Asphyxiation robs the body of what?
Correct Answer
C. Oxygen
Explanation
Asphyxiation is a condition where the body is deprived of oxygen. Oxygen is essential for the body's cells to function properly and produce energy. Without oxygen, the body's organs, including the brain, cannot perform their normal functions, leading to severe consequences and potentially death. Asphyxiation can occur due to various reasons, such as suffocation, choking, or exposure to toxic gases, all of which prevent the body from receiving an adequate supply of oxygen.

Therefore, the statement "Class D fires are combustible metals" is true.
7.
Name one type of common sprinkler system?
Correct Answer
Wet Pipe
Dry Pipe
Explanation
Wet Pipe and Dry Pipe are both types of common sprinkler systems used for fire protection. Wet Pipe sprinkler systems have water constantly present in the pipes, allowing for immediate water discharge when a fire is detected. Dry Pipe sprinkler systems, on the other hand, are filled with pressurized air or nitrogen instead of water. When a fire is detected, the air is released, allowing the water to flow and extinguish the fire. Both systems are widely used in various settings to prevent and control fires.
8.
Avoiding the "electrical octopus" is not a good way of avoiding an electrical fire?
Correct Answer
B. False
Explanation
Avoiding the "electrical octopus" is not a good way of avoiding an electrical fire because an "electrical octopus" refers to a situation where multiple electrical devices are plugged into a single power outlet using extension cords or power strips, which can overload the circuit and increase the risk of a fire. Therefore, avoiding the "electrical octopus" by using proper electrical outlets and not overloading circuits is indeed a good way to prevent electrical fires.
9.
Class A fires are what type of combustible materials?
Correct Answer
E. All of the above
Explanation
Class A fires involve ordinary combustible materials such as paper, wood, rubber, and cloth. These materials are commonly found in homes, offices, and other everyday environments. When these materials catch fire, they produce glowing embers and flames. It is important to use the appropriate extinguishing methods, such as water or foam, to suppress and extinguish Class A fires effectively.
10.
Class C fires are flammable liquids?
Correct Answer
B. False
Explanation
Class C fires are not flammable liquids. Class C fires involve energized electrical equipment, such as appliances, wiring, circuit breakers, and outlets. These fires are caused by electrical faults or malfunctioning equipment. To extinguish a Class C fire, it is important to turn off the power source before using an appropriate extinguishing agent, such as a dry chemical or carbon dioxide fire extinguisher.
11.
Name the three components needed to cause a fire?
Correct Answer
Fuel
Heat
Oxygen
Explanation
The three components needed to cause a fire are fuel, heat, and oxygen. Fuel refers to any material that can burn, providing the necessary energy for the fire. Heat is required to raise the temperature of the fuel to its ignition point. Oxygen is necessary to support the chemical reaction called combustion, which sustains the fire by providing the necessary oxygen molecules for the reaction to occur. Without any of these three components, a fire cannot start or continue burning.
12.
Mercaptan is manufactured into natural gas to give the gas what type of smell?
Correct Answer
A. Rotten egg smell
Explanation
Mercaptan is manufactured into natural gas to give it a rotten egg smell. This is done as a safety measure to help detect gas leaks. Mercaptan is a sulfur compound that has a distinctive odor similar to that of rotten eggs. By adding this smell to natural gas, it becomes easier for people to identify if there is a gas leak, as the odor is highly noticeable and unpleasant. This helps to prevent accidents and ensure the safety of individuals using natural gas.
13.
What type of special hazards is indicated on the hazard diamond below.
Correct Answer
C. Radioactive Properties
Explanation
The correct answer is "Radioactive Properties" because the hazard diamond indicates that the substance in question has the potential to emit harmful radiation. This can pose a significant health risk to individuals who come into contact with the substance, as exposure to radiation can cause various adverse effects, including radiation sickness, genetic damage, and an increased risk of developing cancer. It is important to handle and store radioactive materials with great care and follow appropriate safety protocols to minimize the risk of exposure.
14.
The "A" stands for what in the acronym P.A.S.S?
Correct Answer
Aim
Aim at the base of the fire
Explanation
The correct answer is "Aim". In the acronym P.A.S.S, "Aim" refers to the first step in using a fire extinguisher. When faced with a fire, it is important to aim the nozzle or hose of the fire extinguisher at the base of the fire. This ensures that the extinguishing agent is directed at the source of the fire, effectively suppressing it. By aiming at the base of the fire, one can cut off the oxygen supply and prevent the fire from spreading further.
