ammonia is useful, but and at the same time, and his risk of ammonia inhalation has a lot of harm to human body this is what we already know, so ammonia inflammable and explosive?
Ammonia does not burn in air. It burns in pure oxygen, so ammonia is not flammable.
But when ammonia and air mix, the explosion limit is 16% ~ 25%, the most easy ignition concentration is 17%.
The concentration at which the maximum explosive pressure was generated was 22.5%.
