Te Wetewete i te Kaha Whakaoho Nui: Ngā Tohutohu Matua mō te Mahi Tino Pai

Ko te whakapakari i te kaha o te haruru o ngā ipu hī ika tino kaha me whai rautaki ki ngā tikanga whakahaere me te tiaki taputapu. Anei me pēhea te whakanui ake i te whai huatanga o te pānga:

Tuatahi, he mea nui te whakarerekē i te tere hiki o te aho wiri. Mā te whakanui ake i te tere ki runga ka nui ake te kaha pīngore i roto i te aho wiri, ka nui ake te kaha o te kawenga hihiri ina tukuna. He mea nui tēnei kaha mō te whakaputa i te kaha wiri whai hua ki ngā taputapu wiri kua mau.

Tuarua, ko te arotau i te whirihoranga o te aho wiri te mea nui. Mā te tāpiri i te taumaha tika—pērā i ngā kara wiri—ki runga ake i te ipu ka nui ake te penapena pūngao i te wā e hiki ana. Mō ngā hua pai ake, mā te hono i te ipu me te whakanui ipu i roto i te huihuinga taputapu ka hangaia he papatipu whakaemi, ka whakanui ake i te kaha e tukuna ana ki te ika kua mau.

He mea nui anō hoki te pupuri i te kounga o te poka wai. Mā te poka wai maeneene, pumau ka whakaitihia te waku, ka taea ai te tuku i te kaha wiri me te kore e ngaro te pūngao. Mā te whakatikatika i te poka wai i mua i te mahi ka tino whakapai ake i te whai huatanga o te kaha.

He mea nui anō hoki ngā tikanga whakahaere pai rawa atu: tīmata me te iti o te taumahatanga, kātahi ka whakanuia haeretia kia kore ai e pakaru ngā taputapu. I muri i te mahi, mā te horoi pai i ngā wāhanga waipēhi (pēnei i te kōhao i waenganui i te paipa hiku me te tinana pēhanga), te whakakī hinu auau, me ngā whakamātautau pēhanga (hei tauira, 30 MPa mō te pono o te hiri) ka whakarite kia mau tonu te mahi.

Mā te whakauru i ēnei tikanga, ka taea e ngā kaiwhakahaere te iriti i te kaha wiri tino pai, ka whakarei ake i te whai huatanga o te whakaora i roto i ngā horopaki keri uaua.
