Abstract

Fire prevention and suppression systems and breathable fire-extinguishing compositions are provided for rooms, houses and buildings, transportation tunnels and vehicles, underground and underwater facilities, marine vessels, submarines, passenger and military aircraft, space stations and vehicles, military installations and vehicles, and all other human occupied objects and facilities. The system provides a breathable hypoxic fire-preventative atmosphere at standard atmospheric or local ambient pressure. The system employs an oxygen-extraction apparatus supplying oxygen-depleted air inside a human-occupied area or storing it in a high-pressure container for use in case of fire. A breathable fire-extinguishing composition is introduced for constant fire-preventive environments, being mostly a mixture of nitrogen and oxygen and having oxygen content ranging from 12% to 17%. A fire-suppression system is provided employing a fire-extinguishing composition with oxygen concentration under 16%, so when released it creates a breathable fire-suppressive atmosphere having oxygen concentration of approximately 16% (or lower if needed) with possible addition of carbon dioxide. A technology for automatically maintaining a breathable fire-preventive composition on board a human-occupied hermetic object is provided by introducing inert ballast that automatically maintains oxygen content under the Hypoxic Threshold. An aircraft fire prevention and suppression systems are provided utilizing hypoxic fire extinguishing compositions for producing breathable atmosphere onboard having fire-retarding properties.

Description

[0001] This application is a continuation in part of U.S. Ser. No. 09 / 551026 "Hypoxic Fire Prevention and Fire Suppression Systems for computer rooms and other human occupied facilities", filed Apr. 17, 2000, U.S. Ser. No. 09 / 566506 "Fire Prevention and Fire Suppression Systems for computer cabinets and fire-hazardous industrial containers", filed May 8, 2000 and of U.S. Ser. No. 09 / 750801 filed Dec. 28, 2000 "Hypoxic Fire Prevention and Fire Suppression Systems and Breathable Fire Extinguishing Compositions for Human Occupied Environments".

[0002] This invention is related in part to preceding U.S. Pat. No. 5,799,652 issued Sep. 1, 1998.

[0003] The present invention introduces the method, equipment, and composition of fire prevention and suppression systems that utilize a low-oxygen (hypoxic) environment to:

[0004] Instantly extinguish an ongoing fire

[0005] Prevent a fire from getting started.

[0006] With its mode of action based on the controlled release of breathable fire-suppressive...
