Consider adding a standard for the use of FarUV (222nm) and/or near UV-C (254nm)

Oh fascinating, this is not something I had considered! My instinct is that this might be a better fit for suggestions in an Organizer Guide, rather than in a badging standard. Do you have some links I can dig into to learn more or incorporate directly into documentation?

Also: THANK YOU! For this and the other suggestions 💖

How technical and detailed do you want?

richterdavid commented 7 months ago

For near UV-C, there's this chapter from ASHRAE: https://www.ashrae.org/file%20library/technical%20resources/covid-19/i-p_a19_ch62_uvairandsurfacetreatment.pdf

Far UV-C is not yet integrated into air quality standards from organizations like ASHRAE, which tend to be more conservative. I'll find some sources for you.

Below are some recent papers on Far UV-C. Generally speaking, reasonable levels of exposure appear to be safe for humans, while reducing "live" virii by orders of magnitude. Effects on bacterial and fungi are more variable, with some susceptible and others not.
