Questions and Answers
  • 1. 

    An example of two “Class B” fuels would be: 

    • A.

      Cardboard, newspapers

    • B.

      Lamp, hot plate

    • C.

      Grease, paint thinner

    Correct Answer
    C. Grease, paint thinner
    Explanation
    An example of two "Class B" fuels would be grease and paint thinner. Class B fuels are flammable liquids, such as gasoline, oil, and solvents. Grease and paint thinner fall under this category as they have the potential to ignite and burn easily.

  • 2. 

    An APW (water extinguisher) is safe to use on an electrical fire. 

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    An APW (water extinguisher) is not safe to use on an electrical fire because water conducts electricity and can potentially worsen the situation or cause electrocution. Using a water extinguisher on an electrical fire can lead to further damage and increase the risk of harm to individuals attempting to extinguish the fire. It is important to use a fire extinguisher specifically designed for electrical fires, such as a CO2 extinguisher, to safely put out the fire without the risk of electrical shock.

    Rate this question:

  • 3. 

    Carbon Dioxide extinguishers are designed for which types of fuels? 

    • A.

      Class B and C

    • B.

      Class A, B and C

    • C.

      Class A and C

    • D.

      Class A and B

    Correct Answer
    A. Class B and C
    Explanation
    Carbon Dioxide extinguishers are designed for Class B and C fires. Class B fires involve flammable liquids such as gasoline, oil, and grease, while Class C fires involve energized electrical equipment. Carbon Dioxide extinguishers are effective for these types of fires because they displace oxygen, smothering the fire and preventing it from spreading. They are not suitable for Class A fires, which involve ordinary combustible materials like wood and paper, as carbon dioxide does not have the cooling or soaking properties needed to extinguish these fires.

    Rate this question:

  • 4. 

    Which type of extinguisher has a hard horn on the end of a flexible hose or metal arm? 

    • A.

      APW (air-pressurized water)

    • B.

      CO2 (carbon dioxide)

    • C.

      ABC (dry chemical)

    Correct Answer
    B. CO2 (carbon dioxide)
    Explanation
    A CO2 (carbon dioxide) extinguisher has a hard horn on the end of a flexible hose or metal arm. This design allows for easy and precise targeting of the fire. The horn helps to direct the flow of carbon dioxide towards the base of the fire, suffocating it by displacing the oxygen. The flexibility of the hose or arm also allows for better maneuverability in tight spaces.

    As a general rule, you should not attempt to fight a fire if it is spreading rapidly.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    It is generally advised not to attempt to fight a fire if it is spreading rapidly because it can quickly become uncontrollable and dangerous. Rapidly spreading fires can produce intense heat, smoke, and flames, making it difficult for individuals to extinguish the fire effectively and safely. In such situations, it is recommended to evacuate the area and call emergency services for professional assistance.

    Rate this question:

  • 6. 

    ABC fire extinguishers extinguish the fire by cooling it down.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    ABC fire extinguishers do not extinguish the fire by cooling it down. Instead, they extinguish the fire by smothering it and interrupting the chemical reaction that sustains the fire. ABC fire extinguishers contain a dry chemical agent that can put out fires involving ordinary combustible materials (Class A), flammable liquids (Class B), and energized electrical equipment (Class C). Therefore, the correct answer is False.

    Rate this question:

  • 7. 

    Water will not extinguish most flammable liquid fires.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Water will not extinguish most flammable liquid fires because water and flammable liquids do not mix. When water is poured onto a liquid fire, it can cause the flammable liquid to spread, leading to a larger fire. Additionally, water can evaporate quickly when exposed to high temperatures, which means it may not have enough time to cool down the fire and extinguish it effectively. Therefore, using water to extinguish most flammable liquid fires is not recommended.

  • 8. 

    You should always keep an exit or means of escape at your back when trying to fight a fire. ​​​​​​​

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Keeping an exit or means of escape at your back when fighting a fire is important for personal safety. This ensures that if the fire becomes uncontrollable or dangerous, you have a clear path to escape without being trapped. It allows you to quickly retreat and evacuate the area if necessary, minimizing the risk of injury or harm. By having an exit or means of escape at your back, you can maintain situational awareness and make informed decisions during a fire emergency.

    Rate this question:

  • 9. 

    The three elements of the fire triangle are: 

    • A.

      Water, a heat source, and fuel

    • B.

      Oxygen, water, and fuel

    • C.

      Oxygen, fuel, and a heat source

    • D.

      Fuel, oxygen, and earth

    Correct Answer
    C. Oxygen, fuel, and a heat source
    Explanation
    The three elements of the fire triangle are oxygen, fuel, and a heat source. Oxygen is necessary for combustion to occur, fuel provides the material to burn, and a heat source is required to initiate and sustain the fire. Without any of these three elements, a fire cannot start or continue to burn.

    Rate this question:

  • 10. 

    Do you know where the nearest fire extinguisher is in your work area?

    • A.

      Yes

    • B.

      No

    Correct Answer
    A. Yes
    Explanation
    The given answer suggests that the person knows the location of the nearest fire extinguisher in their work area. This implies that they are aware of the safety measures and have been trained on the location and usage of fire extinguishers. Being knowledgeable about the nearest fire extinguisher is crucial in case of a fire emergency, as it allows for a quick response to extinguish the fire and prevent further damage or harm.
