Abstract
Delivery of pelletized carbon dioxide (dry ice) to a target material from a distance, by projection, spraying, or aerial dropping the pelletized carbon dioxide onto the target material using gravity. Delivery may be made by a mobile apparatus. The types of target material with which the present invention is designed to apply may include, e.g., hydrocarbon material, hazardous material, burning material, and the like. The carbon dioxide may be pelletized to diameters in a size range of about 3 mm to 100 mm.
Claims2
A fire and/or hazardous material abatement support structure for applying carbon dioxide pellets of a diameter greater than 3 mm to a fire and/or hazardous material, comprising:
- a pelletizer disposed on the support structure producing carbon dioxide pellets having a diameter greater than 3 mm and configured for connection to a source of liquid carbon dioxide;
- a storage device disposed on the support structure storing the carbon dioxide pellets having a diameter greater than 3 mm;
- and
- a delivery device disposed on the support structure projecting or spraying the carbon dioxide pellets having a diameter greater than 3 mm, wherein the delivery device utilizes a source of nitrogen projecting or spraying the carbon dioxide pellets having a diameter greater than 3 mm, so that the support structure distributes pellets used to extinguish a fire and/or contain a hazardous material.
