Pure ammonia -- usually called anhydrous ammonia (AA) -- is rich in nitrogen and is used as a fertilizer. AA is stored as a liquid under pressure in tanks and injected directly into the soil. AA is extremely dangerous. The liquid turns into a gas quickly producing subfreezing temperatures. It can also cause very severe burns. It is especially dangerous to the eyes. This video covers all aspects of the hazards and safe handling of anhydrous ammonia. Safety procedures that should be followed every time AA is used are carefully outlined.
