Top 5 Fire Types and How to Extinguish Them
Incidents where a fire spreads is not only dangerous for you and your building occupants, but can also cause serious damage to the facility. If a fire occurs, you should be equipped with the appropriate extinguishing products for all fire types, in addition to a strong fire barrier.
Here are the top 5 fire types and how to extinguish them:
1. Class A
This is the most basic form of how a fire spreads. Combustible or inflammable items such as wood, paper, plastic, textiles and etc., catch fire after being overheated. They continue to burn so long as the heat, fuel and oxygen last.
Water and foam is the best type of fire extinguisher for such fire spreads as it extracts the element of heat and oxygen from the burning elements. All you have to do is spray is it over the burning item.
2. Class B
Liquids like kerosene, petrol, alcohol, etc. are flammable in nature. This is because they have a low flashpoint that qualifies them as easy to burn items. These are exceptionally dangerous liquids to keep near your stove top because a trivial fire spark can easily ignite them, massively.
The best fire extinguishers to use on such a fire type include carbon dioxide extinguisher, dry chemical extinguisher and clean agents.
3. Class C
These fires involve electrical components/energized electrical equipment, such as appliances, motors and transformers. More commonly, we see electrical fires with overloaded surge protectors and faulty wiring in buildings.
The most befitting extinguishers for this fire type include carbon dioxide or dry chemical extinguishers.
4. Class D
Loose or powdered metals commonly found in kitchens such as potassium, sodium and etc. are highly inflammable.
For powdered metals only dry powder extinguishers are suggested as this type of fire has to be dealt more tactfully to avoid further displacing the powder and fire.
5. Class F
These are the general fires caused by the accumulation of oil, grease and spots on your stove top. By nature, these spills are prone to catching fire and there should be cleaned as soon as possible.
The only type of extinguisher that must be used on this fire type should be wet chemical extinguisher.
According to NFPA statistics, kitchen incidents were the leading cause of fires. A properly-functioning
fire barrier system is vital to keeping fires contained so they don’t spread.
