Fires involving combustible metals and highly reactive flammables are classified as which type of fire?

• A. Class B Fires
• B. Class C Fires
• C. Class D Fires
• D. Class A Fires

Answer: (C)

Fires involving combustible metals and highly reactive flammables are classified as Class D Fires. This classification is significant because it denotes fires that require special handling and extinguishing techniques due to the unique characteristics of the materials involved.

Class D Fires typically involve metals such as magnesium, titanium, sodium, and potassium, which burn at extremely high temperatures and may react violently with water or common extinguishing agents. These types of fires are not effectively extinguished using traditional methods such as water or foam; instead, they often require dry powder agents specifically designed for metal fires to smother the flames and prevent reignition.

Understanding the nature of Class D Fires is crucial for safety and emergency response in environments where combustible metals are present, ensuring that appropriate fire suppression strategies are employed to effectively manage such incidents.
