Mō te hanganga matū, ko te whakahaere tino pakari i ngā here matū kino, ngā tukunga matū waro mimiti (VOC) me te kounga o ngā rauemi mata e whakarite ana i te hauora me te haumaru o ngā kaiwhakamahi. Ko te whānui me te tino pakari o ēnei paerewa haumaru ka whakarato i te tiakitanga whānui ki ngā kaihoko, ā, ka whakarite i te haumaru o ngā papa hope silicone i te wā e whakamahia ana.
5.3 Te pakari o te tirotiro kounga
He hononga nui te tirotiro kounga o ngā papa hope silicone hei whakarite kia tutuki ngā hua i ngā paerewa tiaki taiao me te haumaru. Kei roto i te tukanga tirotiro tiaki taiao te tirotiro rauemi mata, te aroturuki i ngā tukanga whakaputa, te tirotiro hua kua oti, te tiwhikete me te tapanga, me ētahi atu. Mā roto i ngā paparanga tirotiro, ka whakarite kia kore te hua e poke i ngā matū kino i te wā o te tukanga whakaputa, ā, i te mutunga ka tutuki i ngā paerewa tiaki taiao tino pakari. Ko te whakamātautau mahi haumaru e kapi ana i te whakamātautau mahi ā-tinana me te whakamātautau hanganga matū. Mā roto i ngā tikanga whakamātautau tika me ngā paerewa whakamātautau tino pakari, ka arotakehia whānuitia ngā tohu mahi o te hua hei whakarite i te haumaru me te pono o te hua i te whakamahinga tūturu. Mā ēnei tukanga me ngā tikanga tirotiro kounga tino pakari ka whakawhiwhia ki ngā kaihoko he taurangi hua kounga pono.
5.4 Te Tūnga o te Mākete me te Tirohanga a te Kaihoko
He rerekētanga nui kei roto i ngā paerewa whakatinanatanga o ngā papa hope silicone o ngā waitohu rerekē kei te mākete. Ko ētahi waitohu rongonui e tino whai ana i ngā paerewa teitei i te kāinga me tāwāhi, ā, he iti rawa te taumata o ā rātou hua i runga i te taumata e pā ana ki te ihirangi matū kino me ngā tukunga VOC, ko ētahi waitohu iti, ko ngā hua iti rānei e tutuki ana i ngā paerewa iti rawa o te kāinga, e hipa ana rānei i ngā paerewa. He maha ngā wā ka pāngia ngā kaihoko e ngā hē whakaaro hinengaro i te wā e hoko ana, pērā i ngā hē whakaaro utu me te kounga, ngā hē whakaaro tohu tiwhikete, me ngā hē whakaaro mahi me te haumaru. Mā ēnei hē whakaaro ka hoko pea ngā kaihoko i ngā hua kāore e tutuki i ngā paerewa, ā, ka pā ki te haumaru. Nō reira, i te wā e hoko ana i ngā papa hope silicone, me whai whakaaro whānui ngā kaihoko ki ngā paerewa tiaki taiao me te haumaru o ngā hua, ā, me whiriwhiri i ngā waitohu me ngā hua e tutuki ana i ngā paerewa tino pakari hei whakarite i te hauora me te haumaru o rātou anō me ō rātou whānau.
