British Standards Institution (BSI)

The British Standards Institution (BSI) is the UK National Body providing the organisation, facilities and structure for the preparation of UK National Standards.

British Standards Online is the most authoritative current site for all BSI publications.

The documents published by BSI currently covered in this Level 3 Guidance can be found on the British Standards Website:

Health & Safety staff can readily gain information regarding British Standards, by accessing the HSE Intranet site, going into HSE Information Services, clicking on the British Standards Online link, and reading the HSE Guidance that it contains.

British Standards Online has three levels of user access:
