NO open flames, NO sparks, and NO smoking. See Chemical Dangers. Water in large amounts. Foam. Alcohol-resistant foam. Powder. Carbon dioxide. EXPLOSION Vapour/air mixtures are explosive. Risk of fire and explosion on mixing with alkalis, acids or strong oxidants. Closed system, ventilation, explosion-proof electrical equipment and lighting. Use reduced-sparking handtools. In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE STRICT HYGIENE! IN ALL CASES CONSULT A DOCTOR! INHALATION Corrosive. Burning sensation. Cough. Laboured breathing. Shortness of breath. Sore throat. Symptoms may be delayed (see Notes). Ventilation, local exhaust, or breathing protection. Fresh air, rest. Half-upright position. Refer for medical attention. SKIN Corrosive. Redness. Serious skin burns. Pain. Blisters. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention. EYES Corrosive. 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 Abdominal cramps. Burning sensation. Collapse. 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! Collect leaking liquid in covered containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT let this chemical enter the environment (extra personal protection: complete protective clothing including self-contained breathing apparatus). Fireproof. Separated from strong oxidants, strong bases, strong acids, food and feedstuffs. Cool. Store only if stabilized. Unbreakable packaging; put breakable packaging into closed unbreakable container. Do not transport with food and feedstuffs. F symbol T+ symbol R:11-25-26-34 S:3/9/14-26-36/37/39-38-45 UN Haz Class: 6.1 UN Subsidiary Risks: 3 UN Pack Group: I Marine pollutant.

International Chemical Safety Cards ACROLEIN ICSC: 0090 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: YELLOW TO COLOURLESS LIQUID , WITH PUNGENT ODOUR. PHYSICAL DANGERS: The vapour is heavier than air and may travel along the ground; distant ignition possible. CHEMICAL DANGERS: The substance can form explosive peroxides. The substance may polymerize with fire and explosion hazard. Upon heating, toxic fumes are formed. Reacts with alkalis, acids, amines, sulfur dioxide, thiourea, metal salts and oxidants causing fire and explosion hazard. OCCUPATIONAL EXPOSURE LIMITS: TLV: 0.1 ppm; 0.23 mg/m3 (ACGIH 1992-1993). TLV (as STEL): 0.3 ppm; 0.69 mg/m3 (ACGIH 1992-1993). PDK (as STEL): 0.2 mg/m3 (USSR 1993). OSHA PEL: TWA 0.1 ppm (0.25 mg/m3) NIOSH REL: TWA 0.1 ppm (0.25 mg/m3) ST 0.3 ppm (0.8 mg/m3) See Appendix C (Aldehydes) NIOSH IDLH: 2 ppm ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its vapour 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: Corrosive. Tear drawing. The substance is corrosive to the eyes, the skin and the respiratory tract. Inhalation of this substance may cause lung oedema (see Notes). Exposure at high levels may result in death. The effects may be delayed. Medical observation is indicated. PHYSICAL PROPERTIES Boiling point: 53°C Melting point: -88°C Relative density (water = 1): 0.8 Solubility in water, g/100 ml at 20°C: 20 Vapour pressure, kPa at 20°C: 29 Relative vapour density (air = 1): 1.9 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.2 Flash point: -26°C Auto-ignition temperature: 234°C Explosive limits, vol% in air: 2.8-31% Octanol/water partition coefficient as log Pow: 0.9 ENVIRONMENTAL DATA This substance may be hazardous to the environment; special attention should be given to fish. NOTES 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. An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert. The odour warning when the exposure limit value is exceeded is insufficient. Check for peroxides prior to distillation; render harmless if positive. Also consult publication Health and Safety Guide No.67 Acrolein, and Environmental Health Criteria No.127 Acrolein, of IPCS.
