If you want to do this as a successful company, you essentially have to get your customers to trust you that you are installing it in a way where UVC up does not produce any negative effects.
People have been doing it for decades is not something that would convince me that there are not long-term side-effects.
The way you demonstrate that there are not long-term side effects is that we have very accurate ability to measure UV, and so you can show that the system being on vs off has a negligible impact on the amount of UV where people are. Long-term impacts would be downstream from this kind of easily detectable effect.
(I think this is very different for far UV, where you intentionally shine it in a way that does include the people. That is potentially a much better approach, because you can clean the air between people instead of only above them, but while the research on far UVC safety looks pretty good to me, it’s a much harder system to gather safety evidence on.)
