Arbeid i dårlig ventilerte rom, arbeid i siloer eller gjødselkjellere er typiske steder, og ikke minst der hvor det brukes gasser som fortrenger oksygen. En enkel test på om oksygeninnholdet i luften er nede på et kritisk nivå, er å tenne et stearinlys. Hvis det brenner, er sjansene for å overleve gode. Hvis det slukner, er oksygeninnholdet i luften under 10-12 %, og det er stor fare for at hjernefunksjonene svekkes og at bevisstløshet vil inntreffe. </p> <div class="mw-heading mw-heading2"><h2 id="Se_også"><span id="Se_ogs.C3.A5"></span>Se også</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Oksygen&veaction=edit&section=9" title="Rediger avsnitt: Se også" class="mw-editsection-visualeditor"><span>rediger</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Oksygen&action=edit&section=9" title="Rediger kildekoden til seksjonen Se også"><span>rediger kilde</span></a><span class="mw-editsection-bracket">]</span></span></div> <ul><li><a href="/wiki/Oksygenbehandling" title="Oksygenbehandling">Oksygenbehandling</a> (medisinsk oksygen)</li> <li><a href="/wiki/Flytende_oksygen" title="Flytende oksygen">Flytende oksygen</a></li> <li><a href="/w/index.php?title=Kalkogen&action=edit&redlink=1" class="new" title="Kalkogen (ikke skrevet ennå)">Kalkogen</a></li> <li><a href="/wiki/Oksygenforbindelser" title="Oksygenforbindelser">Oksygenforbindelser</a></li> <li><a href="/wiki/Ozonlaget" title="Ozonlaget">Ozonlaget</a></li></ul> <div class="mw-heading mw-heading2"><h2 id="Fotnoter">Fotnoter</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Oksygen&veaction=edit&section=10" title="Rediger avsnitt: Fotnoter" class="mw-editsection-visualeditor"><span>rediger</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Oksygen&action=edit&section=10" title="Rediger kildekoden til seksjonen Fotnoter"><span>rediger kilde</span></a><span class="mw-editsection-bracket">]</span></span></div> <style data-mw-deduplicate="TemplateStyles:r18775549">.mw-parser-output .following-list-style-type-lower-alpha+ol li{list-style-type:lower-alpha}.mw-parser-output .following-list-style-type-upper-alpha+ol li{list-style-type:upper-alpha}.mw-parser-output .following-list-style-type-lower-roman+ol li{list-style-type:lower-roman}.mw-parser-output .following-list-style-type-upper-roman+ol li{list-style-type:upper-roman}.mw-parser-output .following-list-style-type-decimal+ol li{list-style-type:decimal}.mw-parser-output .following-list-style-type-lower-alpha+.mw-references-wrap>ol.references li{list-style-type:lower-alpha!important}.mw-parser-output .following-list-style-type-upper-alpha+.mw-references-wrap>ol.references li{list-style-type:upper-alpha!important}.mw-parser-output .following-list-style-type-lower-roman+.mw-references-wrap>ol.references li{list-style-type:lower-roman!important}.mw-parser-output .following-list-style-type-upper-roman+.mw-references-wrap>ol.references li{list-style-type:upper-roman!important}.mw-parser-output .following-list-style-type-decimal+.mw-references-wrap>ol.references li{list-style-type:decimal!important}</style><div class="ve-conditional-display-block following-list-style-type-lower-alpha"><b>Type nummerering</b></div> <div class="mw-references-wrap"><ol class="references"> <li id="cite_note-1"><b><a href="#cite_ref-1">^</a></b> <span class="reference-text">fra <a href="/wiki/Gresk" title="Gresk">gresk</a> ὀξύς, oxys, «<a href="/wiki/Syre" title="Syre">syre</a>», bokstavelig «skarp», fra smaken av syrer, og -γενής, -genēs, «produsent», bokstavelig «opphav»</span> </li> </ol></div> <div class="mw-heading mw-heading2"><h2 id="Referanser">Referanser</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Oksygen&veaction=edit&section=11" title="Rediger avsnitt: Referanser" class="mw-editsection-visualeditor"><span>rediger</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Oksygen&action=edit&section=11" title="Rediger kildekoden til seksjonen Referanser"><span>rediger kilde</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="mw-references-wrap"><ol class="references"> <li id="cite_note-NASA_(2007)-2"><b><a href="#cite_ref-NASA_(2007)_2-0">^</a></b> <span class="reference-text"><a rel="nofollow" class="external text" href="https://www.nasa.gov/home/hqnews/2007/sep/HQ_07215_Timeline_of_Oxygen_on_Earth.html">«NASA Research Indicates Oxygen on Earth 2.5 Billion Years Ago»</a> <a rel="nofollow" class="external text" href="https://web.archive.org/web/20080313063940/http://www.nasa.gov/home/hqnews/2007/sep/HQ_07215_Timeline_of_Oxygen_on_Earth.html">Arkivert</a> 13. mars 2008 hos <a href="/wiki/Wayback_Machine" title="Wayback Machine">Wayback Machine</a>., pressemelding fra <a href="/wiki/NASA" title="NASA">NASAs</a> hjemmesider, 27. september 2007.
