Well, gasoline isn't exactly a benign substance, either. It would be interesting to compare the number of people burned to death in gasoline fires to those poisoned by ammonia vapor. My gut tells me that gasoline is currently responsible for more fatalities, but I don't have any hard facts on that. Of course the number of ammonia deaths would go up to some degree if it were used in cars, but that would be offset by fewer gasoline deaths.
