b. approximation approach
c. methodology approach
d. general approach - ANSWER-a. systematic approach
With few exceptions, the proper methodolgy for a fire or explosion investigation is to first
then investigate the cause, circumstances, conditions, or
agencies that brought the ignition source, fuel, and oxidant together.

b. distorted
c. failure
d. faulty - ANSWER-c. failure
Vehicle fire inspections may present many other situations that pose safety hazards to
the investigator. These can include:

vehicle are primarily used to locate the .
a. origin of the fire
b. potential ignition sources
c. fuel loads
d. all of the above - ANSWER-d. all of the above
A wide variety of materials and substances may serve as the first materials ignited in
motor vehicle fires. These include engine fuels; transmission,·power steering, and brake
fluids; coolants; lubricants; and the vehicle interior materials or cargo. Once a fire is
started, any of these materials may contribute as a secondary fuel, affecting the fire
growth rate and the ultimate damage sustained.
