different types of fire, different types of smoke detectors, fire alarms, role of sprinkler system and emergency exit plan. This paper also presents a full fledged emergency planning and response plan for a local student hostel primarily focusing on duration of mock drills, training of hostel staff, provision of proper fire fighting equipment in the hostel premises and their compliance with the appropriate standards.
Fire disasters are one of the most common and catastrophic disasters in the world today. This study aims at analyzing residential fires in high rise buildings. High rise buildings pose high risk of fire because of it’s configuration into widely varying specifications leading to a diverse building environment with many variables which make the hazards difficult to identify and control. Requirement for fire prevention and control in high rise building is inevitable because of higher occupancy and longer distance to exit discharge which may lead to more casualties and property loss.
Urban economy is developing rapidly, as a result, land resources are becoming scarse every year and high rise buildings are gaining a great deal of importance. The design of these high rise buildings is very complex thus calling for an urgent need of developing ways to handle fire safety situation and it has become a major issue for the society.
Some of the major fires in high rise buildings in the recent years are as follows
1) 26 Jan 2018, A hospital in fire in Miryang, South Korea killed atleast 37 people and injured more than 131 others.
2) 28 Dec 2017, Kamala Mills fire in Mumbai killed 14 people.
3) 28 Dec 2017, Apartment buildings caught fire on Prospect Avenue in the Bronx in Newyorkcity killed 12
4) 26 April 2016, A fire broke out on the top floor of National Museumof Natural History in NewDelhi, no casualties were reported.
5) 2015, Afire in a residential building in Baku, Azerbaijan kills 14 people.
Fire risk analysis of high rise building is important because these buildings still lack an efficient fire extinguish method for safe evacuation and if safe evacuation system is in place then many a times occupants of the buildings are not properly trained on how to respond in case of emergencies. Many a times the location of the building also plays a huge role as proper connecting roads might not be available making it difficult for firefighting vehicles to reach on time. Building codes and regulations prescribe basic requirements for assuring fire and life safety in buildings. For implementing these codes and regulations it is required that a fire protection engineer is consulted since the design and construction stage of the building so as to develop a proactive approach towards firefighting, but in reality a reactive approach is followed for fire fighting in high rise buildings, thus there is no proper compliance with legal requirements.
1. 28 Dec 2017, Kamala Mills fire in Mumbai
A noteworthy fire softened out up a bar in the Kamala Mills compound in Mumbai on Dec 28, 2017, early morning.The burst was accounted for around 12.30 a.m. from a bistro The Mojo, a housetop eatery bar in The Kamla Trade House and rapidly spread to another encompassing bar and an eatery, said an authority of BMC Disaster Control.More than 12 fire tenders were raced to battle the burst which was brought under control around 6.30 a.m.While most of the casualties are accounted for to have died on the recognize, the fire fighters could protect 10 others securely from the jumping flares.

3. 26 April 2016, A fire broke out on the top floor of National Museumof Natural History in New Delhi
An enormous fire developed in the National Museum of Natural History post midnight on Tuesday 26th April 2016. It took fire benefits more than four hours to splash the blast with 35 fire motors squeezed into benefit. No losses were accounted for. Extensive crest of smoke exuding from the best floor of the FICCI building where the historical center is housed, gotten the security work force’s attention at around 1:45 am. A call was made to the fire administrations and a couple of motors were hurried in from the Connaught Place fire station. Nobody was in the working at the season of flame as the historical center was shut around then. As the fire spread to the lower floors, more fire motors were hurried in. It took the following three and a half hours to bring the fire under control and an additional three hours of chilling off operations.The fire started on the best floor and spread to four stories underneath. 6 autos with water driven stages to drench the fire in the best floors were utilized. Other 30 groups were battling the blazes from inside the building insides.

CAUSES OF FIRE IN HIGH RISE BUILDINGS
1.The increased use of high strength concrete (HSC) in buildings causes spalling of concrete at elevated temperatures and results in reduction of fire resistance.
2. Factors such as building structure strength and material, fire load characteristic and distribute, the formation and strength of ignition source, fire alarm system, fire equipment, emergency countermeasures also play an important role in the cause of fire.
FIRE PROTECTION IN HIGH RISE BUILDINGS
NFPA 101®, Life Safety Code has provisions for existing as well as new high-rise buildings. NFPA 101®, Life Safety Code, 2012 edition, section 11.8 contains requirements potentially applicable to a high-rise building. The chapter for a specific occupancy decides whether all or a few of the section 11.8 requirements are required for occupancy and decides if the requirements are for new or existing constructed dwellings. Amid section 11.8 needs are an approved supervised automatic sprinkler system; a Class I standpipe system; a fire alarm system alongside an accepted emergency voice/alarm communication system; two-way telephone service for fire department use; emergency lighting; standby power; and an emergency command center. Existing high-rise hotels should be protected throughout by an approved directed automatic sprinkler system. Existing high-rise health care occupancies must be Type I (442 or 332) or Type II (222) construction (as must existing health care occupancies 4-6 floors in height). As per NFPA ,construction of buildings can be categorized into various types. This corresponds to the “fire resistive” construction type category previously used in NFIRS as well as a subpart of the “protected noncombustible” category. A provision added to the code in 2009 and modified in the 2012 edition requires existing high-rise hospitals should be guarded with automatic sprinklers within a nine-year period. Since 2006, the code requires all nursing homes, disregarding of height, to be protected with automatic sprinklers. The defined construction types can be briefly summarized by these major characteristics:
- Fire resistive – Concrete or fire-resistant-covered steel construction rated for 2 hours;
- Heavy timber – Construction where any exposed wood load-bearing members has no dimension less than 2 inches;
- Protected non-combustible – Concrete or fire-resistant-covered steel construction rated for 1 hours;
- Unprotected non-combustible – Exposed steel construction without fire-resistant covering;
- Protected ordinary – Masonry load-bearing walls with columns, wood floors, and roof decks all protected by fire-resistive coating rated for 1 hour;
- Unprotected ordinary – Masonry load-bearing walls with exposed columns, wood floors, and roof decks without fire-resistive coating;
- Protected wood frame – Wood frame construction with wall and ceiling surfaces protected by fire-resistive covering, such as gypsum board;
- Unprotected wood frame – Wood frame construction without fire-resistive covering.
High-Rise Building Fires, 9/13 18 NFPA Fire Analysis ; Research, Quincy, MA Existing high-rise apartment buildings should have an approved directed automatic sprinkler system, installed throughout, with two exceptions. One is if every living unit has exterior exit access in accordance with section 7.5.3; and the another one is whether the building has an “approved, engineered life safety system” in accordance with section 18.104.22.168.4. The latter exception for an engineered life safety system is also the only barring to the requirement for a complete, approved, supervised automatic sprinkler system in existing high-rise office buildings. NFPA 1®, Fire Code, requires sprinkler retrofitting in all high-rise buildings. Since 1999, NFIRS (the national fire incident data base) has included an option to report fires as confined fires, in which case very little detail is required. This change encourages the reporting of very small fires, but introduces a high degree of uncertainty in the analysis of detailed characteristics of those fires
CONTROL MEASURES FOR FIRE IN HIGH RISE BUILDINGS
1. Emergency rescue in high rise buildings
The paper put the “security and anticipation first” as the rule and investigations the highlights of elevated structures fire to pick up the course of mishap by seeing tall structures and its fire and accomplish an incomplete occasion tree whose best occasion is the immediate fire peril misfortune, while it joined with the present condition of the economy. In perspective of the elevated structures fire issue, this is a “worldwide” issue, and a few focuses are advanced as followings: (1) Putting forward another thought that is from “man-machine (content, gear, and so on.) – condition”, that is, the two parts of the innovation (equipment) and administration (programming) ought to be contemplate exhaustively to take care of issues in tall structures fire avoidance. (2) Technology can’t take care of the issue that fire control offices can’t stay aware of the expanding of the floor stature adequately in a here and now. As far as the present monetary circumstance in our nation, a tall structures fire anticipation security framework which takes the administration as diagram ought to be advanced while innovation is a strategy and outstand the controlling and coordination that that administration exhibits on innovation. (3) Our tall structures ought to underline the four elevated structures fire wellbeing countermeasures with the acknowledgment of flame aversion security framework in the meantime, and accomplish innovation and the administration synchronous improvement as quickly as time permits. In addition, tall structure fire counteractive action security framework ought to be culminated. With a specific end goal to unravel the tall structure fire counteractive action wellbeing issue, this examination plans to give some viable incentive to the outline of elevated structure, appraisal of flame security and foundation of prudent crisis program.
