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 Risk of fire and explosion. EXPOSURE STRICT HYGIENE! AVOID EXPOSURE OF (PREGNANT) WOMEN! IN ALL CASES CONSULT A DOCTOR!  •INHALATION Blue skin. Convulsions. Headache. Sweating. Laboured breathing. Unconsciousness. Ventilation (not if powder), local exhaust, or breathing protection. Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.  •SKIN MAY BE ABSORBED! (Further see Inhalation). Protective gloves. Protective clothing. Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.  •EYES Redness. Pain. Blurred vision. Temporary loss of vision. Safety goggles, face shield, 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 Abdominal pain. Vomiting. (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. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Rest. 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: P3 filter respirator for toxic particles). Provision to contain effluent from fire extinguishing. Separated from food and feedstuffs. Ventilation along the floor. Do not transport with food and feedstuffs. Marine pollutant.

International Chemical Safety Cards DINOSEB ICSC: 0149 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: ORANGE CRYSTALS , WITH PUNGENT ODOUR. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating producing toxic fumes including nitrogen oxides. The solution in water is a weak acid. Attacks many metals in presence of water. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. PDK not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation, through the skin and by ingestion. INHALATION RISK: A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster. EFFECTS OF SHORT-TERM EXPOSURE: The substance irritates the eyes. The substance may cause effects on the gastrointestinal tract and central nervous system. Exposure to the aerosol in hot environment may result in death. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The substance may have effects on the kidneys, liver, blood, immune system and eyes , resulting in cataract. May cause reproductive toxicity in humans. PHYSICAL PROPERTIES Melting point: 38-42°C Relative density (water = 1): 1.3 at 30°C Solubility in water: none at 20°C (<0.1 g/100 ml) Vapour pressure, Pa at 20°C: 0.007 Relative vapour density (air = 1): 8.3 ENVIRONMENTAL DATA The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment; special attention should be given to honey bees, birds and mammals. The substance may cause long-term effects in the aquatic environment. N O T E S Temperature of decomposition unknown in literature. If the pesticide is present under the form of a formulation containing hydrocarbon solvents, vomiting may not be induced. Depending on the degree of exposure, periodic medical examination is indicated. Carrier solvents used in commercial formulations may change physical and toxicological properties. Do NOT take working clothes home.
