This leaflet describes how to control exposure to dust at work to avoid ill health.



This guidance describes how to control occupational exposure to manufactured nanomaterials in the workplace. It will help you understand what you need to do to comply with the Control of Substances Hazardous to Health Regulations 2002 (COSHH) (as amended) when you work with these substances.

If you work with nanomaterials this guidance will help you protect your employees. If you run a medium-sized or large business, where decisions about controlling hazardous substances are more complex, you may also need professional advice. This guidance will also be useful for trade union and employee health and safety representatives.

This guidance is specifically about the manufacture and manipulation of all manufactured nanomaterials, carbon nanotubes (CNTs) and other bio-persistent high aspect ratio nanomaterials (HARNs). It has been prepared in response to emerging evidence about the toxicity of these materials.

The control principles described can be applied to all nanomaterials used in the workplace. Any differences in the approach between control of CNTs and other bio-persistent HARNs to any other type of nanomaterials are highlighted in the text.
