He wāhanga nui ngā roera rapa i roto i te whānuitanga o ngā rāngai ahumahi, tae atu ki te hanga kakahu, te tā, ngā taputapu aunoa tari, me te tukatuka rauemi. I te wā e hangaia ana ngā roera hou me te huri anō i ngā roera tawhito, ka puta he nui o te puehu rapa pai me ngā matūriki i roto i te tukanga huri. Kāore i rite ki te huri whakarewa, e whakamahia ana ngā wai whakamatao hei pehi i te puehu, ka maroke te mahi a te huri roera rapa, ka taea ai te puehu rapa te marara noa ki te hau e karapoti ana. Ka puta he tūponotanga nui ki te wāhi mahi, he wero tiaki taputapu, me ngā āwangawanga kounga hua. Nō reira, kua noho ngā kaikohi puehu hei pūnaha āwhina nui mō ngā mīhini huri roera rapa, hei hopu, hei tātari, hei whakakore haumaru hoki i te puehu huri.
Te Hiahia o te Kohikohi Puehu
Ehara i te mea he mea whakararuraru noa iho te puehu rapa e puta ana i te wā e huri ana i ngā roera—engari he nui ngā mōrearea mahi me te hauora. He pai, he māmā hoki ngā matūriki puehu rapa, ā, ka taea e rātou te noho ki te rangi mō te wā roa, ka tau ki runga i ngā mata mīhini, ki ngā wāhanga hiko, me ngā hua kua oti. I roto i ngā mira kakahu, ina hurihia ngā roera rapa, ka hurihia anō hoki, ka nui te puehu e kohikohia ana. Ko te roa o te wā e pāngia ana e te puehu rapa ka pāngia e ngā mate manawa, tae atu ki te pneumoconiosis, ka waiho te tiaki hauora o ngā kaimahi hei kaupapa matua mō te whakamahi i te pūnaha kohikohi puehu.
Haunga ngā āwangawanga hauora, ka taea e te puehu rapa kua kohia ki ngā ara o te mīhini huri, ngā aratohu, me ngā taputapu pupuri mahi te whakararu i te tika o te huri me te kounga o te mata. Hei tāpiri, ka mura te puehu rapa; i ngā wāhi kuiti me te nui o te hāora me ngā pūtake mura, ka puta he tūponotanga ahi tūturu i te kohi puehu. Ka whakaitihia ēnei tūponotanga e ngā kaikohi puehu mā te tango tonu i te puehu mai i te pūtake.
Ngā Mātāpono Whakahaere o ngā Pūnaha Kohikohi Puehu
Ko ngā pūnaha kohikohi puehu mō ngā mīhini huri roera rapa e mahi ana i runga i te kaupapa o te tango ā-rohe me te tātari maha-wāhanga. Ko te pūnaha noa he taupoki kohikohi puehu e tū tata ana ki te atanga o te wira huri-te-pūnaha mahi, he pā momi, he pupuhi rānei e hanga ana i te pēhanga kino, he paipa e kawe ana i te hau e kī ana i te puehu, me tētahi, neke atu rānei ngā wāhanga tātari, wehenga rānei.
Ka whakatakotoria te taupoki kohikohi puehu ki te taha o te wāhi huri hei hopu i te puehu i tōna wāhi whakaputa i mua i te marara. Ka whakaputahia e ngā pā hau pehanga teitei te kaha momi e hiahiatia ana hei wikitoria i te ātete o te pūnaha me te kawe i ngā matūriki puehu mā roto i ngā paipa. Kātahi ka haere te rerenga hau kua kohia mā roto i ngā pāpāho tātari—tae atu ki ngā wehewehe āwhiowhio, ngā putea tātari, ngā tātari kātere, tae atu ki ngā horoi mākū—te wāhi e wehea ai ngā matūriki totoka mai i te rerenga hau. Ka whakauruhia pea e ngā pūnaha matatau ngā wāhanga tātari maha hei whakatutuki i ngā tukunga matūriki tata-kore.
Ngā Mahi Matua o ngā Kaikōhikohi Puehu
Ka taea te whakarāpopoto i ngā mahi matua a ngā kaikohi puehu i roto i ngā mahi huri roera rapa penei:
Te Hopu me te Pupuri i te Pūtake: Mā te tango tika i te puehu i te wāhi huri, ka āraihia e ngā kaikohi puehu te horapa whānui o ngā matūriki rapa puta noa i te awheawhe. Mā tēnei ka noho ma te wāhi mahi, ka tiakina hoki ētahi atu mīhini mai i te poke o te puehu.
Te Tiakitanga Kounga Hau: Ka tangohia e ngā pūnaha tātari ngā matūriki hau i mua i te tukunga anō, te paunga rānei o te hau, hei tiaki i te hauora manawa o te kaiwhakahaere, me te whakarite kia tutukihia ngā herenga pānga ki te mahi.
Te Pūmautanga o te Tukanga: Mā te tango tonu i ngā para huri mai i te wāhi mahi, ka āraihia e ngā kaikohi puehu te whakatakotoranga anō o ngā matūriki ki te mata o te roera, ki te kore ka puta he hapa o te mata, ka whakararu rānei i te tika o ngā āhuatanga.
Te Whakaiti i te Mōrearea Ahi: Mā te tango me te penapena pūmau i te puehu rapa mura ka tino whakaiti i te tūponotanga o ngā pahūtanga puehu, ngā ahi rānei.
Te Roa o te Taputapu: Mā te pupuri i ngā wāhanga o te mīhini huri kia kore e puta te puehu rapa whakakoi ka whakaiti i te kakahu o ngā wāhanga e neke ana, ā, ka roa ake hoki ngā wā tiaki.
Ngā Momo Pūnaha Kohikohi Puehu
He maha ngā whirihoranga kohikohi puehu e whakamahia ana i roto i ngā mahi huri roera rapa, ia mea e tika ana mō ngā tauine whakaputa me ngā whakaritenga rerekē. Ka whakamahia e ngā wehewehe āwhiowhio te kaha whakatere hei wehe i ngā matūriki nunui mai i te rerenga hau, ā, he maha ngā wā ka whakamahia hei tātari-mua. Ka whakamahia e ngā kohikohi whare putea, kātere rānei ngā pāpāho tātari papanga, whakapiko rānei hei hopu i ngā matūriki iti, ā, ko ētahi pūnaha ka eke ki te 99%, pai ake rānei te pai o te tātari mō ngā matūriki iti-micron. Ka tukuna e ngā kaihoroi mākū te hau kapi i te puehu mā roto i te wai, ka hopu i ngā matūriki i roto i te wāhanga wai—he huarahi tino whai hua mō ngā puehu piri, ngā puehu hygroscopic rānei. Ka whakakotahi ētahi pūnaha i ngā hangarau maha, pērā i te wehenga-mua āwhiowhio, ā, ka whai muri ko te tātari putea, hei arotau i te mahi puta noa i te whānuitanga o ngā rahi matūriki.
Ngā Whakamahinga Whaihua me ngā Tauira Ahumahi
He whānuitia te whakamahinga o ngā kaikohi puehu puta noa i ngā ahumahi e whakawhirinaki ana ki te huri i ngā roera rapa. I roto i ngā mira miro kakahu, me huri anō i ngā roera rapa i ia wā, ka whakauruhia ngā pūnaha kohikohi puehu motuhake ki ngā mīhini huri roera hei pupuri i ngā taiao mahi ma. I roto i te umanga tā, he mea nui ngā roera rapa tino tika mō te whakawhiti waituhi kounga, ka āwhina ngā kaikohi puehu ki te whakatutuki i ngā whakaritenga whakaoti mata me te tiaki i te hauora o te kaiwhakahaere. Kua whakawhanakehia e ngā kaihanga taputapu tari e huri ana i ngā roera mō ngā mīhini tārua me ngā pūreretā he pūnaha tātari motuhake e toru ngā wāhanga e uru ana ki te kohikohi puehu, te tātari pouaka tātari, me te horoi wai kia kore ai e puta he puehu.
Ko ngā hua kohikohi puehu arumoni i hangaia mō ngā mahi huri roera rapa he āhuatanga pēnei i te kaha mahi tonu mō ngā hāora 24, te kaha momi nui, te kaha rokiroki puehu nui, me te tātari tae atu ki te rahi matūriki tae atu ki te 0.1 micron. Kei roto i ētahi pūnaha he whakaoho pāmahana me ngā pūnaha rehu wai aunoa hei whakaiti i te mōrearea ahi ina nui ake te pāmahana i ngā paepae kua whakaritea.
Whakamutunga
He mea nui te mahi a ngā kaikohi puehu i roto i ngā mahi huri roera rapa, e aro ana ki ngā wero nui o te tiaki hauora o ngā kaimahi, te whakapūmau kounga o ngā tukanga, te tiaki taputapu, me te haumaru ahi. I te mea ka kaha haere ngā ture akuaku ahumahi, ā, ka piki haere tonu ngā whakaritenga kounga whakaputa, ka noho tonu te whakaurunga o ngā pūnaha kohikohi puehu whai hua me ngā mīhini huri roera rapa hei whakaritenga matua mō te mahi hanga kawenga. Ko te whanaketanga tonu o ngā pāpāho tātari whai hua ake, ngā pūnaha whakahaere atamai ake, me ngā hoahoa taputapu kiato ake e kī ana ka whakarei ake i te whai huatanga me te wātea o te hangarau kohikohi puehu i roto i tēnei tono ahumahi nui.
