H302

H302 is a hazard statement used in the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). It indicates that a substance or mixture is harmful if swallowed. This classification is assigned based on toxicological data, typically from animal studies, that demonstrate adverse health effects occurring after oral ingestion.

The H302 hazard statement is accompanied by a signal word, which is usually "Warning". The pictograms associated with H302 can vary depending on the severity of the hazard and other classifications the substance may possess, but commonly include the exclamation mark pictogram.

Substances classified as H302 require specific precautionary statements on their labels and Safety Data Sheets (SDS). These statements provide guidance on how to handle the substance safely and what to do in case of accidental ingestion. Examples of precautionary statements include avoiding eating, drinking or smoking when using the product and calling a poison center or doctor if swallowed.

The classification of a substance as H302 means it poses a moderate level of acute oral toxicity. It is important for consumers and industrial users to be aware of this hazard to take appropriate protective measures and ensure safe handling and storage.
