I once fitted UV lamps in the beer cellar of a public house. Mould was an ongoing problem and chemical treatment avoided lest it taint the beer.
To avoid dangerous exposure to persons, several safety systems were used.
Firstly, a two way switch only lit the UV lamps when the ordinary lighting was turned off, and secondly presence detectors disabled the UV lights if anyone was in the cellar.
A duplicated warning sign was also lit outside the beer cellar "DANGER ULTRAVIOLET LIGHT WITHIN. NO ENTRY" When the UV was on.
I removed it when the publican retired, not trusting unknown persons to use it safely.
