Summary

This guidance provides help to research establishments and academia on how to comply with their occupational health and safety legal obligations; it also provides additional information to help make improvements to health and safety systems when working with nanomaterials.

This Guidance Note draws attention to the possible health hazards which could result from exposure to particulate nanomaterials. It gives advice on the precautions that may be needed to prevent or adequately control exposure as required by the "Control of Substances Hazardous to Health Regulations (COSHH) 2002" (as amended).

The aim of this document is to give guidance on factors relating to establishing a safe workplace and good safety practice when working with particulate nanomaterials. The document is applicable to a wide range of nanomaterials, including particles, fibres, powders, tubes and wires as well as aggregates and agglomerates.

This guidance is aimed at employers, managers, health and safety advisors, and users of particulate nanomaterials in research and development. It should be read in conjunction with the Approved Code of Practice on COSHH, together with the other literature referred to below and in the Appendices.

The document has been produced taking account of the safety information currently available and is presented in the format of guidance and recommendations to support implementation of suitable protocols and control measures by employers and employee by advocating a precautionary strategy to minimise potential exposure. It is intended that the document will be reviewed and updated on a periodic basis to keep abreast of the evolving nature of the content.
