Njengengxenye ebalulekile yawo wonke umshini, i-PCB ngokuvamile ayikwazi ukwakha umkhiqizo we-elekthronikhi, futhi kufanele kube nenkinga yokuxhuma kwangaphandle. Isibonelo, ukuxhumeka kukagesi kuyadingeka phakathi kwama-PCB, ama-PCB nezingxenye zangaphandle, ama-PCB namaphaneli emishini. Ingenye yokuqukethwe okubalulekile komklamo we-PCB ukukhetha ukuxhumana nokuxhumana okungcono kakhulu kokuthembeka, ukwenziwa kwezinto kanye nomnotho. Namuhla, sizoxoxa ngendlela yokuxhuma izixhumi ze-PCB. Ezinsimbini nasezisetshenziswa eziyinkimbinkimbi, ukuxhumana kwezixhumi kuvame ukusetshenziswa. Lesi sakhiwo "sokwakha" asiqinisekisi kuphela ikhwalithi yokukhiqizwa kwemikhiqizo ngobuningi, sinciphisa izindleko zesistimu, kodwa futhi sinikeza lula ukulungisa iphutha nokugcinwa.
Uma okokusebenza kwehluleka, abasebenzi abalungisayo akudingeki bahlole izinga lengxenye (okungukuthi, bahlole imbangela yokwehluleka, futhi balandelele umthombo kungxenye ethile.
Lo msebenzi uthatha isikhathi esiningi). Uma nje kwahlulelwa ukuthi yiliphi ibhodi elingavamile, lingashintshwa ngokushesha, ukuxazulula izinkinga ngesikhathi esifushane kakhulu, ukunciphisa isikhathi sokuphumula, nokuthuthukisa ukusetshenziswa kwemishini. Ibhodi lesifunda elishintshiwe lingalungiswa ngesikhathi esanele futhi lisetshenziswe njengengxenye eyisipele ngemuva kokulungiswa.

1. Uxhumano lwephini elijwayelekile Le ndlela ingasetshenziselwa ukuxhuma kwangaphandle kwe-PCB, ikakhulukazi kumathuluzi amancane. Ama-PCB amabili axhunywe ngezikhonkwane ezijwayelekile. Ama-PCB amabili ngokuvamile ayahambisana noma aqondile, okulula ukuzuza ukukhiqizwa ngobuningi.
2. Isokhethi ye-PCB Le ndlela ukwenza ipulaki ephrintiwe kusukela ekugcineni kwe-PCB. Ingxenye yepulaki yakhelwe ngokuhambisana nobukhulu besokhethi, inombolo yoxhumana nabo, ibanga labathintwayo, indawo yembobo yokubeka, njll., ukufanisa isokhethi ekhethekile ye-PCB. Lapho wenza ibhodi, ingxenye yepulaki idinga ukugqitshwa ngegolide ukuze kuthuthukiswe ukumelana nokugqokwa nokunciphisa ukumelana nokuxhumana. Le ndlela ilula ukuhlanganisa, inokushintshwa okuhle nokusebenza kokugcinwa, futhi ilungele ukukhiqizwa ngobuningi obujwayelekile. Okubi ukuthi izindleko ze-PCB ziyanyuswa, futhi izidingo zokunemba nenqubo yokukhiqiza ye-PCB ziphezulu; ukwethembeka kubi kakhulu, futhi othintana naye ngokuvamile abampofu ngenxa ye-oxidation yengxenye yepulaki noma ukuguga komhlanga wesokhethi. Ukuze kuthuthukiswe ukwethembeka kokuxhumeka kwangaphandle, ucingo olufanayo lokuhola luvame ukuholwa ngokuhambisana ngoxhumana nabo ohlangothini olufanayo noma ezinhlangothini zombili zebhodi lesifunda. Indlela yokuxhuma isokhethi ye-PCB ivamise ukusetshenziselwa imikhiqizo enesakhiwo samabhodi amaningi. Kunezinhlobo ezimbili zohlobo lomhlanga nohlobo lwephinikhodi yesokhethi kanye ne-PCB noma ipuleti eliphansi.
