The CO2 Protected Area 5000 sign clearly states that if people hear an alarm, they are to vacate the area immediately and close all exits behind them. If this sign is essential to your premises, display it prominently and it will continue to warn people even if there are no lights, as it is Jalite AAA photoluminescent.

Without displaying this sign, you may not be able to guarantee that all of these urgent instructions are followed.

Fixing requires anything as simple as sticky pads, 'No-nails' type adhesive or double-sided tape.
