Use With Hyperbaric Chambers
Commercial diving operators now generally use a closed bell in conjunction with a surface hyperbaric chamber, These have safety and ergonomic advantages and allow decompression to be carried out after the bell has been raised to the surface and back on board the diving support vessel. They are used especially in saturation diving and undersea rescue operations. The diving bell would be connected via the mating flange of an airlock to the deck decompression chamber or saturation system for transfer under pressure of the occupants.

Famous quotes containing the word chambers:
“Why rather, sleep, liest thou in smoky cribs
...
Than in the perfumed chambers of the great,
Under the canopies of costly state,
And lulled with sound of sweetest melody?”
—William Shakespeare (1564–1616)
