House fire fighting technique
View Patent ↗This patent is about fighting house/apartment/condo/building fires by using dry ice and/or carbon dioxide gas. By the time people call the authorities, the fire has grown so big that it is difficult to control or to extinguish by ordinary fire fighting techniques. Traditional house fire fighting is to spray water into the house so that the flames would disappear and stop burning. This patent involves two methods: 1) throwing, spraying or spreading powder or flakes or pellets of dry ice on or near the fire or around the fire so that the carbon dioxide sublimating from it diffuses and expands to get to the fire or to fill up the house or around the house so that oxygen cannot get into the fire to continue burning; 2) spraying carbon dioxide gas into the house, apartment or building to bring down the oxygen level to stop the fire.
1 . A method of extinguishing a fire comprising steps of:
carrying, by a fire fighter on a back of the fire fighter, one cylinder only of carbon dioxide gas and a plastic pipe, the plastic pipe including a first end orifice and a second end orifice only, the first end orifice of the plastic pipe being communicatively connected to the one cylinder;
spraying, via the second end orifice only of the plastic pipe, by the fire fighter without using drones, carbon dioxide gas only from the one cylinder into, on or around a burning building, house or apartment to reduce a ratio of oxygen available in air that is feeding the fire to below fifteen percent to extinguish the fire, wherein carbon dioxide gas remaining after the fire is extinguished flows to lower levels of the building, house or apartment; and
blowing the remaining carbon dioxide gas out of the lower levels so people can breathe in the lower levels.
2 . The method according to claim 1 , wherein the plastic pipe is configured to be supported by a rigid pole or an extendable pipe.
3 . A method of extinguishing building fires comprising steps of:
carrying, by a fire truck, one cylinder of carbon dioxide gas;
delivering, by the fire truck, the one cylinder of carbon dioxide gas to a site of a building fire;
communicatively connecting a first end orifice of a plastic pipe to the one cylinder of carbon dioxide gas, the plastic pipe including the first end orifice and a second end orifice only;
spraying, via the second end orifice only of the plastic pipe without using drones, carbon dioxide gas only from the one cylinder of carbon dioxide gas on the building fire, wherein the carbon dioxide gas is sucked into the building fire to reduce a ratio of oxygen available in air that is feeding the fire to below fifteen percent to extinguish the building fire, and carbon dioxide gas remaining after the fire is extinguished flows to lower levels of a building in which the fire was extinguished; and blowing the remaining carbon dioxide gas out of the lower levels so people can breathe in the lower levels.
4 . The method according to claim 3 , further comprising aiming the second orifice end of the plastic pipe at openings in the building to spray the carbon dioxide gas into the building, wherein the carbon dioxide gas expands and reduces an amount of oxygen causing the building fire to be extinguished.
5 . A method of extinguishing a fire comprising steps of:
carrying, by a fire fighter on a back of the fire fighter, one cylinder only of carbon dioxide gas and a plastic pipe, the plastic pipe including a first end orifice and a second end orifice only, the first end orifice of the plastic pipe being communicatively connected to the one cylinder;
reducing a ratio of oxygen available in air that is feeding the fire to below fifteen percent to extinguish the fire by spraying, via the second end orifice only of the plastic pipe, by the fire fighter without using drones, carbon dioxide gas only from the one cylinder into, on or around a burning building, house or apartment, wherein carbon dioxide gas remaining after the fire is extinguished flows to lower levels of the building, house or apartment; and
blowing the remaining carbon dioxide gas out of the lower levels so people can breathe in the lower levels.
