Which of the following statements is true about fire extinguishers?

Rationale

When using the fire extinguisher the hose is aimed at the base of the fire.

Aiming the fire extinguisher hose at the base of the fire is crucial because this is where the fuel source is located. By targeting the base, you can effectively cut off the fire's oxygen supply and extinguish it more efficiently.

A (There is only one type of fire extinguisher and it can be used for any type of fire.) YOUR ANSWER

This statement is incorrect. There are different types of fire extinguishers designed to combat specific classes of fires, such as Class A (ordinary combustibles), Class B (flammable liquids), and Class C (electrical fires). It is essential to use the correct type of extinguisher for the specific fire class to maximize effectiveness and safety.

B (To spray the extinguisher the handle is squeezed before pulling the safety pin.) YOUR ANSWER

This statement is incorrect. The correct procedure is to first pull the safety pin and then squeeze the handle to discharge the extinguishing agent. Pulling the safety pin helps prevent accidental discharge and allows you to operate the extinguisher quickly in case of a fire emergency.

C (Extinguishers are held upside down for proper emptying when spraying.) YOUR ANSWER

This statement is incorrect. Fire extinguishers should be held upright during use to ensure the proper discharge of the extinguishing agent. Tipping the extinguisher upside down can lead to ineffective operation and may cause the extinguisher to malfunction.

Conclusion

Proper use of a fire extinguisher is essential in firefighting situations to effectively control and extinguish fires. Aiming the hose at the base of the fire, using the correct type of extinguisher for the fire class, pulling the safety pin before squeezing the handle, and holding the extinguisher upright are all critical steps in ensuring the extinguisher functions correctly and helps mitigate fire hazards.
