- Testimonial
Term
What is the process of re-creating the physical seen before the fire occurred either physically or theoretically
Fire scene reconstruction
What is the first step and fire calls determination
Identify the point of origin
U and V shape fire patterns can lead to
Point of origin
What does the cause of fire refer to?
Circumstances in factors that were necessary for the fire to have occurred
Logical, systematic examination of an item, component, assembly, or structure and its place in function within the system, conduction to identify analyze the probability, cars, and consequences a potential in real failures
Failure analysis
What is the scientific process of examining a fire occurrence to determine all of the relevant facts including the origin, calls, subsequent development of fires, as well as to identify the responsibility for whatever occurred
Fire analysis
As part of a fire investigation the fire officer may have to interview
Fire victims
Witnesses
Firefighter
Suspected perpetrators
What type of fires are influenced by environmental conditions, topography, feel old, wind, whether

Spite / revenge
Extremism
Vandalism
What does the investigation report include
Information in chronological order, beginning with a description of the structure before the event occurred
Where as a witness can provide the court with testimony based only on his or her personal knowledge and observations an expert witness has
Scientific, technical, and specialize knowledge I can’t be relied on to interpret the fax
Term
An agent often any Maneval liquid used to initiate a fire or increase the rate of growth or spread of fire
Accelerant
Term
The crime of maliciously and intentionally or recklessly starting a fire or explosion
Arson
Term
The remains of the material FIRST ignited, technician source, how are the items are components in someway related to the fire ignition, development or spread. An artifact may also be an item on which the fire patterns are present, and wish the case the preservation of artifact is not focused on the item itself but rather the pattern that appears on it
Artifact
Term
carbonaceous material that has been burned and has a blackened appearance
Char
Term
Tangible items that came identified by witnesses such as incendiary devices in fire scene debris
Demonstrative of evidence
Term
And it’s in written form such as Reports records photograph sketches and witness statements
Documentary evidence
Term Luminous discharge of electricity from one object to another, typically leave in a blackened of object in the immediate area
Electrical arc
Term
The documentary or oral statement in the material objects admissible as testimony in the court of law
Evidence
Term
With the ignited material is being used for (clothing cotton etc
Form of material
Term
The destruction distillation of organic compounds in an accident free environment that converts the organic matter into gas is liquids or char
Pyrolysis
Term
With night at material it’s made of(can be cotton)
Type of material
What are trailer
Material used to spread fire from one area of a structure to another
Fire investigator 1033
A fire investigator might also be called in situations that could cause great harm such as fire in a hospital or college dormitory even if the was quickly control
Conduction, convection, and radiation at three methods of
Heat transfer
Fire grows and develops if I was the same pattern it as the
Smoke in here, rising tour of the ceiling, spreading out, and baking now
The origin of the fire is typically at the base of the V or U shape pattern that is also known as
Fire patterns
V or U shape me patter is also known as
Movement pattern
Determining the point of origin requires the analysis of the information from four sources
Physical marks or fire patterns
Observations by the Person who witnessed a fire
Physics and chemistry a fire initiation development and growth
Noting the location of electrical arcing has caused damage
After all investigative probabilities have been exhausted, if two or more potential causes remain the cause of the fire is To be considered
Undetermined
If the cars is related to a mechanical malfunction, the exact cause may not be established without the assistance of a
Automotive expert
What are the 3 components of IGNITION source
Generation (produce heat energy to raise the fuel to ignition temp)
Transmission heat energy transmitted from source to fuel to raise the fuel to it ignition temp( conduction convection, radiation)
Heating (heat transfer from to fuel must continue long enough got fuel to be heated to it ignition temp)
47% of vehicle fires are?
Mechanical
What is the first objective the most vehicle fire investigation
Indications of arson
Wildland fires are influenced by environmental conditions. How are wildland fires vertically spread

Any fire that you deliberately ignited under circumstances in which the person knows that the fire shit not be ignited is a
