A fire extinguisher could save your life if you know how to use it. When using a fire extinguisher, you must first decide whether or not it is safe for you to battle the fire and whether or not you are capable of extinguishing the fire completely. Evacuate the building immediately and call the fire department if you don’t think you can put out the fire on your own. Before we understand the process of operation of the fire extinguishers, let us understand what a fire extinguisher is and what the different types of fire extinguishers are.
Fire extinguishers can be used as portable equipment to put out small flames before firemen arrive. Fire extinguishers can be found at various locations, such as in buildings, factories, public transportation, and more. A location’s safety rules determine the types and numbers of extinguishers that are legally necessary.
Depending on the type of fire extinguisher, there are six variants available. They’re used for a variety of purposes.
Cylinders of extinguishing agents are filled with compressed air, gas, or chemicals that release gas when activated. To use the extinguisher, the user must first remove the safety lock and then pull the trigger or handle.
Using water extinguishers to put out Class A fires is one of the most cost-effective ways to do it. Water jets, water sprays, water with additives, and water mist or fog are the four main forms of water extinguishers. Water jet extinguishers cool and prevent re-ignition by squirting a jet of water at the flames. Using them on live electrical equipment is not recommended.
To put out a fire, water spray extinguishers spray an extremely fine mist of water droplets surrounded by impermeable air.
Water extinguishers with foaming chemicals added are known as water extinguishers with additives. Burning elements are more easily absorbed by the water because it loses their natural surface tension. For a fire extinguisher to be effective, it must have the same fire rating as a bigger water-only extinguisher.
Extinguishers using water mist or fog apply water in a mist or fog, and the droplets are smaller than those from water spray. Two factors that affect how quickly a water droplet evaporates are the droplet’s surface area and the droplet’s volume. As a tiny droplet weighs less, the cloud of water it creates is weaker.
A red label can be found on every water extinguisher.

For Class A and Class B fires, foam fire extinguishers can be used to put out the flames. Water jet extinguishers can only extinguish liquid fires like gasoline or fuel, whereas foam extinguishers can extinguish solid fires like wood and paper. Flame retardant foam can be used to extinguish liquid fires by preventing flammable vapour from reaching the air and therefore denying the fire fuel. Flowing liquid fires cannot be controlled with foam extinguishers.
There is a cream-coloured label on foam extinguishers.
As they work on Class A, B, and C fires, powder extinguishers make excellent all-purpose extinguishers. Even while they can be employed to put out electrical equipment fires, their cooling effect leaves the fire vulnerable to re-ignition. In addition to reducing visibility, powder extinguishers may potentially cause respiratory issues. However, unless there is no other option, they should not be used inside structures.
The label on powder extinguishers is blue.
In situations where there is a lot of electrical equipment, carbon dioxide extinguishers (CO2) are ideal since they are safe to use on fires involving electrical machinery. In contrast to foam extinguishers, carbon dioxide extinguishers don’t leave behind any residue. On class B fires, such as those that involve flammable liquids like paraffin or gasoline, they can also be employed. CO2 extinguishers function by suffocating the fire and shutting off the flow of air, thus putting out the flames.
Class F fires containing cooking oils and fats, such as lard, olive oil, sunflower oil, maize oil, and butter, can be put out with wet chemical extinguishers. When employed correctly, they can be immensely powerful. Using a soap-like solution, the wet chemical quickly extinguishes the fire, cools the burning oil, and seals the surface to prevent re-ignition. Class F fires, including fires caused by cooking oils and deep fat fryers, can be extinguished using this extinguisher.
Yellow is the colour of the label on wet chemical extinguishers.
Hot oil flames such as frying pans and small deep fat fryers can be extinguished with fire blankets. They can also be used to put out a fire started by a person’s clothing. To put out the fire, they suffocate it, blocking the oxygen supply that is feeding it.
You must know how to use a fire extinguisher in the event of a fire. In a fire emergency, being confident in how to use it is necessary. Make sure you have the correct sort of fire extinguisher on hand before you need to use one. Fire extinguishers should only be used by people who have been educated in their proper use.
It’s always best to seek outside assistance while trying to put out a fire on your own. A fire may get out of hand faster than you expect. Help on the way is a good idea.
Before approaching the fire, plan an evacuation route. No matter how dangerous it may be, let nothing stand between you and your evacuation route.
To use the PASS Method, one must first learn how.
