Potential health effects

Inhalation, Skin absorption, Skin contact, eye contact, ingestion Eye Contact Can cause permanent eye injury. Symptoms include stinging, tearing, redness, and swelling of eyes. Can injure the cornea and cause blindness. Additional symptoms of eye exposure may include: halo vision (blurred vision around bright objects). Skin Contact Can cause permanent skin damage. Symptoms may include redness, burning, and swelling of skin, burns, and other skin damages. Additional symptoms of skin contact may include: allergic skin reaction (delayed skin rash which may be followed by blistering, scaling and other skin effects). Persons exposed to this material may experience an allergic reaction when exposed to other amines. Passage of this material into the body through the skin is possible, and skin contact may be harmful. May be toxic is absorbed through the skin. Ingestion Swallowing this material may be harmful or fatal. Symptoms may include severe stomach and intestinal irritation) nausea, vomiting, diarrhea), abdominal pain, and vomiting of blood. Swallowing this material may cause burns and destroy tissue in the mouth, throat, and digestive tract. Low blood pressure and shock may occur as a result of severe tissue injury. May be toxic if ingested. Inhalation Breathing of vapor of mist is possible. Breathing this material may be harmful or fatal. Symptoms may include severe irritation and burns to the nose, throat, and respiratory tract. Symptoms are not expected at air concentrations below the recommended exposure limits, if applicable (see Section 8). May be toxic if inhaled.

Medical Conditions Generally Aggravated by Exposure

Preexisting disorders of the following organs (or organ systems) may be aggravated by exposure to this material: respiratory tract, skin, lung (for example, asthma-like conditions), liver, kidney, eye. Exposure to this material may aggravate any preexisting condition sensitive to a decrease in available oxygen, such as chronic lung disease, coronary artery disease or anemias. Symptoms Signs and symptoms of exposure to this material through breathing, swallowing, and/or passage of the material through the skin may include: stomach or intestinal upset (nausea, vomiting, diarrhea), irritation (nose, throat, airways), cough, headache, dizziness, shortness of breath, methemoglobinemia (blood abnormality which causes a blue coloring to the skin). Exposure to this product (or a component) may cause an allergic reaction (narrowing of the air passages of the lungs resulting in difficult breathing, tightness in the chest, coughing and wheezing) in some sensitive individuals. Other symptoms of an allergic reaction may include itchy and watery eyes, runny and stuffy nose, sweating, flushing, hives, rapid heart rate, and lowered blood pressure. May cause methemoglobinemia, a blood abnormality that may cause headache, difficulty breathing, lightheadedness, weakness, confusion, rapid heart rate and cyanosis (lack of oxygen in the tissues causing blue-colored skin and nails). Target Organs Overexposure to this material (or its components) has been suggested as a cause of the following effects in laboratory animals: eye damage, kidney damage, liver damage, lung damage Carcinogenicity There is no information available. The chance of this material causing cancer is unknown. This material is not listed as a carcinogen by the International Agency for Research on Cancer (IARC), the National Toxicology Program (NTP), or the Occupational Safety and Health Administration (OSHA). Reproductive Hazard (Ethylenediamine): This material (or a component) has been shown to cause harm to the fetus in laboratory animal studies. The relevance of these findings to humans is uncertain. Mutagenic Effect Catechol) Human HeLa cell; 100 umol/L; MUREAV 92,427,82 [Mutat Res]

Further information

Ethylenediamine): This product contains amines which may react with nitrites or other nitrosating agents to form nitrosamines. Certain nitrosamines have been shown to cause cancer in laboratory animals.
