Gives off irritating or toxic fumes (or gases) in a fire. NO open flames. Dry powder, carbon dioxide, water spray, foam. EXPLOSION EXPOSURE PREVENT DISPERSION OF DUST!  •INHALATION Cough. Local exhaust or breathing protection. Fresh air, rest.  •SKIN Protective gloves. Protective clothing. Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.  •EYES Redness. 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. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Personal protection: particulate filter adapted to the airborne concentration of the substance. Sweep spilled substance into plastic containers. Moisten the remainder. Do NOT let this chemical enter the environment. Provision to contain effluent from fire extinguishing.

International Chemical Safety Cards 2-CHLORO-6-TRICHLOROMETHYLPYRIDINE ICSC: 1658 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS TO WHITE CRYSTALS , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating producing toxic fumes OCCUPATIONAL EXPOSURE LIMITS: TLV: 10 mg/m³ as TWA, 20 mg/m³ as STEL; A4 (not classifiable as a human carcinogen); (ACGIH 2008). MAK not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body in hazardous amounts through the skin and by ingestion. The substance can be absorbed into the body by inhalation. 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: See Notes. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Boiling point at 1.5kPa: 136°C Melting point: 63°C Solubility in water: none Vapour pressure, Pa at 23°C: 0.4 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.0 Flash point: 100°C c.c. Octanol/water partition coefficient as log Pow: 3.4 ENVIRONMENTAL DATA The substance is toxic to aquatic organisms. This substance does enter the environment under normal use. Great care, however, should be given to avoid any additional release, e.g. through inappropriate disposal. N O T E S Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken. N-Serve, Dowco-163 are trade names. Transport Emergency Card: TEC (R)-90GM7-III Card has been partially updated in February 2009: see Occupational Exposure Limits.
