Not an expert at that, but for the hood I'd go with a full face supplied air respirator. While it's unlikely there is anything volatile remaining, OsO4 attacks the corneas and I would not rely on a cartridge which probably has not been tested against Os4.

Hi everyone,
I'd like to know if anyone has dealt with the demolition of a lab and removal of a fume hood in which osmium tetroxide was used? Other than recommending respiratory protection (N100 or P100 cartridges), nitrile gloves and coveralls during tear-out, are there any other precautions we should keep in mind?
Thanks for any suggestions.
Ellen
