Changes in Chemical Hazard Classifications

The European Chemicals Association (ECHA), from which RiskAssess sources its classifications of chemicals, continually updates its chemical hazard information as new data become available. This means that hazard statements, pictograms and sometimes even signal words for chemicals may change over time. The purpose of this webpage is to summarise the significant changes in chemical hazard classifications, commencing 2026, so that RiskAssess users can be alerted to the changes. This webpage will be updated at each future update of the chemical database.

Schools should replace labels on "decanted or transferred hazardous chemicals" and on chemical solutions when there is a significant change to the chemical classification.

Sodium bromide

Sodium bromide now has hazard statements:

  • May cause drowsiness or dizziness
  • May cause damage to organs through prolonged or repeated exposure
  • Suspected of damaging fertility or the unborn child

The first two hazard statements are new, but are not likely to be an issue in the school situation. The third hazard statement has been reduced from "May damage fertility or the unborn child" to "Suspected of damaging fertility or the unborn child", so the substance is now regarded as less likely to cause reproductive issues.

Salicylic acid

Salicylic acid now has hazard statements:

  • Harmful if swallowed
  • Causes serious eye damage
  • Suspected of damaging the unborn child

The first and second hazard statements are the same as before. The third hazard statement is new and indicates a possible reproductive hazard. However, salicylic acid occurs in many fruits and vegetables, so intake of small quantities may be harmless. Aspirin is metabolised to salicylic acid in the human body and methyl salicylate is used in ointments. Care should be taken when handling solid salicylic acid.
