major accident with lights, I'm freaking out!

[lotusbird]

I can't believe this, this is my first post, not how I planned to join... I don't even know where to put this post so I'm sorry if it's the wrong place...
My husband was putting up a rod to hang my mounted orchids from, and he hit my 4 ft light shattering the tubes and spraying the orchids underneath with glass and white powder. I've since been googling and that white powder is phosphor, with maybe mercury in it! I did my best to get most of the glass out of the pots, though I'm sure theres still some microscopic pieces in the medium. I'm really freaking out about the powder though, these are t12 tubes and supposedly they have less mercury in them than CFLs do, but they were also new bulbs, which may contain more mercury than older b ulbs. What should I do? Several plants were COVERED, mostly the leaves, I rinsed them off carefully trying not to get any water/powder in the medium. Should I repot? There was about 25-30 plan ts under that light... I didn,t even know what that white powder was, so I just vacuumed the stuff up and then went to feed my parrots, OMG I might have poisoned them and my orchids too...Please, any advice greatly appreciated.
