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 52°C explosive vapour/air mixtures may be formed. Above 52°C closed system, ventilation. In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE  •INHALATION Cough. Nausea. Sore throat. Vomiting. Dizziness. Ventilation, local exhaust, or breathing protection. Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.  •SKIN MAY BE ABSORBED! Redness. 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, or eye protection in combination with breathing protection. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Abdominal pain. Diarrhoea. Do not eat, drink, or smoke during work. Rinse mouth. Give plenty of water to drink. Do NOT induce vomiting. Refer for medical attention. 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: filter respirator for organic gases and vapours.) Fireproof. Separated from strong oxidants, strong acids . Cool. Dry.

International Chemical Safety Cards 2-DIETHYLAMINOETHANOL ICSC: 0257 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS HYGROSCOPIC LIQUID , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: CHEMICAL DANGERS: On combustion, forms toxic gases (nitrogen oxides). Reacts with strong acids and strong oxidants . OCCUPATIONAL EXPOSURE LIMITS: TLV: as TWA 2 ppm (skin) (ACGIH 2001). MAK: 5 ppm; 24 mg/m3; H (2001). OSHA PEL: TWA 10 ppm (50 mg/m3) skin NIOSH REL: TWA 10 ppm (50 mg/m3) skin NIOSH IDLH: 100 ppm 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 very quickly on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: The substance is corrosive to the eyes and is severely irritating to the skin and the respiratory tract . The substance may cause effects on the nervous system . EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Boiling point: 163°C Melting point: -70°C Relative density (water = 1): 0.88 Solubility in water: miscible Vapour pressure, kPa at 20°C: 2.8 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.01 Flash point: 52°C (c.c.)
