International Chemical Safety Cards CALCIUM STEARATE ICSC: 1506 Calcium distearate Octadecanoic acid, calcium salt Stearic acid, calcium salt C36H70O4•Ca Molecular mass: 607.0 ICSC #    1506 CAS #     1592-23-0 RTECS # WI3000000 November 28, 2003 Peer reviewed TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire. NO open flames. Powder, alcohol-resistant foam, water spray, carbon dioxide. EXPLOSION Finely dispersed particles form explosive mixtures in air. Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding). EXPOSURE  •INHALATION Cough. Local exhaust or breathing protection. Fresh air, rest.  •SKIN  •EYES Redness. 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 Vacuum spilled material. (Extra personal protection: P1 filter respirator for inert particles.)
