International Chemical Safety Cards CALCIUM MOLYBDATE ICSC: 0992 Calcium molybdenum oxide Calcium molybdate(VI) Molybdic acid, calcium salt (11) CaMoO4 Molecular mass: 200.0 ICSC #    0992 CAS #     7789-82-4 RTECS # EW2975000 April 20, 2007 Validated TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Not combustible. In case of fire in the surroundings: use appropriate extinguishing media. EXPLOSION EXPOSURE  •INHALATION Cough. Sore throat. Local exhaust or breathing protection. Fresh air, rest.  •SKIN Redness. Protective gloves. Remove contaminated clothes. Rinse and then wash skin with water and soap.  •EYES Redness. Pain. Safety goggles Rinse with plenty of water (remove contact lenses if easily possible).  •INGESTION Do not eat, drink, or smoke during work. Rinse mouth. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Personal protection: particulate filter adapted to the airborne concentration of the substance. Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. SEE IMPORTANT INFORMATION ON BACK ICSC: 0992 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994.

International Chemical Safety Cards CALCIUM MOLYBDATE ICSC: 0992 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: WHITE CRYSTALLINE POWDER PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating (at 965°C), producing molybdate oxide fumes. OCCUPATIONAL EXPOSURE LIMITS: TLV: Mo, insoluble compounds, respirable fraction 3 mg/m³ as TWA TLV: Mo, insoluble compounds, inhalable fraction 10 mg/m³ as TWA (ACGIH 2006). MAK: IIb (not established but data is available) (DFG 2006). ROUTES OF EXPOSURE: INHALATION RISK: A nuisance-causing concentration of airborne particles can be reached quickly when dispersed, especially if powdered. EFFECTS OF SHORT-TERM EXPOSURE: May cause mechanical irritation to EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Decomposes at 965 °C Density: 4.4 g/cm3 Solubility in water, g/100 ml at 25°C: (very poor) 0.005 ENVIRONMENTAL DATA N O T E S Health effects of exposure to the substance have not been investigated adequately. Environmental effects from the substance have not been investigated. ADDITIONAL INFORMATION ICSC: 0992 CALCIUM MOLYBDATE (C) IPCS, CEC, 1994
