International Chemical Safety Cards ETHYL ACETOACETATE ICSC: 1024 ETHYL ACETOACETATE Acetoacetic acid ethyl ester Ethyl acetylacetate 3-Oxobutanoic acid ethyl ester C6H10O3/CH3COCH2COOC2H5 Molecular mass: 130.14 CAS # 141-97-9 RTECS # AK5250000 ICSC # 1024 TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire. NO open flames. NO contact with strong oxidants. Powder, alcohol-resistant foam, water spray, carbon dioxide. EXPLOSION Above 84°C explosive vapour/air mixtures may be formed. Above 84°C use a closed system, ventilation.   EXPOSURE PREVENT GENERATION OF MISTS! INHALATION Burning sensation. Cough. Sore throat. Ventilation. Avoid inhalation of fine dust and mist. Fresh air, rest. SKIN Redness. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention. EYES Redness. Safety goggles 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 Do not eat, drink, or smoke during work. Wash hands before eating. Rinse mouth. Give plenty of water to drink. Rest. 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. Wash away remainder with plenty of water. Separated from strong oxidants. Ventilation along the floor.
