Fire is a devastating experience. It is important for each of us to know basic fire fighting procedures and techniques. When extinguishing a fire, the fire is divided into 5 classes. Each class is classified according to the fuel involved in the fire.
This classification was formulated to better understand how to effectively prevent and suppress each class. This setting also allows the selection of the right fire extinguisher for a particular fire to avoid unwanted side effects. For example, dry powder fire extinguishers are used for common flammable substances, flammable gasses or liquids, and electrical fires, whereas hospital fire safety training is only effective for fires caused by electricity.
Of the five main classifications, Class A is the most common. It is made of combustible materials such as paper and wood. This also includes fires of crops and their derivatives such as straw, cotton, linen, cardboard, wood and textiles. On the other hand, synthetic polymer flames absorb rubber and plastics.
Another way to prevent Class A fires is to use a fire extinguisher. Hydro Spray fire extinguishers are best suited for Class A fires. They contain special additives that reduce the surface tension of water and prevent the spread of fire.
Class A, B, and C fires, on the other hand, use dry powder extinguishers that are pressurized with nitrogen and filled with a specific powder. Foam fire extinguishers extinguish class A and B fires by forming a reactive layer on the extinguishing fluid.
