Liquid formulations containing organic solvents may be flammable. NO open flames. Powder, water spray, foam, carbon dioxide. EXPLOSION Finely dispersed particles form explosive mixtures in air. Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting. EXPOSURE PREVENT DISPERSION OF DUST! STRICT HYGIENE!  •INHALATION Ventilation (not if powder), local exhaust, or breathing protection. Fresh air, rest. Refer for medical attention.  •SKIN Protective gloves. Protective clothing. Remove contaminated clothes. Rinse skin with plenty of water or shower.  •EYES Safety goggles, 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 Do not eat, drink, or smoke during work. Wash hands before eating. Rinse mouth. Rest. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Do NOT wash away into sewer. Vacuum spilled material. Carefully collect remainder, then remove to safe place. Provision to contain effluent from fire extinguishing. Separated from food and feedstuffs. Do not store near heat or open flame. Do not transport with food and feedstuffs.

International Chemical Safety Cards ALACHLOR ICSC: 0371 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: ODOURLESS, COLOURLESS TO CREAM-COLOURED, CRYSTALLINE SOLID. PHYSICAL DANGERS: Dust explosion possible if in powder or granular form, mixed with air. CHEMICAL DANGERS: On combustion, forms toxic gases (carbon monoxide, see ICSC 0023), nitrogen oxides, hydrogen chloride (see ICSC 0163). 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 and by ingestion. 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: EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the liver. This substance is possibly carcinogenic to humans. PHYSICAL PROPERTIES Melting point: 40°C Density: 1.1 g/cm3 Solubility in water, g/100 ml at 25°C: none >> Flash point: 137°C c.c. Octanol/water partition coefficient as log Pow: 3.5 ENVIRONMENTAL DATA The substance is toxic to aquatic organisms. Avoid release to the environment in circumstances different to normal use. N O T E S Carrier solvents used in commercial formulations may change physical and toxicological properties. ADDITIONAL INFORMATION ICSC: 0371 ALACHLOR (C) IPCS, CEC, 1994
