In the event of a fire or emergency, the visibility of standard emergency signs can often be impaired by poor lighting, smoke or even lack of power. In these cases our photoluminescent signs can provide a cost effective solution. Our signs use the internationally recognised British Standard symbols for escape routes (BS5499) like their standard counterparts. High intensity 1.3mm rigid material, tested to DIN 67510 Part 4 specification, which significantly exceeds the minimum Photoluminescent Safety Products Association (P.S.P.A.) Class 1 classification for brightness and longevity. Non-radioactive, non-toxic with no lead or phosphorous. Signs remain highly visible even in complete darkness. Factory applied self-adhesive backing.
