Which label color is used for a Dry Powder extinguisher?

• A. Blue labelled
• B. Red labelled
• C. Black labelled
• D. Yellow labelled

Answer: (A)

Color labeling on extinguishers helps you identify the right type at a glance. Dry powder extinguishers use blue labels, signaling they are versatile for A, B, and C class fires. They work by coating the fuel and interrupting the chemical reactions of the flame, making them effective on common combustibles, flammable liquids, and gases. They can also be used on electrical fires when the equipment is de-energized, though the residue can be messy and may damage delicate electronics. The blue label is chosen to stand out and stay consistent so responders can grab the right unit quickly. Other colors indicate different extinguishing agents—for example, CO2 is typically indicated with a black label, and wet chemical with yellow—so those choices would not identify a dry powder extinguisher.
