ANHYDROUS AMMONIA SAFETY

 

Anhydrous ammonia is an important source of nitrogen fertilizer for crops.  Improper handling of anhydrous ammonia can have catastrophic results on both plants and farm workers.  Common injuries are severe burns to eyes, skin and the respiratory tract.

 

·       Personal protective equipment (PPE) should always be worn.  Standard PPE should be non-vented goggles, rubber gloves with thermal lining, face shield or an approved respirator.  Wear a long sleeve shirt or coveralls.  A lightweight rubber suit would be preferred.

·       Keep anhydrous ammonia tanks out of direct sunlight so the pressure relief valve does not have to vent.

·       Make sure anhydrous ammonia tanks are not filled above the recommended capacity.

·       Use care when handling the hose end valve so that it does not open accidentally.  Do not move hose by handling valve handle.

·       Be sure to bleed hose coupling before disconnecting.

·       Use care when cleaning plugged knives as anhydrous ammonia could be build-up behind the plug.

·       Use emergency water supply for at least 15 minutes if exposed to anhydrous ammonia and then seek emergency medical attention.
