NO open flames, NO sparks, and NO smoking. Dry powder, foam, carbon dioxide. EXPLOSION Vapour/air mixtures are explosive. Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling. In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE  •INHALATION Drowsiness. Dizziness. Ventilation, local exhaust, or breathing protection. Fresh air, rest.  •SKIN Dry skin. Protective gloves. Remove contaminated clothes. Rinse and then wash skin with water and soap.  •EYES Safety spectacles. 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. Rinse mouth. Do NOT induce vomiting. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Ventilation. Remove all ignition sources. Collect leaking liquid in covered containers. Absorb remaining liquid in dry sand or inert absorbent and remove to safe place. Do NOT wash away into sewer. Do NOT let this chemical enter the environment. Personal protection: filter respirator for organic gases and vapours. Fireproof. Separated from strong oxidants. Keep in the dark. Cool. Store in an area without drain or sewer access. R: S: UN Hazard Class: 3 UN Packing Group: II SEE IMPORTANT INFORMATION ON BACK ICSC: 0934 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 1-OCTENE ICSC: 0934 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 formed easily. As a result of flow, agitation, etc., electrostatic charges can be generated. CHEMICAL DANGERS: The substance can presumably form explosive peroxides. Reacts with strong oxidants. Attacks rubber, paints and lining materials. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its vapour. INHALATION RISK: A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis. Exposure at high levels could cause lowering of consciousness. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The liquid defats the skin. PHYSICAL PROPERTIES Boiling point: 123°C Melting point: -102°C Relative density (water = 1): 0.7 Solubility in water, g/100 ml at 25°C: 0.0004 Vapour pressure, kPa at 20°C: 2 Relative vapour density (air = 1): 3.9 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.06 Flash point: 10°C c.c. Auto-ignition temperature: 256 °C Explosive limits, vol% in air: 0.7-3.9 Octanol/water partition coefficient as log Pow: 3.5-4.6 ENVIRONMENTAL DATA The substance is toxic to aquatic organisms. Bioaccumulation of this chemical may occur in aquatic organisms. N O T E S Check for peroxides prior to distillation; eliminate if found.
