You live, work or go to school near an anhydrous ammonia (NH 3 ) pipeline. You can recognize the location by marker signs. Anhydrous ammonia (NH 3 ) is used in manufacturing (refrigerants), agriculture (fertilizer), and household cleaning products. If accidentally released, NH 3 can burn mucous membranes in the eyes, mouth and respiratory system (breathing). Shelter in Place is one way to protect yourself.
