Radioactive material labels show the traditional trefoil symbol for radioactivity. They're also accompanied by a Roman numeral (I, II, or III) indicating
the transport category, which relates to the level of radiation emitted.
- Class 8: Corrosive Substances
Corrosive labels feature a hand and a metal bar, both being eaten away by a substance, indicating that the material can corrode metals and skin.
