Anhydrous ammonia reacts with moisture in the mucous membranes to produce an alkaline solution (ammonium hydroxide).

Ammonia: toxicological overview Ref: PHE publications gateway number: 2014790 PDF , 256KB , 12 pages This file may not be suitable for users of assistive technology. [medical-dictionary.thefreedictionary.com] Symptoms of anhydrous ammonia exposure include eye, nose, and throat irritation; dyspnea; wheezing; chest pain; pulmonary edema; pink frothy sputum; skin burns; vesiculation; and frostbite. PURPOSE The purpose of this plan is to identify, and mitigate potential risks of anhydrous ammonia exposure that Facilities Management staff may encounter while performing their duties at the Ian Stewart Complex ice rink. Our eyes and lungs contain much more water than this rendering our vision (eyes) and breathing (respiratory system) especially at risk to the hazards of ammonia exposure. The accident in which these two women were injured involved a railroad … Main Routes of Exposure: Inhalation.
Eye contact. The first-response treatment for anhydrous ammonia exposure is to flush the exposed area (skin, nose, throat, eyes, and so on) with clean water for a minimum of 15 minutes. Anhydrous ammonia reacts with moisture in the mucous membranes to produce an alkaline solution (ammonium hydroxide). Signs and Symptoms of Acute Ammonia Exposure: Inhalation of ammonia may cause irritation and burns of the respiratory tract, laryngitis, dyspnea (shortness of breath), stridor (high-pitched respirations), and chest pain. A lifelong non-smoker who was the victim of a massive accidental exposure to anhydrous ammonia gas was followed up for 10 years. Anhydrous ammonia will extract water from body tissue. General Acute Exposure: Anhydrous ammonia reacts with moisture in mucosal surfaces (eyes, skin, and respiratory tract) to produce ammonium hydroxide, which may cause caustic injury. The extent of injury
One woman was found unconscious 90 min after the accident, and the other woman was exposed when she went outdoors for 30 min after the accident. After some improvement he was left with severe and fixed airways obstruction. Symptoms may include coughing, shortness of breath, difficult breathing and tightness in the chest.
As the exposure period increased, the LC50 decreased in value from 28130 mg Executive summary: The acute inhalation toxicity of ammonia was assessed by exposing groups of male and female Wistar rats were to atmospheric ammonia for 10, 20, 40 or 60 minutes. Ammonia (anhydrous or aqueous) or ammonium sulphate can be used for ammoniation and should be added after disinfection and partial dechlorination (if applicable). Exposure Routes.
