Which letter and symbol identify the extinguisher for flammable liquid fires?

The identification of fire extinguishers is crucial for effective fire safety and response. The proper method for extinguishing flammable liquid fires involves using a fire extinguisher specifically designed for that class of fire, which is represented by the letter B. This notation is standardized to inform users quickly and accurately about which type of fire the extinguisher can combat.

A fire class categorized under the letter B includes flammable liquids such as gasoline, oil, and solvents. The associated symbol for this extinguisher category is a red square, which further helps to distinguish it from extinguishers meant for other types of fires. By recognizing this system of identification, individuals in emergency situations can make informed choices about which extinguisher to use, thereby increasing the chances of safely managing the fire.

Understanding these symbols and classifications is vital for anyone involved in contracting or construction, as it contributes to overall workplace safety and compliance with fire safety regulations.
