Answer :
Final answer:
The correct answer is b) False. Class K fire extinguishers are not meant for combustible metals like magnesium, sodium, lithium, or potassium.
Explanation:
The correct answer is b) False. Class K fire extinguishers are specifically designed for combustible kitchen fires involving fats, greases, and oils, not for combustible metals like magnesium, sodium, lithium, or potassium.
For example, magnesium reacts with water and carbon dioxide, so using water or a CO₂ fire extinguisher would not be effective in extinguishing a magnesium fire.
It is important to use the correct type of fire extinguisher based on the nature of the fire to ensure safety and effective extinguishment.
