Fire Extinguisher Refilling: Nepal Best Service Station

Fire Safety: Extinguisher Maintenance and When to Refill Your Cylinder in Nepal as per International Practice and Expiry Dates.

Regular inspections and upkeep are essential for your fire extinguisher to guarantee optimal performance. This article will explain the operation of your fire extinguisher, the proper maintenance of the cylinder, and when it should be refilled. Knowing this is crucial for effectively managing and putting out fires in your home or property.

​What is the mechanism behind the functioning of extinguishers?
A fire extinguisher typically contains two substances in a large aerosol can: a solid, gas, or liquid substance, and a propellant. Propellants are chemicals under pressure that expel fire-extinguishing agents from their containers when the trigger is activated.

Knowing when to use each of the four main types of fire extinguishers is just as important as understanding their functionality. Using the incorrect fire extinguisher to combat a fire can potentially worsen the situation instead of improving it.

1. Water Extinguishers: Tanks filled with water utilize carbon dioxide or nitrogen as propellants. Water-based fire extinguishers are the most commonly utilized type, working by removing heat and depriving the fire of oxygen.

2. Foam fire extinguishers are equipped with tanks filled with foam and nitrogen as their propellants. Foam extinguishers put out fires by suffocating them and soaking up their heat. When activated, the foam expands thinly across the fire, reducing oxygen supply and trapping the heat. The water in the foam helps enhance its ability to absorb heat.

3. Dry Powder Extinguishers : Dry powder is the main component in these extinguishers, which use nitrogen to propel it. Dry powders in this scenario are utilized to soak up heat, then liquefy and cover the fuel, ultimately hindering oxygen access and controlling the fire. Dry powder usually consists of a combination of substances such as mono-ammonium phosphate, potassium bicarbonate, sodium bicarbonate, and others.

4. CO2 Fire Suppressors: CO2 fire suppressors contain both gaseous and liquid carbon dioxide in tanks, compressed at high pressure to further liquefy it. Upon release, the gas expands, suffocating oxygen and soaking up nearby heat as it transitions from a liquid to a gas (known as the latent heat of vaporization).

Tips for Fire Extinguisher Maintenance
A faulty fire extinguisher can result in catastrophic outcomes. Hence, it is necessary to regularly check and upkeep the cylinder to ensure it remains in optimal condition. Here are some guidelines to adhere to for effectively caring for your cylinder:
1. Perform regular visual checks on your fire extinguishers every month.
2. Regularly visually checking your fire extinguishers each month provides benefits such as:
3. Make sure the fire extinguishers are easily reachable.
4. Verify if there are any damages, such as cracks, rust, or dents, on the cylinder.
5. Make sure the pin and tamper seal are correctly positioned.
6. Verify if there are any damages or signs of wear on the hose and nozzles (if they are present).
7. Verify that the needle on the gauge is indicating the green section on the dial, etc.
If any of these are not functioning properly, reach out to a licensed and professional fire extinguisher maintenance company for potential solutions.

B. Inspect all fire extinguishers once a year.
In addition to the regular monthly inspections, make sure to have your fire extinguishers serviced annually - let our professionals at Control Fire Systems take care of this task for you. Following maintenance, make sure each fire extinguisher is equipped with a label displaying the most recent inspection and maintenance date for easy reference.

• You might have to repair or replace any fire extinguisher as advised by the maintenance company you hire.
• When it is time to recharge your fire extinguisher tank.
• Filling up your cylinder is a crucial part of maintaining a fire extinguisher, making sure that the device is ready for use when necessary. Yet, recognizing the significance of replenishing is distinct from being aware of when a refill is necessary. Below are a variety of explanations for why you should recharge your fire extinguishers.
• Fire extinguishers must be refilled promptly after being used.
• You should plan regular refills for fire extinguishers during their entire life span, regardless of whether they have been utilized or not. Refilling is usually done every six to twelve years from the date of manufacture.
• Harm, dings, and various environmental elements could cause depressurizations. Therefore, it is important to inspect and top up your extinguishers whenever any of these signs are noted.
