1. Introduction
Fire accident in building is major threatening for developing country. Developed countries have less building fire risk respect to building of developing countries. In Developed Country, Fire Safety rules, regulation, guidelines and codes is strictly enforced, therefore building owner ensure all Fire Safety related compliance, during building design, construction and later to control building fire risk. India is developing country and here are major threaten of fire accident in building. Fire accident results huge losses of lives and property damage. In India, each year fire accident occurs in several building due to negligence and not follow safety rules of building owner or occupant people. Risk, related to fire accident depends on nature of building (such as Commercial building, multistoried building, Hospital, shopping mall, Factory warehouse), existing fire detection & fire fighting system, material used in building and fire safety awareness among occupants of building.
According to NCRB, India in year 2015 total of 18,450 cases of fire accidents were reported in which 17700 people were killed and 1,193 injured. 42.1% deaths were occured in residential building due to fire accidents. Such Fire accident occurred in different state of India and majority of fire accident occurred in Maharashtra that was 22% of Total fire accident of India.
As per The National Crime Records Bureau Data, Total 113961 People lost their lives due to fire accident during 2010 to 2014. Major death occurred in Maharashtra state and it is approx. 24293. During 2010-14, percentage of women victims are more than man, the number of women victims was 75039 or 65.8% of all the deaths. The number of male victims on the other hand was 38917 or 34.2% of all the deaths. In year 2014, Fire accident reported was 26025 and in year, 2014 it was reported 19513 there this data shows percentage of accident decrease. The temple fire in Kollam that claimed more than 100 lives has renewed focus on fire accidents. The data available with the National Crime Records Bureau (NCRB) indicates that fire accidents of all types caused more than 1.13 lakh deaths from 2010 to 2014, at a staggering average of 62 deaths per day. Fig. (2), Shows Total numbers of Fire Accident and death during 2010 to 2014.
As per NRCB, Electric short circuit, by fireworks, Gas cylinder and stove bursting are major cause of fire accident and apart from this smoking, use of heater etc. are cause of fire accident. Maharashtra is first state where fire accident occurred more respect to other state of India. Few Indian states name are given in figure (3) that shows total No. of fire accident occurred during 2010-2014 in different state.
2. Causes of Fire Accident in Building
In building, there may be several cause of fire accident such as electrical Short circuit, Sparking due to loose electrical connection, Over Load electrical equipment, due to cooking appliances, Smoking, use of heater etc. Probability of fire Incident depends on nature of building such commercial, residential, warehouse, public building and presence of potential sources (Flammable materials), that results fire. Commercial building, multistory building, warehouse, hotel like building have potential of high risk of fire due to not follow safety laws and procedures and its results major harm in term of Death and property damage. Causes of Fire in building are:
- Inadequate storage of Combustible material in room of building.
- Cooking and cooking appliances, Heater, Oven used in building,
- Short circuit, loose electrical connection or overload electrical equipments and systems, Static electricity.
- Use of Candles and lighting, Smoking in building
- Flammable material storage or Fuel (LPG) gas cylinder storage near heat sources or live electrical equipment in building area.
Apart from this Fire Crackers, bursting of stove like factor also responsible to cause of fire.
In building, poor fire safety Parameter consideration during design such as fire exit, adequate height of building, ventilation, un-availability of fire fighting and detection system increases risk of fire. Poor method of flammable material storage and unawareness of Safety among people always also create risk and potential of fire accident occurring.
According to the National Fire Protection Association (NFPA), the most common causes of fires in commercial buildings are cooking equipment, heating equipment, electrical equipment and system, Smoking cigrates. Common cause of building fire are given in Figures 4.
As per case study carried out by Institution of safety Engineers (India) in month Dec. 2019, To collect data from different sources such as newspaper, Internet of past decade occurred fire accident and found that major numbers of fire accident were occurred, due to malfunction of electrical equipment and system including short circuit, sparking due to loose electrical connection, overload electrical equipment, electrical heater and second cause of fire accident are cooking and cooking appliances. Third cause is intentional fire such as misuse of heat source e.g child playing with lighter, matches, use of fire crackers, criminal activities etc. Apart from this flammable material storage near heat source, use of candles and incense stick, smoking were also cause of building fire in few cases.
2.1 How Fire Occur in Building
Fire is chemical reaction in which Combustible material combine with oxygen when external source of heat is applied. Combustion occurs continuously when oxygen, heat and a fuel source present (Fig.).In environment of building area, Oxygen is already available and combustible material come in contact with heat sources then fire take place. During fire, heat, smoke and light release and rapidly increases producing flammable vapors.
Fuel + oxygen (presence in air) = combustion of materials (mainly CO2) + Heat Energy and light.
Heat sources may be in the form of malfunction of electrical equipments, sparking due to loose electrical connection, cooking, smoking, misuse of lighter, use of heater etc. Flammable material may be in form of used material in building (wood), home appliances including cooking gas cylinder etc.

4. Consequence of Fire and Causes of Death in Fire Accident
The most obvious consequence of fire accident is damage to building, Property and loss of lives. In details, if analyze the impacts of fire accident, then found unexpected losses occurred that can’t recover easily or within short time period. Fire accidents lead to cause of Personnel death, injury and huge economic loss of society and country. Major fire fully burnt to building property It results poor country reputation as well as owner of building. Steel lost their Two-third strength, if temperature is increased 600 0 C therefore building strength also reduced. Timber and other material their nature is flammable can completely burn.
Most common cause of death during fire is suffocation due to inhalation of smoke, it include carbon mono-oxide (poising) and other toxic gas such as hydrogen cyanide due to burning plastic. Inhalation of carbon monoxide (CO) and other toxic gases that generates during burning, effect to human respiratory system, personnel unable to breathe and maintain required level of oxygen in body parts and its results Death. Carbon monoxide (CO) remove oxygen from blood stream rapidly enters all parts of the human body, including blood, brain, heart, and muscles. As per OSHA limits long-term workplace exposure levels to less than 50 ppm averaged over an 8-hour period. On average, exposures at 100 ppm or greater is dangerous to human health. Other Toxic gases such as phosgene can cause itchy eyes and sore in throat; at higher levels it can cause pulmonary edema and death. Released Smoke during fire are made of components, Particles, Vapours and toxic gases and effects to CNS, Heart, Kidney and such organ failure of human body results death.
Oxygen Level in atmosphere and Personnel health
| O2 Level in Atmosphere | Description |
| 21 percent | Normal outside air (Good for human health) |
| 17 percent | Impaired judgment and coordination |
| 12 percent | Headache, dizziness, nausea, fatigue |
| 9 percent | Unconsciousness |
| 6 percent | Respiratory arrest, cardiac arrest, death |
Table 1, Sources NFPA
In building Fire, hot steam, hot gases releases and material become hot due to burning and when Personnel come in contact with hot steam or Hot material, it lead to cause of burn injury and injury depend on Temperature value of hot material, hot steam or temperature of nearby place. Temperature above 50 degree are dangerous and may lead to cause of burn if temperature increases. Death occurring after a fire is effect of burns, infection, respiratory system failure, organ failure such as Kidney or heart failure, Abnormal clotting etc. is caused of major burn and most death occurred due to fire is within one days.
5. How can minimize the losses during Fire
Effective Fire safety control measure including emergency response plan (ERP), help to control risk related building fire. Losses depend upon Type of Fire, Nature and availability of material in building, Occupants in building and existing fire safety control measure. Effective existing Fire Safety control measure reduce the severity of harm of fire event. Fire Safety Control measure may be in form of presence of Fire Fighting System, effective implementation of Govt. rules and guidelines, Fire Safety Awareness among people, Evacuation plan, availability of emergency exit, emergency lighting, Avoid loose electrical connection and use of standard electrical equipment including power cable, distribution board etc. Immediate Rescue operation and presence of firefighting team can take needful action on time to prevent spread to fire and save lives. Avoid to use lift during fire accident. Incipient stage, shouldering stage and flame are stage of fire, if we control in initial stage then less probability of harm.
6. How to prevent Fire in Building
Fire accident in building can be control by to ensure adequate fire safety control measure parameter. Safety Control measure parameter may be in the form of passive or Active (Fig.12).
During design and construction, need to consider all parameter that are helpful to reduce risk up to acceptable level. Main objective to consider fire safety parameter is to minimize risk to prevent death, injury or building property or others who will be involve controlling fire and rescuing services during case of fire. During building design consider adequate ventilation, design large area into small area to provide effective fire barrier which is known as separation wall or compartments, Provide adequate exist including emergency escape route/exist for safe evacuation during fire.
Building material selection and construction such as use of non-combustible materials, fire resistant coating with building wall or structure, use less smoke emitting materials. Avoid using quick fire spread or flammable material for decoration in escape routes and kitchen room. Escape route must be constructed with high fire rating materials. Provide emergency lighting and signage in exist and access, it help to evacuate to occupants of building easily during fire. Room height should be adequate. Ensure Minimum two staircase with adequate hand railing and width of stair. The maximum travel distance from inside of the building to outside should be not more than 30 meters. Ensure Assembly point nearby building. Depute fire watchman to monitoring building time to time and take needful action to minimise fire related risk. Impart training time to time of occupants of building to create fire safety awareness. Display emergency contact no. including fire Station contact no. Ensure adequate fire prevention& Control system in building (Fig.12). Underground wiring, standard cable and power supply through adequate rating of circuit breaker, avoid to overload to electrical equipments help to reduce of potential risk of fire. Avoid to misuse of heat source such as lighter, matches and store to fuel gas cylinder such as LPG gas in suitable and safe place and check leakage time to time through soap bubble. Avoid smoking near wood furniture items or other flammable materials. Always ensure fire prevention system including detection, fighting& suppression system. Ensure all applicable compliance during design, construction and after using to building as per guideline of National building code (NBC) of India, National Fire Protection Association (NFPA) and respective state government guidelines and codes.
