Ammonia

SECTION 2: Hazards identification

Emergency Overview DANGER! Toxic, flammable, corrosive, high-pressure gas. Harmful or fatal if inhaled. Can form explosive mixture with air. Causes eye, skin, and respiratory tract burns. Self-contained breathing apparatus may be required by rescue workers.

Principle Routes of Exposure

Absorbed through skin. Eye contact. Inhalation. Ingestion. EFFECTS OF A SINGLE (ACUTE) OVEREXPOSURE: INHALATION: Overexposure to concentrations moderately above the threshold Limit Value (TLV) of 25 ppm for ammonia may cause irritation of the eyes, nose, and throat. Higher concentrations may cause breathing difficulty, chest pain, bronchospasm, pink frothy sputum, and pulmonary edema. Overexposure may predispose to the development of acute bronchitis and pneumonia. SKIN CONTACT: Exposure to gas at high concentrations may cause chemical burns. SKIN Prolonged or widespread skin contact with the liquid may result in the absorption of harmful ABSORPTION: amounts of material. SWALLOWING: An unlikely route of exposure. This product is a gas at normal temperature and pressure, but may cause chemical burns of the mouth, throat, esophagus and stomach. EYE CONTACT: Exposure to gas may cause pain and excessive tearing, with acute corneal injury at high concentrations. EFFECTS OF REPEATED (CHRONIC) OVEREXPOSURE: Chronic exposure may cause chemical pneumonitis and kidney damage. OTHER EFFECTS OF OVEREXPOSURE: None currently known.

Medical Conditions Generally Aggravated by Exposure

OVEREXPOSURE Inhalation may aggravate asthma and inflammatory or fibrotic pulmonary disease. The skin irrtating properties of the material may aggravate. SIGNIFICANT LABORATORY DATA WITH POSSIBLE RELEVANCE TO HUMAN HEALTH HAZARD EVALUATION: None currently known.
