What is an accelerant used for in forensic science?

An accelerant is a substance used to start or enhance the burning of a fire. In forensic science, accelerants are particularly significant in arson investigations, where the presence of such substances can indicate that a fire was intentionally set. These materials, which can be anything from gasoline to lighter fluid, facilitate the ignition and spread of flames.

Forensic scientists often collect samples from a fire scene to analyze for traces of accelerants. Identifying an accelerant can help establish motives, provide insights into the events leading up to the fire, and assist in the determination of whether arson was involved. This relationship between accelerants and fire behavior is why understanding their role is crucial in fire investigations.

Other options relate to different aspects of biology or medicine and do not connect to the context of forensic science as it pertains to fire investigations.
