I would suggest reviewing the ACGIH Documentation of the TLVs for Osmium Tetroxide which reviews the data from which its TLV or BEI is derived instead of relying upon simply reviewing other college/university information. I’m going from memory hear only, but I thought that while the chemical properties of osmium tetroxide need respected, the real hazard came from occupational exposure. I try to focus on peer reviewed or government peer reviewed sources, e.g., OSHA, EPA. Colleges/universities are better sources than simply the internet, but they are not peer reviewed, nor citable in an affirmative defense. We have several J.D.’s on the list, please let me know if I am wrong, I’m always looking to learn.
I’m currently working on Chemical SOPs.
While working on Osmium Tetroxide I’ve been looking at other SOP’s from other Colleges/Universities and many say it is a strong oxidizer. Which makes sense but when you look at the SDS sheets and in particular the GHS for this chemical; oxidizer isn’t listed as a hazard. I’m looking at it in a solution and by itself (100%) and still no oxidizer warning.
Any guidance would be greatly appreciated.
