Zinc Oxide

Crude zinc oxide is a yellow-gray granular solid with no odor. It is insoluble in water. The primary hazard is the threat posed to the environment. Immediate steps should be taken to limit its spread to the environment. Prolonged inhalation of the dust may result in metal fume fever with symptoms of chills, fever, muscular pain, nausea and vomiting. — CAMEO Chemicals
