UniversityDecember 24, 2010Fire investigationsFire can spread from item to item by radiation from flames or by radiation from the developing hot smoke layer. To create and sustain a fire three factors must be present. The three factors are known as the fire triangle. The fire triangle consists of oxygen, a fuel source and heat. In most cases the fuel must be above 16%, the fuel may be any flammable substance, the heat source needs only to match the ignition temperature of the fuel. For rapidly spread fire, there may be use of accelerants which add to the fuel load such as kerosene, gasoline or alcohol.
It should be noted that the existence of such accelerants and other flammable fuels at the origin or location of fire such as wood and grass, spreads the fire even more. The heat from a fire can affect a structure in the case of a floor which starts to sag, when it starts to expand hence pulling in the bulding’s frame and hence the columns of the house. A fire can be accidental such as faulty gas or unintentional tipping of a candle or an arson fire such intentional tipping of a candle with the intent to cause and spread fire. Out of a fire there results investigation to determine the cause and origin of the fire, hence the fire investigation.
It is necessary to investigate origin and cause of that fire since it represents great threat not only to the well being of individuals, but also, to the welfare and security of there community as a whole. With the data it will be better to determined what the problem areas are and how to deal with them.
This data helps to effectively allocate the money in budgets for education and measures in catering to fire. This brings to solutions and engineering designs to prevent previous fires. These include reducing wood construction, combustible roofing materials, and crowded building conditions. Fire investigators also come in as those who undertake the cause and origin of the fire. During the investigation, three factors will be taken into consideration, the source of ignition or heat which may be an electrical or smoking material, I.INTRODUCTIONThe fire occurred on 13th December 2009 at 2.00 p. m on Hannington Road which provides residential housing.
The fire service, i.e the Hannington Fire Brigade Service, a report of a fire at that prescribed addresses. The report was received by a several phone calls from residents of Asili Block, the neighbours of the occupant whose apartment had caught on fire. The immediate commanding officer of Hannington Fired Service responded to the scene. The weather at the time of the alarm was relatively hot at 30 degrees Celsius with a clear blue sky, however it was relatively windy. On that same day the State Fire Investigation Unit received notification of this fire from the Hannington Fire Service.
Officer Withers responded to the scene on that same day and initiated an investigation into the origin and cause of the incident. She was assisted in this investigation by a junior colleagues, Officer Charles and I, Officer Rachael. As a result of this investigation, the cause of the fire was ruled accidental. The case has hence been closed at this time.
