1. Kia mārama ki te mahi ate huame te wehewehe mēnā he paitini, kāore rānei. Ko te nuinga o tēnei e whakawhirinaki ana ki te rauemi i hangaia ai te kirihou, me te mea kei roto ngā mea whakapūmau kirihou, ngā mea whakapūmau, me ētahi atu. Ko te nuinga o ngā pēke kai kirihou, ngā pounamu miraka, ngā peere, ngā pounamu wai, me ētahi atu e hokona ana i te mākete he kirihou polyethylene te nuinga, he mea pania ki te hinu ina pā, ā, he rite te mata ki te paparanga ware pi, he ngāwari ki te tahu, he mura kōwhai me te ware pi e maturuturu ana. He kakara paraffin tēnei kirihou, kāore he paitini. Ko ngā pēke kirihou, ngā ipu rānei mō ngā takai ahumahi he mea hanga ki te polyvinyl chloride, me ngā mea whakapūmau tote kei roto te mata i tāpirihia ki roto. Ina pāngia e te ringa, he piri tēnei kirihou, ā, kāore e ngāwari ki te tahu. Ka tineia tonutia i muri i te wehenga atu i te ahi. He kakariki te mura, ā, he taumaha te taumaha. He paitini tēnei kirihou.
2. Kaua e whakamahiangā hua kirihouki te tākai hinu, winika me te waina i ngā wā e pai ai. Ahakoa ngā peere mā, mārama hoki e hokona ana i te mākete, kāore e pai mō te penapena roa i te hinu me te winika, ki te kore ka pupuhi ngāwari te kirihou, ā, ka waikura te hinu, ka puta he matū kino ki te tinana tangata; me aro hoki koe ki te waina, kaua e roa rawa te wā, ki te roa rawa ka whakaiti i te kakara me te nui o te waina.
He mea nui kia mōhiotia kia kaua e whakamahia ngā peere PVC paitini hei pupuri hinu, winika, waina, me ētahi atu, ki te kore ka poke te hinu, te winika me te waina. Ka mamae pea, ka whakapairuaki, ka mate pāwera te kiri, me ētahi atu, ā, ka kino pea te hinu wheua me te ate i ngā wā tino kino. Hei tāpiri, me tūpato hoki kia kaua e whakamahia ngā oko hei tākai hinu, penehīni, tīhiera, toluene, ether, me ētahi atu, nā te mea he ngāwari te whakangawari me te pupuhi i te kirihou tae noa ki te pakaru me te kino, ka puta he hua ohorere.
3. Kia aro ki te tiaki me te ārai i te koroheketanga. Ina whakamahi te tangata i ngā hua kirihou, he maha ngā wā ka tūtaki rātou ki ngā āhuatanga pēnei i te whakapakeke, te pakarukaru, te rerekētanga o te tae, te ngatata me te hekenga o te mahi, arā, te koroheketanga kirihou. Hei whakaoti i te raruraru koroheketanga, he maha ngā wā ka tāpirihia e te tangata ētahi antioxidants ki ngā kirihou hei whakaroa i te tere o te koroheketanga. Inaa, kāore tēnei e whakaoti i te raruraru. Kia roa ai ngā hua kirihou, ko te mea nui ko te whakamahi tika, kaua e tukua kia pā ki te rā, kaua e ua, kaua e tunua ki te ahi, kaua hoki e whakamahana, kaua hoki e pā pinepine ki te wai, ki te hinu rānei.
4. Kaua e tahuna te mea kua makahiangā hua kirihouE ai ki te kōrero i mua ake nei, ehara i te mea ngāwari te tahu i ngā kirihou paitini, nā te mea ka puta he paoa pango, he haunga me ngā hau paitini ina tahuna, he mea kino ki te taiao me te tinana tangata; ā, ka poke anō hoki te taiao i te tahunga kore-paitini, ā, ka pā ki te hauora o te tangata. Ka taea hoki e ia te whakaputa i ngā mumura maha.
