It belongs to both physical and health hazard group

Note: Chemicals that corrode metals and harm the skin and eye.

Corrosives are materials that can attack and chemically destroy exposed body tissues. Corrosives can also damage or even destroy metal. They begin to cause damage as soon as they touch the skin, eyes, respiratory tract, digestive tract, or the metal. They might be hazardous in other ways too, depending on the particular corrosive material.

Most corrosives are either acids or bases. Common acids include hydrochloric acid, sulfuric acid, nitric acid, chromic acid, acetic acid and hydrofluoric acid. Common bases are ammonium hydroxide, potassium hydroxide (caustic potash) and sodium hydroxide (caustic soda).

Other chemicals can be corrosive too. Check the supplier labels on chemical product containers.

It is wise to treat unknown materials as very hazardous until they are positively identified.

Corrosive materials are present in almost every workplace. Acids, bases (which include caustics or alkalis), and other chemicals may be corrosive. Everyone who works with corrosives must be aware of their hazards and how to work safely with them.
