In fire investigation, arc mapping is primarily used for what purpose?

• A. Determining potential electrical causes
• B. Mapping heat spread during a fire
• C. Illustrating building structure
• D. Documenting fire spread across different materials

Answer: (A)

Arc mapping is a critical tool in fire investigations, specifically utilized to determine potential electrical causes of a fire. This technique involves analyzing the patterns of electrical arcs that may have occurred during an incident. By documenting these arcs, investigators can identify specific electrical circuits, appliances, or devices that may have contributed to the ignition of the fire. The evidence gathered through arc mapping helps in reconstructing the fire's origin and understanding if faulty wiring, short circuits, or other electrical problems were present. This information is crucial, as it can lead to conclusions regarding liability, adherence to electrical codes, and the overall safety of the electrical installations at the site of the fire. Mapping heat spread, illustrating building structure, and documenting fire spread across different materials, while important aspects of fire investigation, do not specifically relate to the identification of electrical causes, which is the primary focus of arc mapping.
