NO open flames, NO sparks, and NO smoking. See Chemical Dangers. Alcohol-resistant foam. Powder. Carbon dioxide. EXPLOSION Vapour/air mixtures are explosive. Risk of fire and explosion on contact with base(s), acid(s) or strong oxidants. Closed system, ventilation, explosion-proof electrical equipment and lighting. Use non-sparking handtools. In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position. EXPOSURE STRICT HYGIENE! IN ALL CASES CONSULT A DOCTOR!  •INHALATION Burning sensation. Cough. Laboured breathing. Shortness of breath. Sore throat. Nausea. Symptoms may be delayed (see Notes). Ventilation, local exhaust, or breathing protection. Fresh air, rest. Half-upright position. Refer for medical attention.  •SKIN Redness. Pain. Blisters. Skin burns. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse skin with plenty of water or shower. 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 in the throat and chest. Convulsions. Nausea. Do not eat, drink, or smoke during work. Wash hands before eating. Rinse mouth. Do NOT induce vomiting. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Evacuate danger area! Remove all ignition sources. Consult an expert! Collect leaking liquid in covered containers.

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 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 or explosion hazard. Upon heating, toxic fumes are formed. Reacts with strong acids , strong bases and strong oxidants , causing fire and explosion hazard. OCCUPATIONAL EXPOSURE LIMITS: TLV: 0.1 ppm (Ceiling value); (skin); A4; (ACGIH 2004). MAK: Carcinogen category: 3B; (DFG 2004). 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, through the skin 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: Tear drawing. The substance is severely irritating to the eyes the skin and the respiratory tract . Inhalation of this substance at high levels 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: 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 c.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 The substance is very toxic 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 are therefore essential. Immediate administration of an appropriate inhalation therapy 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. The occupational exposure limit value should not be exceeded during any part of the working exposure. Check for peroxides prior to distillation; render harmless if positive. Card has been partly updated in October 2004 and April 2005. See section Occupational Exposure Limits, Emergency response.
