International Chemical Safety Cards ETHYLENEDIAMINE ICSC: 0269 ETHYLENEDIAMINE 1,2-Diaminoethane 1,2-Ethanediamine H2NCH2CH2NH2 Molecular mass: 60.1 CAS # 107-15-3 RTECS # KH8575000 ICSC # 0269 UN # 1604 EC # 612-006-00-6 TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Flammable. Gives off irritating or toxic fumes (or gases) in a fire. NO open flames, NO sparks, and NO smoking. Powder, alcohol-resistant foam, water spray, carbon dioxide. EXPLOSION Above 34°C explosive vapour/air mixtures may be formed. Above 34°C closed system, ventilation, and explosion-proof electrical equipment. In case of fire: keep drums, etc., cool by spraying with water.   EXPOSURE STRICT HYGIENE! INHALATION Burning sensation. Cough. Laboured breathing. Shortness of breath. Sore throat. Ventilation, local exhaust, or breathing protection. Fresh air, rest. Artificial respiration if indicated. Refer for medical attention. SKIN MAY BE ABSORBED! Redness. Skin burns. Pain. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention. EYES Redness. Pain. Blurred vision. Face shield. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor. INGESTION Abdominal pain. Diarrhoea. Sore throat. Vomiting. Do not eat, drink, or smoke during work. Rinse mouth. Give plenty of water to drink. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place (extra personal protection: complete protective clothing including self-contained breathing apparatus). Fireproof. Separated from incompatible materials (see Chemical Dangers). Dry.

International Chemical Safety Cards ETHYLENEDIAMINE ICSC: 0269 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS TO YELLOW HYGROSCOPIC LIQUID , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating producing toxic fumes (nitrogen oxides). The substance is a medium strong base. Reacts violently with chlorinated organic compounds strong oxidants. OCCUPATIONAL EXPOSURE LIMITS (OELs): TLV (as TWA): 10 ppm; 25 mg/m3 (ACGIH 1992-1993). MAK: 10 ppm; 25 mg/m3; (1992). ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation, through the skin and by ingestion. INHALATION RISK: A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: The substance is corrosive to the eyes, the skin and the respiratory tract. Inhalation of vapour or fumes may cause lung oedema (see Notes). EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation exposure may cause asthma. PHYSICAL PROPERTIES Boiling point: 116°C Melting point: 8.5°C Relative density (water = 1): 0.90 Solubility in water: miscible Vapour pressure, kPa at 20°C: 1.2 Relative vapour density (air = 1): 2.1 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.02 Flash point: 34°C (c.c.) Auto-ignition temperature: 385°C Explosive limits, vol% in air: 2.7-16.6 Octanol/water partition coefficient as log Pow: -1.2

ENVIRONMENTAL DATA	This substance may be hazardous to the environment; special attention should be given to water organisms.
NOTES
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered. The symptoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Anyone who has shown symptoms of asthma due to this substance should never again come into contact with this substance. Do NOT take working clothes home.
