Arriving at the Scene

Fire Investigators/ Arson Inspectors are to be called out to the scene of a

fire. Inspectors evaluate the scene, identify witnesses, and survey what must be done. The lead

investigator must make contact to establish presence, define the scene’s boundaries, identify and

interview witnesses at the scene, assess scene security at the time of the fire, and identify resources

required to process the scene. Once the scene is determined to involve an arson or other crime, the

investigator must address legal requirements for scene access, as well as search and evidence

seizure. The investigator should then meet with the incident commander and first responders to

assess previous events and the current status of the fire scene, make introductions, identify

essential personnel, and determine scene safety and integrity issues. Investigators shall conduct a

briefing with the incident commander to determine who has jurisdiction and authorization (legal

right of entry) and to identify other personnel at the scene (e.g., law enforcement, firefighting,

emergency medical services, hazardous materials personnel and utility services personnel). They

will need to determine initial scene safety prior to entry through observations and discussions with

first responders. Consider environmental as well as personnel safety concerns. Assess changes in

safety conditions resulting from suppression efforts. The investigator should perform a preliminary

scene assessment, determine the area in which the site examination will be conducted and establish

the scene perimeter (an overall tour of the fire scene to determine the extent of the damage,

proceeding from areas of least damage to areas of greater damage.) This is to identify areas that

warrant further examination, being careful not to disturb evidence. Also, they will inspect and

protect adjacent areas that may include nonfire evidence (e.g., bodies, bloodstains, latent prints or

tool marks) or additional fire-related evidence (e.g., unsuccessful ignition sources, fuel containers

and ignitable liquids). If need be, Investigators will mark or reevaluate the perimeter and establish

the procedures for controlling access to the scene. Identify and interview witness(es) at the scene.

The investigator should determine the identities of witnesses and conduct interviews. Incident

commander, identify first responders and first-in firefighters, and arrange to document their

observations either in writing or through recorded interviews. It is important to know who reported

the fire. Secure a tape or transcript of the report if available. The owner of the building/scene, any

occupants, and the person responsible for property management needs to be identified as well as

those who may have left the scene. Identify and interview other witnesses (e.g., neighbors and

bystanders) and record their statements. Assess scene security at the time of the fire. The

investigator should determine whether the building or vehicle was intact and secure and if intrusion

alarms or fire detection and suppression systems were operational at the time of the fire. The

investigator should ask first responders where an entry was made, what steps were taken to gain

entry to the building or vehicle, and whether any systems had been activated when they arrived at

the scene. Observe and document the condition of doors, windows, other openings, and fire

separations (e.g., fire doors). Attempt to determine whether they were open, closed or

compromised at the time of the fire. Observe and document the position of timers, switches,

valves, and control units for utilities, detection systems, and suppression systems, as well as any

alterations to those positions by first responders. Contact security and suppression system

monitoring agencies to obtain information and available documentation about the design and

function of the systems. Investigators should identify a distinct origin (location where the fire

started) and an obvious fire cause (ignition source, first fuel ignited, and circumstances of the event

that brought the two together).

Documenting the Scene

Complete an accurate documentation of the fire scene consists of good field notes,

diagramming/sketching the fire scene, photographing the fire scene, and collecting fire scene

evidence. Use notes, photos, and sketches to document the evidence collection process. Remember

to make notes and sketches pertaining to the collection, and photograph the collection of each piece

of evidence. Just as in photographing the fire scene, you need to document evidence in a similar

fashion. This documentation is done on an evidence log.

 

Completing the investigation

Once evidence has been collected and processed, the investigator must complete the

investigation and release the scene. Submit reports to the appropriate databases. The responsible

agencies must file incident reports with the appropriate databases. Detailed fire information is

collected, integrated and disseminated through national and State databases. These data help

authorities identify fire trends and develop innovative procedures and equipment.
