Ko te whakamahinga o te pepa rapa asbestos i roto i te umanga hiri takirere he penei ngā painga:

Utu iti: Ki te whakaritea ki ētahi atu rauemi hiri mahi-tiketike, he iti ake te utu o te pepa rapa asbestos.

Ātete matū: He pai te ātete waikura o te pepa rapa asbestos mō ētahi momo rauemi me ngā āhuatanga matū ngawari, ka taea te whakatutuki i ngā hiahia o ngā tikanga mahi whānui.

Te tiaki ngāwari: Nā te mea he ngāwari te tukatuka me te whakakapi i te pepa rapa asbestos, he watea ake mō te tiaki i te takirere.

Ko te raru nui o te pepa rapa asbestos ko te mea ahakoa kua tāpirihia te rapa me ētahi whakakī ki te rauemi gasket, kāore tonu e taea te whakakī katoa i ngā pūwero iti e hono ana, ā, he iti noa te urunga. Nō reira, i roto i te reo poke nui, ahakoa kāore i te teitei te pēhanga me te pāmahana, kāore e taea te whakamahi. Ina whakamahia ki ētahi reo hinu pāmahana teitei, i te nuinga o te wā i te wā whakamahinga o muri mai, nā te waro o te rapa me te whakakī, ka heke te kaha, ka wetekina te rauemi, ā, ka uru ki te atanga me roto i te gasket, ā, ka puta te kō me te paowa. Hei tāpiri, he ngāwari te here o te pepa rapa asbestos ki te mata hiri flange i te pāmahana teitei, ka nui te raruraru ki te whakakapinga o te gasket.

I te āhua wera, ko te pēhanga o te gasket i roto i ngā momo pāpāho e whakawhirinaki ana ki te tere pupuri kaha o te rauemi gasket. Kei roto i te rauemi muka asbestos te wai tioata me te wai mimiti. I te 110℃, kua rewa te 2/3 o te wai mimiti i waenganui i ngā muka, ā, kua heke te kaha kume o ngā muka mā te 10%. I te 368℃, ka rewa katoa te wai mimiti, ā, kua heke te kaha kume o te muka mā te 20%. Neke atu i te 500℃, ka tīmata te rewa o te wai tioata, ā, ka iti iho te kaha.

Kei roto i te pepa rapa asbestos ngā katote hauota me te whanariki, he ngāwari ki te hanga i ngā pūtau konukōre waikura me ngā flange whakarewa i muri i te mimiti wai, inā koa he maha ngā wā he nui ake te ihirangi whanariki o te pepa rapa asbestos ātete-hinu i tērā o te pepa rapa asbestos noa, nō reira kāore e pai mō te whakamahi i roto i ngā pāpāho kore-hinu. Ka pupuhi ngā hiri i roto i ngā pāpāho hinu me te whakarewa, engari i roto i tētahi whānuitanga, kāore he pānga ki te mahi hiri.

Heoi, he mea nui kia mōhiotia kua tautuhia te asbestos hei matū morearea, ā, ko te whakamahinga o ngā rau rapa asbestos ka pā he mōrearea ki te hauora me te taiao.
