A 2013 article published in the Journal of the American Medical Association (JAMA) concluded carbon monoxide (CO) diffuses across single-layer gypsum wallboard, double-layer wallboard, and painted double-layer wallboard. This work has possible impacts on current model building/fire
code provisions that stipulate CO detection is not required if there are no "communicating" openings between a garage and the dwelling unit, sleeping unit or classroom. The objective of this research is to provide information to the Technical Committees of NPFA 720, Standard for the Installation of Carbon Monoxide (CO) Detection and Warning Equipment, NFPA 101, Life Safety Code, and NFPA 5000, Building Construction and Safety Code, that may serve as the technical basis for guidance on additional CO detection location requirements.
