Investigators look for signs that the fire was provided with an unusual amount of heat or a volatile accelerant, suggesting human intervention rather than a spontaneous event. While the fire triangle explains the physics of combustion, arson evidence focuses on how a human actor might manipulate these elements to start or accelerate a fire.

Therefore, the investigation report must be meticulous, detailing every step taken from the arrival at the scene to the final conclusion, ensuring the evidence holds up under legal scrutiny. Investigators use specialized tools, including hydrocarbon sniffers and canines, to locate trace amounts of fuel vapors.
They collect samples of debris from the suspected point of origin, sealing each sample in airtight containers to prevent the loss of volatile compounds. Removing any one of these components will extinguish the flame, and this principle forms the foundation of arson investigation.

The goal is to move beyond the assumption of accidental ignition and determine whether a criminal act introduced the flame. This process relies on a combination of physical clues, chemical analysis, and behavioral context to build a defensible conclusion.
