Using Gas in Fire Extibusihers is common. But, Not all fire extinguishers use gas to extinguish the fire, but most of them do. Gas in Fire extinguishers is not harmful as using Foam and water.
In the Market, There are different types of Gases Fire extinguishers that are used to extinguish Fire.
These are the 4 Most common used Gases in Fire Extinguisher systems are;
- Carbon dioxide (CO2)
- Inert gas with inergen
- Clean agents (HFC-227ea and FK-5-1-12 )
Above all, In this article, I am gonna show you the complete information on the Type, features, Pros, and Cons of each type of Gas Fire Extinguishing System.
1. Carbon dioxide (CO2)
Carbon dioxide (Co2) is the most common Gas that most Fire extinguishers use. There is no need to clean carbon dioxide after discharge, like Cleaning Agent. Unlike cleaning agents, carbon dioxide extinguishes fire by removing oxygen, not heat.
This would be critical use that You can not use a carbon dioxide Fire system in the occupied spaces. As Because Co2 removed Oxygen, and if the oxygen level is down, it is a very bad condition for humans. If you use a carbon dioxide system to extinguish a fire, be sure to ventilate the area completely when the system shuts down.
It is highly recommended to not use CO2 gas in the electric equipment to prevent thermal shock. Thermal shock occurs because carbon dioxide can be stored at extremely cold temperatures.
Though, there are some limitations to using this gas, but, on the other hand, it has several Key Advantages. it is readily available and affordable. It is very easy to refill after the extinguisher is discharged and the price is very minimal. That’s why CO2 Fire Extinguisher is one of the good choices. By the way, if you want to refill your extinguisher you can also contact Arnavindia, The Best Fire suppression system supply online in Delhi.
2. Inert gas with inergen
Inert gases enough to remove Oxygen to prevent from Fir which acts like similarly. Instead of using Carbon Dioxide in the Close Locked Area, Using inert gases is safe. Its Does not deplete enough O2 which interferes with the Human’s Breath.
Some of the examples of Inert gas are;
It does not fully decrease the level of O2, So, it is safe for people.
It is safe for equipment.
Inert Gas does not contribute to global warming.
Typically, Inert gases are stored as gases whereas chemical cleaning agents are stored as liquids, and then it is compressed into gases. That’s why Chemical Agent is stored in a smaller container. However, inert gases flow better through piping, which means they can be stored farther away from potential fire sources.
3. Chemical Clean agents (HFC-227ea and FK-5-1-12 )
There are two types of Chemical Clean Agent, one is HFC-227ea and another is FK-5-1-12, that is used in the Clean Agent Fire Suppression sure. The Most commonly used Clean Agents are in Electrical Equipment and Machinery. Chemical Clean Agent does not damage any components of any part of Electrical Equipment. Clean agents can be used to protect occupied spaces such as electrical rooms, as they are safe for humans. The gas of it does not affect the Ozone Level.
The Manufacture of HFC-227ea type clean agent is ChemoursTM which sells with the Brand Name FM-200TM. To Entinguhs the Fire, block free radicals, which can help extinguish fires by interfering with key chemical reactions.
HFC-227ea is one type of heptafluropropane. Although there are some environmental concerns with HFCs, firefighting systems are largely exempt from laws that prohibit the use of HFCs.
FK-5-1-12 is another type of clean agent. 3MTM sells this chemical type under the Brand Name of NovektM1230. FK-5-1-12 suppresses fire by removing heat like the HFC-227ea foam agent.
Since FK-5-1-12 is not an HFC, it is generally considered to be more environmentally friendly. In terms of environmental effects, The NovecTM 1230 has less global warming than the FM200.
Halon is a gas that has the same advantages as Inert Gases Fire Extinguhser and Agent Fire Extinguisher have agents and inert gases. Probably, Halow had the fire extinguishing systems before using the Inert Gash and Cleaning Agenstsin the Fire Extinguisher
It is inert, safe for equipment, and effective in class A, B, and C fire suppression.
Basically, Halon Gas is Dangerous forEnvisonemenr, It has been shown to deplete the Earth’s ozone layer. Montreal Protocol ban Halon Gas in 1989. However, some older firefighting systems that are still in service may have Halon. But, Now, There is very minimal chance of using Halon Gas in Fire Extinguhser.
To sum up, these are the 4 types of Gases Used in Fire Suppression systems, such are Carbon dioxide (CO2), Inert gas with inergen, Clean agent (HFC-227ea and FK-5-1-12 ), and Halon. Which, the most common are Clean Agent Fire Extinguisher and CO2 Fire Extinguisher. So, I hope, you have got the complete details about Gases are used in Fire Extinguhser from this article.
Now, I’d like to know from you:
Which type of Gases Fire Extinguisher you will prefer?
