The cylinders used for this purpose are called stage cylinders, and they are usually provided with a standard regulator and a submersible pressure gauge, and are usually left at the stop with the regulator pressurised, but the cylinder valve turned off to minimise the risk of gas loss. Similar cylinders are carried by the divers when the route back is not secure. They are commonly mounted as <i>sling cylinders</i>, clipped to D-rings at the sides of the diver's harness.<sup id="cite_ref-dir2006_53-0" class="reference"><a href="#cite_note-dir2006-53"><span class="cite-bracket">[</span>53<span class="cite-bracket">]</span></a></sup> </p><p>Scuba divers take great care to avoid breathing oxygen enriched "deco gas" at great depths because of the high risk of <a href="/wiki/Oxygen_toxicity" title="Oxygen toxicity">oxygen toxicity</a>.

This allows an attendant to be locked in or out during treatment of the occupant(s) of the main chamber. There is usually also a medical lock, which serves a similar function but is much smaller. This is used to transfer medical material, food and specimens into and out of the main chamber while it is under pressure. Most deck decompression chambers are fitted with built-in breathing systems (BIBS), which supply an alternative breathing gas to the occupants (usually oxygen), and discharge the exhaled gas outside the chamber, so the chamber gas is not excessively enriched by oxygen, which would cause an unacceptable fire hazard, and require frequent flushing with chamber gas (usually air).<sup id="cite_ref-US_Navy_Diving_Manual_Revision_6_Ch21_57-0" class="reference"><a href="#cite_note-US_Navy_Diving_Manual_Revision_6_Ch21-57"><span class="cite-bracket">[</span>57<span class="cite-bracket">]</span></a></sup> </p><p>A deck decompression chamber is intended for surface decompression and emergency hyperbaric treatment of divers, but can be used for other hyperbaric treatment under the appropriate supervision of hyperbaric medical personnel.<sup id="cite_ref-US_Navy_Diving_Manual_Revision_6_Ch21_57-1" class="reference"><a href="#cite_note-US_Navy_Diving_Manual_Revision_6_Ch21-57"><span class="cite-bracket">[</span>57<span class="cite-bracket">]</span></a></sup> </p><p>Portable or mobile one and two occupant single compartment chambers are not generally intended for routine surface decompression, but may be used in an emergency.<sup id="cite_ref-US_Navy_Diving_Manual_Revision_6_Ch21_57-2" class="reference"><a href="#cite_note-US_Navy_Diving_Manual_Revision_6_Ch21-57"><span class="cite-bracket">[</span>57<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading3"><h3 id="Dry_bells_and_Saturation_systems">Dry bells and Saturation systems</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Decompression_equipment&action=edit&section=28" title="Edit section: Dry bells and Saturation systems"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:US_Navy_010707-N-3093M-003_Diver_Transfer_Capsule.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/7/70/US_Navy_010707-N-3093M-003_Diver_Transfer_Capsule.jpg/220px-US_Navy_010707-N-3093M-003_Diver_Transfer_Capsule.jpg" decoding="async" width="220" height="308" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/7/70/US_Navy_010707-N-3093M-003_Diver_Transfer_Capsule.jpg/330px-US_Navy_010707-N-3093M-003_Diver_Transfer_Capsule.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/7/70/US_Navy_010707-N-3093M-003_Diver_Transfer_Capsule.jpg/440px-US_Navy_010707-N-3093M-003_Diver_Transfer_Capsule.jpg 2x" data-file-width="1500" data-file-height="2100" /></a><figcaption>Personnel transfer capsule, closed bell, or dry bell.</figcaption></figure> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Caisson_de_recompression.JPG" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/d/d4/Caisson_de_recompression.JPG/220px-Caisson_de_recompression.JPG" decoding="async" width="220" height="165" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/d/d4/Caisson_de_recompression.JPG/330px-Caisson_de_recompression.JPG 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/d/d4/Caisson_de_recompression.JPG/440px-Caisson_de_recompression.JPG 2x" data-file-width="4724" data-file-height="3543" /></a><figcaption>Part of a saturation system: On the left is a part of the living space with a medical lock in the foreground.

The entire system is managed from a control room, commonly referred to as the "van", where depth, chamber atmosphere and other system parameters are monitored and controlled. The diving bell is the elevator or lift that transfers divers from the system to the work site. Typically, it is mated to the system utilizing a removable clamp and is separated from the system tankage bulkhead by a trunking space, a kind of short tunnel, through which the divers transfer to and from the bell. At the completion of work or a mission, the saturation diving team is decompressed gradually back to <a href="/wiki/Atmospheric_pressure" title="Atmospheric pressure">atmospheric pressure</a> by the slow venting of system pressure, at rates of about of 15 to 30 msw (50 to 100 fsw) per day, (schedules vary).
