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  •INHALATION Local exhaust or breathing protection. Fresh air, rest.  •SKIN Protective gloves. Rinse and then wash skin with water and soap.  •EYES 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. Rinse mouth. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting.

International Chemical Safety Cards STARCH ICSC: 1553 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: OCCUPATIONAL EXPOSURE LIMITS: TLV: 10 mg/m³ as TWA; A4; (ACGIH 2004). MAK not established. ROUTES OF EXPOSURE: INHALATION RISK: A nuisance-causing concentration of airborne particles can be reached quickly when dispersed. EFFECTS OF SHORT-TERM EXPOSURE: EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact with skin may cause dermatitis. PHYSICAL PROPERTIES Decomposes below melting point Density: 1.5 g/cm3 Solubility in water: none Auto-ignition temperature: 410 °C ENVIRONMENTAL DATA N O T E S Starch is found in many plants, including maize (corn), tapioca, wheat, rice, barley, oats, millet, lentils, potatoes, amd other grains. Most starches are composed of 22% to 26% amylose and 74 to 78% amylopectin. ADDITIONAL INFORMATION ICSC: 1553 STARCH (C) IPCS, CEC, 1994
