Never leave the equipment during transfer. After filling the applicator tank, close all valves on the nurse tank, secure the liquid fill hose, and replace all protective dust covers. Handle the hose by the valve body, not the hand wheel. Close hand wheel valves by hand. Do not use a wrench, as the stem or valve seat may be damaged, allowing the ammonia to escape.
Immediate action is important when anhydrous ammonia is involved in an accident.
Water is the best and only emergency first aid treatment for ammonia burns. Flush or irrigate the injured area with lots of water for at least 15 minutes before going for professional medical help. Eyes doused with ammonia will close involuntarily. They must be forced open so that the water can flush the entire eye surface and inner lining of the eyelids. If you are wearing contact lenses while working with ammonia, be sure to remove them immediately before you begin the flushing process.
