NO open flames. Powder, alcohol-resistant foam, water spray, carbon dioxide. EXPLOSION EXPOSURE PREVENT GENERATION OF MISTS!  •INHALATION Cough. Dizziness. Headache. Ventilation. Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.  •SKIN Dry skin. Protective gloves. Remove contaminated clothes. Rinse skin with plenty of water or shower.  •EYES Redness. Pain. Safety goggles. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Abdominal pain. Dullness. Nausea. Unconsciousness. Vomiting. Do not eat, drink, or smoke during work. Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention. If no medical personnel are available and the patient is conscious, ingestion of alcoholic beverage may prevent kidney failure. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Collect leaking and spilled liquid in sealable containers as far as possible. Wash away remainder with plenty of water. (Extra personal protection: A/P2 filter respirator for organic vapour and harmful dust). Separated from strong oxidants, strong bases. Dry. Ventilation along the floor.

International Chemical Safety Cards ETHYLENE GLYCOL ICSC: 0270 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: ODOURLESS , COLOURLESS, VISCOUS, HYDROSCOPIC LIQUID PHYSICAL DANGERS: CHEMICAL DANGERS: On combustion, forms toxic gases. Reacts with strong oxidants and strong bases. OCCUPATIONAL EXPOSURE LIMITS: TLV (as STEL): 100 mg/m3 (ceiling values) (ACGIH 1998). OSHA PEL: none NIOSH REL: See Appendix D NIOSH IDLH: No data ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation and through the skin. INHALATION RISK: A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: The substance irritates the eyes and the respiratory tract. The substance may cause effects on the the kidneys and central nervous system , resulting in renal failure and brain injury. Exposure could cause lowering of consciousness. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The substance may have effects on the central nervous system , resulting in abnormal eye movements (nystagmus). PHYSICAL PROPERTIES Boiling point: 198°C Melting point: -13°C Relative density (water = 1): 1.1 Solubility in water: miscible Vapour pressure, Pa at 20°C: 7 Relative vapour density (air = 1): 2.1 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.00 Flash point: 111°C (c.c.) Auto-ignition temperature: 398°C Explosive limits, vol% in air: 3.2-15.3 Octanol/water partition coefficient as log Pow: -1.93 ENVIRONMENTAL DATA N O T E S The occupational exposure limit value should not be exceeded during any part of the working exposure.
