Fire is that element which destroys everything including the source and origin. Along with this, those who investigate the scene also work under extreme risk. It is important to ensure their safety before doing anything. The officer who receives the call and arrives at the scene before everyone, works under pressure of making sure that everyone is safe and the injured are getting proper treatment.
The investigation begins right from the call for help. The officer, who gets the call, makes sure to get the name and number of the caller. Once this is done the officer gets the address of the location where the outbreak has occurred.
Arriving at the Scene
This is a critical task. To respond successfully is being observant of everything. The officer will have to keep an wary eye everywhere. From a passing car to a harmless looking person standing at the side of the road can be important. Due to this the officers are trained to be watchful.
The first thing the investigators ensure while investigating house fire is that everyone is out of the proximity of the flame. In case of an injury or death, the investigation takes a complicated turn. However, before the process begins, it is important to determine whether the insurance agency will take the responsibility of the investigation or the crime department.
The investigators look for some specific evidence. Blood stain is vital evidence. It is not easy to lift blood samples. In case of fire, these stains get erased and due to that evidence collection gets even more difficult. However, to lift the stains, the investigators need to identify the areas where the stain could be found.
The specialist working on the scene need to ensure that the contamination of the scene is prevented. However, this is not an easy task. To prevent contamination, the investigators need to employ less manpower. Crime scenes get sabotaged with people walking around and touching things. The scenes of fire suffer such a fate even before the investigators arrive at the scene. To defuse the flame, fighters contaminate the scene.
Location from where the evidence is found plays an important role. The investigators document each location while they collect the pieces. They even sketch images for later use. Photographing the scene is another way of documenting the location.
Once the pieces are collected, they place them inside different jars and bottles. These bottles are labeled with the names of the locations and other important details.
Behavior of the flame is essential and the investigator needs to read this. Flames spread at a certain pace. If this pace differs, the investigation takes another turn. The arson specialists need to read the behavior of the flame step by step. For this they receive special training.
Once everything is done, they let go of the scene and turn it over to the police officers. However, before releasing the scene, they need to recheck whether everything is properly done and all the areas are rightly covered. After this they submit everything to the lab.
