SECTION 2: Hazards identification

Principle Routes of Exposure

1. Inhalation. 2. Mechanical irritation to skin and eyes Carcinogens: Not a NTP/IARC carcinogen. Signs & Symptoms of Exposure: Dry throat, cough, dry itching skin. Human: Excess bulk exposure may cause acute respiratory irritant or dry skin. No chronic hazards. Metal Fume Fever: Excessive inhalation exposure within hours of ZnO formation may cause ‘metal fume fever.’ Symptoms are chills, metallic taste, severe headache. This hazard only exists at the manufacture and not in later handling or use. Symptoms often persist 24 hours. See Section 4, First Aid. Other Human hazard reports: Some users request ZnO with addition of processing aid additives or coatings, most commonly <0.1% content propionic acid, caprylic acid, or mineral oil. Acid content may increase exposed skin irritation. An internet search noted alleged dermatitis or oxide pox with oxides, however, this preparer finds no cases in reputable medical literature data of such conditions caused by zinc oxide products covered by this MSDS. Less than commercial quality, or tech grade, zinc oxide may contain additional impurities requiring exposure considerations not covered by this MSDS. Environmental: ZnO is not water soluble. However if chemically in solution, the net Zn in certain situations is toxic to a limited group of aquatic organisms. \
