Which practice is essential for fire investigations?

Interviews with witnesses form a cornerstone of fire investigations as they provide critical information regarding the circumstances surrounding a fire incident. Witnesses can offer valuable insights about the events leading up to the fire, including any unusual activities, sounds, or behaviors observed prior to the incident. Their accounts help investigators piece together a timeline and understand the conditions that may have contributed to the fire starting or spreading.

Gathering firsthand accounts is crucial in identifying potential causes, whether they be accidental, intentional, or the result of negligence. Additionally, witness statements can help corroborate physical evidence collected at the scene, leading to a more thorough analysis and understanding of the incident. This firsthand information is not typically available through other means, making interviews with witnesses an indispensable practice in the investigative process.
