During emergency evacuation of common buildings and facilities, often building occupants can be subjected
to various hazards such as Fire, Smoke, Explosion, Obscuring debris, and possible power failure.
As current fire safety system of the common facilities and buildings are commonly dependant on emergency
electrical power. In the event of a backup power failure or damage to the electrical system, or if the emergency light
are obscured by smoke and fallen debris, the occupants evacuating the building can be in grave danger.
SafeSIGN has developed a versatile solution to complement the existing electrical emergency backup systems,
to provide reliable evacuation guidance for building occupants, independant of electrical backup power.
The Technology
SafeSIGN utilizes a special high-performance phosphorescent pigment (Strontium Aluminate) that is capable
of absorbing light from all common light sources and store this energy within its material structure very much like a rechargable
battery.
SafeSIGN converts previously stored energy back into light, resulting in a fully-illuminated sign independent
of any light source for hours under total darkness.
SafeSIGN is non-radioactive, non-toxic, chemically and thermally stable, and environmentally friendly. It
can be fully charged in as little as 10 minutes, and stay charged until the surrounding darkens. It can be charged
for an unlimited number of time, and has no memory effect for recharging, as commonly found in rechargable
batteries.
