Me pēhea te whiriwhiri i ngā rauemi ātete ahi tika: He aratohu hangarau mō ngā kaihanga me ngā kaihoahoa

 

Te whiriwhiri tika nga rauemi aukati ahi He whakatau nui tēnei i roto i te hoahoa hua, te hanga, me te hanga e whakataurite ana i te haumaru, te mahi, te utu, me te tutuki i ngā ture. Ka whakaratohia e tēnei tuhinga hangarau he anga whānui mō te aromatawai me te whiriwhiri i ngā rauemi ātete ahi i runga i ngā whakaritenga tono, ngā mātāpono pūtaiao ahi, ngā āhuatanga rauemi, me ngā paerewa ahumahi. Ka tirohia e mātou ngā akomanga rauemi, ngā tikanga whakamātautau, me ngā tawhā mahi hei whakatū i tētahi tukanga whiriwhiri pūnaha mō ngā tono hangarau.

 

Te Wero Ahi i roto i ngā Rauemi Hou

Kua piki haere te uaua o te haumaru ahi nā te nui haere o ngā rauemi hangai i roto i tō tātou taiao hanga, ngā pūnaha kawe waka, me ngā hua kaihoko. E ai ki te National Fire Protection Association, ka aro atu ngā tari ahi o Amerika ki te ahi i ia 24 hēkona, ā, neke atu i te $14.8 piriona te kino o ngā rawa i ia tau. Ko te whiriwhiri i ngā rauemi ārai ahi e tika ana he rautaki matua hei whakaiti i ēnei mate me te tiaki i ngā oranga.

He mea hanga ngā rauemi ātete ahi hei ātete i te mura, hei puhoi i te horapa o te mura, hei whakaiti i te tukunga wera, hei whakaiti hoki i te whakaputanga paowa ina pāngia e te ahi. He rerekē ki ngā rauemi kore-mura pērā i te maitai, i te raima rānei, ko te nuinga o ngā rauemi ātete ahi he papa mura kua rongoatia, kua hangaia rānei ki ngā tāpiringa hei whakarerekē i te whanonga mura. Me mārama te tukanga whiriwhiri ki te pūtaiao rauemi me ngā āhuatanga ahi e pā ana ki te tono e hiahiatia ana.

Te Tirohanga a meake nei me te Whakamutunga

Tuhinga o mua nga rauemi aukati ahi kei te whanake haere ki ngā pūnaha e mau tonu ana, e maha ana ngā mahi, ā, he tino tika te hanga mō ngā tūmomo riri motuhake. Ko te rauemi ārai ahi tino pai o te heke mai ka penei pea:

1. Whakaratohia te haumaru ahi hei āhuatanga ā-roto, kaua hei tāpiritanga
2. Kia mau tonu, kia whakarei ake rānei i ngā mahi matua o ngā rauemi
3. He iti noa te pānga ki te taiao puta noa i tōna huringa ora
4. Kia whai hua te utu mō te whakamahinga whānui
5. Tukua kia ngāwari te hangarua, te whakakore rānei

He wero maha tonu te whiriwhiri i te rauemi ārai ahi tika e hiahia ana kia mahi tahi ngā kaimātai matū, ngā miihini, ngā kaiwhakahaere, me ngā tohunga haumaru ahi. Mā te whakamahi i te huarahi pūnaha kua whakarārangihia i roto i tēnei tuhinga—tīmata mai i te whakamāramatanga pakari o ngā whakaritenga, te aromatawai i ngā rauemi ki ngā paearu whānui, me te whakamana i te mahi mā te whakamātautau tika—ka taea e ngā kaihoahoa te whakatau whai whakaaro hei whakapai ake i te haumaru, te mahi, me te uara.

Ehara i te mea ko te rauemi tino tika ko te mea he ātete mura teitei rawa, engari ko te mea e tutuki ana i te taumata haumaru ahi e hiahiatia ana, me te whakatutuki i ngā whakaritenga tono katoa. I roto i tētahi ao e piki haere ana te ture me te aro nui ki te haumaru, ko te whiriwhiri rauemi whakaaro nui he mea nui ki te hangarau me te tikanga matatika mō te hoahoa me te hanga kawenga.
