These exit signs offer directional guidance to exits or exit passageways. Use the appropriate arrows to indicate direction of travel to intermediate doors, corridors, or stairwell exits where the fastest egress direction is unclear. BradyGlo& photoluminescent signs provide a bright, long-lasting afterglow during a lights-out evacuation. Maximum charge is achieved in two hours with 2 foot-candles of bright white light. BradyGlo& photoluminescent materials are non-toxic, non-radioactive, and washable, and prevent flame spread. Each sign measures 5 in. x 14 in. Designed to meet or exceed all NYC Local Law 26 requirements.
