    You will need to work in a corridor that is a fire escape route.  You must see that:

    • Your tools and equipment do not block the route

    • All doors into the corridor are locked

    • You only use spark-proof tools

    • You remove all fire escape signs before you start

    Correct Answer
    A. Your tools and equipment do not block the route
    Explanation
    In order to work in a corridor that serves as a fire escape route, it is crucial to ensure that tools and equipment do not obstruct the path. This is important to maintain a clear and accessible route for people to evacuate in case of a fire emergency. By keeping the corridor free from any obstructions, the safety of individuals using the fire escape route is prioritized.

    When using a carbon dioxide fire extinguisher, the nozzle gets:

    • Very heavy

    • Very hot

    • Warm

    • Very cold

    Correct Answer
    A. Very cold
    Explanation
    When using a carbon dioxide fire extinguisher, the nozzle gets very cold. This is because carbon dioxide is stored in the extinguisher as a pressurized gas, and when it is released through the nozzle, it expands rapidly. This expansion causes the gas to cool down significantly, leading to the nozzle becoming very cold to the touch. It is important to handle the nozzle with caution to avoid frostbite or injury due to the extreme cold temperature.

    This fire extinguisher contains: - ProProfs

    This fire extinguisher contains:

    • Water

    • Foam

    • Dry powder

    • Carbon dioxide

    Correct Answer
    A. Carbon dioxide
    Explanation
    This fire extinguisher contains carbon dioxide because carbon dioxide is commonly used as a fire suppressant. When carbon dioxide is released from the extinguisher, it displaces the oxygen around the fire, effectively smothering it and extinguishing the flames. Carbon dioxide is a suitable choice for certain types of fires, such as electrical fires, as it does not conduct electricity and is non-damaging to electrical equipment.

    This extinguisher must not be used on: - ProProfs

    This extinguisher must not be used on:

    • Electrical fires

    • Wood fires

    • Burning oil

    • Burning petrol

    Correct Answer
    A. Electrical fires
    Explanation
    This extinguisher must not be used on electrical fires because it contains water, which conducts electricity and can cause electric shock or spread the fire.

    A large fire has been reported.  You have not been trained to use fire extinguishers.  You should:

    • Put away all your tools and then go to the assembly point

    • Report to the site office and then go home

    • Go straight to the assembly point

    • Leave work for the day

    Correct Answer
    A. Go straight to the assembly point
    Explanation
    In the event of a large fire and lacking training to use fire extinguishers, it is important to prioritize personal safety and evacuate the area promptly. Going straight to the assembly point ensures that you are away from the immediate danger and can receive further instructions or assistance if needed. This option prioritizes the well-being of individuals and allows for a coordinated response to the fire situation.

    This type of fire extinguisher puts out a fire by: - ProProfs

    This type of fire extinguisher puts out a fire by:

    • Starving the fire of oxygen

    • Cooling the burning material

    • Increase the oxygen supply

    • Diluting the oxygen with another gas

    Correct Answer
    A. Cooling the burning material
    Explanation
    This type of fire extinguisher puts out a fire by cooling the burning material. When the extinguisher is sprayed onto the fire, it lowers the temperature of the burning material, which helps to slow down or stop the combustion process. By reducing the heat, the fire is deprived of the energy it needs to sustain itself, effectively extinguishing it.

      How does this type of extinguisher put out fires? - ProProfs

      How does this type of extinguisher put out fires?

    • It gets rid of the heat

    • It keeps out oxygen

    • It removes the fuel

    • It makes the fire wet

    Correct Answer
    A. It keeps out oxygen
    Explanation
    This type of extinguisher puts out fires by keeping out oxygen. Oxygen is one of the three elements required for a fire to burn, along with heat and fuel. By creating a barrier between the fire and the surrounding air, the extinguisher deprives the fire of the oxygen it needs to sustain itself. Without oxygen, the fire cannot continue to burn and is extinguished.

    A hot works permit lets you:

    • Work in hot weather

    • Carry out work that needs warm protective clothing

    • Carry out work that could start a fire

    • Light a bonfire

    Correct Answer
    A. Carry out work that could start a fire
    Explanation
    A hot works permit allows individuals to carry out work that has the potential to start a fire. This permit is necessary to ensure safety measures are in place to prevent fires and protect both workers and the surrounding environment. By obtaining a hot works permit, individuals are authorized to engage in activities such as welding, cutting, soldering, or any other work that involves the use of open flames or generates sparks or heat that could ignite flammable materials.

    This fire extinguisher contains: - ProProfs

    This fire extinguisher contains:

    • Foam

    • Carbon dioxide

    • Water

    • Dry powder

    Correct Answer
    A. Water
    Explanation
    The fire extinguisher contains water as one of its components. Water is commonly used in fire extinguishers as it can effectively cool down the fire and extinguish it by removing heat. It is particularly useful for fires involving ordinary combustible materials such as wood, paper, and cloth. Water works by reducing the temperature of the fire below its ignition point, thereby preventing the fire from spreading and causing further damage. However, it is important to note that water should not be used on fires involving flammable liquids or electrical equipment, as it can be ineffective or even dangerous in such situations.
