Above 63°C use a closed system, ventilation. EXPOSURE  •INHALATION Cough. Sore throat. Ventilation, local exhaust, or breathing protection. Fresh air, rest.  •SKIN Redness. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse skin with plenty of water or shower.  •EYES Redness. Pain. Safety spectacles or face shield. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Sore throat. Do not eat, drink, or smoke during work. Rinse mouth. Rest. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Personal protection: filter respirator for organic gases and vapours. Collect leaking liquid in sealable containers.

International Chemical Safety Cards BENZALDEHYDE ICSC: 0102 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS TO YELLOW LIQUID , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance can form explosive peroxides under special conditions. Reacts violently with aluminium, bases, iron, oxidants and phenol causing fire and explosion hazard. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK: IIb (not established but data is available) (DFG 2005). ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its vapour, through the skin 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 substance is irritating to the eyes EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Boiling point: 179°C Melting point: -26°C Relative density (water = 1): 1.05 Solubility in water, g/100 ml: (poor) at 25°C Vapour pressure, Pa at 26°C: 133 Relative vapour density (air = 1): 3.7 Flash point: 63°C c.c. Auto-ignition temperature: 192°C Explosive limits, vol% in air: 1.4 Octanol/water partition coefficient as log Pow: 1.48 ENVIRONMENTAL DATA The substance is harmful to aquatic organisms. N O T E S Rinse contaminated clothes with plenty of water because of fire hazard. Check for peroxides prior to distillation; eliminate if found.
