He whānuitia hoki te whakamahinga o ngā mīhini tīwiri ringaringa i roto i te umanga whakatika PCB (Papa Ara-Pānui, papa ara-pūtuhi tā). Kei raro nei ētahi whakamahinga o ngā mīhini tīwiri ringaringa i roto i te umanga whakatika PCB: Huihuinga PCB: He whānuitia te whakamahinga o ngā mīhini tīwiri ringaringa i roto i te tukanga huihui PCB. I runga i te PCB, he maha ngā tīwiri iti me ngā nati me whakakī. Ka taea e ngā tīwiri ringaringa te whakaoti tere me te tika i ēnei mahi, ka whakapai ake i te pai me te kounga o te huihuinga. Whakatika me te Whakarite PCB: I te wā e whakatika ana me te whakarite PCB, me tango me te tāuta ngā tīwiri hei whakatika, hei whakarite rānei i ngā wāhanga. Mā ngā tīwiri ringaringa tēnei tukanga ka māmā ake, ka whai hua ake, ka taea ai te whakakī tere me te wetewete i ngā tīwiri, ka whakaiti i te wā e pau ana ki ngā tukanga whakatika me te whakarite. Ngā Taputapu PCB: He maha ngā taputapu kei runga i te PCB, pērā i ngā totohu wera, ngā hononga me ngā putanga. Ka taea te whakamahi i te tīwiri ringaringa hei tāuta me te tango i ēnei taputapu, kia mau ai, kia pumau ai, kia pai ake ai te pumau me te pono o te PCB. Whakamātautau PCB: I te wā e whakamātautau PCB, me tāuta, me tango rānei ētahi hononga, ētahi atanga whakamātautau rānei. Ka taea te whakamahi i ngā tīwiri ringaringa hei whakaoti tere i ēnei mahi, hei whakapai ake i te pai me te tika o te whakamātautau. I te nuinga o te wā, he mahi nui tā ngā mīhini tīwiri ringaringa i roto i te umanga whakatika PCB. Ka taea e rātou te whakapai ake i te pai o te huihuinga, te kounga me te pumau, te whakaiti i te wā whakatika me te whakarerekētanga, me te whakapai ake i te tika o te whakamātautau. Mā te whakamahi i te mīhini tīwiri ringaringa ka taea te whakapai ake i te mahi hanga me te whakatika PCB me te pono ake.
