The foam was a combination of the products of the chemical reactions: sodium and aluminium salt-gels inflated by the carbon dioxide.

Some public and government buildings are often required, by local legal codes, to provide an identification sign for each extinguisher on the site.[43]. The intended purposes of Dry and Wet chemical extinguishing systems are to quickly extinguish fires and prevent fires from re-igniting. The information within our resources pages is copyrighted to SAFE I.S. Under NFPA 10 all commercial vehicles must carry at least one fire extinguisher, with size/UL rating depending on type of vehicle and cargo (i.e., fuel tankers usually must have a 20 lb (9.1 kg), while most others can carry a 5 lb (2.3 kg)). Fire Extinguisher Online's high quality and easy to use range of Wet Chemical Fire Extinguishers are designed to extinguish Class E (cooking oils or fats) plus small Class A fires. Na-X cartridge-operated sodium carbonate fire extinguisher for sodium fires using non-corrosive agent. Modern Pyromet made by Chubb Fire is a graphite formulation. His invention is listed in the U. S. Patent Office in Washington, DC under patent number 115,603. Fire department types were often private label versions of major brands, sold by apparatus manufacturers to match their vehicles. The number preceding the B indicates the size of fire in square feet that an ordinary user should be able to extinguish. Such signs are independent of an external power supply, and so offer a low-cost, reliable means of indicating the position of emergency equipment in dark or smoky conditions. Examples include the Fire Blockade and FireAde brands of suppressant. To the difference of gaseous suppressants, which emit only gas, and dry chemical extinguishers, which release powder-like particles of a large size (25–150 µm) condensed aerosols are defined by the National Fire Protection Association as releasing finely divided solid particles (generally <10 µm), usually in addition to gas.[37]. Fire extinguishers in a museum storeroom, cut to display their inner workings. This 2 litre wet chemical extinguisher is ideal for small kitchens, being able to tackle those fires fuelled by waste paper baskets and burning cooking oil. They are referred to as clean agents because they do not leave any residue after discharge, which is ideal for protecting sensitive electronics, aircraft, armored vehicles and archival storage, museums, and valuable documents. Specifications for fire extinguishers are set out in the standard AS/NZS 1841, the most recent version being released in 2007. Potassium salts are sprayed out as a fine mist (gently, so as not to spread the burning oil or fat), and these react to create a soapy film on the surface of the substance on fire. Halon was completely banned in Europe and Australia except for critical users like law enforcement and aviation, resulting in stockpiles either being destroyed via high heat incineration or being sent to the United States for reuse. Both 1211 and 1301 work by inhibiting the chain reaction of the fire, and in the case of Halon 1211, cooling class A fuels as well. Similar signs are available for other fire equipment (including fire blankets and fire hose reels/racks), and for other emergency equipment (such as first aid kits). According to NFPA, the system must provide record keeping in the form of an electronic event log at the control panel. Such signs may be manufactured from a variety of materials, commonly self-adhesive vinyl, rigid PVC, and aluminum. A reflective material will only return ambient light for as long as the light source is supplied, rather than storing energy and releasing it over a period of time. Potassium aerosol particle-generator, contains a form of solid potassium salts and other chemicals referred to as aerosol-forming compounds (AFC). In Australia, yellow (Halon) fire extinguishers are illegal to own or use on a fire, unless an essential use exemption has been granted, this is due to the ozone-depleting nature of halon.[15].
