LATEST ACTUAL EXAM
Which of the following was not suggested for personnel protection with regard to
dealing with the chemical in question?
A. Keep upwind of the chemical.
B. Wear self-contained breathing apparatus.
C. Avoid bodily contact with the chemical.
D. Any chemical that may inadvertently contact the body should be washed off with
large amounts of alcohol. - ANSWER: D. Any chemical that may inadvertently contact
the body should be washed off with large amounts of alcohol.
If a container of ethylene oxide has been subjected to fire for a prolonged period of
time, what is the recommended distance for safe evacuation? - ANSWER: 5,000 feet
What dilution of ethylene oxide with water is required to effectively inhibit its
flammability? - ANSWER: 24: 1
Once ethylene oxide becomes contaminated, what kind of chemical process may
occur that can generate enough heat and pressure to rupture its containment? -
ANSWER: Polymerization
13. Which of the following choices is not recognized as a symptom stemming from
ethylene oxide vapor exposure?
A. Eye irritation
B. Skin irritation or burns
C. Irritation of the respiratory system
D. Loss of muscular function - ANSWER: C. Irritation of the respiratory system
16. Firefighters often apply a hose stream to the side of a building that is in close
proximity to a fire. What is the primary reason for conducting such an operation? -
ANSWER: Radiant heat given off by the neighboring fire may adversely affect the
nearest wall. Without the coolant effect of the hose stream, enough heat may be
absorbed by an exposed surface to cause ignition and create a separate blaze.
17. Frequently, people use an octopus wall outlet connection to maximize the
number of appliances that can be plugged into a single outlet. What would this be
considered? - ANSWER: Unsafe, because the excessive amount of current drawn
,through the outlet may exceed what it is designed to handle. This may set the stage
for wires to overheat or a short circuit to occur, thus causing a fire within the
partition.
18. What is the greatest danger aspect for someone using an aluminum ladder to
install or realign a rooftop antenna? - ANSWER: A potential electrical shock hazard is
possible when in the vicinity of power lines.
**Any kind of metal ladder poses an electrical hazard if it comes into contact with an
energized power line. Aluminum is a superb conductor. Choices A and B are
incorrect. Choice D refers to a problem associated with aluminum ladders. However,
it is not considered a greater danger than the prospect of electrocution.**
19. In the process of fighting a fire, your superior officer directs you to perform a
different part of the operation. If, because of the noise and commotion you do not
fully hear or comprehend what was said, what should you do? - ANSWER: Ask your
commanding officer to repeat the instruction.
**Problems that occur at the fire scene that hamper the efficiency of how a fire is
handled are normally attributed to poor communication among firefighters. If a
direction is not fully comprehended or clearly heard, it is better to have it repeated
than to undertake action on your own initiative. Effective teamwork is imperative for
any kind of operation to be conducted efficiently. The other choices run counter to
this concept.**
21. If someone's clothing were to catch on fire, what would be an appropriate thing
to do? - ANSWER: If it is a loose fitting garment, such as a jacket or coat, you should
attempt to strip it off.
Wrap a blanket or something similar around the victim to smother the flames.
Get the victim to drop to the ground and roll slowly.
22. Icy road conditions can be particularly hazardous for driving because - ANSWER:
Friction between the tires and road is minimized.
**Brakes, contrary to popular thought, are not directly responsible for stopping a
vehicle. Instead, they retard the motion of the wheels. Consequently, friction
develops between the tire and the road which is directly responsible for a vehicle
coming to a complete stop.**
23. According to the National Safety Council, each year twenty times more deaths
within the United States are caused by fires than by tornadoes, floods, earthquakes,
and hurricanes combined. What can we deduce from this statement?
A. Fires are more lethal by comparison.
, B. Tornadoes, floods, earthquakes, and hurricanes are taken for granted by most
people.
C. People are better able to cope with natural weather phenomena than fire.
D. Statistically there are many more fires than natural weather or geophysical
disasters. This, combined with public apathy and a lack of education about fire, is the
probable reason for the high fatality rate. - ANSWER: D. Statistically there are many
more fires than natural weather or geophysical disasters. This, combined with public
apathy and a lack of education about fire, is the probable reason for the high fatality
rate.
**When the destructive capabilities of fire are compared to those of tornadoes,
hurricanes, earthquakes, and floods, it is a misconception to think that fire is the
worst. In fact, the destructive energy of the other phenomenon discussed is
significantly greater. Additionally, fire prevention and education are taken for
granted by most people, thus leading to preventable accidents and consequent
fatalities.**
24. When mechanical ventilation is required to help purge heat and smoke from a
burning building, which of the following should be avoided? - ANSWER: Placing the
exhaust fan, if possible, in the same direction that the prevailing winds are coming
from.
**The vented exhaust is being directed against a prevailing wind. This is neither
efficient nor desired because the vented gases could be inadvertently recirculated
into the building. The best idea is to use wind to your advantage, not have it work
against you.**
27. In your judgment, what is the best reason for fire hoses to be removed and
reloaded on an apparatus at least once every 30 days?
A. Hose tends to get brittle with little use.
B. Water trapped within a hose after use can stagnate and deteriorate the lining.
C. It reduces the possibility of bends becoming permanently set at certain points in
the hoseline.
D. It is just another menial job to keep firefighters constantly busy. - ANSWER: C. It
reduces the possibility of bends becoming permanently set at certain points in the
hoseline.
**It is a fact that hose lines left unused for long periods of time deteriorate more
quickly than hoses that are frequently used. Unloading hose at least once a month
eliminates the problem of bends becoming permanently set in the lining. Once
bends happen, hoses can become weak at the bend points and are more prone to
leakage or rupture.**
