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.
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.
