Ed,
If you smell Hydrazine, MMH, or UDMH you are over the short term toxic
exposure limit for carcinogenic chemicals. I developed electronic gas
sensors to detect these vapors at <1 PPM for Titan launch facilities.

What is the relation of "Smell" threshold to "Danger" threshold for this?
If the danger threshold is less than the smell threshold (dangerous
before you can smell it) smelling it would be a bad thing.
I had thought N2H4 was like that, but it might be N02 instead.

I doubt I ever met him in The Netherlands. Bottled aqueous hydrazine
N2H4 solution smells like ammonia.
