Gives off irritating or toxic fumes (or gases) in a fire. NO open flames. Water spray, foam, powder, 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! AVOID ALL CONTACT! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!  •INHALATION Cough. Sore throat. Abdominal pain. Nausea. Vomiting. Local exhaust or breathing protection. Fresh air, rest. Refer for medical attention.  •SKIN Redness. Pain. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse and then wash skin with water and soap.  •EYES Redness. Pain. 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 Abdominal pain. Nausea. Vomiting. Do not eat, drink, or smoke during work. Wash hands before eating. Rinse mouth. Give a slurry of activated charcoal in water to drink. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Personal protection: P3 filter respirator for toxic particles. Do NOT let this chemical enter the environment. Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Store in an area without drain or sewer access. Separated from acids, food and feedstuffs . Keep in a well-ventilated room. Well closed. Do not transport with food and feedstuffs. Marine pollutant.

International Chemical Safety Cards ZIRAM ICSC: 0348 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: WHITE POWDER PHYSICAL DANGERS: Dust explosion possible if in powder or granular form, mixed with air. CHEMICAL DANGERS: The substance decomposes on heating and on burning producing toxic and irritating fumes including nitrogen oxides and sulfur oxides . The substance decomposes on contact with acids . 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: A harmful concentration of airborne particles can be reached quickly when dispersed. EFFECTS OF SHORT-TERM EXPOSURE: The substance is severely irritating to the eyes , is irritating to the skin and the respiratory tract . EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact may cause skin sensitization. Tumours have been detected in experimental animals but may not be relevant to humans. PHYSICAL PROPERTIES Melting point: 240-250°C Density: 1.7 g/cm³ Solubility in water: very poor Octanol/water partition coefficient as log Pow: 1.09 ENVIRONMENTAL DATA The substance is very toxic to aquatic organisms. 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 If the substance is formulated with solvents also consult the ICSCs of these materials. Carrier solvents used in commercial formulations may change physical and toxicological properties.
