Addressing Different Styles of FireJuly 25, 2018 10:00 am
We all know that there are different types of fire and that you should use a different method to tackle each of them. However, there is a lot of misinformation about precisely what tactics you should use in each situation.
In this blog, we will go over some of the most common causes of fire in homes and buildings. We will discuss exactly what you should do if and when each of these take place.
Before we go any further, we should mention that you should always call the fire brigade at the earliest opportunity when you become aware of a blaze. Your safety should always come first, so leave it to the professionals.
We should also mention that we won’t be covering a class D fire, which concerns flammable metals, as they are somewhat niche and you are unlikely to come across them outside of specific industries.
How to Deal with a Class A Fire
Class A fires involve regular solid combustible materials such as wood, textiles, paper, and some plastics.
If you have a fire extinguisher on-hand, you can use either a water or foam version to address the fire.
If you do not have an extinguisher on-hand, then you can just use water to put it out. Find as large a vessel you can, such as a bucket or basin, and get as much water as you can on the base of the flame. Keep going until the fire is out entirely.
Remember, if the blaze is out of control or you aren’t making any progress when fighting it, leave the area as soon as possible.
How to Deal with a Class B Fire
Class B fires refer to blazes which are being fuelled by flammable liquids such as lighter fuel, kerosene, petrol or oils.
If you they are available nearby, a CO2, foam, or dry powder extinguisher is effective against flammable liquids.
The first thing to note when dealing with flammable liquids is that using water is not a good idea. Water will only throw the flaming liquids around, causing the blaze to spread incredibly quickly and to other parts of the room.
In order to tackle a class B fire, you have to cut off the oxygen to kill the fire. To achieve this, you need to smother it. Ideally, get a fireproof blanket and throw it over the blaze. If not, and if the fire is small enough, a regular blanket will do.
How to Deal with a Class C Fire
Class C fires have flammable gasses as a fuel, such as methane and butane.
The only extinguisher that will do any good in this situation is one filled with dry powder. No other form of extinguisher is applicable.
If you can, shut off the gas supply to the blaze. This will remove the fuel supply for the fire which, all going well, will eventually burn out. However, if you can’t cut off the supply, it might be time to get to safety and wait on the fire brigade to kill the blaze.
How to Deal with a Class E Fire
Class E fires involve electrical fires such as faulty computers, generators, or household items.
If you have a fire extinguisher available, dry powder or CO2 will do the job.
Like with flammable liquids, do not use water to tackle an electrical fire. Since water conducts electricity, throwing a bucket of water on top of the electrical equipment is not a good idea as it can give you a dangerous electrical shock.
Firstly, make sure that you turn off the power supply to the equipment. From here, it is a case of trying to cut off the oxygen supply once again. Preferably use a fireproof blanket to smother the blaze, alternatively use a regular blanket.
How to Deal with a Class F Fire
Class F fires involve cooking fats, oils, and greases. These are commonly referred to as ‘chip pan fires’.
To begin with, take note that these fires are incredibly dangerous. Do not use water, do not move the pan, and do your best to turn the heat off if the fire is on the hob.
Because these fats burn so hot, in comparison to other materials, you need to use wet chemical fire extinguishers. No other form of extinguisher will work.
However, it is unlikely that you will have one of these nearby. So, you guessed it; you need to cut off the oxygen supply. If you can, grab a frying pan and attempt to cover up and smother the blaze from oxygen.
If not, just try and turn the heat off and wait for the fire brigade to arrive.
Protect Yourself from Fire
The safest way to protect yourself from fire is to make sure that your home or commercial facility has all of the necessary fire safety precautions. At the heart of every good fire safety system is a fire alarm, and that is where we come in.
