Replacement for bicarbonate soda

For the candle extinguisher, see candle snuffer. A fire extinguisher is a handheld active fire protection device usually filled with a dry or wet chemical used to extinguish or control small fires, often in emergencies. There are two main types of fire extinguishers: stored-pressure and cartridge-operated. In stored pressure units, the expellant is stored in the same replacement for bicarbonate soda as the firefighting agent itself.

Depending on the agent used, different propellants are used. The first fire extinguisher of which there is any record was patented in England in 1723 by Ambrose Godfrey, a celebrated chemist at that time. It consisted of a cask of fire-extinguishing liquid containing a pewter chamber of gunpowder. This was connected with a system of fuses which were ignited, exploding the gunpowder and scattering the solution. Thomas J Martin, an American inventor, was awarded a patent for an improvement in the Fire Extinguishers on March 26, 1872. His invention is listed in the U. Patent Office in Washington, DC under patent number 125,603.

The soda-acid extinguisher was first patented in 1866 by Francois Carlier of France, which mixed a solution of water and sodium bicarbonate with tartaric acid, producing the propellant CO2 gas. A soda-acid extinguisher was patented in the U. Campbell of England in 1881, which used water or water-based solutions. They later invented a carbon tetrachloride model called the “Petrolex” which was marketed toward automotive use. The chemical foam extinguisher was invented in 1904 by Aleksandr Loran in Russia, based on his previous invention of fire fighting foam. Loran first used it to extinguish a pan of burning naphtha.

Another type of carbon tetrachloride extinguisher was the fire grenade. Carbon tetrachloride was suitable for liquid and electrical fires and the extinguishers were fitted to motor vehicles. Walter Kidde Company in 1924 in response to Bell Telephone’s request for an electrically non-conductive chemical for extinguishing the previously difficult-to-extinguish fires in telephone switchboards. It consisted of a tall metal cylinder containing 7. It consisted of a copper cylinder with an internal CO2cartridge.
