Types of Fire Extinguishers
Fire extinguishers are usually classified according to the types of fires they extinguish. So the classes, in reality, define the fires themselves rather than the extinguisher. The main classes are; Class A: This describes a fire caused by solid carbon-based combustibles. These are common things like paper, plastic, wood, and even clothes. You can use water, wet, and powder chemical suppressants to extinguish these fires. Class B: This class refers to fires caused by flammable liquids such as diesel, paraffin, petrol, and oil, except cooking oil. Dry chemical powders and CO2 extinguishers are best for extinguishing these kinds of fires, and you should not use water as it will spread the fire. Class C: This class of fires is caused by flammable gases like butane, methane, and propane. Like Class B, these fires are best extinguished by dry chemical powder and CO2 extinguishers. Class D: Class D fires involve burning metals. Combustible metals like aluminum, magnesium, potassium, and lithium. Class F: These are fires resulting from cooking fat and oil. Electric fires are not denoted by a letter but instead by an electric spark. They are also best extinguished by dry chemical powders.
What Makes Dry Chemical Powder Excellent at Fire Extinguishing
Like any other extinguisher, our dry powder extinguishers work by removing one or several of the four critical elements of a fire. The same four elements present in any fire are; fuel, heat, oxygen, and chain reaction. The dry chemical powder contains mono ammonium phosphate as its extinguishing agent. This chemical spreads easily over the fire, melting and covering it, thus putting it out and preventing re-ignition. Even with class B and C fires, it prevents the vapor’s escape, quickly extinguishing the fire. These extinguishing properties are defined as follows:
The Smothering Effect
This is what has been described above, the powder has a lower melting point, and when in contact with the flame, it forms a glassy cover on top of solid surfaces, cutting oxygen out in class A fires.
Cooling Effect
It is not one of the main reasons for dry chemical powder’s effectiveness. Still, it is necessary for all chemical powders to be heat-sensitive to make the substance chemically active, so it should swallow heat.
Chain Breaking Reaction
This effect is the primary way dry chemical powders can quickly extinguish classes BC and electrical fires. For combustion to continue, the free radicals have to keep reacting with each other. Powering the dry powder breaks and prevents this chain reaction extinguishing the fire.
Radiation Insulation
The dry chemical powder creates an insulating cloud between the fuel and the flame, which insulates, to an extent, the fuel from the heat coming from the flame. This further prevents the spreading of the fire.
Advantages of Dry Chemical Fire Extinguishers
ABC dry chemical powder extinguishersare versatile and can extinguish a wide range of fires, making them excellent for work and home environments. They are affordable and efficient compared to other options. They are portable and in varied sizes making storage and use easy in different settings. Powder fire extinguishers have wide area coverage offering more protection. They offer an effective shield against heat and other flame damages, protecting objects and structures around the fire.
