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 AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!  •INHALATION Avoid inhalation of fine dust and mist. Local exhaust or breathing protection. Fresh air, rest. Refer for medical attention.  •SKIN Protective gloves. Remove contaminated clothes. Rinse and then wash skin with water and soap.  •EYES Redness. Pain. Safety goggles. 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. Give plenty of water to drink. Refer for medical attention. 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: chemical protection suit including self-contained breathing apparatus). Provision to contain effluent from fire extinguishing. Separated from food and feedstuffs . Do not transport with food and feedstuffs.

International Chemical Safety Cards BENTAZONE ICSC: 0828 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS TO WHITE CRYSTALLINE POWDER. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating or on burning producing toxic fumes including sulfur oxides, nitrogen oxides. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation 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: The substance irritates the eyes. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Decomposes below boiling point at 200°C Melting point: 137-139°C Solubility in water: none Vapour pressure, Pa at 20°C: < 0.001 Octanol/water partition coefficient as log Pow: -0.46 ENVIRONMENTAL DATA Avoid release to the environment in circumstances different to normal use. N O T E S 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. Adagio, Basagran, Pledge are trade names.
