How can extinguishers suitable for class D fires be identified?

Extinguishers suitable for Class D fires, which involve combustible metals like magnesium, titanium, and sodium, are specifically identified by the presence of a yellow star emblem that contains the letter "D." This distinct marking helps firefighters and the public quickly recognize that the extinguisher is designed for use on these types of fires, where the application of water or standard extinguishing agents would be ineffective and potentially dangerous.

The yellow star signifies the special agent used in Class D extinguishers, such as dry powder, which smothers the combustion and prevents oxygen from reaching the burning metal. This identification is crucial for ensuring the safe and effective use of extinguishers in emergency situations involving metal fires.

Understanding the importance of this symbol allows firefighters and safety personnel to quickly assess the appropriate equipment needed for different types of fires, helping to prevent accidents and ensuring efficient firefighting efforts.
