A tablespoon of anhydrous ammonia in a sealed 10x10x8 room is immediately dangerous to life and health. (Industrial refrigeration mechanics scoff at this. Most can no longer smell ammonia, or anything else for that matter!)
On the positive side, it is a natural refrigerant, just like water.
It is being used more and more for different uses than the traditional industrial refrigeration.
One nice thing about it is that it is incredibly cheap.
One bad thing about it is it's toxic nature. Insurance companies have jacked the cost of insuring ice rinks cooled with ammonia refrigerants. The results have been interesting as the industry has worked to minimize refrigerant charge to reduce the risk the insurance companies face.
We replace refrigerants with those that do not have an equal refrigerating effect.
This means the machine is not as efficient as it could/should be.
This means we burn more coal to make the power to make the machine run because the machine isn't very efficient anymore.
That make sense to you?
