A common example is checking buoyancy control with a new diving suit, buoyancy compensator, cylinder configuration, or weighting system, or an unfamiliar model of rebreather. Buoyancy testing is done with the cylinders nearly empty, to ensure that the diver can maintain neutral buoyancy at the end of a dive during decompression, even if contingency use has depleted the reserve gas supplies. In many cases, testing new equipment does not require a special dive, as any problems will be noticed immediately, and either fixed or the dive can be safely aborted.<sup id="cite_ref-Class_4_training_standard_73-1" class="reference"><a href="#cite_note-Class_4_training_standard-73"><span class="cite-bracket">[</span>73<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-Class_3_training_standard_74-1" class="reference"><a href="#cite_note-Class_3_training_standard-74"><span class="cite-bracket">[</span>74<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-Class_2_diver_training_standard_75-1" class="reference"><a href="#cite_note-Class_2_diver_training_standard-75"><span class="cite-bracket">[</span>75<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-USNDM_R6_76-1" class="reference"><a href="#cite_note-USNDM_R6-76"><span class="cite-bracket">[</span>76<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Response_to_an_emergency">Response to an emergency</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Diving_activities&action=edit&section=28" title="Edit section: Response to an emergency"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1236090951"><div role="note" class="hatnote navigation-not-searchable">See also: <a href="/wiki/Diving_procedures" title="Diving procedures">Diving procedures</a></div> <p>Both foreseeable and not reasonably foreseeable emergencies can occur during a dive.
