Some common types of fire extinguishers include AFFF agent (Aqueous Film Forming Foam) – used on class A fires such as wood, paper, or fabric. Color: Characteristics of a fire such as its shape, color, and intensity can allow for the identification of the type of fuel (wood or coal) being consumed.Ī wide variety of substances are used to extinguish different kinds of fires, from simple fuels like wood and paper to the more complex ones like petrol and other flammable liquids. These three characteristics are briefly described in this section. Class K fire involves electrical equipment not associated with the generation, transmission, or distribution of electricity.įire can be distinguished from other light sources primarily by color, pattern, and movement. Using these classifications allows firefighters to know what equipment they will need to control the fire. Fires are classified into four main levels: A, B, C, and D. Blue flames indicate that something with high carbon content has caught on fire - such as oil or wax - but it does not necessarily mean that the flame has spread to other materials or will become more intense.įire classification is the process of determining the fire level, which is based on understanding the temperature and fuel in a given area. Red, orange, and yellow flames indicate that there are carbon compounds burning in the organic material. The key to identifying the difference between a fire and smoke is flame color. When this happens, fire can spread and become more intense. How to distinguish fire?įire is a process that occurs when a material undergoes a chemical change due to heat. The five common methods of extinguishing fires are cooling with water for Class A fires, smothering with a chemical for Class B fires, starving (cutting off the supply of oxygen) for class C fires, breaking the chain reaction of fire for Class D fires, and Chemical fire extinguishers for Class K fires. Keep your home or business safe by keeping on hand the right types of equipment that are designed to put out specific types of fires. We’ll discuss the various kinds of fires that pop up and how to precisely put them out.įires are classed into certain categories and are based on the fire’s fuel source. Did you know, however, that there are at least five different types of fires? These classes of fires require specific handling to squash the flames. Fire is fire – and it needs to be extinguished to preserve the safety of the environment.
