What does a yellow label on a fire extinguisher typically indicate?

• A. It contains a Class B extinguishing agent
• B. It contains a Class D extinguishing agent
• C. It contains a Class A extinguishing agent
• D. It contains a Class C extinguishing agent

Answer: (B)

A yellow label on a fire extinguisher indicates that it contains a Class D extinguishing agent, which is specifically designed for use on fires involving combustible metals such as magnesium, sodium, and potassium. Class D fires require special agents that can effectively smother the fire and halt combustion, as traditional extinguishing agents may not work and can even exacerbate the fire. The use of a yellow label helps users quickly identify the extinguisher's capability in emergency situations, ensuring that the correct type of fire extinguisher is used. The other options correspond to different Classes of fire extinguishers that use various colors to denote their fire-fighting capabilities, making it clear that the yellow label is unique to Class D.
