Inhalation and ocular exposure are mostlikely due to its gaseous nature.POTENTIAL HEALTH EFFECTSINHALATIONEYESSKININGESTIONInhalation may result in irritation of eyes and nose with sore throat, cough, chest tightness,headache, ataxia and confusion. Dyspnoea and stridor due to laryngeal oedema my follow.Ocular exposure contact may result in pain, blepharospasm, lacrimation, conjunctivitis,palpebral oedema, photophobia and corneal burns which should be considered anophthalmic emergency.Dermal exposure may result in deep, full thickness, liquefaction burns due to thesolubilisation of proteins and collagen, saponification of lipids and the dehydration of tissuecells leading to extensive damage.Ingestion may cause immediate burning of the mouth and throat, drooling, difficultyswallowing with retrosternal and abdominal pain. There is often hypersalivation andvomiting. Haematemesis and shock may complicate severe cases. The larynx may also beburned causing oedema, airway obstruction and difficulty clearing bronchial secretions.Strong alkalis such as ammonia may damage the oesophagus more than the stomach withulceration, perforation and mediastinitis.There is no evidence to suggest that ammonia can affect the health of the unborn child.ACUTE HEALTH HAZARDS: Ammonia gas and mists of solution are severe respiratory tract irritants.Concentrated solutions or vapours may cause severe, penetrating dermal burns or necrosis. Ammonia maycause eye irritation, lacrimation and conjunctivitis and has been reported to cause temporary or permanentblindness. Ingestion may cause epigastric pain, nausea and vomiting, swelling of the lips, mouth and larynx.ppm mg m -3 Signs and symptoms50 35 Slight irritation to eyes, nose and throat100 70 Rapid irritation to eye and respiratory tract700 488 Immediately irritating to eyes and throat1500 1045 Pulmonary oedema and coughing2500 1742 Life threateningCHRONIC HEALTH HAZARDS: Prolonged low concentrations of ammonia may lead to chronic bronchitis,pulmonary fibrosis and chemical pneumonitis.CARCINOGENICITY: Non Carcinogen.
