Which statement about collecting samples for flammable liquids is true?

The statement that synthetic materials in furnishings share the petroleum-based origin with accelerants is accurate because many synthetic materials, such as those used in upholstery, carpeting, and plastics, are derived from petroleum products. This correlation is significant in fire investigations, particularly when analyzing for the presence of flammable liquids. The presence of synthetic materials may complicate the analysis, as they can potentially mask or simulate the characteristics of accelerants.

Investigators often need to distinguish between the residues of these synthetic materials and any potential accelerants that were used in a fire. Understanding this relationship is crucial for accurately interpreting the fire scene and determining whether an accelerant was employed. The inherent similarities in the chemical structures can lead to challenges during testing, making it essential for investigators to have a thorough understanding of both synthetic materials and accelerants.
