BCGA provide a range of publications providing safety information and advice on best practice, as well as guidance on associated legal requirements within the UK. BCGA’s Mission is to promote safety in the use, storage, transportation and handling of industrial, food and medical gases.

BCGA publications are produced by and for the gases industry, but many are also used by their customers.

As BCGA also involve and keep informed government bodies, Competent Authorities and Regulators, such as the Department for Transport and the national Environment Agencies, during the development of these publications they are generally accepted as being an appropriate and safe way of working. As such, they give positive examples of best practice and are recognised for this by the enforcement agencies, such as the Health and Safety Executive. It should be noted that in the event of any legal action, either criminal or civil, the courts are likely to use BCGA documents as a measure of what may be reasonably practicable.

All publications are reviewed and updated on a regular basis, available electronically and can be downloaded for free. Selected publications are only available to BCGA members; please login to gain access. To view a full list of all available BCGA publications click here.

In exceptional circumstances where a printed (hard copy) of a document is required, a charge will be made. If you require a printed document, please contact the BCGA office.
Please note: Printed copies of a publication can take a minimum of 5 working days to be delivered.
