Photoluminescent tapes & markings for escape routes, danger zones and more

Why do you need photoluminescent markings?

Photoluminescent floor markings in industrial and warehouse areas for escape routes are an extremely important safety measure to ensure quick and efficient action in the event of an evacuation. They are used to give escape routes a clearly defined structure and enable employees to find their way out even in dark or smoky environments.

How long does photoluminescent marking last?

As a rule, photoluminescent material can remain illuminated for up to several hours after charging. It does not matter whether the light source is sunlight or artificial lighting.

What is the difference between fluorescent and phosphorescent?

The main difference between the two lies in the duration for which the material continues to glow after absorbing light.

Fluorescence describes the process by which a material absorbs light and immediately emits it again in the form of visible light. The emission ends as soon as the material is no longer exposed to the stimulating light. This means that the luminosity only lasts as long as the light acts on the material.

Phosphorescence, on the other hand, describes the process in which a material absorbs light and emits this light again over a longer period of time, even if the stimulating light is no longer present. The phosphorescent material can therefore continue to glow for some time after the light source has been switched off.

Why is photoluminescent floor marking important?

Photoluminescent material enables good visibility even in the dark or in smoke. As smoke rises, markings on the ground are visible for the longest time. In emergency situations, it is important that people can quickly and safely find their way to exits, emergency exits or emergency equipment. Photoluminescent markings can serve as orientation points and facilitate the escape route. They can also serve as visual communication tools to convey important information or instructions in emergency situations. For example, they can be used as signs for steps, directional information, danger areas or escape routes. Such markings are also independent of electricity.

How do photoluminescent floor markings work?

Photoluminescent floor markings, also known as phosphorescent floor markings, are based on a phenomenon called phosphorescence. The floor covering or paint contains special pigments that are charged by light energy when exposed to light. The pigments consist of luminescent materials. When charged with light energy, light emission occurs, which is known as afterglow. This afterglow serves as a visual marker for orientation or to emphasise danger spots. It should be noted that photoluminescent floor markings do not produce any light of their own, but merely emit the absorbed light in the form of afterglow. They are therefore particularly effective in dark environments where there are few or no light sources.
