Training Quiz On Fire Extinguisher Types And Use! Trivia

Explanation
Gasoline is not an ordinary combustible because it is a highly flammable liquid. Unlike wood, cloth, and paper, which are common combustible materials that can burn easily, gasoline has a low flash point and can ignite with just a small spark or heat source. Due to its volatile nature, gasoline is classified as a hazardous material and requires special handling and storage precautions to prevent accidents and fires.

Explanation
A class B extinguisher works by blanketing the fuel. This means that when a class B extinguisher is used, it releases a substance that forms a layer over the fuel, cutting off the oxygen supply and smothering the fire. This helps to extinguish the fire and prevent it from spreading.

Explanation
A class C extinguisher is not limited to use on electrical fires only. It is designed to extinguish fires involving electrical equipment, but it can also be used on other types of fires such as flammable liquids or gases. Therefore, the statement that a class C extinguisher can only be used on an electrical fire is false.

Explanation
An extinguisher with a higher rating indicates that it is more effective at extinguishing fires. In this case, a 4A rated extinguisher is twice as effective as a 2A rated extinguisher. This means that it can extinguish a fire that is twice as large as the fire that a 2A rated extinguisher can handle. Therefore, the statement is true.

Explanation
The duration of discharge on a typical portable extinguisher is 5 to 30 seconds because portable extinguishers are designed to quickly release the extinguishing agent in order to suppress the fire. This short duration ensures that the extinguisher can be used efficiently and effectively to control the fire before it spreads further.

Explanation
The correct answer is "All of the above" because the statement includes three common types of fire extinguishers: water, dry chemical, and CO2. This means that all three types are considered common and are included in the answer.

Explanation
A 10 pound dry chemical extinguisher will typically discharge in 8-10 seconds. This means that it will release its contents within this time frame when used to put out a fire. This quick discharge time is important in order to effectively suppress the flames and prevent the fire from spreading further. It allows for a rapid response to fire emergencies and ensures that the extinguisher can be used efficiently in critical situations.

Explanation
In case of a burning odor or smoke, calling 911 first is the correct action to take. This is because a burning odor or smoke can indicate a fire or potential danger, and it is important to prioritize contacting emergency services to ensure a swift response and proper assistance. Calling 911 allows trained professionals to assess the situation, provide guidance, and dispatch the appropriate resources to address the emergency effectively.

Explanation
It is important to have your back to a clear exit when using a portable fire extinguisher because it allows you to have a quick and safe escape route in case the fire becomes uncontrollable or if the extinguisher fails to put out the fire. Having a clear exit behind you ensures that you can easily evacuate the area without getting trapped or blocked by the fire.

Explanation
The P.A.S.S. method stands for Pull the pin, Aim at the base of the fire, Squeeze the handle, and Sweep from side to side. This method is a recommended technique for effectively using a portable fire extinguisher. By pulling the pin, aiming at the base of the fire, squeezing the handle, and sweeping the extinguisher from side to side, individuals can maximize their chances of successfully extinguishing a fire. Therefore, the statement that the P.A.S.S. method should be utilized when operating a portable fire extinguisher is true.
