Billions of dollars are lost due to damaged properties as a result of arson activities. However, only 17% of the arson-related cases results to arrest (Lentini, 2012). A fire incident is considered as arson after ruling out all accidental cases of the fire. Therefore, the investigator is mandated to prove that a person deliberately caused the fire with harmful intentions. A fire arson is a difficult and detailed situation to investigate considering that the incident was well planned, but the proprietor is not present during the act and the destruction us tremendous.

It is crucial for an arson investigator to starts examining the scene immediately after the fire has been put off because, first, to identify the origin and cause of the fire, and also provide an effective conclusion on whether the fire incident was natural or accidental. The importance of identifying the cause of the fire is to eliminate the probability of occurrence of similar incidents in future. In this case, the investigator mainly focuses on the ignition devices or the accent. For example, the presence of petroleum accelerants residue in the soot can be a clear indicator that an arsonist started the fire.

Secondly, it is important for the arson investigator to examine the scene to determine its safety. A fire scene has numerous risk factors that lead to probable hazards, for example, the presence of heated materials, toxic burning products, structural collapse and presence of gas mains and electricity (Sandercock, 2008). The investigator should conduct a thorough risk assessment of the scene, and if declared safe, all the personnel entering the scene should wear protective clothing, for example, the fire resistant overall, hardhats and the steel capped boots.

Thirdly, the investigator should assess the scene to determine if there was any witness to the scene. An eyewitness may provide crucial information of the scene before the fire and also the details of the incidence itself, for example, the presence of suspicious activities in the scene and also the nature of the fire spread and the color of the smoke. The on lookers may have taken videos of the fire incidence with their phones or cameras, information which may be crucial in the fire investigation. It is important to consider that the public witness may be depended on since they may have taken part in the fire incidence, the emergency service personnel are the most reliable witness. For example, the firefighters may provide information on the probable source of fire or any other unusual conditions observed.

Also, the fire tends to burn upward thus the base if the fire is expected to be at a lower point of burn. The structural damages may also act as a good indicator of the origin of the fire since most buildings collapse in a way that the point first affected by the fire is clear. These factors of a primary scene search help to identify if the fire incident was natural or accidental to prevent the occurrence of such a case in the future.
