Corrosion (GHS05)

The GHS pictogram for corrosives: chemicals that are corrosive to metals, or that can cause skin corrosion or serious eye damage.

These identify the hazard class a pictogram represents. For handling, storage and first aid, refer to the product's label and safety data sheet.

How to read it

It is GHS05. OSHA’s standard and Canada’s WHMIS assign it to three hazard classes: corrosive to metals, skin corrosion and serious eye damage. In Great Britain it is called Corrosive.

Also searched as: corrosive symbol, GHS05.

Look-alikes

Milder effects on the same parts of the body take a different pictogram. Skin irritation (category 2) and eye irritation (categories 2 and 2A) carry the Exclamation mark (GHS07), not the corrosion pictogram.
