Portable CO2 fire extinguishers
Carbon Dioxide (CO2) Fire Extinguishers are distinguished by a black coloured band around the top of the cylinder. Carbon dioxide is a non-conductive and non-corrosive gas used to reduce the amount of oxygen available to the fire. Carbon dioxide is extracted from the atmosphere and stored at high pressure in the liquid state within a fire extinguisher.
Carbon Dioxide Fire Extinguishers are suitable for the following types of fires:
Class B – Flammable liquids
Class E – Electrically energised equipment
Portable foam fire extinguishers
Foam fire extinguishers are marked with a blue band. Foam fire extinguishers work by covering a burning flammable liquid with a blanket of foam, cutting off the fire’s air supply and preventing the release of flammable vapours.
Foam Fire Extinguishers are suitable for the following types of fires:
Class A – Paper, textiles, wood, most plastics & rubber
Class B – Flammable liquids
Portable Dry power fire extinguishers
Regular dry chemical fire extinguishers contain a siliconized sodium bicarbonate based dry chemical with free flowing and non-caking additives. Economical Class B & C protection with lower initial cost and recharging. This chemical smothers fires in flammable liquids & pressurized gases and is electrically nonconductive.Multipurpose dry chemical or ABC fire extinguishers contain a specially fluidized and siliconized mono ammonium phosphate chemical. It chemically insulates Class A fires by melting at approximately 350°F, coating the surface to which it is applied. It smothers & breaks the chain reaction of Class B fires and will not conduct electricity.
Wheeled fire extinguishers
Wheeled portable fire extinguishers can be easily operated by one person and are differentiated from "hand portable" types often simply on the basis of their capacity or total weight. Wheeled units are available in a variety of sizes and extinguishing agents with capacities that range from 30 to 350 pounds. Wheeled fire extinguishers are chosen for the higher capacity (volume), higher flow rates, extended fire fighting range and extended discharge time.
