Fire Extinguisher Safety Trivia Exam: Quiz!

1. You should always keep an exit or other means of escape at your back when fighting a fire.

True

False

When fighting a fire, it is important to always have an exit or another means of escape at your back. This is because fires can quickly spread and become uncontrollable, putting your safety at risk. By positioning yourself with an exit behind you, you can ensure a quick and safe escape if the fire becomes too dangerous to handle. It is crucial to prioritize personal safety when dealing with fires, and having an exit strategy is a fundamental part of that.

2. An APW (water extinguisher) is safety is on an electrical fire?

True

False

An APW (water extinguisher) is not safe to use on an electrical fire. Water conducts electricity, so using a water extinguisher on an electrical fire could result in electric shock or spread the fire further. It is recommended to use a fire extinguisher specifically designed for electrical fires, such as a CO2 extinguisher or a dry chemical extinguisher.

3. As a general rule, you should not attempt to fight a fire that is spreading rapidly?

True

False

Fighting a fire that is spreading rapidly can be extremely dangerous and should be avoided. Rapidly spreading fires can quickly grow out of control, leading to potential harm to individuals attempting to fight the fire. It is best to prioritize personal safety and evacuate the area, while alerting the appropriate authorities to handle the situation with professional firefighting equipment and expertise.

4. Applying water rapidly to a flammable liquid fire will cause it to do what?

Go out.

Knock the flames down enough that you can escape.

Cause the fire to flare up uncontrollably.

Cause the flames to change colors.

5. Describe what the acronym "PASS" means

Pull, aim, squirt, squeeze.

Pull, arm, squeeze, sweep

Pull, aim, squeeze, sweep.

Pull, arm, sweep, swoosh.

The correct answer is "Pull, aim, squeeze, sweep." This acronym "PASS" is commonly used in fire safety training to remember the steps for using a fire extinguisher. "Pull" refers to pulling the pin to unlock the extinguisher, "aim" means aiming the nozzle at the base of the fire, "squeeze" is about squeezing the handle to release the extinguishing agent, and "sweep" indicates sweeping the nozzle from side to side to cover the fire with the agent. This sequence of actions is crucial for effectively and safely extinguishing a fire.

6. An example of two "Class B" fuels would be:

Brass and aluminum.

Cardboard and newspapers.

Grease and paint thinner.

A toaster and a circuit breaker.

The correct answer is Grease and paint thinner. This is because Class B fuels are flammable liquids or gases, and both grease and paint thinner fall under this category. Brass and aluminum are not fuels, but metals. Cardboard and newspapers are combustible materials, but they are not classified as Class B fuels. A toaster and a circuit breaker are not fuels at all.

Explanation

The correct answer is Grease and paint thinner. This is because Class B fuels are flammable liquids or gases, and both grease and paint thinner fall under this category. Brass and aluminum are not fuels, but metals. Cardboard and newspapers are combustible materials, but they are not classified as Class B fuels. A toaster and a circuit breaker are not fuels at all.

7. The three elements of the fire triangle are:

Oxygen, water and fuel.

Oxygen, fuel and a heat or ignition source.

Fuel, a catalyzer, and oxygen.

None of the above.

The correct answer is oxygen, fuel, and a heat or ignition source. These three elements are necessary for a fire to occur. Oxygen provides the necessary oxidizer, fuel provides the material that can be burned, and a heat or ignition source provides the initial energy to start the combustion process. Without any of these three elements, a fire cannot be sustained.

Without any of these three elements, a fire cannot be sustained.

8. A class C fire extinguisher is designed to be used on the following fires:

Wood and paper.

Magnesium or potassium.

Toasters and circuit breakers.

Vehicle engine fires.

A class C fire extinguisher is designed to be used on fires involving electrical equipment such as toasters and circuit breakers. This type of extinguisher contains non-conductive agents that can safely suppress the fire without conducting electricity and causing further damage or harm. It is important to use a class C fire extinguisher when dealing with electrical fires to ensure the safety of both individuals and the surrounding environment.

9. Which type of fire extinguisher has a large black plastic horn on the end of a flexible hose or short rigid pipe?

Air pressurized water. (APW)

Carbon dioxide. (CO2)

Dry chemical. (ABC)

All of the above.

The correct answer is Carbon dioxide (CO2) because it is the type of fire extinguisher that has a large black plastic horn on the end of a flexible hose or short rigid pipe. This horn is used to direct the flow of carbon dioxide onto the fire, suffocating it and extinguishing the flames.

Explanation

The correct answer is Carbon dioxide (CO2) because it is the type of fire extinguisher that has a large black plastic horn on the end of a flexible hose or short rigid pipe. This horn is used to direct the flow of carbon dioxide onto the fire, suffocating it and extinguishing the flames.

10. Carbon dioxide fire extinguishers are designed for which types of fuels?

Class B and C.

Classes A, B and C.

Class A and C.

Class D and A.

Carbon dioxide fire 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 electrical equipment. Carbon dioxide extinguishers work by displacing oxygen and smothering the fire, making them effective for these types of fires. They are not suitable for Class A fires, which involve ordinary combustible materials such as wood and paper, or Class D fires, which involve combustible metals.

11. ABC type dry chemical fire extinguishers extinguish the fire by cooling it down?

True

False

ABC type dry chemical fire extinguishers do not extinguish the fire by cooling it down. These extinguishers work by smothering the fire and interrupting the chemical reaction that sustains it. The dry chemical agent in these extinguishers forms a barrier between the fuel and oxygen, thus depriving the fire of one of its essential elements. This method of extinguishing a fire is known as chemical inhibition or oxygen displacement. Therefore, the correct answer is false.
