Covid - 19 Lighting Solutions

Hi all (In particular health care experienced engineers)

I am reading that many Lighting manufacturers are looking at the introduction of UV-C Type lighting maybe used for wheeling into rooms following Covid 19 exposure within an infected room. Once the infected person has left the room then the lights can be wheeled in and switched on from outside the room or via a timer and left in situ which in theory kills the virus. In theory like a fumigation process using Lighting. I know these type of lights can be dangerous and they cause temporary damage to the cornea if observed directly and UV-C is also a carcinogen for human skin. Obviously installed in a controlled environment with limited/no exposure time is the golden rule here using these lights which must have a safe purification wavelength. Does anyone have any guidance on this as personally i think it should come from Public Health ?

  • REHVA have a document regarding Building Services which states nothing about Lighting - REHVA procedures are as follows:


    Summary of practical measures for building services operation

    1. Secure ventilation of spaces with outdoor air

    2. Switch ventilation to nominal speed at least 2 hours before the building usage time and switch to lower speed 2 hours after the building usage time

    3. At nights and weekends, do not switch ventilation off, but keep systems running at lower speed

    4. Ensure regular airing with windows (even in mechanically ventilated buildings)

    5. Keep toilet ventilation 24/7 in operation

    6. Avoid open windows in toilets to assure the right direction of ventilation

    7. Instruct building occupants to flush toilets with closed lid

    8. Switch air handling units with re-circulation to 100% outdoor air

    9. Inspect heat recovery equipment to be sure that leakages are under control

    10. Switch fan coils either off or operate so that fans are continuously on

    11. Do not change heating, cooling and possible humidification setpoints

    12. Do not plan duct cleaning for this period

    13. Replace central outdoor air and extract air filters as usually, according to maintenance schedule

    14. Regular filter replacement and maintenance works shall be performed with common protective measures including respiratory protection
