The U.S. Centers for Disease Control and Prevention says sulfuric acid is a corrosive and toxic substance that is destructive to the skin, eyes, teeth, and lungs. Severe exposure can result in death.  Workers may be harmed from exposure to sulfuric acid.  

Sulfuric acid is used to produce other chemicals, fertilizers, explosives and glues, to refine petroleum, cure metal, and power lead-based car batteries.
