Cotton waste found at a fire scene could indicate which of the following?

The presence of cotton waste at a fire scene can indicate a potential trailer. A trailer is a material used to spread fire from one area to another, and cotton waste is highly flammable due to its composition. When cotton or similar materials are found at the scene, it raises suspicion that they may have been intentionally used to facilitate the spread of the fire, especially if they are located in strategic places near ignition points. This connection helps investigators look for signs of arson or the deliberate manipulation of fire patterns.

In contrast, while cotton may burn readily, it does not typically serve as an accelerant in the way that liquids like gasoline would. Additionally, cotton waste wouldn't function effectively as a type of igniter, which usually refers to items that initiate combustion. Lastly, cotton is not a fire retardant; it lacks properties to inhibit fire spread and is instead a combustible material. Understanding the role of different materials in fire investigations is crucial for determining fire origins and potential causes, especially in cases of suspected arson.
