I to inhaled! Hydrazine that is. My hydrazine experience was in the past and it was Unsymmetrical Dimethylhydrazine (UDMH), the really nasty stuff. It was while I was fueling Titan II missiles in the Kansas missile silos. Fortunately it wasn't enough to kill me but I'm sure it was just enough to make me a little bit crazy ;-) Have a great weekend!

If so, a lot of fluxes contain HBr, but very few of them contain hydrazine, at least regarding the ones we make. They are far more likely to contain amines, which are a lot safer. Additionally, amines are a lot cheaper than hydrazine. BTW, I've inhaled hydrazine in the past, not during the 15 years I've been at Cookson.
