Hi Folks, We use a UV bulb in my workplace which contains deuterium gas. The bulb is safely contained within a housing unit inside a machine so there are no direct hazards with UV radiation etc. I was however wondering, what would happen should such a bulb break? I have checked some MSDS sheets on deuterium and it seems to be a flammable gas that can form explosive mixes with air. Does anyone know if the quanity of gas contained in a small bulb is safe? If the bulb broke upon replacement and released the gas - what would happen? Thanks.
