Gives off irritating or toxic fumes (or gases) in a fire. NO open flames. Powder, water spray, foam, carbon dioxide. EXPLOSION In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE AVOID ALL CONTACT!  •INHALATION Cough. Laboured breathing. Sore throat. Ventilation. Fresh air, rest. Half-upright position. Refer for medical attention.  •SKIN Redness. Pain. Protective gloves. Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.  •EYES Redness. Pain. Face shield . First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Burning sensation. (Further see Inhalation). 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 Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Personal protection: complete protective clothing including self-contained breathing apparatus. Separated from food and feedstuffs . See Chemical Dangers. Ventilation along the floor. Do not transport with food and feedstuffs.

International Chemical Safety Cards BENZAL CHLORIDE ICSC: 0101 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS LIQUID , WITH PUNGENT ODOUR. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on burning or on contact with acids and water producing toxic fumes including hydrogen chloride (see ICSC 0163). Reacts with strong oxidants . OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK: skin absorption (H); Carcinogen category: 2; (DFG 2004). ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. INHALATION RISK: A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: The substance is severely irritating to the eyes , the skin and the respiratory tract . EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: This substance is probably carcinogenic to humans. PHYSICAL PROPERTIES Boiling point: 205°C Melting point: -17°C Relative density (water = 1): 1.26 Solubility in water: none Vapour pressure, kPa at 35.4°C: 0.13 Flash point: 93°C c.c.
