Why Are Photoluminescent Exit Signs Essential In Commercial Buildings?

By Essie Osborn


When choosing signage products for emergency exits, you need to ensure you get those which are effective and energy saving. The photoluminescent exit signs products are designed to counter the problems experienced with the traditional form of emergency signage. They work in complete darkness without the need for any source of light or energy. They absorb ambient light from the surroundings and store it.

There are many types of exit signage products you can get in the market and while some perform efficiently, others may be impaired by other underlying factors. The emergency signage products are useful in times of disasters. They aid people get out of buildings when disasters strike.

It is important that when disasters strike people in a building are able to escape fast. If there is no functional signage to lead them out, then it means they remain stranded in the premises. This can lead to disasters. People will panic when they cannot find the routes exiting buildings.

Since the traditional exit signs rely on a source of light from the electricity, gas, battery, or generator, they are likely to fail if none of those sources of energy is working. The photoluminescents use phosphor, a substance that is able to exhibit luminance when certain wavelengths of light strike it.

When there are no lights, these products glow and allow people to see the routes to get out of buildings. They can work in complete darkness requiring no external source of light. These signage products are not only important for the people trapped in buildings but also for the firefighters.

It is not sustainable to have signage products that cost a lot of money when indeed there are viable cost effective products in the market. Photoluminescent markers are designed to reduce the cost but yet important, enhance the visibility of the signage. In addition, they are non-radioactive meaning that they do not contain harmful elements that could harm people and the environment.

Besides, they are non-toxic and will help keep the environment safe. These forms of signage products produce an afterglow by discharging the light they have absorbed from the artificial and natural lights. Although the glow is not that brilliant, it offers people the ability to find their ways out of emergence situations.

People cannot be able to see anymore and the signage has to absorb light so that it works. The photoluminescent path markings are installed on areas such as stairwells, landings, and handrails as well as the doors where there are ways leading people away from a building. They help people in swift evacuations. These products should be installed by qualified technicians because they have to be fitted in the right locations for people to be able to see them in darkness.
