## Abstract

A cloud-based system for verifying and documenting Class-A fire-protection treatment of a wood-framed building using on-site spraying of a clean fire inhibiting chemical (CFIC) liquid. The system includes (i) a data center with web, application and database servers for supporting a web-based site for hosting images of certificates stamped on spray-treated wood surfaces, and other certification documents, and (ii) mobile smart-phones used to capture digital photographs and video recording of spray-treated wood-framed building sections during the on-site fire-protection spray process, and upload the captured digital images to the data center, for each spray treatment project, so that insurance companies, builders, and other stakeholders can review such on-site spray completion certifications during the building construction phase of the wood-framed building.

(b) after each said completed wood-framed building section has been spray coated with said CFIC liquid, posting fire-protection certifications in said completed wood-framed building section as being spray coated with said CFIC liquid and provided with Class-A fire-protection;
(c) before applying wallboard and/or other wall board covering over said spray-coated completed wood-framed building section, using a first mobile computing system to capture and collect digital photographs and/or videos of fire-protection certification postings in said spray-coated completed wood-framed building section;
(d) using said first mobile computing system to upload to a central database on a wireless information network, said captured digital photographs and/or videos of fire-protection certification postings in completed wood-framed building sections, and Class-A fire-protected status information indicating that said completed wood-framed building sections have been spray coated with said CFIC liquid and provided with Class-A fire-protection, along with said Class-A fire-protected status information, and
(e) upon the outbreak of a fire in said wood-framed building, using a second mobile computing system to remotely access said central database and determine the Class-A fire-protected status of specific completed sections of the wood-framed building provided by the CFIC liquid spray treatment of said wood-framed building sections during the construction phase, and instantly inform firefighters arriving on the job site location, and tasked with fighting said fire outbreak, that specific completed wood-framed building sections have been treated with Class-A fire-protection during said construction phase.

### Claim 18

A method of protecting a wood-framed building against fire while under construction on a job site location in accordance with a wood-framed building project having a construction phase, said method comprising the steps:
(a) delivering to said job site location, a liquid spraying system operably connected to a supply of a clean fire inhibiting chemical (CFIC) liquid, for spraying over all interior exposed wood surfaces of each completed section of a wood-framed building being constructed during said construction phase, so as to provide Class-A fire-protection over all of the wood surfaces sprayed with said CFIC liquid;
(b) deploying a first mobile computing system on said job site location, including a mobile application and a digital camera for capturing said digital images and/or video recordings of fire-protection certification postings in completed sections of the wood-framed building provided with Class-A fire-protection during said construction phase, and transmitting said digital images and/or video recordings to a central database on a wireless network, so as to document Class-A fire-protection of the wood surfaces in said completed wood-framed building sections;
(c) after completing each said wood-framed building section during said construction phase, where wood framing has been constructed and sheathing installed, but before any wallboard or wall board covering has been installed, spraying a clean fire inhibiting chemical (CFIC) liquid from a liquid spraying system, as a spray coating, over all exposed interior wood surfaces in said completed wood-framed building section so to provide Class-A fire-protection to and over each completed wood-framed building section;
