House fire fighting technique

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.

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.
