Dimethylmercury can kill you from merely inhaling the fumes
____________________________________________________________
Is this the same mercury that is in the new improved government light bulb?
No it isn’t. Not possible to use something that rates a “4” on both the “health” and “flammability” NFPA 704 chart in something like a light bulb anyhow; heat source would make it explode too readily, that is if the fumes don’t kill you first. The CFLs contain elemental mercury, which is bad enough although not acutely poisonous (all fluorescent lights have mercury vapor, BTW, even the long tubes).
You shouldn’t worry so much — it is an IMPROVED government lightbulb.
Just watch those congresscritters scramble when these improved lightbulbs happen to get damaged. They probably insist on having the conventional lightbulbs in their offices.
