What is the importance of fire investigation?
Fire Investigation is a way of investigating the cause and origin of fires, which involves arson fires and accidental fires. Fire prevention is easy to understand, but its definition is the act of teaching the public of ways to prevent fires in homes, schools, businesses, and other places that a fire can occur in.
Why is fire investigation important in all fire incidents?
The purpose of a fire investigation is to determine how the fire started and why the fire behaved the way it did. Data collected through fire investigations is a key element in addressing a community’s fire problem. Fire investigation is one of the most important ways of identifying our targets.
What are the three basic purposes of fire investigation?
With few exceptions, the proper methodology for a fire or explosion investigation is to first determine and establish the origin(s), then investigate the cause: circumstances, conditions, or agencies that brought the ignition source, fuel, and oxidant together.
How do investigators determine the cause of a fire?
To determine the cause of such a fire, investigators rely on a number of observations and techniques, from telltale signs of flames to satellite imagery and chemical tests. Kennedy and Associates, which analyzes fires and explosions for insurance companies and trials.
What types of evidence do fire investigators collect?
Fire and arson investigators examine the physical attributes of a fire scene and identify and collect physical evidence from the scene. During the scene examination, investigators may find evidence such as accelerants, tampered utilities, and specific burn patterns, which may indicate criminal activity.
What is the most common container used to collect fire debris evidence?
All fire debris evidence must be submitted in vapor-tight containers such as glass “mason” jars with screw-on lids or lined metal cans with friction fit lids. Unlined metal cans are not acceptable containers. Paper and/or plastic bags are not vapor-tight containers and will not be accepted by the laboratory.

Fire suppression forces have four functions with respect to fire investigation on the scene: observation, recognition, preservation, and notification. Firefighters must recognize physical evidence, which helps the investigator determine the area of fire origin. Preservation.
What are the factors that affect materials during a fire?
Rate of burning and heat output for surface and crown fires are influenced by fuel load, fuel moisture, topography, ignition method, air temperature, wind, and relative humidity. Heat output and burn rate for smoldering are influenced, in part, by the fuel moisture and inorganic content of the duff (Frandsen 1989).
What three main factors influence how a fire will burn?
Fire behaviour refers to the way that a fire burns, including how quickly it spreads, how much heat it gives off and how much vegetation it consumes. Three major factors typically influence fire behaviour: weather, fuels and topography.
