NO open flames. Powder, alcohol-resistant foam, water spray, carbon dioxide . EXPLOSION EXPOSURE PREVENT DISPERSION OF DUST!  •INHALATION Sore throat. Local exhaust or breathing protection. Fresh air, rest.  •SKIN Redness. Protective gloves. Rinse and then wash skin with water and soap.  •EYES Redness. Pain. 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. Personal protection: P1 filter respirator for inert particles. Separated from strong oxidants.

International Chemical Safety Cards FERROCENE ICSC: 1512 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: ORANGE CRYSTALS , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: CHEMICAL DANGERS: On combustion, forms toxic fumes. Reacts violently with ammonium perchlorate or tetranitromethane. Reacts with mercury (II) nitrate. OCCUPATIONAL EXPOSURE LIMITS: TLV: (as Fe) 10 mg/m³ as TWA; (ACGIH 2001). MAK not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation and by ingestion. INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. EFFECTS OF SHORT-TERM EXPOSURE: May cause mechanical irritation. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Boiling point: 249°C Sublimation point: above 100°C Melting point: 173°C Solubility in water: none Vapour pressure, Pa at 40°C: 4 ENVIRONMENTAL DATA N O T E S ADDITIONAL INFORMATION ICSC: 1512 FERROCENE (C) IPCS, CEC, 1994
