What is the purpose of identifying and documenting fire patterns related to arc sites?

Identifying and documenting fire patterns related to arc sites is essential for determining the area of fire origin or spread. Fire patterns can provide critical insights into how the fire developed and progressed, which is vital for investigators seeking to pinpoint where the fire started. Arc sites, areas where electrical arcing has occurred, can indicate instances of electrical malfunctions that may have initiated a fire. By analyzing these patterns, investigators can establish connections between the arc site and the fire's origin, leading to a better understanding of the sequence of events that unfolded during the incident. This information is crucial in both determining the cause of the fire and providing accurate evidence for any subsequent investigations or legal proceedings.
