Answer :
Final answer:
Class K fire extinguishers are not intended for use on combustible metals like magnesium; this statement is false. Fires involving combustible metals need Class D extinguishers, as traditional extinguishers can exacerbate the situation. Proper knowledge of fire extinguisher types is crucial for safety.
Explanation:
Understanding Class K Fire Extinguishers
The statement regarding Class K fire extinguishers is False.
Class K fire extinguishers are specifically designed for fires that involve cooking oils and fats, not for combustible metals. In fact, combustible metals such as magnesium, sodium, lithium, and potassium require a different type of extinguisher known as Class D. This is because they can react violently with water and carbon dioxide, making standard fire extinguishers ineffective.
Why Class D is Needed
For instance, when magnesium burns, it produces a bright light and can ignite more vigorously if water or CO2 fire extinguishers are used. The reaction of magnesium with water produces hydrogen gas, which can exacerbate the fire. Therefore, the recommended methods for controlling magnesium fires include using dry powder extinguishers or sand, not Class K or those designed for other types of fires.
Conclusion
Thus, it is critical to use the appropriate fire extinguisher for the specific type of material involved in the fire, as improper measures can lead to dangerous situations.
