United Kingdom data development

The literature contains several examples of fault trees that have been developed for specific situations. For example, the Health and Safety Executive of the United Kingdom has developed a fault tree for the BLEVE of a butane storage bullet (Blything and Reeves, 1988). They consider the ways in which a leak may occur and progress to a BLEVE and assign failure data to arrive at a top event frequency in the range of 10 to 10 /vessel-year. Other examples can be found in CCPS (1989a). 

PPDS (Physical Property Data Service) was originally developed in the United Kingdom by the Institution of Chemical Engineers and the National Physical Laboratory. It is now available as a Microsoft Windows version from NEL, a division of the TUV Sudde-untschland Group (www.nel.uk). PPDS is made available to universities at a discount. 

Crop areas treated and statistical data have not been recorded accurately in many parts of Europe. However, the development of cropping systems and agricultural technology across the continent was similar to that in the United Kingdom (UK), where accurate records are available for at least the last 150 years. 

At present there are no international Antarctic environmental data bases per se, although many organisations and individuals within the SCAR membership hold relevant data. In addition, environmental data bases are known to be in various stages of development in Argentina, Chile, Italy, New Zealand, United Kingdom and the United States, and possibly in other countries.
