The corrosive symbol, depicted as a bony hand, is a hazard symbol used to indicate that a product is corrosive. It signifies that the product has the potential to cause burns or harm to the skin, eyes, throat, stomach if touched or swallowed. Proper use and safe storage of corrosive products are essential to ensure personal safety.

A corrosive symbol indicates a chemical that could corrode tissue or other materials it comes into contact with. In many cases, contact to the skin or eyes can result in serious (and possibly permanent) injury. The corrosive symbol can be identified by its unique design; two test tubes pouring substances onto a hand and a black object.
