They always make it appear so simple on tv. The arson expert steps to the fire scene investigation site, and in the first half hour has a conclusive theory as to whether it was arson, and who may have conducted it. If only it were that easy in real life. It could be difficult, at times maddeningly hard, for investigators to distinguish an arsonist from what little proof was left out. There are ways to carry out in this form of investigation, strong steps which have been tested to provide the most evidence in instances of arson. It starts off with observation on the part of the investigators as soon as they can get to site of the fire, finding what clues they could, and following them to have the answers they seek.
Point Of Origin
All of fires have a place of origin, some blatantly so, while others may be subtly hidden behind overwhelming proof to the contrary. This is where the intuition, observation abilities, and several years of experience on the part of the fire scene investigation members come in. It is often hard to determine exactly where an investigation will break, but it will be those qualities of the investigators engaged that will bring it about. The very first thing to find when the investigation begins is the point of origin for the fire, as well as the evidence that surrounds it.
Observing the location, and also the course of the flames is the first clue that could lead to finding the place of origin. During a fire scene investigation, there is a lot within the environment of the fire that can affect how simple it will be to identify the place of origin. The building's structure, any particular features within it such as fireplaces and stairwells, and even the construction supplies utilized to make the building could all affect how the fire spreads from the place of origin. Even if the fire was actually made up of several blazes, there might have been only one actual origin point, and that must be discovered before anything else could be identified.
Color
After the place of origin has been identified, there are other properties regarding the fire itself that will help determine whether it happened due to arson, or mainly because of other causes. This point of the fire scene investigation will usually involve talking to the fire crews who worked the blaze, as well as other possible witnesses. The height and also colour of flames during a big fire could reveal something about how precisely the fire was started, as well as what exactly may have ignited it. The colors of a fire can turn from red to yellow for different factors, and there are specific things which will trigger a color change as it is consumed by the flames. The color of the smoke is important also, as a thick, black color smoke will indicate the presence of a carbon based fuel source, such as gasoline. This is why such witnesses play a crucial part in the investigation, simply because they were there as it happened, where the investigators were not.
Smells
The smells and odors found at the place of a fire could also have an impact on a fire scene investigation. While many individuals might think that all forms of gas smell alike, they'd be wrong. A person properly trained in determining potential causes of a fire will know the distinction in scent between gas and also diesel fuel, for example, whilst outsiders may not. There is also a marked distinction in odors left behind by consumed construction materials, just like tar and paint, that may be missed by the casual observer. A saturation of such odours may reveal that one of the substances was used as an accelerant, especially if it shows up in an area where it might not have been in usual circumstances.
