The system includes a reservoir for containing a supply of clean fire inhibiting liquid chemical (CFIC) liquid for spray application over over the interior surfaces of raw and treated lumber and sheathing used in a completed section of a wood-framed assemblies in a wood-framed building during its construction phase; a liquid spray pumping subsystem operably connected to the reservoir tank containing the supply of CFIC liquid. A hand-held liquid spray gun, operably connected to the liquid spray pumping subsystem, is used to for spray CFIC liquid from the reservoir tank onto the exposed interior wood surfaces of lumber and sheathing used to construct each completed section of the wood-framed building, to form a CFIC coating on the treated interior wood surfaces providing Class-A fire-protection to the completed section of the wood-framed building. ## Claims ### Claim 1 A system for producing wood-framed buildings having Class-A fire-protection against total fire destruction during construction phase, and for marking and certifying the same, said system comprising: a reservoir for containing a supply of clean fire inhibiting liquid chemical (CFIC) liquid for spray application over over the interior surfaces of raw and treated lumber and sheathing used in a completed section of a wood-framed assemblies in a wood-framed building during its construction phase; a liquid spray pumping subsystem operably connected to said reservoir tank containing said supply of CFIC liquid; a hand-held liquid spray gun, operably connected to said liquid spray pumping subsystem, for spraying CFIC liquid from said reservoir tank onto the exposed interior wood surfaces of lumber and sheathing used to construct each completed section of said wood-framed building, so as to form a CFIC coating on the treated interior wood surfaces providing Class-A fire-protection to said completed section of said wood-framed building; and apparatus for visually marking and certifying that exposed interior wood surfaces of each completed section of said wood-framed building construction have been properly spray-coated to provide Class-A fire-protection within said completed section of said wood-framed building. ### Claim 2 A system for producing wood-framed buildings having Class-A fire-protection against total fire destruction during the construction phase, said system comprising: a reservoir for containing a supply of clean fire inhibiting liquid chemical (CFIC) liquid for spray application over over the interior surfaces of raw and treated lumber and sheathing used in a completed section of a wood-framed assemblies in a wood-framed building during its construction phase; a liquid spray pumping subsystem operably connected to the reservoir tank containing the supply of CFIC liquid; a hand-held liquid spray gun, operably connected to the liquid spray pumping subsystem, for spraying CFIC liquid from the reservoir tank onto the exposed interior wood surfaces of lumber and sheathing used to construct each completed section of the wood-framed building, to form a CFIC coating on the treated interior wood surfaces providing Class-A fire-protection to the completed section of the wood-framed building; wherein said CFIC-coated wood surfaces suppress fire ignition and suppression by interfering with free radicals (H+, OH—, O—) produced during the combustion phase of a fire; and apparatus for visually marking and certifying that exposed interior wood surfaces of each completed section of said wood-framed building construction have been properly spray-coated to provide Class-A fire-protection within said completed section of said wood-framed building. ### Claim 3 A method of producing wood-framed buildings having Class-A fire-protection against total fire destruction during the construction phase, comprising the steps: (a) providing a reservoir for containing a supply of clean fire inhibiting liquid chemical (CFIC) liquid for spray application over over the interior surfaces of raw and treated lumber and sheathing used in a completed section of a wood-framed assemblies in a wood-framed building during its construction phase; (b) providing a liquid spray pumping subsystem operably connected to the reservoir tank containing the supply of CFIC liquid; (c) using a hand-held liquid spray gun, operably connected to the liquid spray pumping subsystem, for spraying CFIC liquid from the reservoir tank onto the exposed interior wood surfaces of lumber and sheathing used to construct each completed section of the wood-framed building, so as to form a CFIC coating on the treated interior wood surfaces providing Class-A fire-protection to the completed section of the wood-framed building; and (d) visually marking and certifying that exposed interior wood surfaces of each completed section of said wood-framed building construction have been properly spray-coated to provide Class-A fire-protection within said completed section of said wood-framed building.
