Pigment White 4 ZnO Molecular mass: 81.4 ICSC #    0208 CAS #     1314-13-2 RTECS # ZH4810000 EC #         030-013-00-7 April 21, 2004 Peer reviewed 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 PREVENT DISPERSION OF DUST!  •INHALATION Sore throat. Headache. Fever or elevated body temperature. Nausea. Vomiting. Weakness. Chills. Muscular pain. Symptoms may be delayed (see Notes). Local exhaust or breathing protection. Fresh air, rest. Refer for medical attention.  •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 Abdominal pain. Diarrhoea. 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. Personal protection: P2 filter respirator for harmful particles. N symbol R: 50/53 S: 60-61 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 (C) IPCS CEC 1994.

International Chemical Safety Cards ZINC OXIDE ICSC: 0208 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: WHITE POWDER PHYSICAL DANGERS: CHEMICAL DANGERS: Reacts violently with with aluminium and magnesium powders, and with chlorinated rubber on heating causing fire and explosion hazard. OCCUPATIONAL EXPOSURE LIMITS: TLV: (as respirable fraction) 2 mg/m³ as TWA; (ACGIH 2004). TLV: (as respirable fraction) 10 mg/m³ as STEL; (ACGIH 2004). MAK: (as fume) 1 mg/m³, Respirable fraction; Peak limitation category: I(1); (DFG 2003). 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 and by ingestion. INHALATION RISK: A harmful concentration of airborne particles can be reached quickly especially for zinc oxide fume particles. EFFECTS OF SHORT-TERM EXPOSURE: Inhalation of fumes may cause metal fume fever. The substance as a fume is irritating to the respiratory tract . The effects may be delayed. See Notes. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Melting point: 1975°C Density: 5.6 g/cm3 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. Card has been partly updated in October 2004. See sections Occupational Exposure Limits, EU classification, Emergency Response. ADDITIONAL INFORMATION ICSC: 0208 ZINC OXIDE (C) IPCS, CEC, 1994
