The current upper limit on hydrazine concentration in the air is 0.01 ppm.
Handling of open containers of even 35% N2H2 (commercial grade) solutions
leads to concentrations hundreds of times in excess of this limit, and
requires personnel to be fully dressed in protective rubber suits &
respirators. Its a "suspected carcinogen."
Also, N2H2 has been used in the past as a "monopropellant" in rockets,
similar to hydrogen peroxide, but is much more toxic...
