PowderLight / Emergency Signal

PowderLight
PowderLight

PowderLight is a hand-held device that helps victims signal their location with brightly-colored powder.
Victims trapped in buildings or debris can activate the PowderLight. This propels brightly-colorer powder for emergency response teams to see. The powder remains in the air and does not float with smoke.
