All about Fire Extinguishers in Nepal

Fire has always been important for humans, be it for cooking or warming ourselves or anything that requires heat. Back when it was first discovered, we used to rely on natural fires to fulfill our needs. However, we have moved past this and can now control fire. Even better than this, we don't even need fire anymore; we have electricity to do virtually everything a fire does. 

However, we have not entirely gotten rid of the fire. The thing about fire is that it can start anywhere as long as some conditions are met. All you need is a flammable substance and some heat. This is where the problem with fire lies - it doesn't need human intervention to start. Forest fires are natural disasters that are relatively common in dry places. 

Although humans are safe from fire hazards for the majority, we still are not immune nor completely independent. Some of the most common causes are electrical devices. A single spark of electricity near a flammable object is enough to burn the entire house down. This is where fire extinguishers come into play. But what are they?

What are fire extinguishers?

Fire Extinguishers Nepal

As its name suggests, fire extinguishers are devices that put an end to or destroy fire. This is the general definition of a fire extinguisher. It is simply a device you use to put out a fire in case of an emergency, i.e. a fire safety measure. If you have visited any large commercial buildings, you may have noticed a red canister with a hose attached at the top and a small bulb like thing on the ceiling. This is a fire extinguisher and fire alarm system

You aim this device at the fire and pull the trigger to kill the fire. It's that simple! It is among the most effective ways to save yourself from a small fire. This is why you must have a fire extinguisher at home. Although it can be a bit expensive for regular people, the investment will be worth every coin you spend. 

That said, have you ever wondered how a fire extinguisher works?

How does a fire extinguisher work?

Fire Extinguishers Nepal

Fire extinguisher service knows that a flame has three significant components - heat, fuel, and oxygen. When heated beyond its ignition point, fuel starts to burn in the presence of oxygen, for those wondering why "oxygen" is because a fire cannot continue to burn without this chemical support of fire. 

The basic premise of a fire extinguishing system is relatively simple. It either cuts off the oxygen, covers the fuel, or lowers the temperature to kill the fire. The only issue with fires is that not every fire is the same and different types of fires require different types of fire extinguishers. This is why fire extinguisher classes exist. 

Before you put out a fire, you should know the suitable fire extinguishers to use. If you want complete guidance regarding the types of fires and fire extinguisher class, please do contact us - our experts will provide you with every information regarding fire, fire extinguishing and fire safety type services for the home. 

What is a Fire extinguisher Class?

Fire Extinguishers Nepal

As we mentioned, these devices are divided into different classes. These classes are based on the type of fire. You see, not every fire is the same, and if you use the wrong extinguisher, the flame may grow more prominent instead of dying. One of the most common examples of this is using water to kill the oil-based type fire. 

Water is one of the most common types of fire extinguishers. However, when it is used on oil fires, it instantly expands and increases the fire instead of putting it out. 

So what is the fire extinguisher class?

Class A

Under Class A, we cover fire extinguishers that are used in fires caused by traditional materials such as wood. Cloth, paper, and other general materials.The flames caused by or occurring on common material are also known as A-type Fire or Class A fire.

Class B

The fire extinguishers in this class are primarily used to put out fires caused by flammable liquids and gas.This includes everyday fuels such as petroleum, tar, oils, alcohol, kerosene, oil-based paints, greases, etc.

Like previous classes, flames caused by flammable liquid and gas are known as B type fire Class B flames, and the fire extinguisher used here is B type fire extinguishers. 

Class C

If you need to kill fires caused by or include electrical equipment, then a Fire extinguisher Class C is the one you need. 

Class D

Did you know that Metals catch fire as well? Metals such as Sodium, potassium, and Magnesium are prone to fire. If you encounter such fire, seek Class D of the extinguishers.

Class K

This one is meant for kitchen fires or, in general words, fires caused by and on vegetable oils and animal fats.

That said, there are variations even within the classes of fire extinguishers. This is all due to the materials used with these devices, as a single agent can be used to put out multiple types of flames. Under such circumstances, the classes of fire extinguishers are combined to form types such as AB fire extinguisher, BC type of fire extinguisher and ABC type fire extinguisher (ABC fire extinguishers)

Materials used in Fire extinguishers

Fire Extinguishers Nepal

Fire is started when combustible material is exposed to oxygen or any other oxygen-rich compound and reaches the flashpoint (the point of ignition). 

The only issue with this is that the flashpoint varies according to the materials. This leads to a strange situation where some flames are hotter than others and require various materials. Some fire extinguishing systems are great for one type of fire but hazardous for other classes. 

With all of this in mind, let's look at some common materials used in fire extinguisher services.


Water is the got to for Fire extinguishers and is among the most versatile to put out fires that are of low or average heat. It lowers the temperature and separates the fuel from the heat under normal circumstances when used. 

There are a few drawbacks of marine fire extinguishers (water fire extinguishers). One of the most prominent ones is that you cannot use this if the fire is extremely hot. This causes fire to evaporate before it reaches the fuel source. Since water is basically oxygen with hydrogen, evaporated water provides more oxygen that can help the fire. 

Water essentially acts as a fire blanket, preventing the fire from reaching the fuel source along with blanketing it from the heat. 

Carbon Dioxide Gas

While water cuts off the fuel from the heat, carbon dioxide works by cutting off oxygen from the fire. A fire cannot burn without Oxygen - that is a given fact. 

By replacing the oxygen with a heavier carbon dioxide gas, the fire loses its source to maintain the heat and then collapses. This is great for using as a Class B and Class C fire extinguisher.

There are a few drawbacks. The first one is that you cannot use this in an open and windy location since the wind can essentially disperse the gas. The second one is that Carbon Dioxide fire extinguishers have a relatively short range which can be impractical in many situations.

Dry Powder fire extinguisher

Being the third most common type of fire extinguisher, it is among the most versatile ones as well. The premise behind the Dry Powder Fire extinguishing system is simple - cut off the fuel from heat and oxygen.

Since these are essentially dry heat-resistant powders, you don't need a specific can to hold them. It can easily be compacted into fire explosion balls that explode and disperse the power when in contact with flames. These balls can be thrown from a safe distance, making them easier and safer. 

There are a few drawbacks. The first one is that without proper fire extinguisher training, you may find it hard to throw these small balls properly. Another one is that if it is used improperly, the powder can sometimes absorb the fuel and help the fire instead.

You can see Dry Powder type Fire Extinguishers being termed as Class D for the most part. However, they can be used in some specific metals as well, so they do have some form of versatility. Because of this, you can find some ABC type fire extinguisher (ABC fire extinguishers) as well. 

How to use a Fire Extinguisher?

Now that you know what a fire extinguisher is, its classes, and some common materials. It's time to know how to use one. If you have never used any form of fire extinguisher, then don't worry - it is extremely easy. 

All you need to do is follow the Pass guidance step. This essentially says:

  • P: Pull the pin on the extinguisher and break the seal
  • A: Aim low with nozzle and point it at the base of the fire
  • S: Squeeze the handle to release the agent
  • S: Sweep the nozzle from side to side while keeping it focused on the base of the fire.

If you have a fire explosion ball in your hand, then the step is even simpler. You need to step away from the fire and throw the ball. The paper covering will ignite and cause an explosion that releases the dry powder agent to kill the fire.

Fire Extinguisher Refilling in Nepal

Fire is both beautiful and scary. On the one hand, it helps us stay warm and cook food. At the same time, it is also responsible for any destruction. People still haven't forgotten the massive fire that blanketed the skies of Nepal just a few years ago.

Although it was a forest fire, who can say that the same thing cannot happen right in your home? In fact, with just a small miscalculation, your entire house could be engulfed in fire. This is the primary reason why many people are investing in fire safety equipment and measures and fire extinguishers In fact fire extinguisher is one of the simplest and most effective methods of fire safety. But what do you do once you use the fire extinguisher or the fire extinguisher expires?

You refill them! In fact, refilling a fire extinguisher is not an option but a necessity! That said, What are the methods of refilling fire extinguishers in Nepal?

Let's get to the bottom of this, starting with the why and when a fire needs to be refilled. Unless you know these answers, even if you know the methods of fire extinguisher refilling in Nepal, you will not increase your fire safety. 

Let's get started!

Why do fire extinguishers need to be refilled?

If you have a brand new fire extinguisher, it naturally doesn't need to be refilled. However, the older the fire extinguisher gets, the more it possesses risk.

For those unaware, a fire extinguisher is not just a can filled with clean agents to put out the fire, rather it is a complex little machine. The clean agents for fire extinguishers are put in a pressured or charged environment. The agents, especially if they are chemical ones, have their expiration date.

Here are a few scenarios why you need to have a refilled extinguisher:

Undercharged Extinguishers can harm you

If the fire extinguisher you have in hand is undercharged or overcharged, it will just be a cumbersome can in case of fire. In the worst-case scenario, it can affect the fire suppression when used, causing harm to the user and the property surrounding it. 

Depressurized extinguishers are useless

Similarly, when a depressurized fire extinguisher is used, it won't be usable. Although it won't explode, if you can't use a fire extinguisher during an emergency fire suppression, the results can easily be fatal.

Expired Extinguishers are as good as having none

As for the expiration of extinguishing agents, the result is simple- it will not be effective when used. Although fire extinguishers can technically last forever, their effectiveness does decrease. There will be a point where the effect of the said fire extinguisher is as good as none - and this is extremely dangerous during a crisis. 

During each one of these conditions, you must consider refilling the fire extinguisher in Nepal

Besides these, there is also an obvious situation why a fire extinguisher must be replaced; when the fire extinguishing agents inside are used up. 

The fire extinguishing agents can be:

The good news is that fire extinguishers can easily last a few years without any maintenance. If you are looking for a reliable fire extinguisher, please do let us know, or you can simply check our products!

When do Fire extinguishers need to be refilled?

The simplest answer to this is after you have used up all the fire extinguishing agents inside a fire extinguisher. 

The only catch is that you may not use all the agents inside a fire extinguisher. Even so, you must refill the fire extinguisher immediately after use. The only alternative option to this is to dispose of the extinguisher, which is simpler but not a recommended action. 

If you do not refill and recharge the fire extinguisher immediately after use, then the extinguisher will depressurize. We have already mentioned the risk of depressurized fire extinguishers. 

Besides this, a fire extinguisher should also be replaced and recharged every once in a while. This is to ensure that the quality of the agent inside the extinguisher has not degraded. Refilling of fire extinguisher will also ensure that the charge and pressure inside the canister will remain optimum for immediate action. 

Keeping this in mind, it is always a good idea to check your fire extinguisher every once in a while. If you see signs of any dents, corrosion, or nozzle damage, immediately take it to a servicing center to refill the agents inside and repair the damage or dispose of it. 

How to Check a Fire extinguisher Gauge?

The process of checking the fire extinguisher gauge is quite simple. Every fire extinguisher has a gauge with a red and green meter. If the pointer is in the green area of the pressure gauge, then you are affirmed that the extinguisher is properly pressurized. 

If the pointer is in the red area, then it is either under pressurized or over-pressurized. If the pressure gauge is in such a condition, immediately take the extinguisher to a refilling station. Then, you can re-pressurize the device and refill it if needed. 

If your fire extinguisher does not have a pressure gauge, you can press the pin. The pin should pop if the pressure is optimum. At the same time, if your fire extinguisher is a Carbon Dioxide type fire extinguisher, you can check the weight. If the weight is lesser or greater than the one mentioned, get it serviced immediately. 

How to refill a fire extinguisher?

Don't! Unless you are experienced with fire extinguishers by either being involved in the manufacturing process or refilling of fire extinguisher process, it is best to not tamper with the device. 

Although fire extinguishers are not toxic and are not hazardous for the most part, it is still heavy metal can filled with pressurized chemicals. You probably don't have the internal condition or have the devices required to refill the extinguisher. If you need refilling, please do let us know. We house professional fire safety experts and provide quality Fire Extinguishing Refilling Services for you. Do not put yourself or your property at risk.

Now that this is out of the way and you are qualified personnel and just need a quick review, the following are step-wises processes of fire extinguisher refilling in Nepal!

  • Step 1: Depressurize the extinguisher 

  • Step 2: Remove the agent from the canister

  • Step 3: Remove the Discharge valve from the cylinder

  • Step 4: Remove the siphon tube from the valve

  • Step 5: Detach the valve stem and spring

  • Step 6: Clean the valve and replace the neck-ring

  • Step 7: Inspect the internal extinguisher for the damage and install the new valve system.

  • Step 8: Refill the extinguishing agent in the appropriate portion

  • Step 9:Re-pressurize the appropriate pressurizing gas

  • Step 10: Test for leaks and reinstall the discharge nozzle/ hose

  • Step 11: Recheck for the weight and ensure that it is within the range set by the manufacturer

  • Step 12: Add a new tamper seal on the safety pin and recharge tag to the unit. 

Once you complete all of these steps, your fire extinguisher will be as good as new. Although these steps may seem simple, you must be intimately familiar with the internal workings of a fire extinguisher. If not, there will always be an extremely good chance to damage the extinguisher. Naturally, you will cause more harm than good if this ever happens. 

It should also be noted that different classes of fire extinguishers have different refilled extinguishers. While the one we mentioned is a general method, the specification of the valve, nozzle and gauge can differ from brand to brand. Along with this, although fire extinguishing agents are nontoxic, they are not exactly safe either. Should they be mishandled, they can pollute your environment. 

Fire Extinguisher That Doesn’t Need Refilling

The only exclusion to all of the processes that we have mentioned so far is the fireball fire extinguishers. These explosive balls of dry powder extinguishing agents are meant for one-time use and are thrown into the fire from a safe distance. Fire Balls are becoming quite popular tools during fire fighting in modern times since they are mostly ABC grade dry powder fire extinguishers that cover a large area and can be deployed from a distance; A very valuable asset during open area fire fighting. 

Despite not needing to be refilled, they can be unusable if they exceed their shelf life. 


Fire is both a boon and a curse to humans. While it does provide warmth and a cooking method to us, it can also easily cause us harm. A small mishap can easily ruin our lives. This is why fire safety equipment and measures are important.

A fire extinguisher is one of the most common and cheapest fire safety equipment and methods. That said, they can go bad as well, and if not replaced or refilled periodically, they will simply become an ornament or, worse, a fire hazard. 

A fire extinguisher that cannot be used during a crisis is not worse than the fire itself.

As a side note it should be helpful to remember that even though fire extinguishers are not the primary tools used by the firefighters during fire fighting, having a multi-purpose fire extinguisher like ABC dry powder fire extinguisher would help a lot.
