Why is an uninhibited chemical chain reaction important? -
ANSWER-Uninhibited chemical chain reactions provide a
self-sustaining event that continues to develop fuel vapors
and sustain flames even after the removal of an ignition
source.
TRUE or FALSE: It is difficult to absolutely prevent static
electricity. - ANSWER-True.
What are some of the best fuels composed of? -
ANSWER-Hydrocarbons
The investigator should keep in mind that the point of the
leak may be ______ from the actual damage. - ANSWER-
Remote
TRUE or FALSE: Accelerated fires burn faster than non-
accelerated fires do, but they do not burn at higher
temperatures. - ANSWER-True

A copper conductor's melting temperature may be affected
by ______ - ANSWER-"alloying" or electric melting which
occurs when other metals such as aluminum or zinc melt
and come into contact with the copper and change its
melting temperature, usually lowering it.
What is a major skill of accelerant residue evidence
collection? - ANSWER-Knowing what to collect and what
not to collect.
What are fusible plugs? - ANSWER-Thermally activated
devices that open and vent the contents of a container.
If the investigation reveals that fuel gas may be involved,
the investigator should verify the ___ - ANSWER-
Presence of an odorant
When dealing with fuel gas systems, it is recommended
that the investigator seek _____ - ANSWER-Assistance
from someone who is experienced in this field to obtain
samples.
What are a few of the methods that cam be used to collect
samples of gaseous vapors? - ANSWER-Commercially
,3|Page
available sampling devices. Evacuated air sampling
devices
Where do the most common leakages in fuel gas systems
occur? - ANSWER-Pipe junctions, unlit pilot lights/burners,
uncapped pipes, malfunctioning appliances and controls,
areas of corrosions, and points of physical pipe damage.
What is OSHA and why is it important? - ANSWER-
Occupational Safety and Health Administration. OSHA
requires that private and public employees have a
workplace that is safe and OSHA has identified five
particular elements.
Physical evidence can be produced in court or other
proceedings if it is properly ____ - ANSWER-Identified,
documented, preserved, and analyzed.
Products such as wood and paper must first _____ to
produce char. - ANSWER-Pyrolyze
Starting after 1970, modern carpet made in the US is
made to ______ - ANSWER-Comply with a specific fire
resistance standard.

What basic incident information should be obtained during
initial assignment and response? - ANSWER-Location of
incident. Date and Time. Reporting party/discovering
party. Weather conditions. Size and complexity. Type and
use of structure. Nature and extent of damage. Security of
Scene. Purpose of investigation
What is Ohm's Law? - ANSWER-A basic law of electricity
that defines the relationship among voltage, current, and
resistance. If two of these values are known, it is possible
to determine the third.
What is a protocol? - ANSWER-A description of the
specific procedures and methods by which a task or tasks
are to be accomplished.
What is fire point? - ANSWER-The lowest temperature at
which a volatile combustible substance continues to burn
in air after its vapors have ignited.
Fire effects include things such as: - ANSWER-Loss of
material. Straining, bending, charring, spalling.
Calcination. Oxidation. Color changes. Melting. Annealing.
Alloying. Crazing. Soot and smoke deposit and removal
