Certified Fire Investigator Practice Exam

What is the first step in conducting a fire investigation?

1. Photograph the scene

2. Interview witnesses

3. Make contact with the Incident Commander

4. Check for ignition sources

The correct answer is: Make contact with the Incident Commander

The first step in conducting a fire investigation is to make contact with the Incident Commander. This is essential because the Incident Commander has overall responsibility for the incident scene and can provide critical information regarding the circumstances of the fire, including details about the response actions taken, any hazards present, and the condition of the site. This contact also allows the investigator to understand the chain of events and gather pertinent details about evacuations or potential witness availability. Establishing this communication early in the investigation helps to ensure that the investigator is aware of any ongoing operations, safety concerns, or evidence preservation needs. It sets a foundation for the investigation process, ensuring that all subsequent steps, including photographing the scene, interviewing witnesses, and checking for ignition sources, are carried out with a clear understanding of the event's context and conditions.
