COSHH (Control of Substances Hazardous to Health)

COSHH assessments are a specialised type of risk assessment that must be undertaken where there is a risk of someone being exposed to a hazardous substance or biological agent during their work, or as a consequence of a work activity.

The CLP Regulation – came into force in all EU member states, including the UK, on 20 January 2010. The CLP Regulation:

  • adopts in the EU the Globally Harmonised System (GHS) on the classification and labelling of chemicals;
  • applies directly in all EU member states. This means that no national legislation is needed;
  • is overseen by the European Chemicals Agency (ECHA);
  • replaced the Chemicals (Hazard Information and Packaging for Supply) Regulations 2009 – CHIP on 1 June 2015.
