In a forensic context, what could be considered an accelerant?

An accelerant, in a forensic context, refers to any substance that is used to enhance the ignition and spread of fire. Common examples of accelerants include gasoline, lighter fluid, and other flammable liquids. These substances can play a crucial role in arson investigations as they are often used to intentionally start and accelerate fires, making it important for forensic scientists to identify them at a fire scene. The presence of accelerants can help forensic experts determine whether a fire was set intentionally or was accidental.

In this context, the other options do not meet the definition of an accelerant. For instance, forensic chemical reagents are typically used for analysis and testing, such as identifying substances or conducting chemical reactions in labs. Enzymes useful for DNA testing are biological catalysts that facilitate the processing of DNA samples but are not related to fire. Features of postmortem changes refer to the physical and chemical transformations that occur in a body after death, which also have no relation to fire ignition or accelerants. Thus, the correct identification of an accelerant is critical in the investigation of fires to understand their cause and origin.
