What color shape is used for indicating a Class B fire?

The indication of a Class B fire, which involves flammable liquids and gases, is represented by a red square. This color and shape are part of a standardized system used to easily identify types of fires and the appropriate extinguishing agents. The red square signals urgency and danger, as Class B fires can be particularly hazardous due to the rapid spread of flames fueled by liquids like gasoline or oils.

The significance of the square shape is that it clearly distinguishes Class B fires from those of other classifications, which are assigned different symbols. This helps in quickly assessing the situation and taking the right action, such as using foam or dry chemical extinguishers designed for this type of fire. By understanding this symbol, firefighters and those trained in fire safety can effectively communicate and respond to potential fire emergencies.
