3. The presence of flammable accelerants may indicate that the fire was Incendiary. Which of
the following is not an indicator of the use of flammable accelerants? (Sec. 3.7, 3.11,
6.5.3, 6.5.4)
(A) Charring of the floor or low burn marks on the wall or under the door or on the lower part of the door.

(B) Char in broken patterns or “puddle-like” circle bums on the floor.

(C) Low burning and deep charring.

(D) Heavy body of fire with little contents. Accelerants increase damage.

 

(E) “V” Pattern of burning on a wall.
 

E

V PATTERNS HELP IDENTIFY THE POINT OF ORIGIN

 Absence of "V" Pattern of burning could mean an accelerant was used. Rapid intense heat from accelerant may cause perpendicular burns on
walls.

7. As your unit is overhauling at a Private Dwelling fire, one of your members notices what
appears to be a flammable liquid floating on water that has accumulated on the floor. After you
notify the IC, you are ordered to collect the flammable liquid due to the Fire Marshals currently operating at a fire with multiple fatalities and will not be responding. What would be a correct action to take?

(Sec. 5.3, 5.3.1, 5.3.2, 5.3.3, 5.3.4)

 

(A) Skim the surface of the water containing the flammable liquid with a clean, used one gallon
metal paint can.

(B) Use a clean glass jar with a loosely fitting lid.

(C) Place the evidence in a new, heavy gauge plastic bag and tie it closed. Then place that bag
into another new, heavy gauge plastic bag and tie that bag closed.
 

D) Ask the IC if the Photo Unit is responding. If the IC responds that they are, label the
evidence prior to the Photo Units arrival so the pictures can be used to accurately portray the
evidence.
 

C

NEW PAINT CAN

TIGHTLY FITTING LID

NEVER LABEL EVIDENCE PRIOR TO PHOTOS

8. After the fire has been knocked down, and secondary searches are in progress, the IC asks
you via HT if you can determine the point of origin. You notice several glass objects that have
been affected by the fire. Which thought is correct? (Sec. 6.7.2, 6.7.3)


(A) Small crazing of the glass indicates remoteness from the point of origin and/or a relatively slow heat build up.


(B) Large crazing means intense and rapid heat build up and will be found closer to the point of
origin.


(C) Checkering of glass (half moon effects or marks) usually results from water being applied
to heated glass.


(D) Checkering of glass indicates the window was broken prior to firefighters operating at the
fire.
 

C

Glass objects used as indicators to help locate the point of origin.

Crazing of glass (cracking due to heat).

♦ Small crazing means intense and rapid heat build up and will be found closer
to the point of origin.
Large crazing indicates remoteness from the point of origin and/or a relatively
slow heat build up.
♦ Checkering of glass (half moon effects or marks) usually results from water
being applied to heated glass This indicates the window was still in place
when the firefighters operated at the fire.

9. Smoke stains and depth of charring may be used as indicators to help locate the point of
origin. An incorrect statement concerning these indicators can be found in which choice?
(Sec. 6.7.2, 6.8)


(A) Heavy smoke stains, remote from the point of origin, usually indicate a slow fire build up.


(B) Light smoke stains usually indicate a slow build-up of the fire, little fire damage and are
found far from the point of origin.


(C) At 1400 Degrees Fahrenheit, wood structural members may bum at approximately one inch
every 45 minutes.


(D) Deepest char may be found at the point of origin. However, this is not always necessarily
so, since most intense heat and fire may be above the point of origin.


(E) Smaller blister type charring may indicate longer burning and hot fires.
 

B

Light smoke stains usually indicate a rapid build up of the fire, little fire damage and are found close to the point of origin.
