What should investigators aim to achieve with arc mapping?

Investigators utilize arc mapping primarily to analyze the relevant sequence of events during a fire investigation. Arc mapping is a technique that involves plotting the locations of electrical arcs and the patterns they create in relation to the fire scene. By doing this, investigators can determine the path of the fire's ignition and how it progressed over time. This information is crucial for constructing a timeline of events that led to the fire, thus helping to identify not only the origin of the fire but also potential causes.

Understanding the sequence of events allows investigators to piece together how different factors, such as electrical activity or combustible materials, interacted prior to and during the igniting process. Consequently, this method serves as a foundational tool in fire investigation, aiding in the formulation of a coherent narrative regarding the circumstances surrounding the fire incident.
