No matter if you’re residential or commercial, in a room with a potential fire hazard or not you need fire extinguishers. Fire extinguishers, however, aren’t all created the same – there are many different types of extinguishers, each with its own strengths and weaknesses.
To decide which one is right for you, you first need to know the different types of extinguisher. Fire extinguishers are usually classified according to the extinguishing agent, and the types of fire they can most effectively put out. In this article, we’ll help you find out which commercial fire extinguisher type is best for you in 2022. We will also run you through the facets of each.
The most common, most versatile fire extinguisher is known as the ABC extinguisher. The “ABC” is an acronym of jargon that is code for all the types of fire it can put out:
A: Solid combustible materials
B: flammable liquids
C: flammable gasses
This extinguisher sprays powder of monoammonium phosphate directly toward the fire, and is an excellent option for office buildings and homes. The ABC Extinguisher has a maximum range between five and twenty feet depending on the manufacturer, and a discharge duration of 8 to 25 seconds.
Carbon Dioxide Extinguishers
Carbon dioxide extinguishers shoot gaseous CO2 toward the fire, thereby depriving of oxygen and its ability to continue burning. CO2 extinguishers are typically used in spaces like the manufacturing sector, where there may be a high concentration of sensitive machinery or otherwise fragile materials around. It’s ideal for fires involving flammable liquids and electrical fires (up to 30 kV).
Kitchen Class K Extinguishers
Class K extinguishers deal primarily with class K flames – flames that erupt in a kitchen setting, often from grease fires that are not extinguishable with water. As any chef can tell you, mistakes can happen in the kitchen, and around high heat accidental spills can quickly turn into sizable fires. Class K fires are an everyday risk of those who work in the cooking sector, and proper kitchen fire preparedness is paramount.
While other extinguishers may be able to temporarily calm a class K fire, a class K extinguisher’s liquid extinguishing agent will better prevent it from reigniting. Class K fire extinguishers are required to be placed within 30 feet of any cooking line – a regulation more strict than the more common ABC extinguisher.
In environments that house highly expensive or fragile equipment, like server rooms, or places with sensitive or unstable materials, like laboratories. This is due to the fact that halon extinguishers leave zero chemical residue behind, leaving no meaningful trace after the fire is extinguished. While halon extinguishers are primarily used in commercial environments, you may also use them in places around your home or garage.
Pressurized Water Extinguishers
Fire extinguishers don’t always have to use fancy materials to be effective – for some fires, pressurized water will work just as well as anything else. Although pressurized water extinguishers are only effective on Class A flames, they are inexpensive to buy and maintain, and they leave no chemical residue when utilized.
BC Regular Extinguishers
Loaded with potassium or sodium bicarbonate, BC fire extinguishers are built for chemical and non-kitchen oil fires, chiefly types B and C fires. Comparable in operation to other types of fire extinguisher, the BC extinguisher can often be found in mechanical shops, in workshops, and other industrial businesses.
