What is a Class B fire?

A Class B fire specifically refers to fires that involve flammable liquids and gases, such as gasoline, oils, and solvents. These materials can produce volatile vapors that ignite easily and lead to explosive fire scenarios. It is essential for individuals to recognize Class B fires because they require distinct firefighting methods compared to other classes of fires. For instance, water should not be used to extinguish a Class B fire, as it can spread the fire by causing the flammable liquids to float and disperse. Instead, extinguishing agents such as foam, dry chemical, or carbon dioxide are more effective and safe for combating these types of fires.

In a practical context, understanding the nature of Class B fires helps ensure proper fire prevention measures are implemented on ships and in various industries, where flammable liquids are commonly stored and used. Recognizing the specific characteristics of Class B fires also aids in the selection of appropriate firefighting equipment to mitigate risks effectively.
