Can't see much at the moment other than unsubstantiated claims and a few graphics. I too suffered from only slight exposure to ammonia when a reprographic machine went wrong in the next room and I was volunteered to shut it down. Massive headache, puking and had to be taken home. Yeah, anything can be dangerous so using phraseology used by someone in the great lithium battery debate on this site, "lithium batteries will catch fire", "ammonia hybrid fuel systems will leak or fail". I wonder how customers and insurance companies will cope with that.
