NO open flames. Foam. Dry powder. Carbon dioxide. EXPLOSION Above 86°C explosive vapour/air mixtures may be formed. Above 86°C use a closed system, ventilation. EXPOSURE  •INHALATION Ventilation. Fresh air, rest.  •SKIN Protective gloves. Remove contaminated clothes. Rinse skin with plenty of water or shower.  •EYES Safety spectacles Rinse with plenty of water (remove contact lenses if easily possible).  •INGESTION See EFFECTS OF SHORT-TERM EXPOSURE. Do not eat, drink, or smoke during work. Rinse mouth. Do NOT induce vomiting. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Personal protection: A filter respirator for organic gases and vapours. Remove all ignition sources. Ventilation. Collect leaking liquid in covered containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Separated from strong oxidants. Ventilation along the floor. Signal: Warning Health haz Combustible liquid May be harmful if swallowed and enters airways SEE IMPORTANT INFORMATION ON BACK ICSC: 0943 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 PROPYLENE GLYCOL DIACETATE ICSC: 0943 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS LIQUID PHYSICAL DANGERS: The gas mixes well with air, explosive mixtures are formed easily. CHEMICAL DANGERS: The substance can presumably form explosive peroxides. Reacts violently with oxidants OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body 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: If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Boiling point: 190°C Melting point: - 31°C Relative density (water = 1): 1,06 Solubility in water, g/100 ml: 10 (good) Vapour pressure, Pa at 20°C: 30 Relative vapour density (air = 1): 1.0 Flash point: 86°C Auto-ignition temperature: 431°C Explosive limits, vol% in air: 2.8 - 12.7 Octanol/water partition coefficient as log Pow: 0.8 Viscosity, mm2/s at 20 °C: 2.86 ENVIRONMENTAL DATA N O T E S Check for peroxides prior to distillation; eliminate if found. Health effects of exposure to the substance have not been investigated. ADDITIONAL INFORMATION ICSC: 0943 PROPYLENE GLYCOL DIACETATE (C) IPCS, CEC, 1994
