The presidency says: The project is an innovative device to sterilize the handrails (handrails) of escalators inside the Sacred Mosque, using ultraviolet (UV LED), where the device works to convert kinetic energy into electrical energy without the need to make electrical connections.
According to the project’s organizers, the device works to sterilize throughout the ladder movement, eliminates the DNA molecules of the bacteria, and the wavelength of radiation is (278) nm, and that these radiation have no harmful effect on human health.
The presidential statement said: The results of the experiment of samples confirmed the reduction of the number of bacterial colonies from 160 colonies to 10 bacterial colonies, which means that the device is able to eliminate the spores created on the stairs by up to 94%.
