How can you identify a Type B extinguisher?

A Type B extinguisher is specifically designed to combat flammable liquids and gases, such as gasoline, oil, and solvents. The correct identification feature for a Type B extinguisher is the letter "B" clearly displayed within a flame icon on a red background. This design not only helps users easily recognize the extinguisher's intended purpose but also adheres to safety standards for fire equipment labeling.

The use of a red label is significant because red is universally associated with fire safety, making it intuitive for individuals to understand its application in emergency situations. The flame icon further emphasizes that this extinguisher is suitable for fires involving flammable liquids.

In contrast, other labeling options, such as green, blue, or yellow, do not correlate with the identification of Type B extinguishers and could lead to confusion in an emergency. Therefore, recognizing the specific markings of Type B extinguishers is crucial for effective fire response and safety.
