Section 3: Hazards Identification
   Inhalation of zinc oxide fume produced from this compound in a fire may cause metal fume fever or zinc
   Emergency Overview:
   shakes consisting of chills, fever, muscular pain, nausea, and vomiting. May cause thermal burns.
   Primary Routes of Exposure:       Eyes, skin, and inhalation of combustion products.    
   Eye Contact:       Direct contact of liquid with the eyes will cause thermal burns and possible blindness.    
   Skin Contact:       Liquid bursts in to flame in air, causing thermal burns to skin.    
   Fume cause burns to the nose, mucous membranes and respiratory tract causing metallic taste, dry throat,
   and chills.
