Which extinguishing agent is best for use on a magnesium fire?
AI Explanation
The correct answer is D) Sand.
Magnesium is an extremely reactive metal that can burn at very high temperatures. Water, CO2, and dry chemical extinguishers are not effective on magnesium fires, as they may actually worsen the fire. The best extinguishing agent for a magnesium fire is sand or another dry, inert material that can smother and isolate the burning metal from oxygen. Sand works by separating the magnesium from the air, cooling the metal, and creating a barrier to prevent further combustion. The other options would be ineffective or potentially dangerous when used on a magnesium fire.
