5K fire extinguisher

Carbon Dioxide (CO2) fire extinguishers Can be identified by their black label and are for use on Class B fires, which are those that involve flammable liquids like paraffin, petrol or paint. They are also ideal for locations where there is a lot of electrical equipment, and therefore a risk of electrical fire, such as offices and as they are safe to use on electrical apparatus.CO2 fire extinguishers work by smothering the fire and reducing the oxygen level so there isn’t enough for the fire to feed on. CO2 is ice cold when it’s released from the fire extinguisher it also means the user must be extremely careful as it’s possible to get serious cold burns if skin comes into contact with the fire extinguisher horn. Although some CO2 extinguisher horns are frost-free, to be on the safe side never touch them when the extinguisher is in use.
