What class fire extinguisher should be used on electrical fires such as desktop pcs?
Carbon Dioxide(CO2) or Dry Powder.
What are the advantages and disadvantages of co2 fire extinguisher?
It can be safely used on electrical fires, it will extinguish burning liquids, and it leaves no residue behind.
Why is carbon dioxide in fire extinguisher?
Fires need oxygen, and the CO2 (carbon dioxide) smothers the fire by keeping oxygen away. CO2 is only used for certain types of fire, mostly wood, paper, cloth, and electrical fires. The CO2 displaces the oxygen. You spray a fire at its base with an extinguisher. Fires draw oxygen from its base by way of draft. The CO2 from the extinguisher is picked up by the fire and does not support combustion. For very large fires, CO2 is not as effective because of the rapid flow of air into the fire, which is caused by higher temperatures. Water or foam is better at cooling the fire and making the flammable materials harder to burn.
What will happen if you remove syphon tube from the CO2 fire extinguisher?
If you remove the siphon tube from a CO2 fire extinguisher, the extinguisher will not work properly. The siphon tube is responsible for drawing and releasing the CO2 gas from the extinguisher. Without it, the CO2 gas will not be able to flow out effectively, rendering the extinguisher ineffective in suppressing fires.
What fire do use a carbon dioxide fire extinguisher on?
A CO2 fire extinguisher will work on flammable liquid and electrical fires only. If used on any other type of fire they will just give it more oxygen and it will spread.
Which type of fire extinguisher should be used on an oil fire?
A Class A, B, C, or ABC fire extinguisher works wonders on several different types of fires. A is good for wood, paper, etc. B is good for liquids. C is good for electrical fires. Do not use a Class D, for these are best on metals (such as magnesium).
How does a carbon dioxide extinguisher put out an electric fire?
Yes, carbon dioxide (CO2) can be used by a firefighter (or a trained individual on scene) to extinguish an electrical fire. The carbon dioxide fire extinguisher is a specific type of fire extinguisher, and is in fairly common use. Compressed CO2 is pumped into the cylinder, and held in there behind a hand-operated valve. Pull he pin, grab the handle with one hand and the handle of the nozzle with the other, and get busy. Use the PASS system: pull the pin, aim the nozzle at the base of the flames, squeeze the handle, sweep the nozzle from side to side. The CO2 extinguisher can be distinguished by the large "cone" of its nozzle. Be sure to grab the nozzle by the handle as it is insulated. The CO2 exits the bottle and is really cold when it does. It will freeze your hand if you grab the nozzle or the hose instead of the handle. The extinguisher will make a fairly loud noise when you discharge it, but expect that and then ignore it. You're the first responder, and you can effectively use this device, just like a firefighter would.
What fire extinguisher do you use for a car fire?
A car extinguisher may be necessary for putting out several different types of fires, so it should be a Class A:B:C extinguisher, normally dry powder. For an irreplaceable classic, one might consider a CO2 or a "clean agent" extinguisher, to avoid the damage potential of dry powder chemical extinguishers.
What is the proper use for a carbon dioxide fire extinguisher?
If the question you're trying to ask is "Why can someone use carbon dioxide as a fire extinguisher?" The answer is that all combustion reactions (burning) require oxygen. Overwhelming the environment surrounding the fire with CO2 limits the amount of oxygen available to the reaction, stopping the fire.
What Safety measures are taken to extinguish different types of fires?
For a grease fire, use a fire extinguisher specifically labeled for grease fires or smother the fire by placing a metal lid over the pan. For an electrical fire, turn off the power source if safe to do so and use a Class C fire extinguisher. For a wood or paper fire, use a Class A fire extinguisher or water to extinguish the flames.
What type of fire extinguisher should you use for an electrical fire?
It is the Class C fires that invlove electrically energized equipments, and they are suppressed using CO2 extinguishers or dry chemical extinguishers. Certainly the use of water or water-based extinguishers or other water-based suppression equipment is not to be considered.
When would you use a CO2 extinguisher?
Carbon Dioxide extinguishers are used for plenty types of fire. It's most effective against fires corresponding to flammable liquids, electrical equipment, cooking oils & fats. Do NOT use a Carbon Dioxide extinguisher for solids (wood, paper, cloth, etc) and flammable gases.
