When a fire grows too big, it’s too late. The firefighter is the main person responsible for saving lives. A second’s hesitation can inflict lethal damage to someone’s life. So, firefighting becomes the most authentic skill worth learning. Not knowing what to do when a fire breaks out can make things more complicated. One can find a fire anywhere and at any moment.
In India, a fire-related incident is reported every three minutes, with a lot of them proving fatal. However, many of these can be prevented with proper safety knowledge.
Quite a few things, such as the use of candles, electric heaters, lamps, fireplaces or other flammable articles, can result in it. When such a thing happens, a fire extinguisher is definitely the best option to put out the fire, mainly before it is beyond control.
Still, the question of how to use a fire extinguisher remains. Now, with instructions on the first-time use of a fire extinguisher being muddled, let’s discuss thoroughly how to use an extinguisher of each type correctly, and how a fire extinguisher works in case of each type, so that there’s no more confusion.
Class A fires containing solid combustible items such as wood, paper and textiles call for traditional water fire extinguishers. Modern water mist extinguishers containing de-ionised water can also be used on B, C and electric fires.
Before learning how to use a fire extinguisher, please learn that an extinguisher should only be used to combat minor flames. Should the fire seize hold, avoid fighting; instead, exit right away and notify others of the fire; then, contact the fire and rescue department. If you approach the fire, be sure to follow the guidelines below and keep at a safe distance:
On a fire involving flammable liquids (Class B) and solid combustibles (Class A), foam fire extinguishers are the most effective and safest extinguishers to use. Usually, these are quite serious fires—that is, the burning of liquids including petrol, diesel, paints, oil, solvents, spirits, and a great deal more besides.
The special power of the foam comes in handy because it is the vapour that leaves the liquid, rather than the liquid which burns.
Apart from extinguishing the flames like water, it forms a blanket on the surface of the burning liquid to provide a barrier separating the vapour from the air. This smothers the fire and quiesces the burning process. But how do you operate this fire extinguisher?
CO2 fire extinguishers spew carbon dioxide gas. The extinguisher stores this as a liquid, and when the handle is squeezed, pressure creates the gas.
CO2 fire extinguishers can be a bit tricky when it comes to chip pan fires. One issue is that the CO2 disperses quickly, which can actually make the fire spread to surrounding areas instead of putting it out effectively. Plus, unlike water or foam extinguishers that help cool the burning material, CO2 doesn’t provide that cooling effect. That’s why they’re not the best choice for dealing with solid fires.
On the contrary, a carbon dioxide extinguisher is useful because it releases carbon dioxide into the fire as a substitute for oxygen, thus initiating the process of extinguishing the fire. However, how to operate a fire extinguisher like this one?
If you’re wondering which extinguisher to use on a burning chip pan, a wet chemical fire extinguisher provides the solution. Any facility with a professional kitchen or deep fryer should, in fact, have a wet chemical fire extinguisher. But how does the fire extinguisher work?
Potassium forms the “chemical” component of wet chemical fire extinguishers.
Sprayed as a fine mist, gently so as not to distribute the burning oil or fat, these react to produce a soapy film on the surface of the substance on fire.
This smothers the fire, and the mist has cooling properties as well. But how do you use a fire extinguisher like this?
Wet chemical fire extinguishers should be handled with great care in order not to cause the burning fat or oil to splash into areas close by. By following these steps, you will be able to put out a fire with a wet chemical fire extinguisher effectively.
Almost every type of fire can be extinguished with standard dry powder fire extinguishers, which are incredibly adaptable. They are not advised, meanwhile, for usage in enclosed areas. Their ability to extinguish class A, B, and C types of flames also makes them known as ABC fire extinguishers. Their dry nature makes them usable for electrical fires.
As for how the fire extinguisher works, dry powder fire extinguishers separate the fuel from the oxygen source and smother fires.
Re-ignition is likely as they do not cool the flames.
Knowing how to use a fire extinguisher is of paramount significance, as it can save lives. For example, many types of fire extinguishers are available.
There is always a safety seal on all types of fire extinguishers; remove that first, otherwise the extinguishers won’t work. Now that you know how to use a fire extinguisher, check out awesome deals at L&T-SuFin for the best quality fire extinguishers.
An ABC fire extinguisher, also known as a dry powder one, is usually used against all three groups of fires (A, B, and C). It can also be used to put out electrical fires because it does not conduct electricity due to its dry powder.
In fire classes, a Class B fire denotes a blaze fueled by such things as flammable solid/liquid/gas- petroleum greases, tars, oils, paint (which is oil-based), solvents, lacquers or alcohols in flammable liquids or flammable gases.
