Work in a High Pressure Compressed Air environment is defined in Report 10 as “work in compressed air at pressures above historical statutory limits, which in most
countries are between 3 and 4 bar(g), and which involves the use of breathing mixtures other than compressed natural air and can involve the use of saturation techniques”.
This Guide provides information for those new to the topic to better understand some of the concepts covered by Report 10 and its current revision.
