I-DOT imele uMnyango Wezokuthutha e-United States, futhi ibhekisela eqoqweni lemithethonqubo namazinga alawula ukuklanywa, ukwakhiwa, nokuhlolwa kwezinto ezihlukahlukene ezithinta ezokuthutha, okuhlanganisa namasilinda e-LPG. Uma ubhekisela kusilinda se-LPG, i-DOT ngokuvamile ihlobene nemithetho ethize ye-DOT esebenza kumasilinda asetshenziselwa ukugcina noma ukuthutha i-liquefied petroleum gas (LPG).
Nakhu ukuhlukaniswa kwendima ye-DOT ngokuhlobene namasilinda e-LPG:
1. Imininingwane ye-DOT yamasilinda
I-DOT ibeka amazinga okwenziwa, ukuhlolwa, kanye nokulebula kwamasilinda asetshenziselwa ukugcina izinto eziyingozi, okuhlanganisa ne-LPG. Le mithethonqubo ihloselwe ngokuyinhloko ukuqinisekisa ukuphepha ngesikhathi sokuthutha nokuphathwa kwamasilinda egesi.
Amasilinda Agunyazwe I-DOT: Amasilinda e-LPG aklanyelwe ukusetshenziswa futhi ezokuthutha e-US kufanele ahlangabezane nokucaciswa kwe-DOT. Lawa masilinda avame ukugxivizwa ngezinhlamvu “DOT” elandelwa inombolo ethile ekhombisa uhlobo nezinga lesilinda. Isibonelo, isilinda se-DOT-3AA iyindinganiso yamasilinda ensimbi asetshenziselwa ukugcina amagesi acinene njenge-LPG.
2. I-DOT Cylinder Marking
Isilinda ngasinye esigunyazwe i-DOT sizoba nezimpawu ezigxivizwe ensimbi ezinikeza ulwazi olubalulekile mayelana nokucaciswa kwalo, okuhlanganisa:
Inombolo ye-DOT: Lokhu kubonisa uhlobo oluthile lwesilinda nokuhambisana kwayo nezindinganiso ze-DOT (isb., DOT-3AA, DOT-4BA, DOT-3AL).
Inombolo Yomkhiqizo: Isilinda ngasinye sinesikhombi esihlukile.
Uphawu Lomkhiqizi: Igama noma ikhodi yomkhiqizi owenze isilinda.
Usuku Lokuhlola: Amasilinda kufanele ahlolwe njalo ukuze avikeleke. Isitembu sizobonisa idethi yokugcina yokuhlola kanye nedethi yokuhlola elandelayo (imvamisa njalo eminyakeni emi-5-12, kuye ngohlobo lwesilinda).
Isilinganiso Sokucindezela: Ingcindezi enkulu lapho isilinda esiklanyelwe ukusebenza ngokuphephile.
3. Amazinga we-DOT Cylinder
Imithetho ye-DOT iqinisekisa ukuthi amasilinda akhiwe ukuze amelane ngokuphepha nezingcindezi eziphezulu. Lokhu kubaluleke kakhulu ku-LPG, egcinwa njengoketshezi ngaphansi kwengcindezi ngaphakathi kwamasilinda. Ikhava yezindinganiso ze-DOT:
Impahla: Amasilinda kufanele enziwe ngezinto eziqine ngokwanele ukumelana nokucindezela kwegesi ngaphakathi, njengensimbi noma i-aluminium.
Ubukhulu: Ubukhulu bezindonga zensimbi kufanele buhlangabezane nezidingo ezithile zamandla nokuqina.
Izinhlobo zamavalvu: Ivalve yesilinda kufanele ihambisane nemibandela ye-DOT ukuze kuqinisekiswe ukuphathwa ngendlela efanele nokuphepha lapho isilinda sixhunywe ezintweni zikagesi noma sisetshenziselwa ukuthutha.
4. Ukuhlola Nokuhlola
Ukuhlolwa kwe-Hydrostatic: I-DOT idinga ukuthi wonke amasilinda e-LPG ahlolwe i-hydrostatic njalo eminyakeni emi-5 noma eyi-10 (kuye ngokuthi uhlobo lwesilinda). Lokhu kuhlola kuhilela ukugcwalisa isilinda ngamanzi nokuyicindezela ukuze kuqinisekiswe ukuthi ingakwazi ukubamba igesi ngokuphepha ngomfutho odingekayo.
Ukuhlola Okubonakalayo: Amasilinda kufanele futhi ahlolwe ngokubona umonakalo njengokugqwala, ukubola, noma imifantu ngaphambi kokuba asetshenziswe.
5. I-DOT iqhudelana namanye Amazinga Omhlaba
Nakuba imithetho ye-DOT isebenza ngokuqondile e-US, amanye amazwe anezindinganiso zawo zamasilinda egesi. Ngokwesibonelo:
I-ISO (Inhlangano Yomhlaba Wonke Yokumisa): Amazwe amaningi, ikakhulukazi eYurophu nase-Afrika, alandela izindinganiso ze-ISO zokukhiqiza nokuthuthwa kwamasilinda egesi, afana namazinga e-DOT kodwa angase abe nomehluko othile wesifunda.
I-TPED (I-Transportable Pressure Equipment Directive): E-European Union, i-TPED ilawula izindinganiso zokuthutha imikhumbi yokucindezela, okuhlanganisa namasilinda e-LPG.
6. Ukucatshangelwa Kokuphepha
Ukuphatha Okufanelekile: Imithetho ye-DOT iqinisekisa ukuthi amasilinda enzelwe ukuphathwa okuphephile, ukunciphisa ingozi yezingozi ngesikhathi sokuthutha noma ukusetshenziswa.
Amavalufu Osizo Oluphuthumayo: Amasilinda kufanele abe nezici zokuphepha njengamavalvu okusiza ukucindezela ukuvimbela ukucindezela ngokweqile okuyingozi.
Ngokufigqiwe:
Imithetho ye-DOT (Umnyango Wezokuthutha) iqinisekisa ukuthi amasilinda e-LPG asetshenziswa e-US ahlangabezana nezindinganiso eziphakeme zokuphepha nokuhlala isikhathi eside. Le mithetho ilawula ukwakhiwa, ukulebula, ukuhlolwa, nokuhlolwa kwamasilinda egesi ukuze kuqinisekiswe ukuthi angaqukatha ngokuphephile igesi enomfutho ngaphandle kokwehluleka. Lawa mazinga asiza futhi ukuqondisa abakhiqizi nabasabalalisi ekukhiqizeni nasekusabalaliseni amasilinda aphephile, athembekile kubathengi.
Uma ubona i-DOT imakwa kusilinda se-LPG, kusho ukuthi isilinda sakhiwe futhi sahlolwa ngokwale mithetho.
