Hazard statements, precautionary statements and signal words

Hazard statements

A hazard statement is a phrase that describes the nature of the hazard in the substance or mixture. A hazard statement will be determined by the application of the classification criteria.

Examples of hazard statements include:

  • causes serious eye damage
  • toxic if swallowed
  • toxic to the aquatic life with long lasting effects
  • may cause allergy or asthma symptoms or breathing difficulties if inhaled

Precautionary statements

A precautionary statement is a phrase that describes the recommended measure(s) to minimise or prevent adverse effects resulting from exposure to a hazardous substance or mixture due to its use or disposal.

Examples of precautionary statements include:

  • wear eye protection
  • do not eat, drink or smoke when using this product
  • avoid release to the environment
  • in case of inadequate ventilation wear respiratory protection

Suppliers determine the appropriate precautionary statements (usually no more than six) based on the required hazard statements.

Signal words

The GB CLP Regulation includes two signal words: 'Danger' and 'Warning'.

If the chemical has a more severe hazard, the label includes the signal word 'Danger'; in case of less severe hazards, the signal word is 'Warning'.
