COSHH stands for “Control of Substances Hazardous to Health.”

Quick meaning

  • COSHH is a set of UK regulations that protect people at work from harmful substances like chemicals, fumes, dust, mists, gases, and biological agents.
  • The rules require employers to identify hazardous substances, assess the risks, and put controls in place so exposure is reduced and health is protected.

Why COSHH matters

  • Unsafe exposure can damage lungs, skin, eyes, internal organs, or even cause long‑term diseases such as certain cancers or lung conditions.
  • COSHH makes it a legal duty (in the UK) to manage these risks properly, and breaching the regulations can lead to serious penalties for organisations.
