SDS Studio™Definition: A hazard statement is a standard phrase from CLP Annex III, coded H200 to H420, that describes the nature of a hazard, for example H315 Causes skin irritation.
H2xx codes cover physical hazards, H3xx health hazards and H4xx environmental hazards. Each code has an official wording in every EU language that must not be paraphrased.
H statements appear in SDS sections 2 and 16 and on the label.
