Co2 fire extinguisher is used to extinguish fire

The CO2 gas is heavier than the oxygen in the air so it effectively pushes it out, displacing it from around the fuel which is burning to cause the fire. The fire is extinguished because the oxygen it needs to feed the flames has been replaced by the carbon dioxide gas. CO2 fire extinguishers are created by storing a mixture of liquid and carbon dioxide under pressure. When stored like this, the mixture remains a liquid form. When discharged, the mixture expands rapidly. It is propelled at high speed as a cold white jet onto the flame. The CO2 works to smother the fire, greatly reducing the oxygen from the source.

March 26, 2022 Choosing fire extinguisher types for the relevant class of fire could literally be the difference between life and death. So here’s a useful guide on how to choose the right type and class of fire extinguisher for the appropriate scenario, including colour codes, fire classes and uses. No single extinguisher can be used to tackle every fire, and because each type of fire extinguisher has different categories of fire on which it is effective, selection can be a minefield. The good news is that portable fire extinguishers are effective and are saving lives. According to a survey from companies in the four main trade associations in the UK fire sector, the number of fires being successfully The first step is to look at what materials are present in the area to be protected from fire. These can be divided into six fire classes involving different substances: • Class A fire caused by combustible carbon-based solids such as paper, wood or textiles • Class B fire caused by flammable liquids eg paraffin, petrol, diesel or oil (but not cooking oil) • Class C fire caused by flammable gases, eg butane, propane or methane • Cla...

When Would It Be Dangerous to Use a Carbon Dioxide Fire Extinguisher? Carbon dioxide fire extinguishers, when used in the right circumstances can save lives. However, it would be dangerous to use a carbon dioxide fire extinguisher when dealing with flammable gases, cooking oils and fats, or in a confined space. In this article, we’ll detail the situations where a carbon dioxide extinguisher could be dangerous to use, as well as how they work and when and where you ought to be using them to tackle a fire. What are the risks with a carbon dioxide fire extinguisher? Asphyxiation – If a carbon dioxide extinguisher is used in an enclosed or poorly ventilated area, there is a serious risk of asphyxiation. Higher pressure – When discharged, the carbon dioxide in the extinguisher turns from liquid into gas. The working pressure is roughly 55 BAR (compared to 12 BAR in a water-based unit), this means that if someone were to attempt to use the extinguisher without the proper hose and horn fitted, there is a good chance the kick from the unit could cause injuries. This includes wrist strains, or at worst, a broken wrist. Quicker discharge – Due to the higher pressure, there is a quicker discharge on a CO₂ unit. This means that anyone using this extinguisher type should be certain they can put out the fire fully before trying to tackle it as it will quickly spend the contents once started. Frost burn – When the CO₂ turns from a liquid into a gas during discharge, the temperature is ex...

Carbon dioxide is a colourless, odourless, and non-toxic gas that has non-flammable properties. CO2 extinguishers are an important part of Purpose of the CO2 fire extinguisher: Carbon dioxide extinguishers are aimed at preventing the combustion of flammable liquids and electric fires, however, they are not suitable for use on flammable solids, flammable gases, or cooking fat fires. Carbon dioxide extinguishers are used in a variety of settings, including kitchens, restaurants, and public and private buildings, to extinguish fires. Carbon dioxide, on its own, will not put out a fire. The action is to absorb oxygen in the air, which can provide enough oxygen to burn fuel in a fire. The fire, in turn, needs oxygen to burn. This will slow the rate of the fire’s burning, and limit it. The advantage of carbon dioxide extinguishers is that they are safe for use in kitchens, restaurants, and pubs. They can be used when working with flammable substances such as cleaning products, paint, oil, gas, and petrol. CO2 fire extinguisher Types of CO2 fire extinguishers: There are many different types of CO2 extinguishers available. They are all rated according to how much they put off a fire. The extinguishers come in different sizes and different shapes. Large capacity: These are usually large-sized extinguishers and are generally used in restaurants. Medium capacity: These are used in other areas such as warehouses, factories, shops, and offices. Miniature extinguishers: These are also u...

In the hands of a trained person, portable fire extinguishers are great tools to protect people and property from fire during early stages. When using an extinguisher or selecting an extinguisher to install, it’s important to know the characteristics of different fire extinguishers. This blog will address the different types of fire extinguishers by breaking them down by their extinguishing agent, which is the material inside the extinguisher that gets applied to the fire. Class of Fire Description Class A Fires Fires in ordinary combustible materials, such as wood, cloth, paper, rubber, and many plastics. Class B Fires Fires in flammable liquids, combustible liquids, petroleum greases, tars, oils, oil-based paints, solvents, lacquers, alcohols, and flammable gases. Class C Fires Fires that involve energized electrical equipment. Class D Fires Fires in combustible metals, such as magnesium, titanium, zirconium, sodium, lithium, and potassium. Class K Fires Fires in cooking appliances that involve combustible cooking media (vegetable or animal oils and fats). Water Water is the primary liquid used in these extinguishers, although sometimes other additives are also included. A drawback for pure water fire extinguishers is that it is not suitable for use in freezing conditions since the water inside will freeze and render the extinguisher unusable. Certain types of water fire extinguishers contain antifreeze which will allow the extinguisher to be used in freezing conditions....

CO2 is a clean, safe, non-conductive, and naturally-occurring environment-friendly gas that won’t damage delicate electronic equipment. CO2 fire extinguishers are very effective in putting out fires caused by flammable liquids and electrical equipment. However, they can’t extinguish class A fires, have cold discharge that may cause injury or frostbite, cause limited visibility with a dense fog, and are not ideal for large or persistent fires. Let’s get to know more the advantages and disadvantages of CO2 fire extinguishers. Different Types of Fire Classes and Fire Extinguishers Here’s a quick overview of the different classes of fire and different types of fire extinguishers to give you a clear idea. There are mainly five types of fire extinguishers: • Water extinguisher (for Class A fires) • Foam extinguisher (for Class A and B fires) • Dry chemical extinguisher (for Class B and C fires) • CO2 extinguisher (for Class B and C fires) • Wet chemical extinguisher (for Class F fires) Fire classes are categorized based on the kind of fuel burning and causing the fire. The most common fire classes are: Class A – ordinary combustibles e.g. cloth, paper, wood, rubber, and plastics. Class B – flammable liquids e.g. gasoline, oil, and grease. Class C – fires associated with electrical equipment, such as appliances, wiring, and machinery. Class D – fires where flammable metals e.g. magnesium, titanium, and potassium are involved. Class F – fires associated with cooking oils and fats,...

Halotron and 2 extinguishers each have their advantages. Carbon dioxide is a trusted non-conductive clean agent and is most effective when used in electronic equipment fires. Halotron is a clean, non-conductive gaseous agent that is an excellent replacement for Halon 1211 extinguishers because it has a lower environmental impact and leaves no residue. Halotron interrupts the chemical chain reaction and cools the fuel to extinguish the fire. Carbon dioxide displaces oxygen and cools the fuel to extinguish the fire. Both Halotron and CO 2 are rated for Class B and The discharge range varies based on the size of the extinguisher. As you can see below, Halotron is capable of extinguishing a fire at a further distance than a CO 2 fire extinguisher. While the 2 fire extinguishers, the extended range and the more concentrated agent of Halotron make up for this slight disadvantage. CO 2 Time (in seconds) Range Halotron Time (in seconds) Range 10 lb 11 3-8 ft 5 lb 9 9-15 ft 15 lb 14.5 3-8 ft 11 lb 9 9-15 ft 20 lb 19.2 3-8 ft 15.5 lb 14 12-18 ft Hydrotest Frequency Service Intervals Every type of fire extinguisher needs to be serviced following any use. All portable fire extinguishers are required to have annual maintenance performed on them. In addition to this annual maintenance, Halotron units are required to have an internal examination every six years. Additional Advantages of Halotron Halotron extinguishers have a few additional advantages when compared to a CO 2 extinguisher....
