Gives off irritating or toxic fumes (or gases) in a fire. NO open flames, NO sparks, and NO smoking. NO contact with oxidants. Powder, alcohol-resistant foam, water spray, carbon dioxide. EXPLOSION Above 29°C explosive vapour/air mixtures may be formed. Above 29°C use a closed system, ventilation, and explosion-proof electrical equipment. In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE PREVENT GENERATION OF MISTS! AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!  •INHALATION Burning sensation. Cough. Sore throat. Laboured breathing. Shortness of breath. Symptoms may be delayed (see Notes). Ventilation, local exhaust, or breathing protection. Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.  •SKIN Redness. Pain. Skin burns. Protective gloves. Protective clothing. First rinse with plenty of water, then remove contaminated clothes and rinse again. Refer for medical attention.  •EYES Redness. Pain. Severe deep burns. 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 Burning sensation. Abdominal pain. Shock or collapse. 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 Remove all ignition sources. 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. Wash away remainder with plenty of water. Do NOT wash away into sewer. Do NOT let this chemical enter the environment. (Extra personal protection: complete protective clothing including self-contained breathing apparatus.) Fireproof. Separated from food and feedstuffs, strong oxidants, strong acids. Do not transport with food and feedstuffs. Unbreakable packaging; put breakable packaging into closed unbreakable container.

International Chemical Safety Cards DIISOBUTYLAMINE ICSC: 1442 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on burning producing toxic fumes including nitrogen oxides . The substance is a medium strong base. Reacts with acids and oxidants causing fire and explosion hazard. Attacks copper and zinc and their alloys, aluminum and galvanized steel. Solutions in water slowly etch glass. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation, 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. Corrosive on ingestion. Inhalation may cause lung oedema (see Notes). The effects may be delayed. Medical observation is indicated. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Boiling point: 140°C Melting point: -74°C Relative density (water = 1): 0.75 Solubility in water, g/100 ml at 25°C: 0.22 Vapour pressure, kPa at 25°C: 0.97 Relative vapour density (air = 1): 4.5 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.03 Flash point: 29°C c.c. Octanol/water partition coefficient as log Pow: 2.84/3.04 ENVIRONMENTAL DATA The substance is harmful to aquatic organisms. 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 is therefore essential. Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
