The PSPA established and maintains recognised industry standards for photoluminescent classification of safety products used in safety way guidance systems. Performance is split across 4 classes and graded on a photoluminescent’s luminosity (ie the amount of light it emits) and the duration over which it remains effective.

Glo-Brite® photoluminescents from Innova Solutions and your glow in the dark safety egress materials will meet or exceed PSPA photoluminescent classification standards.

Photoluminescent Classification:

• Class A – Cost effective photoluminescence.
• Class B – High performance in bright lighting conditions.
• Class C – High performance under low lighting conditions.
• Class D – Very high initial performance, with photoluminescence remaining good for up 60 minutes.

Whilst there is no legislation preventing the use of Class B for photoluminescent signage, the PSPA recommends Class C as the minimum requirement for emergency wayfinding signage. For an ISO 16069 compliant Safety Way Guidance System, all signage and components should be a minimum of Class C.
