House Fire Fighting Technique

Abstract

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.

Claims

1. The use of powder or pellets or flakes of Dry Ice to control or extinguish house, apartment, condo and building or other fires by throwing, spreading, dumping or spraying them into or around or on the fire scene or in, on or over or around the house or building.

2. The use and constructing or manufacturing of Drones as shown in FIGS. 5 and 6 (drones to spread Dry Ice), FIGS. 7 and 8 (drones to spray Dry Ice), FIG. 9 (drones to spray Carbon Dioxide gas) and FIG. 11 (drones to dump Dry Ice) and any similar drones that can carry Dry Ice and Carbon Dioxide gas to be spread or sprayed remotely.

3. The use of Carbon Dioxide Gas from cylinders carried by firefighters (people) or by drones, or by fire trucks to spray into, on or around a burning building/house/apartment to extinguish the fire.

4. When Carbon Dioxide gas is sprayed into a building as in claim 3, if the pipe carrying the Carbon Dioxide gas needs to be longer, it should be supported by a long rigid pole or the spray end of the pipe to spray Carbon Dioxide gas should be carried by a drone to higher places.

5. The use of fans or leaf-blowers to blow off the excess Carbon Dioxide through windows, doors or openings after the fire is extinguished as in claim 3.

DESCRIPTION

[0071] 1. Dry Ice and Carbon Dioxide cylinders can be carried in bulk to where the fire is burning. [0072] 2. If it is possible to throw the Dry Ice into the building by the firefighters, powder of Dry Ice can be put on the plastic sheet (FIG. 3) and the circular edge must be collected into bunch and the Dry Ice packs (FIG. 4) are carried in plastic containers (For example: FIG. 1 and FIG. 2). Dry Ice packs must not be tied up. The packs can be thrown by the firefighters into or around the building. Since the plastic sheets are not tied by strings, once it hit the floor, Dry Ice will spread out which enables it to sublimate more easily. [0073] 3. If firefighters decide that it is better to have the drones carry the Dry Ice packs into the building, there are six kinds of drones to do that. (FIG. 5, 6, 7, 8, 9 and FIG. 11.) Since the drones have cameras, the operators can direct them as close as possible to the fire before dropping/spreading/spraying/dumping the Dry Ice remotely. Drones should have holes to let Carbon Dioxide gas escapes. [0074] 4. Payload Release Mechanism can be controlled remotely to drop Dry Ice pack. [0075] 5. First drone in FIGS. 5 and 6 has two openings for Dry Ice to drop. Both openings are controlled to open or close separately. The fan underneath is to spread the Dry Ice that drops onto it. The fan will spread the Dry Ice that drops from one opening to one side and from the other opening to the other side. By closing one side, the other side will spread Dry Ice to only one side of the drone. [0076] 6. Second drone in FIGS. 7 and 8 has only one opening in the bottom for Dry Ice to drop into the pipe to spray it. The air pump will push it out to spray it towards the fire. [0077] 7. Third drone in FIG. 11 is to carry Dry Ice and dump as much as one wants by controlling the door. [0078] 8. If needed, the drones can be controlled to come out and refill again. [0079] 9. There are three ways to spray Carbon Dioxide into a building that is burning: from one or two cylinders that a firefighter is carrying (FIG. 10), or from drones carrying Carbon Dioxide cylinders (FIG. 9), or by using a plastic pipe directly coming from a fire truck carrying a bigger Carbon Dioxide cylinder. If fire is too big, one firefighter can hold two spray pipes coming out of two cylinders at the same time. [0080] 10. If the fire is in a room several floors up, the spray pipe can be carried by a drone to spray into the opening. If firefighter has oxygen tank, he can go inside to spray. [0081] 11. After the fire is extinguished. fans or leaf-blowers are used to blow off the remaining Carbon Dioxide in the house or building for people to safely enter it.
