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:

  • Guest: You can search and view results. Click on the Search button or enter a standard number in the Search field to the left.
  • Registered Guest: In addition to searching and viewing results, registering for Free also allows you to view summaries and order hardcopy documents online.
  • Subscriber: Become a Subscriber and get instant unlimited online access to standards. For all HSE staff, information from British Standards is available without having to subscribe.

British Standards

In addition to standards the site also includes:

  • Technical handbooks
  • Codes of practice
  • Guidelines
  • Specifications for products, dimensions, and performance
  • Glossaries

PLEASE NOTE the following definitions as applied to British Standards:

  • Withdrawn: the standard is no longer current
  • Obsolescent: the standard is not recommended for use for new equipment, but is retained to provide for the servicing of existing equipment that is expected to have a long working life.
