Abstract:
A method of and system for on-job-site spray coating of clean fire inhibiting liquid chemical (CFIC) liquid all over the exposed interior surfaces of raw and treated lumber, sheathing and wood used in a completed section of a wood-framed assemblies in a wood-framed building during its construction phase. The system includes a liquid spray pumping subsystem having a reservoir tank for holding a supply of the CFIC liquid; and a hand-held liquid spray nozzle for spraying the CFIC liquid from the reservoir tank, over the exposed interior wood surfaces of lumber and sheathing used in a completed section of a wood-framed assembly in a wood-framed building during construction phase. The 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.
