He aha ngā pouaka hiri (paraihe/paraihe hinu/pāpura) e pai ana mō ngā pou araihau?

Te mārama ki te Kōwae o ngā Pouaka Hiri i ngā Pūnaha Arāhau Whaitua

Ko ngā rākau whakamānawa e tāwhai ana i ngā pou whakamānawa iti nei hei tiaki i ngā raru hiko. Ina he nui ake te hiko e rere mai ana, ko ngā taputapu nei ka whakamutua te hiko i mua i te whara e pā atu ana. He mea nui rawa tēnei, nā te kore o ngā taputapu nei ka kitea e mātou he nui ake ngā ahi me ngā taputapu kua whara. Tirohia ngā tau: ko ngā raru hiko e utu ana i ngā tāone i te $1.3 piriona ia tau e ai ki ngā raraunga NFPA mai i te tau 2023. Ko te take i reira nei ka tāwhaihia ēnei pou whakamānawa hou ki te kore noa atu rātou i ngā rākau whakamānawa engari ki ētahi atu taputapu haumaru hoki. Kei te hiahia ngā tāone kia pai tonu te mahi a ō rātou rākau whakamānawa ia pō, ā, kia tiakina hoki ngā tāngata e haere haere ana i te pō mai i ngā raru hiko.

Te Tikanga o te Pūtea Rākau Whakamānawa ki te Haumaru Hiko mo ngā Pou Whakamānawa Rākau

Ko ngā pouaka hiriwa e whai ana i ērā hiriwa itiiti ki roto e noho ana hei wāhi ngoikera ki te whakarite i te tūmata o te hiko. Ki te tīmata haere te nui o te hiko e rere ana, ka tanu ngā hiriwa, ka arantia tēnei te ara katoa ka mutu te hiko. He raweke tēnei. Ko te take tino nui o te whakaritenga kia tiakina tēnei ngā taputapu me ngā tāngata kei te tata. Ka kitea e tātou tēnei tiaki e mahi ana i ngā wāhi pērā i ngā huarahi maruihe, i ngā hōtaka hokohoko kei reira hoki ngā rākau mārama kia kaua ngā tāngata e hinga, kia āhua haumaru ai te haere i te pō.

Ngā Puka Hiko Matua o ngā Pōro Rākau Mārama me te Whakauru ki ngā Pouaka Hiriwa

Ko te mātātoko hiko o te pōro rākau mārama e toru ngā wāhanga matua e herea ana:

• Ngā wira tata ki te whare pūhiko : Whakapakia te hiko ki te pou
• Ngā kaitiaki ara : Tuku atu anō hoki i te tātenga o te hiko
• Te pātene mutu matua : Whakaaetia te mutu ake i te hiko mō te tiaki

Kia rite ki ngā aratohu haumaru hiko, ko ngā pouaka hiko e mahi tahi ana me ngā kaupapa e whakarato atu ana i te whakamarutanga paparua. Ko te whakauru i a ratou ka whakapau moni i te Tuhinga 410 o te Tiriti Hiko o Amerika, e whakaae ana i ngā wehenga hiko ki roto i te 50 ōku (feet) o ia pou kia taea ai te tāwhai i ngā ngoikera me te tūhono haumaru.

Te Whānui i waenganui i te Konumohe, te Paraihe, me ngā Pouaka Hiko Paraihe

Pouaka Hiko Konumohe: Ngā Kaha me ngā Tekeke ki ngā Taiao Waho

Ko ngā pouaka hiko nui he taraiwa noa rānei, he taraiwa hiko hoki nui te whakaratonga i te ārai i ngā whara, nō reira ka pai ai ki ngā tāone kei hea ngā tūraru ake, ākene pea ngā whara. Engari, kei te pīroiroi te take i te tata ki ngā takutai, i te kaha ake o te parurenga o te hukapapa e whakarahi ai i te āpōpō. E āta whakaatu ana tētahi raraunga hou a NEMA, ko te āpōpō e whā ngā wā kua pōuri ake te tere i te wāhi papaku. Ki te whawhai i tēnei raru, ko te maha o ngā kaiwhakauru e whiriwhiri ana ki te whakakī atu i te pātītī ki ēnei pouaka. Ko te whakakī e āpōpō ai i te rēwana e whakapono ana i te pouaka e whai tikangia ana i te wāhi e 15 ki te 20 tau i mua i te hiahia ki te whakakapi. Ka tūhono tātou ki te utu hoki i te rahi o te moni, e whakapaua ana i te utu o ngā rawa kei te 25 ki te 30 ōrau.

Engari kei te tautohuatia tētahi take ina whakamahia ngā taputapu mō ngā wā roa ki waho. Ko ngā wāhanga plastic e noho tūria ana ki te rā e pakaru whakamua ana tere ake i ēnei e noho ana ki ngā wāhi hāpara. Ko ngā whakaahua mai i te ao e whakaatu ana kei te pakaru te āhua toru neke atu te tere ki ngā wāhi e tū ana ki te rā tino. Ka luck tēnei, ko ngā kaihanga kei te tīmata ki te whakauru i ngā kaiwhakapai UV ki ā rātou hua. Āwhina ana ēnei taupua ki te whakapai ake i te roa o te whakamahi, e toru tau te roa o te whakamahi mai i te waru ki te tekau mā whā tau tonu atu anō ia rā tonu te rā e noho ana.
