According to some of the earliest tests conducted by Chief Lloyd Layman of the US Coast Guard Firefighting School in the 1940s, fog nozzles perform better in battling fire than straight stream nozzles. The test consisted of 20 experiments in the engine room of a liberty ship. They released 5,000 to 7,000 gallons of fuel to create around 1,900 square feet of burning surface. The fire was allowed to burn for 30 minutes to achieve the worst possible fire situation. When the fog nozzle was used on the fire for a maximum of 40 minutes, it created steam which continuously decreased the temperature to below the flash point of the fuel.
Chief Layman found that the expanding steam pushed the un vaporized water particles throughout the room to burning areas beyond the immediate space of the nozzle. This process continued until all of the available atmospheric space was filled with steam, extinguishing the fire. More recent tests by Commander John. P. Fairly and the U.S. Navy agree with the findings of Chief Layman.
Water mist technology has gained acceptance over halon gas, in most cases. The following list contains current and future application for water mist fire protection technology as compiled by Factory Mutual Research, an affiliate of commercial and industry property insurer FM Global. FMR has noted that the effective fire fighting qualities of water mist have led to its use in a number of challenging fire protection applications.
Eugene Ivy, CEO of IFI and a 16 year veteran of the Port Arthur Fire Department in Port Arthur, Texas, is the inventor and patent holder of the technology behind the First Attack Nozzle and other products offered by IFI.
While employed by PAFD, Mr. Ivy was the Chief Mechanic where he maintained all fire vehicles for multiple fire stations and attended all fire calls. During that time he realized the need for a firefighting tool that would eliminate or reduce the need for firefighters to be burdened down with ladders, axes and saws in order to gain entry into different areas.
With that in mind, Mr. Ivy designed a nearly indestructible nozzle that gives firefighters immediate access into a structure (house, business, vehicle, boat, aircraft, cargo containers, etc.) via a stainless steel piercing tip. In addition, the patented and phenomenally unique rotor technology of the nozzle provides firefighters with a superior water shield unlike any on the market and has the ability to extinguish fires in a fraction of the time that conventional nozzles usually require.
New technology for an old adversary: International Fog, Inc. addresses the most compelling needs of fire departments across the country: Declining volunteer base, safety, speed and reducing equipment needs.
IFI's First Attack Nozzle reduces radiant heat by 90%, providing a superior shield for firefighters. Allowing for complete confidence when approaching a valve shutdown or during search and rescue.
