The Assembly Letter B 4872 sign must be displayed at the correct designated location. People should already know to head for this safe area and will be reassured of their safety by the fact that this sign is visible.
The sign will carry on being visible to people even if there is no lighting, as being photoluminescent it will glow in the dark. To ensure people are at assembly point B, use this sign to advise them accordingly.
Fixing requires anything as simple as sticky pads, 'No-nails' type adhesive or double-sided tape.
