International Chemical Safety Cards DIISOPROPANOLAMINE ICSC: 0493 DIISOPROPANOLAMINE 1,1'-Iminodi-2-propanol Bis(2-propanol) amine DIPA C6H15NO2 / (CH3CHOHCH2)2NH Molecular mass: 133.2 CAS # 110-97-4 RTECS # UB6600000 ICSC # 0493 EC # 603-083-00-7 TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Combustible. NO open flames. Powder, alcohol-resistant foam, water spray, carbon dioxide. EXPLOSION Finely dispersed particles form explosive mixtures in air. Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting. In case of fire: keep drums, etc., cool by spraying with water.   EXPOSURE PREVENT DISPERSION OF DUST! STRICT HYGIENE! INHALATION Sore throat. Cough. Burning sensation. Shortness of breath. Laboured breathing. Symptoms may be delayed (see Notes). Local exhaust or breathing protection. Fresh air, rest. Half-upright position. Artificial respiration if indicated. Refer for medical attention. SKIN Pain. Redness. Blisters. Skin burns. Protective gloves. First rinse with plenty of water, then remove contaminated clothes and rinse again. Refer for medical attention. EYES Pain. Redness. Severe deep burns. Safety goggles, or eye protection in combination with breathing protection if powder. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor. INGESTION Burning sensation. Abdominal cramps. Shock or collapse. Do not eat, drink, or smoke during work. Rinse mouth. Do NOT induce vomiting. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. 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 acids. Dry. Keep in the dark. Well closed.

International Chemical Safety Cards DIISOPROPANOLAMINE ICSC: 0493 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: WHITE HYGROSCOPIC CRYSTALLINE POWDER , WITH CHARACTERISTIC ODOUR. TURNS YELLOW ON EXPOSURE TO LIGHT AND AIR. PHYSICAL DANGERS: Dust explosion possible if in powder or granular form, mixed with air. CHEMICAL DANGERS: The substance decomposes on heating and on burning producing toxic gases (nitrogen oxides). The solution in water is a medium strong base and reacts with strong acids. Reacts violently with strong oxidants causing fire and explosion hazard. OCCUPATIONAL EXPOSURE LIMITS (OELs): TLV not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion. INHALATION RISK: No indication can be given about the rate in which a harmful concentration in the air is reached 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 the aerosol may cause lung oedema (see Notes). The effects may be delayed. Medical observation is indicated. PHYSICAL PROPERTIES Boiling point: 248°C Melting point: 42°C Relative density (water = 1): 0.99 Solubility in water, g/100 ml at 20°C: 87 Vapour pressure, Pa at 42°C: 2,67 Relative vapour density (air = 1): 4.6 Flash point: 127°C o.c. Auto-ignition temperature: 374°C Explosive limits, vol% in air: 1.1-5.4

ENVIRONMENTAL DATA
N O T E S
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. NFPA Code: H2; F1; RO;
