International Chemical Safety Cards BUTYL FORMATE ICSC: 0402 Formic acid, butyl ester n-Butyl formate C5H10O2 / HCOO(CH2)3CH3 Molecular mass: 102.1 ICSC #    0402 CAS #     592-84-7 RTECS # LQ5500000 UN #        1128 EC #         607-017-00-8 May 05, 2010 Validated Fa, rack: 10-2004, Sankt Augustin; TEC (R), EU classification updated TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Highly flammable. NO open flames, NO sparks, and NO smoking. Powder, alcohol-resistant foam, water spray, carbon dioxide EXPLOSION Vapour/air mixtures are explosive. Heating will cause rise in pressure with risk of bursting. Risk of fire and explosion on contact with strong oxidants. Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling. Prevent build-up of electrostatic charges (e.g., by grounding). In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE  •INHALATION Cough. Shortness of breath. Headache. Drowsiness. Ventilation, local exhaust, or breathing protection. Fresh air, rest. Refer for medical attention.  •SKIN Redness. Protective gloves. Remove contaminated clothes. Rinse and then wash skin with water and soap.  •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 Sore throat. (Further see Inhalation). Do not eat, drink, or smoke during work. Rinse mouth. Do NOT induce vomiting. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Evacuate danger area! Consult an expert! Ventilation. Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. 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. Fireproof. Separated from strong oxidants. Note: C F symbol Xi symbol R: 11-36/37 S: 2-9-16-24-33 UN Hazard Class: 3 UN Packing Group: II Signal: Danger Flame-Excl mark Highly flammable liquid and vapour May be harmful if swallowed Causes eye irritation May cause respiratory irritation SEE IMPORTANT INFORMATION ON BACK ICSC: 0402 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994. No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and NIOSH IDLH values.

International Chemical Safety Cards BUTYL FORMATE ICSC: 0402 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: The vapour mixes well with air, explosive mixtures are easily formed. As a result of flow, agitation, etc., electrostatic charges can be generated. CHEMICAL DANGERS: Reacts violently with strong oxidants causing fire and explosion hazard. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation 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 vapour is irritating to the eyes and the respiratory tract . The substance may cause effects on the central nervous system. Exposure far above the OEL could cause lowering of consciousness. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The liquid defats the skin.
