UVC is highly carcinogenic. You don't want to be exposed to anything that emits it, even for a few minutes. It can also burn your corneas and cause blindness. UVC doesn't occur naturally on Earth because it is filtered by the ozone layer, scattered by the Rayleigh effect, and absorbed by oxygen gas. Metal halide bulbs, which are mercury vapor bulbs, do produce UVC, although they have a coating to absorb most of this spectrum. I was mistaken in earlier posts, confusing halogen with metal halide. Yes, you do not want to be in close proximity to metal halide bulbs, not only because of some UVC emission but also due to their intensity in the UVB and UVA spectrum.
