70% to pass

If a powdered aluminum fire is being fought, the correct extinguishing agent would be _______________.

A steam
B water fog
C CO2
D dry powder
AI Explanation

The correct answer is D) dry powder. For a powdered aluminum fire, a dry powder extinguishing agent is the correct choice. Dry powder extinguishers contain a special dry chemical that can effectively smother and extinguish metal fires, including those involving powdered aluminum. Water, CO2, and steam are not effective against this type of fire and could potentially make it worse. Dry powder extinguishers are specifically designed and required for fighting combustible metal fires to prevent further reaction and spread of the fire.
