AMMONIA (NH3)

What is AMMONIA?	Ammonia is an industrial chemical used in agriculture and 
			industry. It is a clear gas with a strong odor, which usually 
			provides an adequate warning of its presence. It dissolves easily 
			in water to form ammonium hydroxide. Breathing in large amounts 
			can be fatal.

Signs and Symptoms:	Ammonia is very irritating to the eyes, nose, throat and 
			lungs. It can cause a burning sensation in the eyes, swelling of 
			the throat and airways, coughing, and fluid accumulation in the 
			lungs. Patients may have difficulty breathing, possibly resulting 
			in respiratory distress or death.  High amounts may cause severe eye 
			injury and burns of the skin. Liquid ammonia can cause frostbite. 
			Swallowing ammonia can burn the mouth, throat and stomach. 	

Exposure: 		Inhalation, ingestion, skin or eye exposure.		

What can you do?	Emergency response leaders may direct people to evacuate or 
			"shelter in place." 

Treatment:		There is no antidote. Remove contaminated clothing immediately 
			and wash exposed skin/eyes. Supportive hospital care is often necessary.  

Diagnosis:		Based on known or suspected exposure.
