2. All portable fire extinguishers are suitable for use on any fire.

True

False

Not all portable fire extinguishers are suitable for use on any fire. Different types of fires require different types of extinguishing agents. For example, water extinguishers are effective on Class A fires (ordinary combustibles like wood and paper), but they should not be used on Class B (flammable liquids) or Class C (electrical) fires. Similarly, CO2 extinguishers are suitable for Class B and C fires, but not for Class A fires. Therefore, it is incorrect to say that all portable fire extinguishers are suitable for any fire.

3. A CO2 fire extinguisher may be easily recognized by the fact that it has a horn rather than a discharge hose.

True

False

A CO2 fire extinguisher can be easily recognized by the fact that it has a horn rather than a discharge hose. This is because CO2 fire extinguishers use carbon dioxide gas to extinguish fires, and the horn is designed to direct the gas towards the fire. The absence of a discharge hose is a distinguishing feature of CO2 fire extinguishers, as other types of fire extinguishers, such as water or foam extinguishers, typically have a hose for spraying the extinguishing agent. Therefore, the statement is true.

4. Of the three classes of fire, which class is designated for flammable liquids?

Class A

Class B

Class C

Class B is designated for flammable liquids. Class A is designated for ordinary combustibles such as wood and paper, while Class C is designated for electrical fires. Flammable liquids, such as gasoline and oil, require a specific class designation due to their unique properties and the specialized methods required to extinguish them safely.

9. What are the two most common types of fire extinguishers available at the plant?

Water (H2O)

Dry Chemical

Magnesium

Oxgen

CO2

Dry chemical and CO2 are the two most common types of fire extinguishers available at the plant. Dry chemical extinguishers are effective in suppressing fires involving flammable liquids, electrical equipment, and combustible materials. They work by smothering the fire and interrupting the chemical reaction. CO2 extinguishers, on the other hand, are suitable for fires involving flammable liquids and electrical equipment. They work by displacing oxygen, which helps to suffocate the fire. Both types of extinguishers are widely used in industrial settings due to their effectiveness and versatility in tackling various types of fires.

10. What are some key points concerning a fire door?

All of the above

A fire door must not be blocked to ensure that it can be easily accessed in case of a fire. It must also have a fusible link that melts and shuts the door in the event of a fire, preventing the spread of flames and smoke. Additionally, the fire door must be in good operating condition to effectively serve its purpose. Therefore, the correct answer is that a fire door must not be blocked, must have a fusible link that melts and shuts in case of fire, and must be in good operating condition.
