International Chemical Safety Cards ZINC OXIDE ICSC: 0208 ZINC OXIDE Zinc white Zinc monoxide C.I. Pigment white 4 ZnO Molecular mass: 81.4 CAS # 1314-13-2 RTECS # ZH4810000 ICSC # 0208 TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Not combustible. In case of fire in the surroundings: all extinguishing agents allowed. EXPLOSION EXPOSURE PREVENT DISPERSION OF DUST! INHALATION Headache. Nausea. Vomiting. Weakness. Chills. Fever. Symptoms may be delayed (see Notes). Local exhaust or breathing protection. Fresh air, rest. Refer for medical attention. SKIN Protective gloves. EYES Safety goggles or eye protection in combination with breathing protection if powder. 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. Rinse mouth. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place (extra personal protection: P2 filter respirator for harmful particles). SEE IMPORTANT INFORMATION ON BACK ICSC: 0208 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities © IPCS CEC 1993 No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and IDLH values.

International Chemical Safety Cards ZINC OXIDE ICSC: 0208 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: ODOURLESS WHITE POWDER OR CRYSTALS. PHYSICAL DANGERS: CHEMICAL DANGERS: Reacts violently with aluminium and magnesium powders, and with chlorinated rubber on heating causing fire and explosion hazard. OCCUPATIONAL EXPOSURE LIMITS (OELs): TLV: ppm; 5 mg/m3 (as TWA) as fume; 10 mg/m3 (STEL) as fume (ACGIH 1994-1995). TLV (as dust): ppm; 10 mg/m3 (as TWA) (ACGIH 1994-1995). MAK: ppm; 5 mg/m3; Dust III,5a (1993). OSHA PEL: TWA 5 mg/m3 (fume) TWA 15 mg/m3 (total dust) TWA 5 mg/m3 (resp dust) NIOSH REL: Dust: TWA 5 mg/m3 C 15 mg/m3 Fume: TWA 5 mg/m3 ST 10 mg/m3 NIOSH IDLH: 500 mg/m3 ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol of dust and fume, and by ingestion. INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly. EFFECTS OF SHORT-TERM EXPOSURE: The substance irritates the respiratory tract. Inhalation of dust or fume may cause metal fume fever. The effects may be delayed. See Notes. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged inhalation exposure may cause asthma. PHYSICAL PROPERTIES Melting point: 1975°C Relative density (water = 1): 5.6 Solubility in water: none ENVIRONMENTAL DATA N O T E S The symptoms of metal fume fever do not become manifest until a few hours have passed.
