The carbon dioxide stored inside the extinguisher is kept at ice-cold temperature. The cold helps to lower down the heat of the fire, consequently killing it. However, when the extremely cold carbon dioxide comes in contact with the bare skin, it can cause severe frostbite.
CO2 gas is held in the fire extinguisher under pressure, normally around 55 bars at room temperature. By comparison, pressure cookers operate at 1 bar of pressure, modern car tyres are usually inflated to a maximum of 2.5 …
What is a CO2 extinguisher discharge temperature? – Answers
What is a CO2 extinguisher discharge temperature? CO2 is delivered at the horn output at approximately -130 degrees F.
Using the extinguisher: • Aim the horn at the base of the fire and move the jet of CO2 backwards and forwards. • Electrical fires: Switch off the electrical item if it is safe to do so. • Liquid fires: Take care not to splash the burning liquid onto …

What is the pressure of CO2 in a fire extinguisher?
CO2 gas is held in the fire extinguisher under pressure, normally around 55 bars at room temperature. By comparison, pressure cookers operate at 1 bar of pressure, modern car tyres are usually inflated to a maximum of 2.5 bars, whilst airliner tyres are inflated at up to 14 bars. At…
What happens to CO2 when it is discharged from a CO2 extinguisher?
A more complex physical reaction happens as the CO2 is discharged: the sudden drop in pressure as the liquified CO2 expands results in a rapid drop in temperature, producing pellets of dry ice (solid carbon dioxide). The cloud you see when a CO2 extinguisher is activated is mostly water vapor condensed from the atmosphere by the cold gas.

We are use the co2 as fire extinguisher What type of fire extinguisher should be used on computer equipment? CO2 extinguisher Which chemical is used in Co2 fire extinguisher? CO2- carbon dioxide What type of fire extinguisher can be used in electrical fire? A dry powder extinguisher, a CO2 extinguisher or a halon gas system.
How does a carbon monoxide fire extinguisher work?
When the valve is opened, the highly compressed carbon monoxide, normally held in a semi-liquid state under pressure in the fire extinguisher body, is rapidly released. As the gas changes into a gaseous state, it freezes moisture present in the air, forming a white cloud of gas and frozen water…
