What is water CO2 fire extinguisher?
These extinguishers are use CO2 and water store with pressure released on the surface and is most effective in guarding electrical fire and provide safety against “A” class of the fire which involves material like wood, paper, cloth, plastics & fiber, rubber etc.
What is difference between water and carbon dioxide as a fire extinguisher?
The fire extinguishing process for water and carbon dioxide is as follows: Explanation: Water act as a barrier between the fuel and the oxygen present in the air this prevents the combustion effect whereas the carbon dioxide takes the place of oxygen so there will be no combustion of fuel.
What can a CO2 extinguisher be used on?
What is a carbon dioxide fire extinguisher used for? Carbon dioxide fire extinguishers are mainly used for two specific fire classes: Class B and electrical fires (Electrical risks). A Class B fire usually involves some sort of flammable liquid such as petrol or oil (not cooking oils or fats).
How do water fire extinguishers work?
Water and Water Additive Fire Extinguishers work by spraying a jet of water at the fire, which extinguishes the flames and the burning materials, preventing the fire re-igniting.
What is CO2 fire extinguisher used for?
CO2 fire extinguishers contain pure carbon dioxide which is a clean extinguishant, leaving no residue. Suitable for class B flammable liquid fires (petrol, oil, solvents), and recommended for use on live electrical equipment.
How does a CO2 fire extinguisher work?
How do CO2 Fire Extinguishers Work? The CO2 Extinguisher Cannisters contain carbon dioxide in liquid form, and when the extinguisher is let off the liquid is released into the air neutralising the oxygen that the fire is feeding on, disabling the fires ability to spread.
What is a water extinguisher used for?
Water extinguishers are used on solids such as wood, paper, fabrics and other A class fire risks. The water cools the fire and extinguishes it. It penetrates into burning fabrics and can extinguish pockets of fire even deep in the core of the fire.
Where are CO2 fire extinguishers used?
electrical fires
CO2 fire extinguishers are mainly aimed at electrical fires but are also suitable for Class B liquid fires and are used in different ways depending on the type of fire they are being used on. Do not use CO2 extinguishers in small rooms as CO2 gas is poisonous at only 4% concentration and can kill at just 8%.
What is the Colour of CO2 fire extinguisher?
black
CO2 fire extinguishers have a black label. They were originally designed for use on flammable liquid fires and therefore have a class B fire rating. They can be used on electrical fires, as CO2 is not a conductor and they do not leave behind any harmful residue.
What class is a CO2 fire extinguisher?
Class B Fires

How do CO2 extinguishers work?
CO2 extinguishers work by smothering the fire and cutting off the supply of air. Carbon Dioxide Extinguishers (CO2) have a black label. Wet chemical extinguishers are suitable for use on Class F fires involving cooking oils and fats, such as lard, olive oil, sunflower oil, maize oil and butter. They are extremely effective, when used correctly.
What type of fire extinguisher is used to fight Class A fires?
Water Based Fire Extinguishers Water extinguishers are one of the most cost-effective ways to fight Class A fires, those fuelled by solid materials such as paper, wood and textiles. There are four different types of water extinguishers: water jet, water spray, water with additives and water mist or fog. All water extinguishers have a red label.
What is the difference between carbon dioxide and foam fire extinguishers?
Carbon dioxide extinguishers do not leave any residue, unlike a foam extinguisher. They can also be used on Class B fires, those involving flammable liquids such paraffin or petrol. CO2 extinguishers work by smothering the fire and cutting off the supply of air. Carbon Dioxide Extinguishers (CO2) have a black label.
What is a powder extinguisher used for?
Powder extinguishers are a good multi-purpose fire extinguisher because they can be used on Class A, B and C fires. They can also be used on fires involving electrical equipment however, they do not cool the fire so it can re-ignite. Powder extinguishers can also create a loss of visibility and may create breathing problems.
