If your workplace works through the night or in the case of a “lights out”” emergency, Photoluminescent Health and Safety Signs will keep your health and safety procedures visible. These glow in the dark Health and Safety signs can be seen in total darkness. They only need to take in visible light for 10 - 30 minutes to produce 6 hours of illumination. Our extensive range of Photoluminescent Health and Safety Signs including important signs like Caution, Beware of Step, Warning Toxic, and Danger Explosive Atmosphere can be bought directly online. Or contact us if you can’t find what you need. Our in-house design team designs 100’s of signs to order a day, they’re ready to discuss any custom and personalisation requirements.
