Gives off irritating or toxic fumes (or gases) in a fire. Powder, water spray, foam, carbon dioxide. EXPLOSION Risk of fire and explosion if formulations contain flammable/explosive solvents. EXPOSURE PREVENT DISPERSION OF DUST! AVOID ALL CONTACT! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!  •INHALATION Burning sensation. Local exhaust or breathing protection. Fresh air, rest.  •SKIN Redness. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.  •EYES Redness. Pain. Blurred vision. Safety spectacles, or eye protection in combination with breathing protection if powder. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Abdominal pain. Burning sensation. Do not eat, drink, or smoke during work. Wash hands before eating. Rinse mouth. Refer for medical attention. See Notes. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Do NOT wash away into sewer. Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. (Extra personal protection: P2 filter respirator for harmful particles). Provision to contain effluent from fire extinguishing. Separated from food and feedstuffs. Do not transport with food and feedstuffs. Marine pollutant.

International Chemical Safety Cards CHLOROTHALONIL ICSC: 0134 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: ODOURLESS COLOURLESS CRYSTALS. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating and on burning producing toxic and corrosive fumes including hydrogen chloride (see ICSC 0163) and nitrogen oxides. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation. INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered. EFFECTS OF SHORT-TERM EXPOSURE: The substance irritates the eyes, the skin and the respiratory tract. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the kidneys and gastrointestinal tract. PHYSICAL PROPERTIES Boiling point: 350°C Melting point: 250-251°C Relative density (water = 1): 1.8 Solubility in water, g/100 ml at 25°C: none (<0.01) Vapour pressure, Pa at 40°C: <1.3 Octanol/water partition coefficient as log Pow: 4.38 ENVIRONMENTAL DATA This substance may be hazardous to the environment; special attention should be given to water organisms. The substance may cause long-term effects in the aquatic environment. N O T E S If the pesticide is present under the form of a formulation containing hydrocarbon solvents, vomiting may not be induced! Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken. Carrier solvents used in commercial formulations may change physical and toxicological properties. If the pesticide is formulated in an organic solvent, also consult the ICSC of the solvent used. Bombardier, Bravo, Bravocarb, Chlorothalonil, Chlortocaffaro, Contact 75, Corbel, Daconil, Dacosoil, Exotherm, Faber, Forturf, Nopcocide, Sweep and Termil TPN are trade names.
