Public Input No. 41-NFPA 2001-2018 [ Global Input ] Type your content here ...Annex F Pure N2 Nitrogen Performance and Applications How a cloud of cohesive, pure, inert, cryogenically cold to start, N2 Nitrogen ends fires Evaporated from liquid Nitrogen which is a liquid clear as water but flows like Mercury, the Nitrogen gas cloud has the same affinity for its own molecules as the liquid allowing it to form a transparent space in a smoke-filled environment by displacing Oxygen, water, Carbon dioxide, toxins, and smoke particles thus staying pure and transparent. This cloud ends the flames because there is no Oxygen where the cloud exists. And starting at cryogenic temperature, -195.8oC., it cools the fuels. The original size of the cloud is 230 times the volume of the evaporated liquid. As it cools the fuel, it expands to 250 times the liquid volume at ambient temperatures and heating to inferno temperatures it becomes 600 to 700 times the volume. The volume increase causes the cloud to be lighter weight so it rises in the air. As the winds in the fire exist, it is wind driven. The winds move it cross-wise and the cooling causes it to rise upward. As the cloud of evaporated Nitrogen moves, it stays together, not losing volume and not being dissipated because of its inertness as N2, double Nitrogen molecules. Where the cloud has been, no flames exist unless or until the cooled fuels which, still within re-ignition temperature, start to flicker little flames. In outdoor fires including wildland fires and structure fires having escaping burning embers extinguished halts fire expansion. With the flames out, smoke production ends. With re-ignition, there is but a trickle of smoke until its expansion speeds up. Another Nitrogen application ends this fire. The area where the fire occurred, if controlled with evaporated Nitrogen clouds, has no residual material left by the fire suppressant since Nitrogen leaves the fire moving into the air where it mixes with the atmosphere which has 78% (N2)Nitrogen content. Recovery is limited to replacing what burned away, melted, warped or charred. One finds no water damage, no electrical arcing leaving electrical and electronics equipment functional unless it was in the fire. Food, paper and fabrics not in the fire are in usable condition and can be eaten, worn, walked on, sat upon and used. The smell of smoke is removed using Febreze ™ (Proctor and Gamble). Stored liquid Nitrogen does dissipate in large cryogenic containers at 1% per day and in smaller units as much as 10% per day. This going cost of replenishment assures less loss were a fire event to occur, less recovery time, and possibly lower insurance rates. Nitrogen use also can handle crises events as spills, overheating, and flooding. This evaporated Nitrogen as a fire suppressant differs from all other means of fire control because it is the only cohesive cloud. Helium, Neon, Argon, and even compressed Nitrogen gas also are inert, but they form no cohesive clouds, but rather lower the Oxygen percentage in the air by mixing with the air when released in the pure state. Other molecules as carbon dioxide dissipate by photosynthesis or, in the case of water, condensing making clouds and wetting things down and dissolving salts. In fire fighting as water puddles it is useless in fire control. Also, below 0oC. water is ice which must be melted to be useful. Water is a fire suppressant as a liquid or extremely o hot steam. Nitrogen (N2), a gas from -195.8 C through inferno temperatures, always displaces Oxygen and other atoms and molecules which ends flames, and cools fuels that are hotter than the Nitrogen gas encountered. As it cools, Nitrogen gas warms expanding its volume and making the cloud ride higher and higher in the air space. When it escapes the fire and cools to match the air, it mixes into the atmosphere sustaining the 78% Nitrogen level. The Nitrogen had been removed from the atmosphere in the liquefaction process. After fire use, it is returned. Evaporated Nitrogen does not reduce air Oxygen ratio as other gas fire suppressants do. It displaces Oxygen and stays pure pushing Oxygen aside, ending flames. Finally, the term rain was defined in the patent process for the Liquid Nitrogen Enabled, patent USP 7,631,506 as releasing liquid Nitrogen through perforated pan, cap or trough, as falling by gravity. My patent attorneys, the late, brilliant Christopher J. Kukowski and Jim Boyle of Boyle Fredrickson 3 of 371 1 of 176 3/15/2019, 10:45 AM National Fire Protection Association Report https://submittals.nfpa.org/TerraViewWeb/ContentFetcher?commentPar... SC of Milwaukee and examiner William C. Doerrler worked out the necessities for issuance. Falling by gravity, water falls as rain, snow, sleet, hail, compared to dew and frost which condense from water vapor onto solid items in the air. Liquid Nitrogen, as the patent states, falls as drops through a matrix of small holes by gravity creating the evaporated Nitrogen gas cloud as here described. We call this cryorain since the original cloud starts at liquid Nitrogen temperature as these drops fall and evaporate forming the evaporated pure Nitrogen N2 molecule, cohesive, inert, cryogenically cold cloud which retains purity by displacing all other gases and airborne particles and ending the flames as it moves in the fire rising as it warms when cooling the fuel. And use of Nitrogen here described saves the portion of fresh water normally expended in water fire control for community and agricultural applications. Patent USP7,631,506 covers all uses of evaporated Nitrogen and rights are in place until December 15, 2029. It is assigned to AirWars Defense lp and will be licensed to CryoRain Inc. where the short term transport and dispersing tools will be made. This evaporated Nitrogen adds both the thermal factor and its cohesive purity to handling crises ending fires instantly, stopping floods, solidifying spills to be skimmed up, preventing ordnance from exploding, and handling criminal situations saving all, restraining criminals and freeing innocents, preserving their homes and communities. This changes fire control, law enforcement and defense department practices. It reduces the migration levels as they flee the ruins in the Middle East. Ending coal mine fires in-situ does not disturb surface features and can halt sea level rise by year 2021. The fires ended no longer perpetually heat the earth's crust which cradles now cooled oceans so less snow mass melts, and tops the mountains allowing glaciers to grow. Freeze fracking oil shale and hot Nitrogen extracting fuel stops man made earthquakes, ends ground water contamination, and yields cleaner fuel and separating the fuel types at well locations. Our fresh water is preserved when Nitrogen is used in fighting fires.
