Kupopera Mapewa Obiriwira pa DOT Medical Oxygen Cylinders: Chifukwa Chake Ndikofunikira

Ngati mudawonapo silinda ya okosijeni yachipatala, mwina mwazindikira kuti ili ndi kupopera kwa mapewa obiriwira. Ichi ndi gulu la utoto wozungulira pamwamba pa silinda yomwe imaphimba pafupifupi 10% ya malo ake. Silinda yotsalayo ikhoza kukhala yosapenta kapena kukhala ndi mtundu wosiyana malinga ndi wopanga kapena wopereka. Koma chifukwa chiyani utsi wa mapewa ndi wobiriwira? Ndipo gasi wamkati amatanthauza chiyani?

Kupopera kwa mapewa obiriwira ndi mtundu wodziwika bwino wamasilinda a oxygen ku United States. Imatsatira malangizo a Compressed Gas Association (CGA) Pamphlet C-9, yomwe imatchula mitundu yamitundu yosiyanasiyana yamafuta opangira mankhwala. Mtundu wobiriwira umasonyeza kuti mpweya mkati ndi mpweya, umene ndi oxidizer kapena moto ngozi. Oxygen imatha kupanga zinthu zomwe sizimayaka kapena zomwe siziyaka mumlengalenga kuti zipse ndi kuyaka m'malo okhala ndi okosijeni wambiri. Chilengedwe ichi chimapangidwa ndi mpweya ukuyenda panthawi ya chithandizo komanso kutulutsa kosadziwika. Choncho, masilindala a okosijeni sayenera kuwonetsedwa ndi zinthu zoyatsira moto kapena zinthu zoyaka moto.

Komabe, mtundu wa silinda yokha sikwanira kuzindikira mpweya mkati. Pakhoza kukhala kusiyana kwa mitundu pakati pa mayiko osiyanasiyana kapena ogulitsa. Komanso, masilindala ena amatha kukhala atazilala kapena kuonongeka utoto womwe umapangitsa kuti mtunduwo usamveke bwino. Chifukwa chake, ndikofunikira nthawi zonse kuyang'ana chizindikiro pa silinda yomwe ikuwonetsa dzina, kukhazikika, komanso kuyera kwa gasi. Ndibwinonso kugwiritsa ntchito chowunikira cha oxygen kuti mutsimikizire zomwe zili mkati ndi kuchuluka kwa silinda musanagwiritse ntchito.

Silinda ya okosijeni yachipatala ya DOT ndi mtundu wa silinda yamagetsi yothamanga kwambiri yomwe imatha kusunga mpweya wa mpweya wosamalira odwala m'malo osiyanasiyana. Amalembedwa kuti atchule mtundu wa silinda, kuthamanga kwambiri kudzaza, tsiku loyesa la hydrostatic, woyang'anira, wopanga, ndi nambala ya serial. Zolembazo nthawi zambiri zimadindidwa pamapewa a silinda. Tsiku loyeserera la hydrostatic ndi chizindikiro choyang'anira zikuwonetsa pomwe silinda idayesedwa komaliza komanso yemwe adayesa silindayo. Masilinda a oxygen ambiri amafunikira kuyesedwa zaka zisanu zilizonse. Mayesowa amawonetsetsa kuti silinda imatha kusunga kukakamiza kokwanira.
