DETERMINING CAUSEIn most jurisdictions the fire chief has the
legal responsibility for determining the cause and origin of a fire.
Delegates this authority to the fire officers and firefighters at the scene - Are you experienced enough to make the determination –
Remember your finding may go to court if in doubt get help – when should you get assistance in determining the fire cause
Hermiston Policy on Fire Investigations
There has been a death or injury related to the fireThere appears to have been criminal acts associated
with the fire (incendiary fires, chain of dumpster fires)
The fire caused a loss of high dollar value - $10,000 or more
There is not a clear and believable explanation for how the fire started
A request is made for utility companies to respond to the scene (utilities were shut off)
Flames or heavy smoke are showing from a structure
Hermiston Policy on Fire InvestigationsYou are unable to clearly determine the cause of a
vehicle fireThere are suspicious circumstances pertaining to the fire When in doubt about whether an investigator is needed,
call the investigator and explain the circumstances. The investigator will determine whether an investigation response is necessary.
If no fire investigator is available it will be the Senior Fire Officer’s responsibility to determine the fire cause and to thoroughly document the fire cause investigation.
Most important thing a firefighter can do is OBSERVE Observations enrouteWeatherTime of day, –BarriersPeople leaving the sceneDoes your department make you fill out a
Fire StoryRemember you could have to go to court on
this fire – How good is your memory

Observations During The FireIncendiary devices Trailers Structural alterations Fire patterns What would you do if you saw this?
Observations During Fire Fighting Operations Heat intensity - what would this mean - NOTHINGAvailability of documents Fire detectionprotection systems Intrusion alarms Location of fire
Observations During Fire Fighting Operations Personal possessions Household items Equipment or inventory Business records Note – do not touch
Conduct and Statements at the Scene It’s not your job – put the fire out, keep your
mouth shut and OBSERVE – If the owner or occupant wants to talk send
them to the fire officer or investigatorFire Investigators Interview – Police
InterrogateWhat is the differenceKeep your opinions to the fire to yourself – I
talk to the Incident Commander – If you have an observation or did something I want to know
Conduct and Statements at the Scene Public statement regarding fire cause should
be made only afterThe investigator and ranking fire officer have
agreed to its accuracy and validityUntil the investigation has been completed its
under investigation– no fire is suspicious or suspected arson,
Classification of cause must be accidental, incendiary, natural or undetermined
Investigator or Fire Officer speaks to the media
Responsibilities After the Fire Firefighters should report their observations
to their supervisorFirefighters should not discuss their
observations with other crew members, families or friends – I do not want to hear how the fire started from the press or at a store
Responsibilities After the Fire Improperly done overhaul operations can be
detrimental to the investigation Put the fire out Clear the smokeGet an investigator to look at the fire scene
Do not remove anything from the fire until given permission from the fire investigator
Securing the Fire Scene Fire department has the authority to deny
access to any buildingDuring fire fighting operations For a reasonable length of time after fire
suppression is terminated Maintain custody till fire investigators arriveGet a Permission to Investigate signed as soon
as possibleWhy must we maintain custody of the scene
Protecting and Preserving Evidence Protect evidence by keeping it untouched and
undisturbed until an investigator arrives Do not gather or handle evidence unless it is
absolutely necessary in order to preserve it Note if you handled evidence – chain of
custodyIf you must move evidence- try to take photos
and write in the fire story on why you moved it
Protecting and Preserving Evidence Firefighters must avoid trampling over possible
evidence and obliterating it The same precaution applied to the excessive
use of water may help avoid similar unsatisfactory results
Do not remove anything that you do not have toHuman footprints and tire marks must be
protectedProtect completely or partially burned papers
found in a furnace, stove, or fireplace by immediately closing dampers and other openings
Leave charred documents found in containers
After Evidence Has Been Collected After evidence has been properly collected by
an investigator, debris may be removed - ask the investigator what is ok to remove
Remove charred materials to prevent the possibility of rekindle and to help reduce smoke damage
SummaryYour job is to observeIt is a firefighter ‘s responsibilities is to avoid
disturbing or destroying evidence while fighting the fire and after. In the area of origin appropriate caution must be used when spraying water, moving debris, and even walking around.
Once the fire is out if possible get an investigator in there to determine where and what to overhaul
Firefighters should not determine cause No statements to anyone about the fire
