He aha te Pūwhakapakari Arahiko Korehau (VCB)?

He taputapu nui te pūwehe hiko korehau e whakamahia ana hei whakahaere me te tiaki i te iahiko i roto i ngā pūnaha hiko. Ka mahi mā te whakakore, te whakatuwhera rānei i tētahi hiko i raro i ngā āhuatanga rerekē, pēnei i te poto o te hiko, te taumaha rawa rānei. Kāore i rite ki ngā pūwehe hiko tuku iho, ka whakamahia e ngā VCB te korehau hei tinei i te pewa i hangaia i te wā o te whakakorenga hiko. Mā tēnei tikanga matatau ka whakarite kia pono, kia whai hua hoki te tiaki hiko, ka waiho te VCB hei whiringa rongonui puta noa i ngā ahumahi rerekē.

Haunga ōna āhuatanga haumaru tino pai, he maha ngā painga o te VCB. Tuatahi, ka taea e rātou te tinei i te pewa i roto i te korehau me te kore e hiahiatia he rauemi ārai atu, ka taea ai te hanga i tētahi hoahoa kiato e hiahia ana kia iti te tiaki. Hei tāpiri, ko tō rātou wā urupare tere (e inehia ana i roto i ngā maikorohekona) ka whakarite i te tiaki hapa pumau, ka tiaki i ngā taputapu hiko utu nui. E mārama ana he roa ake te ora ratonga o te VCB i ngā kaiwawao hiko tuku iho, kāore he hau kino pēnei i te SF6, ā, he pai ake te taiao.

Nā te maha o ngā whakamahinga o ngā pūwā hiko korehau, he pai mō ngā momo mahi maha. Ahakoa i roto i ngā teihana hiko, i ngā papa ahumahi, i ngā whare noho rānei, ka tutuki i ngā VCB te whānuitanga o ngā whakaritenga o te ngaohiko me te iahiko. Mai i te tiaki i ngā whakawhiti hiko me ngā whakaputa hiko ki te ārai i ngā ahi hiko, he mea nui te mahi a ēnei pūwā hiko ki te pupuri i te pono me te haumaru o ngā pūnaha hiko nui.

Hei whakarāpopototanga, he wāhanga nui ngā pūwā hiko korehau o ngā hanganga hiko o ēnei rā. Nā te kaha ki te tiaki i ngā pūnaha hiko mai i ngā hapa, me te hoahoa kiato me ngā āhuatanga taiao, koinei te whiringa tuatahi i roto i ngā ahumahi rerekē. I te haere tonu o te whanaketanga o te hangarau, kāore e kore ka whai wāhi nui ngā VCB ki te whakarite i te haumaru me te whai huatanga o ngā pūnaha hiko e whanake haere ana.
