2,2-DICHLOROACETYL CHLORIDE ICSC: 0869 Dichloroacetyl chloride C2HCl3O / Cl2CHCOCl Molecular mass: 147.4 ICSC #    0869 CAS #     79-36-7 RTECS # AO6650000 UN #        1765 EC #         607-067-00-0 Types of Hazard/ Exposure Acute Hazards/ Symptoms Prevention First Aid/ Fire Fighting FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire. NO open flames. NO contact with water. Powder, carbon dioxide. NO water. Explosion Above 66°C explosive vapour/air mixtures may be formed. Above 66°C use a closed system, ventilation. In case of fire: cool drums, etc., by spraying with water but avoid contact of the substance with water. Exposure PREVENT GENERATION OF MISTS! AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!  •Inhalation Sore throat. Cough. Burning sensation. Shortness of breath. Laboured breathing. Symptoms may be delayed (see Notes). Ventilation, local exhaust, or breathing protection. Fresh air, rest. Half-upright position. Artificial respiration if indicated. Refer for medical attention.  •Skin Pain. Redness. Blisters. Skin burns. Protective gloves. Protective clothing. First rinse with plenty of water, then remove contaminated clothes and rinse again. Refer for medical attention.  •Eyes Pain. Redness. Severe deep burns. Loss of vision. 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. Abdominal cramps. Shock or collapse. Do not eat, drink, or smoke during work. Rinse mouth. Do NOT induce vomiting. Give nothing to drink. Refer for medical attention. Spillage Disposal Storage Packaging & Labelling Evacuate danger area! Consult an expert! Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. (Extra personal protection: complete protective clothing including self-contained breathing apparatus). Separated from strong oxidants, strong bases, food and feedstuffs , alcohols , water . Dry. Well closed. Keep in a well-ventilated room. Do not transport with food and feedstuffs.

Physical Dangers: Chemical Dangers: The substance decomposes on heating and on contact with moisture, metal powder, producing toxic fumes of hydrogen chloride, phosgene , causing fire and explosion hazard. Reacts with strong oxidants, alcohols, water. Attacks many metals forming flammable/explosive gas (hydrogen - see ICSC 0001). Occupational Exposure Limits: TLV not established. MAK not established. Routes of Exposure: The substance can be absorbed into the body by inhalation, 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: Tear drawing. The substance is corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion. Inhalation of the substance may cause lung oedema (see Notes). Exposure may result in death. Effects of Long-Term or Repeated Exposure: Physical Properties Boiling point: 107-108°C Relative density (water = 1): 1.5 Solubility in water: decomposes Vapour pressure, kPa at 20°C: 3.1 Relative vapour density (air = 1): 5.1 Flash point: 66°C Auto-ignition temperature: 585°C Explosive limits, vol% in air: 11.9-? Environmental Data This substance may be hazardous to the environment; special attention should be given to water. N O T E S Reacts violently with fire extinguishing agents such as water. 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.
