What is a 'substance hazardous to health'?

COSHH covers

COSHH covers substances that are hazardous to health. Substances can take many forms and include:

  • chemicals
  • products containing chemicals
  • fumes
  • dusts
  • vapours
  • mists
  • nanotechnology
  • gases and asphyxiating gases and
  • biological agents (germs). If the packaging has any of the hazard symbols then it is classed as a hazardous substance.
  • germs that cause diseases[61] such as leptospirosis or legionnaires disease and germs used in laboratories.

Read more about COSHH and what you need to do[62] and COSHH assessments[63].

COSHH does not cover

because these have their own specific regulations.
