Corrosion (GHS05)

Corrosion (GHS05)
Causes severe skin burns and eye damage, or corrodes metal.

What it looks like

Two test tubes pouring liquid, one onto a hand and one onto a bar of metal, both being eaten away.

What it means

Drain cleaner, oven cleaner, descaler, strong bleach and battery acid. The important distinction from the exclamation-mark pictogram is depth and irreversibility: corrosive means tissue is destroyed rather than irritated, and eye contact can mean permanent damage in seconds. Rinse for a sustained period — the guidance for eyes is at least fifteen minutes of running water — and do not try to neutralise an alkali with an acid or the reverse, because the reaction generates heat in the wound.

Defined by UN GHS / EU CLP / OSHA HazCom. Where a symbol differs between standards, the difference is described above rather than resolved — both versions are in circulation on real labels.
