Liquid formulations containing organic solvents may be flammable. 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 PREVENT DISPERSION OF DUST!  •INHALATION Confusion. Convulsions. Cough. Dizziness. Headache. Nausea. Vomiting. Weakness. Disorientation. Local exhaust or breathing protection. Fresh air, rest. Refer for medical attention.  •SKIN Redness. Protective gloves. Remove contaminated clothes. Rinse and then wash skin with water and soap.  •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 Abdominal pain. Diarrhoea. (Further see Inhalation). Do not eat, drink, or smoke during work. Wash hands before eating. Rinse mouth. Give a slurry of activated charcoal in water to drink. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into covered containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Do NOT let this chemical enter the environment. (Extra personal protection: complete protective clothing including self-contained breathing apparatus.) Separated from acids. Keep in a well-ventilated room.

International Chemical Safety Cards DICOFOL ICSC: 0752 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS CRYSTALS. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on burning or on contact with acids , acid fumes or bases producing toxic and corrosive fumes including hydrogen chloride . OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion. INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered. EFFECTS OF SHORT-TERM EXPOSURE: The substance is irritating to the eyes and the skin (technical grade). The substance may cause effects on the central nervous system , liver and kidneys . EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact with skin may cause dermatitis. PHYSICAL PROPERTIES Melting point: 77-78°C Density: 1.13 g/cm3 Solubility in water: none Flash point: 193°C o.c. Octanol/water partition coefficient as log Pow: 4.28 ENVIRONMENTAL DATA The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur in fish. N O T E S The appearance and physical properties of technical products can differ from those of the pure substance. Carrier solvents used in commercial formulations may change physical and toxicological properties. Acarin, Carbax, Kelthane and Mitigan are trade names.
