1. 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.
2. 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
3. What dilution of ethylene oxide with water is required to effectively inhibit its
flammability?
Answer: 24: 1
4. 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
5. 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
6. 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.
7. 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.

, 8. 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.*
9. 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.*
10. 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.
11. 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.*
12. 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.*
