Although impure liquid hydrazine doesn't explode, it can certainly boil vigorously and spray hot and chemically toxic liquid around, which can endanger the safety of people nearby.

不纯液肼虽然不会爆炸，但肯定会剧烈沸腾，并向周围喷出炽热化学毒性液体，危及附近人员安全。

This is not it though; if ammonia is present in excess in the mixture, it can also produce toxic and potentially explosive liquid hydrazine.

但这不是问题所，氨混合物中过量存，它也会产生有毒和潜爆炸性液体肼。
