Contact Us Fire Investigation Fire investigation involves the examination of all fire-related incidents once firefighters have extinguished the fire. The practice is similar to the examination of crime scenes in that the scene must be preserved and evidence collected and analysed, but with numerous additional difficulties and dangers.

The investigation will include closely surveying the damaged scene to establish the origin of the fire and eventually establishing the cause. However in order to effectively examine and evaluate a fire scene, it is imperative that the investigator has a detailed knowledge of the chemistry and behaviour of fire and its effects.

In order for a fire to occur, three vital components must be present: Together these make up the fire triangle. A fourth factor can also be described — a self-sustaining chemical chain reaction — to produce the fire tetrahedron.

The absence of any of these conditions will result in a fire not starting or extinguishing through smothering oxygen removalcooling heat removal or starving fuel removal. Solid and liquid materials do not actually combust, but the process of heating causes them to produce vapours which can burn.

This is the process of pyrolysis. Through this pyrolysis products will be formed, flammable and volatile substances of low molecular weight caused through the decomposition of materials by fire. The colour of flames can vary depending on the materials involved in the combustion.

The colour of a flame is basically determined by the wavelength of light emitted, which varies depending on the material. Inorganic substances can produce more obvious colour differences, such as copper which will cause a green flame.

Heat produced by a fire can spread in one of three ways; convection, conduction and radiation. Convection is the transfer of heat through air circulation, and only occurs in liquids and gases.

An example of convection is the heat from a fire rising and heating the ceiling of a room. Conduction is the transfer of heat through a medium by direct contact, such as a fire heating a metal beam which transfers the heat elsewhere.

Radiation is the emission of heat as infrared radiation without a medium, such as a fire heating and igniting a nearby sofa. Ignition Ignition will occur when all required conditions to start a fire occur, producing either a smouldering or flaming fire. This will often be induced by the addition of heat to a fuel in air, which can be caused by various sources such as exothermic chemical reactions, friction, solar radiation and electricity.

The temperature required for ignition to occur varies depending on the fuel. The flash point is the minimum temperature at which fuel favour is momentarily ignited in air by an external ignition source. However this will not necessarily sustain combustion and produce a fire. The flame or fire point is the minimum temperature at which enough vapour is produced to allow continued combustion.

This is usually a few degrees higher than the flash point.And Roger Stone, a longtime adviser to Trump, communicated with a self-described hacker, Guccifer , in August who US intelligence officials believe was a Russian prop.
