Why are there different colors or pictograms on extinguisher labels?

• A. To decorate the extinguisher.
• B. To quickly identify the intended fire classes and to distinguish between extinguishing agents.
• C. To indicate the model year.
• D. To show the last inspection date.

Answer: (B)

Colors and pictograms on extinguisher labels help you know at a glance which fires it can fight and which extinguishing agent is inside. In an emergency, this quick recognition lets you pick the right tool without reading through manuals, reducing the risk of using the wrong agent or making the fire worse. The label shows the fire classes the unit is suitable for—such as ordinary combustibles, flammable liquids, energized electrical equipment, metals, or cooking oils—and the pictograms or text indicate the agent (water, foam, dry chemical, CO2, wet chemical, etc.). A multi-class extinguisher will display several pictograms to show it covers more than one fire type. The color blocks help distinguish different agent families and classes at a glance, which is especially useful in smoky or chaotic environments. This labeling is about safety and proper use, not decoration, model year, or last inspection date.
