Thats about 1 rail car full. Though lighter than air, it is a compressed liquefied gas and upon release it is extremely cold and dense and it flows across the ground carried by the wind until it heats up and rises and dissipates.. Pure ammonia (anhydrous) is a common refrigeration gas. Neutralize with water fog. Will burn lungs, skin, eyes, mucous membrane. Bad way to die.
