Gives off irritating or toxic fumes (or gases) in a fire. In case of fire in the surroundings: use appropriate extinguishing media. EXPLOSION EXPOSURE  •INHALATION Convulsions. Tremor. 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 Safety goggles 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 (See Inhalation). Do not eat, drink, or smoke during work. Wash hands before eating. Give a slurry of activated charcoal in water to drink. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into containers. Do NOT let this chemical enter the environment. Personal protection: P3 filter respirator for toxic particles. Separated from food and feedstuffs. Do not transport with food and feedstuffs.

International Chemical Safety Cards FIPRONIL ICSC: 1503 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: WHITE POWDER . PHYSICAL DANGERS: CHEMICAL DANGERS: OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK 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 when dispersed. EFFECTS OF SHORT-TERM EXPOSURE: The substance may cause effects on the central nervous system , resulting in irritability and convulsions . The effects may be delayed. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The substance may have effects on the liver , resulting in tissue lesions . PHYSICAL PROPERTIES Melting point: 201°C Solubility in water: very poor Vapour pressure, Pa at 20°C: negligible Octanol/water partition coefficient as log Pow: 4 ENVIRONMENTAL DATA The substance is very toxic to aquatic organisms. This substance may be hazardous in the environment; special attention should be given to birds and honey bees. This substance does enter the environment under normal use. Great care, however, should be given to avoid any additional release, e.g. through inappropriate disposal. N O T E S Carrier solvents used in commercial formulations may change physical and toxicological properties. If the substance is formulated with solvents also consult the ICSCs of these materials.
