Question: 1 / 400

What materials are commonly involved in a Class D fire?

Wood, Plastic, Aluminum, Cotton

Aluminum, Magnesium, Titanium, Sodium

Class D fires involve combustible metals, which distinguishes them from other classes of fires that typically concern organic or liquid materials. The correct answer includes materials such as aluminum, magnesium, titanium, and sodium, all of which are classified as flammable metals. When these metals are exposed to heat or flame, they can ignite and burn at extremely high temperatures, making them particularly dangerous and difficult to extinguish.

Understanding the nature of Class D fires is crucial for effective fire response, as typical extinguishing agents like water may react with these metals in ways that can exacerbate the danger. Specialized extinguishing agents or dry powder extinguishers are often required to put out fires involving these materials safely.
