Ngesikhathi sokwakhiwa, amabhodlela e-oxygen ne-acetylene kufanele agcinwe kude namamitha angu-10 ukusuka endaweni yokuthungela, futhi ibanga phakathi kwamabhodlela e-oxygen ne-acetylene kufanele agcinwe ngaphezu kwamamitha angu-5.Ubude bentambo yokuqala (intambo yokumbondelana) yomshini wokushisela kufanele bube ngaphansi kuka-5m, futhi ubude bocingo lwesibili (i-welding bar wire) kufanele bube ngaphansi kwama-30m.I-wiring kufanele icindezelwe ngokuqinile futhi kufanele kufakwe isembozo sokuvikela esithembekile.Intambo yokushisela izoba kabili endaweni.Amapayipi ensimbi, izikafula zensimbi, ojantshi nezinsimbi zesakhiwo akufanele zisetshenziswe njengocingo oluphansi lweluphu.Akukho monakalo ocingweni lwenduku yokushisela, ukwahlukanisa okuhle.
I-acetylene cylinder encibilikisiwe ekukhiqizeni (ngemuva kwalokhu ebizwa ngokuthi i-acetylene cylinder) kanye nebhomu le-oxygen lisetshenziswa kabanzi ekushiseleni nasekusikeni, futhi livame ukusetshenziswa ngesikhathi esifanayo, i-oxygen yegesi evuthayo, i-acetylene yegesi evuthayo, i-oksijeni ne-acetylene. kanye nezingubo zokugqoka emkhunjini we-pressable transportable, ngokulandelana, ekusetshenzisweni kwenqubo, kunezinkinga ezithile ngamazinga ahlukene, njenge-acetylene cylinder enebhomu le-oxygen elibekwe endaweni efanayo, Akukho ibanga lokuphepha;Isilinda somoya-mpilo kanye nokuthintana nowoyela, isilinda se-acetylene esivundlile, esingamile simile sisetshenziswa;Ukushisa kwebhodlela le-acetylene ngaphezu kuka-40 ℃, umsebenzi ovulekile wasehlobo ngaphandle kokumboza;I-oksijeni, amabhodlela e-acetylene awahlali ngokuhambisana nezinhlinzeko zokucindezelwa okusalayo, lezi zinkinga, ziye zaholela ekuveleni kwenani labantu abalimala.Ngenxa yokuthi i-acetylene encibilikile, kune-acetone ku-cylinder.Uma i-engeli etshekile ingaphansi kwamadigri angu-30, lapho kuvulwa i-valve (ngesikhathi sokusetshenziswa), i-acetone ingase iphume futhi ihlangane nomoya ukuze yakhe ingxube eqhumayo.Umkhawulo wokuqhuma ngu-2.55% kuya ku-12.8% (umthamo).Amasilinda omoya-mpilo aqukethe umoya-mpilo womfutho ophezulu, futhi kunezici ezingaphephile zomzimba namakhemikhali: izici zomzimba: ngemva kokucindezelwa komoyampilo nokucindezela kwanda, kuvame ukulingana nokucindezela komkhathi ozungezile.Uma umehluko wengcindezi phakathi kwe-oxygen ne-atmospheric pressure inkulu, lokhu kuthambekela nakho kuba kukhudlwana.Uma umehluko omkhulu kakhulu wengcindezi ufinyelela ngokushesha kulokhu kulinganisa ngesikhathi esifushane kakhulu endaweni enkulu, wenza lokho okuvame ukubizwa ngokuthi "ukuqhuma".Uma lokhu kulinganisa kufinyelelwa esikhathini eside uma kuqhathaniswa nezimbotshana ezincane, kwakheka "ijethi".Kokubili kungaba nemiphumela emibi kakhulu.Izici zamakhemikhali.Ngenxa yokuthi umoya-mpilo uyinto esekela ukuvutha, uma sekunempahla evuthayo nezimo zokushisa, ukusha okunamandla kungenzeka, ngisho nomlilo oqhumayo.
I-1, "Imithetho yokuhlola ukuphepha kwe-acetylene cylinder encibilikisiwe" i-athikili ye-50 yokusetshenziswa kwebhodlela le-acetylene "uma usebenzisa i-oxygen cylinder nebhodlela le-acetylene, kufanele uzame ukugwema ndawonye; Futhi ibanga lomlilo elivulekile ngokuvamile alikho ngaphansi kwamamitha angu-10 ";Ayikho incazelo ecacile yebanga phakathi kwamabhodlela amabili.
2, "Ukuphepha kokushisela nokusika" GB9448-1999: esetshenziswayo nebanga lendawo yokuthungela likhulu kunamamitha ayi-10, kodwa ibanga phakathi kwamabhodlela e-oksijini ne-acetylene e-China libonakala lingacacile kangako.
3. I-Article 552 ye-Electrical Industry Safety Work Regulations (Izingxenye Ezishisayo NeMechanical) idinga ukuthi "ibanga phakathi kwamasilinda komoyampilo asetshenziswayo namasilinda e-acetylene akufanele libe ngaphansi kwamamitha angu-8".
4. "Imithetho yokushisela igesi (Ukusika) Imithetho Yokusebenza Kokuphepha Komlilo" okwesibili yathi "amasilinda oksijini, amasilinda e-acetylene kufanele abekwe ngokwehlukana, isikhala akufanele sibe ngaphansi kwamamitha angu-5. Ikhodi evamile yokuphepha kwezitshalo ye-Fire Operation HG 23011-1999 imboni yamakhemikhali yasePeople's Republic of China.
