Answer :
Final answer:
The most effective extinguishing agents for a class Delta fire are dry powder extinguishers or Class D extinguishers designed for metal fires. Water and regular fire extinguishers may react violently with these fires. Specialized firefighting agents, like sand or graphite powder, can also be used effectively.
Explanation:
Class Delta fires involve combustible metals such as magnesium, titanium, and potassium. The most effective extinguishing agents for these fires are dry powder extinguishers or Class D extinguishers specifically designed for metal fires. The dry powder inside these extinguishers smothers the fire by forming a crust over the burning metal, cutting off the oxygen supply. It is important to note that water and regular fire extinguishers may react violently with combustible metals, making them ineffective and potentially dangerous to use.
In addition to dry powder extinguishers, some specialized firefighting agents, such as sand or graphite powder, can also be used effectively to put out class Delta fires.
