Here's a rule of thumb for osmium: if you can smell it, it is fixing you!
(from experience - it smells a bit like chlorine). And if yo can smell it,
your eyes are in danger - that is the primary concern for osmium. You are
much better off using a true fume hood.

Subject: [Histonet] Osmium Tetroxide Protocol



Hi Histonetters,

When handling Osmium Tetroxide, is a chemical fume gard such as an Bench Top
fume absorber appropriate to use for this chemical?

Also, should you wear other PPE besides gloves, gown etc. Should you wear a
mask also?

Thank you.

Marsha Price
