Abstract
An emergency egress system for a locus that is exposed to light in non-emergency use and susceptible to interruption or termination of light in emergency circumstances. The emergency egress system comprises a fibrous web deployed in the locus, wherein the fibrous web has photoluminescent fiber incorporated therein in sufficient amount and distribution to illuminate the web or predetermined portions thereof during the interruption or termination of light in emergency circumstances, and subsequent to light exposure thereof.
Claims19
An emergency egress system for a locus that is exposed to light in non-emergency use and susceptible to interruption or termination of light in emergency circumstances, said emergency egress system comprising a fibrous web deployed in said locus, wherein the fibrous web has photoluminescent fiber incorporated therein in sufficient amount and distribution to illuminate the web or predetermined portions thereof during said interruption or termination of light in emergency circumstances, and subsequent to light exposure thereof.
A kit comprising a multiplicity of different type carpet sections, for assembly of a carpet therefrom, wherein at least one of the different types of carpet sections comprises photoluminescent fiber incorporated therein in sufficient amount and distribution provide illumination during interruption or termination of light exposure, and assembly of the different type carpet sections produces a carpet having photoluminescent and non-photoluminescent regions.
A method of providing assisted egress from a locus that is exposed to light in nonemergency use and susceptible to interruption or termination of light in emergency circumstances, said method comprising providing in said locus an emergency egress system comprising a fibrous web, wherein the fibrous web has photoluminescent fiber incorporated therein in sufficient amount and distribution to illuminate the web or predetermined portions thereof during said interruption or termination of light in emergency circumstances, and subsequent to light exposure thereof, whereby said illuminated web or portions thereof aid persons viewing same in said emergency circumstances to visually determine a path to an exit from said locus.
