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? - correct 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? - correct 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? - correct 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? - correct answer If it is a loose fitting garment, such as a jacket or coat, you

22. Icy road conditions can be particularly hazardous for driving because - correct
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. - correct 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? - correct 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. - correct 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.**
26. What is the most important attribute a good driver has over someone with
marginal driving ability? - correct answer A good attitude.
28. Firefighters are responsible for preventing any unnecessary damage from
occurring to hoselines at the scene of a fire. Not only are they expensive to replace,
but damaged hoses can become ineffective in fighting a fire if they cannot remain
charged because of leaks or ruptures. Which of the following hose-care practices is
not recommended?
A. Avoid excessive dragging.
B. Don't allow vehicles to run over charged hoses.
C. Avoid laying hose over sharp or rough corners.
