Carbon dioxide is the extinguishing agent in the fire extinguishers. The extinguishing agent has a very low temperature after leaving the pressure vessel - at the mouth of the nozzle about -30 ° C, it is therefore necessary to hold the nozzle by the handle only. Not suitable for extinguishing solids. For extinguishing it is possible to use not only snow, but also gas, which escapes from the nozzle after exhaustion of snow.
