Proximity and gesture sensing using IR LEDs can help with social distancing and enable contactless interactions with various types of equipment. On the other hand, UV-C radiation – the shortest group of wavelengths in the ultraviolet spectrum – has valuable virucidal properties. UV-C irradiation is used in various applications for sterilisation and disinfection, and has been shown to be effective against known coronaviruses, such as SARS. But let’s think carefully before going full-speed ahead…

Are UV LEDs safe to use?
The energy in UV-C is harmful to organic tissue in general, so we must give due consideration to safety. If people are likely to be in the vicinity when UV-C radiation is active, exposed skin may be affected. If UV-C reaches more delicate areas, by entering the eye, for example, there is potential for serious damage. In addition to protecting users and any others who may be nearby, equipment vendors need to be able to protect themselves by demonstrating that risks have been duly considered. The design, user instructions and any stipulated safety precautions must be
adequate to ensure acceptable safety.
