What should a carbon dioxide fire extinguisher be used on?
Carbon Dioxide fire extinguishers extinguish fire by taking away the oxygen element of the fire triangle and also be removing the heat with a very cold discharge. Carbon dioxide can be used on Class B & C fires. They are usually ineffective on Class A fires.
a gas was produced or chemical reaction occurred. Possible answer: the baking soda and vinegar produced carbon dioxide that put out the fire. fire extinguisher is full of carbon dioxide. When you put the carbon dioxide on a fire, the fire can't get the oxygen it needs to burn, so it goes out.
- It's there because they put it there. Dissolved carbon dioxide is carbonic acid, which adds a pleasantly acidic flavor and an interesting mouth-feel. When it's not present, the drink tastes flat. When beverages get warm, the gas molecules have more energy and leave more quickly, and the soda gets flat faster.
- CO2s are designed for Class B and C (flammable liquid and electrical) fires only. Carbon Dioxide is a non-flammable gas that extinguishes fire by displacing oxygen, or taking away the oxygen element of the fire triangle.
- The primary chemical used to fight these fires is monoammonium phosphate, because of its ability to smother fires in these types of materials. Fire extinguishers with a Class B rating are effective against flammable liquid fires.
Human Wonder Research: Carbon Dioxide and Fire. Combustion (burning) is a chemical reaction in which a fuel reacts with an oxidant, usually oxygen, ordinarily producing both heat and light. In the absence of an oxidant, such as in pure carbon dioxide, combustion ceases.
- Carbon monoxide is produced by the incomplete combustion of carbon-containing fuels, such as gas (domestic or bottled), coal, oil, coke and wood. Gas stoves, fires, heating boilers, gas-powered water heaters, paraffin heaters, and solid fuel-powered water heaters are all potential sources of carbon monoxide.
- Sodium bicarbonate, also called sodium hydrogen carbonate, or bicarbonate of soda, NaHCO3, is a source of carbon dioxide and so is used as an ingredient in baking powders, in effervescent salts and beverages, and as the main constituent of dry-chemical fire extinguishers.
- When the liquid carbon dioxide inside the extinguisher expands into a gas, the carbon dioxide pushes out any oxygen surrounding the fire. Without oxygen available to fuel the chemical reaction, the fire goes out quickly. In addition to carbon dioxide extinguishers, fire extinguishers use other methods to put out fires.
