Umsebenzi oyinhloko: Ukulondolozwa kokushisa kanye nokulondolozwa okubandayo. Emigodini yokugcina izinto yamatangi okugcina kanye namapayipi athutha izinto ezishisa kakhulu (njengomusi, uwoyela oshisayo), isikhwama sokushisa singanciphisa ukulahleka kokushisa ngaphandle futhi silondoloze ukuzinza kokushisa kwendawo engaphakathi kwemishini. Isibonelo, ikettle yokusabela kwamakhemikhali idinga ukugcina njalo izinga lokushisa lokusabela elingu-150°C. Uma isikhwama sokushisa singashisi, izinga lokushisa lendawo lizokwehla ngenxa yokulahlekelwa ukushisa, okuthinta ukusebenza kahle kokusabela. Kodwa-ke, isikhwama sokushisa singanciphisa izinga lokulahlekelwa ukushisa ngaphezu kuka-30%, sinciphise ngokungaqondile ukusetshenziswa kwamandla kohlelo lokushisa.

Umsebenzi osizayo: Ukuvikela imishini kanye nezingxenye ze-manhole. Ukuvimbela ukuguga kwezingxenye ze-manhole: Kugwema ukuvezwa ngqo kwama-flange e-manhole, ama-gasket, ama-bolt, njll. ezindaweni ezishisa kakhulu, izinga lokushisa eliphansi, ezinomswakama noma ezigqwalisayo. Isibonelo, ngaphansi kwezimo zokusebenza ezishisa kakhulu, ama-bolt avame ukwanda kokushisa kanye nokuguquguquka kokugoba ngenxa yokubhaka isikhathi eside okushisa okuphezulu, okuholela ekwehlulekeni kokuvala. Isikhwama sokuvikela singahlukanisa amazinga okushisa aphezulu, sandise impilo yenkonzo yama-bolt nama-gasket, futhi sinciphise ingozi yokuvuza.

Ukunciphisa ukulahleka kwemishini endaweni: Indawo ezungeze umgodi wemishini ethile (njengama-boiler) ithambekele ekucindezelweni kokushisa ngenxa yokushisa okungalingani, okungase kubangele ukuqhekeka kwegobolondo lemishini ngokuhamba kwesikhathi. Isikhwama sokushisa singenza ukusatshalaliswa kwezinga lokushisa ebusweni bemishini kufane kakhulu futhi kunciphise umonakalo wokucindezeleka kokushisa emzimbeni wemishini.
