I roto i te umanga hikohiko e whanake tonu ana, he tukanga nui te hanga papa hiko tā (PCB) e hiahia ana ki te tika me te pono. Ko tētahi huarahi auaha kua piki haere te rongonui i ngā tau tata nei ko te whakamahinga o te karāhe hei rauemi papa i roto i te hanga PCB. Ka tūhuratia e tēnei tuhinga te whai huatanga o te whakamahi i te karāhe i roto i tēnei umanga.
He kōhatu tūturu te karāneti e mōhiotia ana mō tōna pakari me tōna pumau, he maha ngā painga ki ngā rauemi tuku iho. Ko tētahi o ngā painga matua ko tōna pumau i te wera. He maha ngā wā ka pāngia ngā PCB e ngā rerekētanga pāmahana i te wā e whakamahia ana, ka taea ai e rātou te piko, te pakaru rānei. Mā te kaha o te karāneti ki te pupuri i tōna āhua i raro i ngā āhuatanga wera rerekē ka noho tonu ngā PCB me te pono, ka whakaiti i te tūponotanga o ngā pakaru utu nui.
Hei tāpiritanga, ko te pakari o te karāhe he tūāpapa pakari mō ngā hoahoa ara iahiko uaua. Mā tēnei pumau ka taea te whakakaha ake i ngā ātete i roto i te tukanga hanga, ka hua ake he hua kounga teitei ake. Mā te tika ake ka whakaitihia ngā hapa, ka whakaitihia ngā utu whakaputa me te whakapiki ake i te whai huatanga.
Ko tētahi atu āhuatanga hei whakaaroaro ko te roa o te ora o tō papa kōhatu. Kāore i rite ki ētahi atu rauemi ka pirau i te roanga o te wā, he ātete te kōhatu ki te pakaru me te pakaru. Nā tēnei pakari ka taea e ngā kaihanga te whakaroa i te ora o ā rātou taputapu, ka whakaiti i te hiahia mō te whakakapinga me te tiaki pinepine. Nō reira, ko te haumi tuatahi ki te papa kōhatu ka hua ake he penapena nui mō te wā roa.
Hei tāpiritanga, he kōwhiringa pai mō te taiao te karāhe. Nā ōna kai māori me te mea he pūtake tauwhiro tōna, he mea tino pai mō ngā kamupene e hiahia ana ki te whakaiti i ō rātou tapuwae waro. He rite tēnei ki te ia o ngā mahi hanga pai mō te taiao e whakarei ake ana i te ingoa o te kamupene, e kukume ana hoki i ngā kaihoko e aro nui ana ki te taiao.
Hei whakamutunga, ko te whai huatanga o te whakamahi i te karāhe i roto i te hanga PCB e whakaatuhia ana i roto i tōna pumau wera, tōna roa me ngā painga taiao. I a te umanga e rapu tonu ana i ngā otinga auaha, ka tū te karāhe hei kōwhiringa whai hua e kore e whakapai ake i te kounga hua anake engari ka whai wāhi hoki ki ngā penapena me te pumau mō te wā roa.
