For years of compressed air work tunneling experience, we suggested that in modern compressed air work with TBM, oxygen decompression tables is safe and effective to control Decompression illness arised from compressed air work.

While, Trimix bounce and Trimix Saturation work can also be very effective and safe in High Pressure Compressed Air Work in modern Tunnel Boring Machine (TBM) tunneling.
