Uruhande rwimbere ninyuma yumuzenguruko wa PCB ni igice cyikirere. Mugukora imirongo ya PCB, ntakibazo niba urwego rwumuringa rwatoranijwe kubiciro bifatika cyangwa imibare ibiri yongeyeho no gukuramo, ibisubizo byanyuma ni hejuru yubusa. Nubwo imitungo yumuringa itinshi yishimye nka alumini, icyuma, mannesium, nibindi, munsi yumuringa wa barafu, umuringa wera na ogisijeni byoroshye cyane kuri okiside; Urebye ko hariho imyuka ya CO2 n'umwuka w'amazi mu kirere, hejuru y'umuringa wose nyuma yo guhura na gaze, reaction ya Redox bizaba vuba. Urebye ko ubunini bw'umuringa mu muzunguruko wa PCB ari atoroshye, umuringa nyuma yuko amashanyarazi azaba azaba ibintu byinshi by'amashanyarazi, bizagirira nabi ibikoresho by'amashanyarazi biranga imirongo yose ya PCB.

Kugirango urusheho kubuza okidation yumuringa, kandi kugirango utandukanye gusudira ibice byumuzunguruko mugihe cya PCB mugihe cyo gusudira amashanyarazi, kandi kugirango ukomeze neza ubuso bwumuzunguruko wa PCB. Ikotizwa ryubwubatsi irashobora guhuzwa byoroshye hejuru yumuzunguruko wa PCB, bikaviramo ubunini bwurwego rukingira rugomba kuba ruto rugomba gucikamo kandi rukandagura imiyoboro y'umuringa na gaze. Iyi shusho yitwa umuringa, nibikoresho fatizo bikoreshwa ni mask yumugurisha
