Det er alment kendt at oxygen underst\u00f8tter forbr\u00e6nding. Men hvordan g\u00e5r det, n\u00e5r forskellige substanser uds\u00e6ttes for oxygen? Her beskriver vi, hvad der sker, n\u00e5r oxygen kommer i kontakt med olie og fedt, og hvordan risiciene skal minimeres.<\/strong><\/h5>\n

En lille gnist er nok<\/strong><\/p>\n

Olier og andre sm\u00f8remidler indeholder som regel forskellige kulbrinter, et perfekt br\u00e6ndstof i kombination med oxygen, som jo er yderst oxiderende. Med disse to komponenter til stede er en gnist nok til at skabe foruds\u00e6tninger for en n\u00e6rmest eksplosiv brand. Selv sm\u00e5 m\u00e6ngder fedt\/olie kan reagere p\u00e5 oxygen. Til og med selvant\u00e6nding kan forekomme i visse tilf\u00e6lde. Endnu v\u00e6rre bliver det, hvis komprimeret oxygen kommer i kontakt med fedt eller olie, f.eks. i en regulator eller i en r\u00f8rinstallation, hvor trykst\u00f8d og s\u00e5kaldt adiabatisk kompression kan for\u00e5rsage ant\u00e6nding.<\/p>\n

Minimere risikoen<\/strong><\/p>\n

Hvordan skal man s\u00e5 minimere risiciene ved h\u00e5ndtering af oxygen? Det er rent faktisk enkelt. S\u00f8rg for at undg\u00e5 fedt og olie i forbindelse med oxygen. Men hvordan g\u00f8r man det i praksis? I mange tilf\u00e6lde har man ikke styr p\u00e5, hvordan ventiler, regulatorer og andre gasforsyningskomponenter er smurte. En pludselig oxygenl\u00e6kage i slanger og andet udstyr kan fx f\u00e5 dramatiske f\u00f8lgevirkninger, hvis fedt findes i n\u00e6rheden.<\/p>\n

Nogle enkle tips<\/strong><\/p>\n

Vi \u00f8nsker ikke at overdrive risiciene. Med korrekt h\u00e5ndtering og det rette udstyr skabes foruds\u00e6tningerne for sikker brug af oxygen. Her f\u00f8lger nogle enkle tips, som giver \u00f8get sikkerhed ved brug af oxygen:<\/p>\n

    \n
  1. Sm\u00f8r aldrig regulatorer, ventiler (og andet udstyr, som kommer i kontakt med oxygen) med olie og fedt. Skal mange bruge sm\u00f8remiddel, skal man anvende specialfedt\/-olie, som er beregnet til at blive brugt sammen med oxygen. S\u00f8rg for at sikre, at alle komponenter i gasforsyningssystemet er godkendt til at blive brugt sammen med oxygen.<\/li>\n
  2. Kontroll\u00e9r slanger og tilslutninger med j\u00e6vne mellemrum for at undg\u00e5 l\u00e6kage. S\u00f8rg for, at alle serviceaftaler p\u00e5 gasforsyningssystemet og eventuelle gasvogne overholdes. Selv den lille gasvogn er omfattet af loven om egenkontrol.<\/li>\n
  3. Selv sm\u00e5 fedt- og oliem\u00e6ngder kan v\u00e6re problematiske. S\u00f8rg for, at t\u00f8j, h\u00e6nder og eventuelt v\u00e6rkt\u00f8j er rengjort og affedtet ved arbejde med oxygen.<\/li>\n
  4. \u00c5bn oxygenflaskens ventil forsigtigt.<\/li>\n<\/ol>\n
