Compressed industrial, food and medical gases improve quality of life and are essential to hundreds of thousands of people in the UK every day.

They are the nation’s ‘invisible industry’ – a multi-billion pound sector employing thousands of people, which makes a huge impact to our economic and social well-being.

The British Compressed Gases Association (BCGA), which has been the sector’s membership body since 1901, has produced this online area to give an insight into the scope and scale of this vital industry.

Compressed Gases

The term “industrial gases” refers to gases such as acetylene, argon, ammonia, carbon dioxide, chlorine, hydrogen, oxygen, nitrogen and a range of other speciality gases, used in a wide range of applications.

Industrial gases are vital for the manufacture of information technology components, as well as key UK industrial sectors including steelmaking, welding, chemical processing, electronics and the scientific sectors. They help keep homes warm and water clean, ensure food stays nutritious, appealing and affordable, and also play a critical role in applications including respiratory care, pain therapies and anaesthesia.
