I roto i te umanga hikohiko e tere whanake ana, he tukanga nui te hanga papa hiko tānga (PCB) e hiahia ana ki te tika me te pono. Ko ngā poraka mīhini karāhe tētahi o ngā toa rongonui o te umanga, ā, he mea nui tā rātou mahi ki te whakarite i te tika me te kounga o te hanga PCB.
He rongonui ngā turanga mīhini karāhe mō tō rātou pumau me te pakari. Kāore i rite ki ngā rauemi tuku iho, kāore te karāhe e ngāwari ki te horapa me te wiri i te wera, ka pā kino ki te tika o te tukanga mīhini. I roto i te hanga PCB, ka taea e ngā manawanui te iti noa iho i te torutoru maikorona, ā, ahakoa te iti rawa o te pekanga ka arahi ki ngā hapa, te pikinga o ngā utu me ngā whakaroa. Mā te whakamahi i te turanga mīhini karāhe, ka taea e ngā kaihanga te pupuri i tētahi tūāpapa pumau, te whakaiti i ēnei mōrearea me te whakarite kia hangaia ia PCB ki ngā paerewa teitei rawa atu.
Hei tāpiritanga, nā ngā āhuatanga taiao o te karāhe ka roa te mau. Ka ātete ki te pakaru me te haehae, ka waiho hei whiringa pai mō ngā taiao whakaputa nui. Ko te tikanga o tēnei pakari he iti ake ngā utu tiaki me te iti ake o te wā whakatā, ka taea ai e ngā kaihanga te arotau i ngā mahi me te whakapiki ake i te hua whānui.
Ko tētahi atu painga nui o ngā turanga mīhini karāhe ko tōna kaha ki te mimiti i ngā wiri. I roto i te taiao hanga, he maha ngā wā ka puta he wiri i ngā mīhini ka pā ki te tika o te tukanga. Ko te hanganga matotoru o te karāhe ka āwhina ki te whakaiti i ēnei wiri, ka whakarato i tētahi taiao mahi pumau ake mō ngā mīhini e whai wāhi ana ki te hanga PCB.
Hei whakamutunga, kāore e taea te whakanui rawa i te hiranga o ngā poraka mīhini karāhe i roto i te hanga PCB. Nā tō rātou pumau, tō rātou roa, me ō rātou āhuatanga mimiti-ru, he mea nui ēnei hei whakatutuki i te tino tika e hiahiatia ana e ngā hikohiko hou. I te mea kei te tipu haere tonu te hiahia mō ngā PCB uaua ake, kiato ake, ko te haumi ki ngā poraka mīhini karāhe ka tino whakapiki ake i ngā kaha hanga me te whakarite i te hanga o ngā wāhanga hiko kounga teitei.
