INR 1, What Is A Class B Fire? Causes, Hazards & Fire Safety Tips

Class B fires are among the most dangerous types of fires because they involve flammable liquids and combustible substances such as petrol, diesel, oil, paint, alcohol, grease, solvents, and chemicals. These fires can spread rapidly and produce intense heat and smoke, making them difficult to control without the proper firefighting equipment. Understanding what causes a Class B fire and how to prevent it is essential for improving fire safety in homes, industries, warehouses, fuel stations, workshops, and commercial spaces.

Unlike ordinary fires involving wood or paper, water should not be used on Class B fires because it can spread the burning liquid and make the situation worse. Specialized fire extinguishers such as foam, CO2, or dry chemical powder extinguishers are recommended for controlling these fires safely and effectively. Common causes of Class B fires include fuel leaks, chemical spills, electrical sparks, overheating equipment, smoking near flammable materials, and improper storage of combustible liquids.

Proper fire safety measures such as safe storage practices, regular inspections, employee training, and installing reliable fire protection systems can significantly reduce fire risks.
