Most dry chemical fire extinguishers are pressurized to around 150 psi but some rely on a CO2 cartridge to pressurize the fire suppressant inside. Without CO2, the suppressant wouldn't come out.
Some fire extinguishers are filled with high pressure CO2 and the CO2, by itself, serves as the fire suppressant. CO2, as it expands, absorbs considerable heat. The gas is also heavier than air and will not support combustion so it displaces the oxygen that the fire needs to burn.
CO2 is not very effective against burning solids because the heat can cause the solids to re-kindle. Blowing a CO2 extinguisher into a trash can full of burning paper can cause the still-burning paper to become scattered and spread the fire. Since CO2 displaces oxygen, using it in an unventilated space can also suffocate people.
Bear in mind that the horn of the CO2 fire extinguisher becomes very cold and can cause moisture to condense. If you are fighting an electrical fire, that moisture can conduct electricity and possibly electrocute you.
Yes, a carbon-dioxide type of fire extinguisher contains ONLY carbon dioxide. Other extinguishers might use compressed nitrogen or other inert gases as propellants, as well as compressed carbon dioxide.
because fire needs oxygen to burn ,if you use carbon dioxide on the fire,then it will not be able to burn due to the lack of oxygen.Thus the fire will go out.
Because Co2 is the thing that puts out fires in fire extinguishers.
The contents of some fire extinguishers are indeed a gass (Carbon Dioxide)
I shouldn't think that it can be used in that way. Indeed the foam used in some fire extinguishers is made up of lots of bubbles of carbon dioxide.
Yes, carbon dioxide is found in some types of fire extinguishers. In others, nitrogen gas or compressed air is used. Some expensive types contain other pressurized gases such as Halotron or similar "clean agents" that leave no residue.
it is a non-flammable gas that is effective at starving a fire of oxygen. Like other fire extinguishers (foam and water) it is only recommended for fighting certain types of fire. more infromation and recommendations on their use should be available through the fire department.
Carbon Dioxide is used in extinguishers meant for use on electrical fires.
Some fire extinguishers use dry chemicals and some use a foam to extinguish flames. Some fire extinguishers actually still use water, but they're only for use on smaller fires. Others use a dry chemical, mostly sodium bicarbonate, or Carbon Dioxide.
No, helium is not used in fire extinguishers. We find carbon dioxide (CO2) in some extinguishers, but not helium.
It's actually the other way round. Carbon dioxide is used in some fire extinguishers to put fires out. It prevents oxygen from reaching the fire and the fire cannot continue to burn.
Carbon dioxide is used to carbonate beverages, and makes breads and cakes rise. Some fire extinguishers blanket the fire with heavy carbon dioxide to prevent the lighter oxygen from getting to the fuel. It is also used in supercritical fluid extraction to decaffeinate coffee.
Depends on what type it is and whether it is fixed or portable. There are many different kinds of fire extinguishers, some pressurized by air, nitrogen, carbon dioxide, among other things.Read more: What_is_the_chemical_reaction_in_fire_extinguishers
carbon dioxide is significantly denser than air and tends to settle on the ground displacing oxygen and putting out the fire. Nitrogen makes up 78% of the atmosphere so 100% nitrogen isn't very different in density than air.
