Is a Class D fire extinguisher suitable for putting out burning wood?

Answer: B — False

A Class D fire extinguisher is specifically designed to combat fires involving combustible metals, such as magnesium, titanium, and sodium, rather than common materials like wood. The effectiveness of a Class D extinguisher is due to its specialized agents that can smother or extinguish these specific types of fires. Using a Class D extinguisher on a wood fire would be inappropriate and potentially dangerous, as the materials involved in wood combustion require a different approach. Typically, a Class A fire extinguisher is recommended for wood and ordinary combustibles, as it utilizes water or foam to effectively cool and extinguish such fires. Therefore, stating that a Class D fire extinguisher is not suitable for burning wood is accurate and highlights the importance of using the correct type of extinguisher for specific fire situations.
