Detection accelerators arson


Detection accelerators arson

If burned warehouse, pillow devastation and destruction, and the heat was and smoke fill the place, and flame spread, and the walls and the ceiling is falling apart, can determine whether the fire was intentional or unintentional?
Accelerators: The investigating fires analyze evidence to estimate how the fire started? Where is the spread? If there is no doubt that the fire deliberately, the likelihood contribution Accelerators (substances that accelerate the spread of fire if used) is out of the question.

Properties Accelerators: Accelerators can be useful if used as fuel, and can be dangerous if used in the fires; are strong solvents, absorbs quickly and does not mix easily with water and float it often, and in normal temperatures produces accelerators fumes can be ignited.

Signs and Accelerators: signs of the presence of accelerants combustion pattern is normal, including the combustion pattern tumbling as in the picture, has been poured combustible liquid in this region, and spread between floor panels to lower symptoms.
Other indicators of the presence of small patches on the surface of any material moist, and if investigators felt like these spots they take samples to be tested.
Chemical Analysis: take investigators any samples they collect to the laboratory for analysis chemically, and there separating the components of each sample from each other in a process called "chromatography gas" which makes components appear in graphic form (Chromatogram), and these forms like fingerprints; They characterize each article, Comparing Figure (chromatogram) of unknown substance with known forms for technics can determine the type of accelerator.
