Please, don=92t underestimate the danger of mercury vapour!
Mercury vapour is dangerous, and it is difficult to clean up indoor spills completely. Even the 5 mg Hg from a crushed light bulb indoors can create dangerous air concentrations, as many publications have shown. The saturated air concentration at room temperature is about 15 mg Hg/m3. That concentration is 500 times higher than the TLV, and such exposures have resulted in serious intoxications.
