I roto i te hanga papa hiko tā (PCB), he mea nui te tika me te roa. Ko tētahi o ngā āhuatanga matua o te tukanga ko te tānga o te PCB, ā, ko te whiriwhiri rauemi mō ngā wāhanga tānga ka pā nui ki te kounga me te whai huatanga o te hanga. E rua ngā rauemi e whakamahia whānuitia ana i tēnei horopaki ko te karāhe me te maitai, he painga me ngā ngoikoretanga o ia mea.
E mōhiotia ana ngā wāhanga o te karāneti mō tō rātou pumau me te pakari. Mā te matotoru o te kōhatu maori ka whakaratohia he turanga pakari e whakaiti ana i te wiri i te wā e tāia ana, ā, ka piki ake te tika me te whakaiti i te kakahu o ngā taputapu tā. He tino whai hua tēnei pumau i roto i ngā tono tere-rahi, ahakoa he iti noa te nekehanga ka taea te whakararuraru me te hapa. Hei tāpiri, he ātete te karāneti ki te whakawhānui wera, e whakarite ana i te mahi pumau i ngā pāmahana rerekē, he mea nui tēnei i roto i ngā taiao e āwangawanga ana te whakaputa wera.
Engari, ko ngā wāhanga maitai te mea e pai ake ana mō tō rātou kaha me te roa. He iti ake te tūponotanga o ngā wāhanga maitai kia pakaru i te karāneti, ā, he mea pono mō te hanga nui. Hei tāpiri, ka taea te mīhini me te whakarite i ngā wāhanga maitai kia tutuki ai ngā whakaritenga motuhake, ka whakaratohia he ngāwari hoahoa e kore e taea e te karāneti te rite. Heoi, he ngāwari te waikura me te pirau o ngā wāhanga maitai, he ngoikoretanga nui tēnei i roto i ngā taiao makuku, waikura matū rānei.
Ina whakatauritea te mahi a te karāhe me te maitai mō ngā mahi tā PCB, ko te whakatau whakamutunga ka whakawhirinaki ki ngā hiahia motuhake o te tukanga hanga. Mō ngā mahi e tino hiahiatia ana te tika me te pumau, ko te karāhe pea te whiringa pai rawa atu. I tetahi atu taha, mō ngā mahi e hiahia ana ki te pakari me te urutau, he pai ake pea te maitai. He mea nui te mārama ki ngā āhuatanga ahurei o ia rauemi mō ngā kaihanga e whai ana ki te arotau i ā rātou tukanga hanga PCB.
