I roto i te hanga papa porowhita tānga (PCB), he mea nui te tika me te pumau. Ko te moenga karāhe tētahi o ngā wāhanga matua e whakapai ake ana i te mahi a ngā mīhini wero PCB. Ehara i te mea he momo noa te whakamahi i te karāhe i roto i ēnei mīhini; he kōwhiringa rautaki me ngā painga maha.
E mōhiotia ana te karāhe mō tōna pakari me tōna mātotorutanga pai, he mea nui ēnei hei pupuri i te pumau i te wā e werohia ana. Ina whakahaerehia he mīhini wero PCB, ka pāngia e ngā kaha me ngā wiri. Ka mimiti pai ngā moenga mīhini karāhe i ēnei wiri, ka whakaiti i ngā nekehanga ka taea te whakararu i te tukanga wero. Mā tēnei pumau ka whakarite kia tika te tūnga o ngā kōhao wero, he mea nui ki te mahi a te hua PCB whakamutunga.
Hei tāpiritanga, he ātete te moenga karāhe ki te horapa wera. He mea nui tēnei āhuatanga i roto i ngā taiao e piki haere ana te pāmahana. Kāore i rite ki ētahi atu rauemi ka horapa, ka whakawhāiti rānei i ngā huringa pāmahana, ka mau tonu te karāhe i ōna rahi, kia mau tonu ai te mahi mō te wā roa. He mea nui tēnei pumau mō te whakaputanga nui, nā te mea ahakoa he iti noa te rerekētanga ka arahi pea ki ngā raruraru kounga nui.
Hei tāpiritanga, he ngāwari te tiaki me te horoi i te moenga karāhe. Mā tōna mata kore-pūpū ka ārai i te kohikohinga o te puehu me ngā paru ka pā kino ki te mahi a te mīhini. Ehara i te mea ka roa ake te ora o te mīhini i tēnei taumata o te ma, engari ka āwhina hoki ki te whakapai ake i te kounga whānui o ngā PCB e hangaia ana.
Hei whakarāpopototanga, he mea nui te whakauru i tētahi moenga karāhe ki roto i tētahi mīhini wero PCB. Ka whakanui ake te moenga karāhe i te tika me te whai huatanga o te tukanga hanga PCB mā te whakarato i te pumau pai rawa atu, te ātete ki te whakawhānui wera me te ngāwari o te tiaki. Kāore e taea te whakanui i te hiranga o tēnei auahatanga i te mea kei te whanake tonu te ahumahi, ka waiho te karāhe hei rauemi tino nui i roto i te hanga PCB hou.
