Gives off irritating or toxic fumes (or gases) in a fire. 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!  •INHALATION Local exhaust or breathing protection. Fresh air, rest.  •SKIN Protective gloves. Remove contaminated clothes. Rinse and then wash skin with water and soap.  •EYES Safety spectacles, 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 Do not eat, drink, or smoke during work. Wash hands before eating. Rinse mouth. Give plenty of water to drink. Rest. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Chemical protection suit including self-contained breathing apparatus. Separated from food and feedstuffs. Well closed. Do not transport with food and feedstuffs.

International Chemical Safety Cards SIMAZINE ICSC: 0699 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: WHITE CRYSTALLINE POWDER PHYSICAL DANGERS: Dust explosion possible if in powder or granular form, mixed with air. CHEMICAL DANGERS: Upon heating, toxic fumes are formed. OCCUPATIONAL EXPOSURE LIMITS: TLV 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 with skin may cause dermatitis. PHYSICAL PROPERTIES Melting point (decomposes): 225-227°C Density: 1.3 g/cm3 Solubility in water: none Vapour pressure, Pa at 20°C: 8.1 x 10 exp-7 Octanol/water partition coefficient as log Pow: 2.1 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 The substance is combustible but no flash point is available in literature. If the substance is formulated with solvent(s) also consult the card(s) (ICSC) of the solvent(s). Carrier solvents used in commercial formulations may change physical and toxicological properties.
