1. Kōwhiringa tika:
I runga anō i ngā āhuatanga o te taputapu me ngā hua i hangaia, ka tīpakohia te paraikete tika.
2. Whakatikahia te mokowā o te roera kia tika ai te rārangi paerewa, kia kaua e piko, kia kore ai hoki e takai.
3. Kia mōhio ki ngā taha pai me ngā taha kino
Nā te rerekētanga o ngā tikanga whakatakotoranga, ka wehea ngā paraikete e ngā taha o mua me muri, kei te taha o mua o ngā paraikete a te kamupene te kupu "mua", ā, me anga te taha o mua e te pere ki waho, kia rite ki te ahunga o te mahi a te mīhini pepa, ā, me taurite te kukū o te paraikete hei ārai i te kukū nui rawa, te wetekina rawa rānei.
Ko ngā paraikete hanga pepa ka horoia, ka pēhia ki te wai hopi 3-5% alkali mō ngā hāora e rua, ā, he pai ake te wai mahana i te pāmahana tata ki te 60 °C. I muri i te hanga pepa angiangi, ka whakamakukuhia te paraikete hou ki te wai, ā, me 2-4 hāora te wā whakangawari. Ko te wā whakangawari o te paraikete tāera asbestos me 1-2 hāora i muri i te whakamakuku ki te wai ma. Kāore e whakaaetia kia maroke te paraikete me te kore e mākū ki te wai.
4. Ina kei runga te paraikete i te mīhini, karohia te paru hinu o te pane o te kakau e whakapoke i te whāriki.
5. He nui ake te muka matū o te paraikete ngira, ā, me karo te horoi waikawa kukū.
6. He nui te wai o te paraikete werohia ki te ngira, ā, i te wā e whakairohia ana, ka taea te whakanui ake i te pēhanga o te raina momi korehau, te raina roera whakaputa rānei, ā, he maripi koko waikeri kei te roera pehanga ki raro hei tuku i te wai mai i ngā taha e rua, hei whakaiti hoki i te makuku o te whārangi.
7. Whakapirihia te muka me te whakakī ki te penupenu, he māmā ki te ārai i te paraikete, ka puta he whakairo, ka taea te horoi mā te rehu wai i ngā taha e rua, ka whakanui ake i te pēhanga horoi, he pai ake te huri me te horoi i muri i te tāke wai wera o te 45 nekehanga Celsius. Kaua e parai i ngā paraikete ki te paraihe mārō i te wā e horoi ana.
8. He papatahi, he matotoru te paraikete werohia ki te ngira, kāore e ngāwari ki te whakapiko, ā, kaua e tino pūmau te whakatuwhera. Ki te whānui rawa te paraikete, kāore e taea te kume, whakamahia he rino tūhono hiko hei whakatuwhera i te taha, tapahia rānei te taha ki te kutikuti, kātahi ka whakamahia te rino tūhono hiko hei hiri i te taha.
9. Ētahi atu tohutohu me ngā whakaritenga
9.1 Me rongoa motuhake te paraikete mai i ngā rauemi matū me ētahi atu rauemi hei karo i te kino o te waikura ki te paraikete.
9.2 Me maroke, kia whai hauhautanga hoki te wāhi e rongoa ai te paraikete, ā, me whakatakoto kia papatahi, kaua e tū tika, kia kore ai e wetekina, e whakawhāitihia rānei tetahi ki tetahi.
9.3 Kaua te paraikete e rongoatia mō te wā roa rawa, nā ngā āhuatanga o ngā muka matū, he nui te pānga o te rokiroki mō te wā roa ki te panonitanga o te rahi o te paraikete.
