The Stairway Level A 4871 Sign will be used either on a stairwell or a lift shaft, to inform people that they are on this level. This will help to eliminate any confusion. The sign has a white letter A, on a green background and people should already be used to seeing this type of sign.
It is a good idea to use these signs on each level. If there were an emergency and the lights went out, the sign would continue to glow, as it is Jalite AAA photoluminescent.
Fixing requires anything as simple as sticky pads, 'No-nails' type adhesive or double-sided tape.
