Kuiswa kwewaya dzeasbestos kunoratidzika sei?
Zviri mukati
Chinyorwa changu pazasi chichataura nezve iyo asbestos waya insulated waya inotaridzika uye inopa mazano anobatsira.
Asbestos wire insulation yaive sarudzo yakakurumbira yekuvharisa waya yemagetsi muma20s.th zana, asi kugadzirwa kwakamiswa nekuda kwekuwanda kwehutano nekuchengetedza kunetseka.
Nehurombo, kuongorora kwekuona chete hakuna kukwana kuona asbestos waya yekuvharisa. Asbestos fibers idiki zvakanyanya и ndizvo kwete panen kunhuwa. Unoda kuziva kuti iwaya rudzii, yakaiswa nguvai uye yaishandiswa kupi ita fungidziro yakadzidza nezve mukana wekuti iyo insulation ine asbestos. Ongororo yeasbestos inosimbisa kuti iripo here kana kuti kwete.
Ini ndichakuratidza zvekutarisira, asi chekutanga ndinokupa muchidimbu mamiriro ekuti nei kusarudza kuvharirwa kwewaya dzeasbestos kwakakosha.

Asbestos kushandiswa
Asbestos yaishandiswa zvakanyanya kuisa waya dzemagetsi muNorth America kubva munenge muna 1920 kusvika 1988. Yakashandiswa kune yayo inobatsira zvinhu zvekupisa uye kudzivirira moto, magetsi uye acoustic insulation, kusimba kwese, kusimba kwakanyanya, uye asidi kuramba. Kana ichinyanya kushandiswa kuvharisa waya yemagetsi, chimiro chesimbi chakaderera chave chichizivikanwa mune dzimwe nzvimbo dzekugara. Zvikasadaro, yainyanya kushandiswa munzvimbo dzine tembiricha yakanyanya.
Kushushikana pamusoro pekushandiswa kweasbestos kwakatanga kusimudzwa zviri pamutemo muToxic Substances Control Act ya1976 uye Asbestos Emergency Response Act ya1987. Kunyange zvazvo US Environmental Protection Agency yakaedza kurambidza zvinhu zvakawanda zveasbestos muna 1989, migodhi yeasbestos muUS yakaguma muna 2002 uye ichiri kutengeswa munyika.
Ngozi dzeasbestos insulation
Asbestos wire insulation injodzi yehutano, kunyanya kana waya yakasakara kana kukuvara, kana iri munzvimbo yakabatikana yeimba. Kugara kuratidzwa kumhepo yeasbestos fiber particles inogona kuungana mumapapu tishu uye kukonzera zvirwere zvakasiyana-siyana, kusanganisira kenza yemapapu, asbestosis uye mesothelioma. Kazhinji zviratidzo hazvioneki kusvikira makore akawanda gare gare.
Asbestos yave kuzivikanwa secarcinogen, saka vemagetsi havachaishandisa uye vanotsvaga kuibvisa kana kuitsiva. Kana uri kutamira kune imwe imba yekare, unofanira kutarisa kuvharwa kwewaya kweasbestos.
Nzira yekuziva sei asbestos insulated wiring
Kuti ubatsire kuona asbestos-insulated wiring, zvibvunze mibvunzo mina:
- Chii chiri chimiro chewaya?
- Chii ichi waya?
- Wiring yakaitwa riini?
- Wiring iripi?
Chii chiri chimiro chewaya?
Kana waya, sezvaunofungidzira, inogona kunge iine asbestos insulation mune yakakuvadzwa mamiriro, iwe unofanirwa kuitsiva. Inofanira kubviswa kunyange isiri kushandiswa, asi iri muimba inogarwa nevanhu. Tarisa zviratidzo zvekuchekwa, mamiriro ekunze, kutsemuka, nezvimwewo. Kana iyo insulation ikaputsika kana kudonha nyore, inogona kuve nengozi kunyangwe iine asbestos kana kwete.
Rudzi rudzii rwewaya iyi?
Mhando ye wiring inogona kutaura kana iyo insulation ine asbestos. Kune mhando dzakawanda dzewaya dzine asbestos insulation (ona tafura).
| chikamu | Tora | Tsanangudzo (Waya ne…) |
| Asbestos Insulated Wire (Kirasi 460-12) | A | asbestos insulation |
| AA | asbestos insulation uye asbestos braid | |
| AI | inregnated asbestos insulation | |
| PANE | asbestos impregnated insulation uye asbestos braid | |
| Asbolaked jira waya (kirasi 460-13) | AVA | asbestos insulation yakabatanidzwa nemucheka wevarnished uye asbestos braid |
| AVB | asbestos insulation yakamisikidzwa nemucheka wevarnish uye inodzivirira moto yekotoni braid | |
| AVL | asbestos insulation yakaiswa nemucheka wevarnished uye lead coating | |
| Zvimwe | AF | asbestosi inodzivirira kupisa inosimbisa waya |
| AVC | asbestos insulation yakabatanidzwa netambo yezvombo |
Rudzi rwekuvharisa wiring inonyanya kunetseka inonzi vermiculite, inotengeswa pasi pezita rezita reZonolite. Vermiculite inzvimbo inowanzoitika yemaminerari, asi iyo huru kubva kwayakawanikwa (mugodhi muMontana) yakaita kuti yakasvibiswa. Inoratidzika semica uye ine zvikero zvesirivha.
Kana ukawana rudzi urwu rwekudzivirira waya mumba mako, unofanirwa kufonera nyanzvi kuti iongororwe. Mamwe mabhureki ewaya insulation ane asbestos anosanganisira Gold Bond, Hi-Temp, Hy-Temp, uye Super 66.
Imwe mhando yeasbestos wire insulation yaive mold yekupfapfaidza yaigadzira makore ehupfu mumhepo. Zvingave zvakachengeteka chete kana insulation yakanyatsovharwa mushure mekupfapfaidza. Mitemo iripo kazhinji inobvumira kusapfuura 1% asbestos kuti ishandiswe mukupfapfaidza insulation uye bhitumini kana resin binders.
Wiring yakaitwa riini?
Wiring mumba mako pamwe yakaiswa pakatanga kuvakwa imba. Pamusoro pekutsvaga izvi, unofanirwa kuziva kuti waya yeasbestos yakatanga kushandiswa riini munharaunda yako kana nyika uye payakamiswa. Ndepapi papi mutemo wako wemunharaunda kana wenyika wakarambidza kushandiswa kwewaya yeasbestos?
Semutemo, kuUSA izvi zvinoreva nguva iri pakati pa1920 na1988. Dzimba dzakavakwa mushure megore rino dzinogona kunge dzichine asbestos, asi kana imba yako yakavakwa gore ra1990 risati rasvika, kunyanya pakati pemakore ekuma1930 kusvika kuma1950, pane mukana wakakura wekuti kuvharwa kwewaya kuchava asbestos. MuEurope, gore rekugurwa raive rakapoteredza 2000, uye pasi rose, waya yeasbestos ichiri kushandiswa kunyangwe WHO ichidaidzira kurambidzwa kubva 2005.
Wiring iripi?
Izvo zvinodzivirira kupisa zvimiro zveasbestos-insulated wiring zvinoita kuti zvive zvakanaka kumakamuri pasi pekupisa kwakanyanya. Nekudaro, mukana wekuisa waya neasbestos wakakwira kana mudziyo uri, semuenzaniso, simbi yekare, toaster, chitofu chinobatidza kana mwenje wemwenje, kana kana wiring iri padhuze nemudziyo wekupisa senge heater yemagetsi kana bhailer.
Zvisinei, "loose-fill" type asbestos wire insulation yaishandiswawo zvakanyanya kune dzimwe nzvimbo senge attics, mukati memadziro, nedzimwe nzvimbo dzisina maburi. Yaiva nekakupfava. Kana iwe uchifungidzira kuti asbestos wire insulation muattic yako, iwe unofanirwa kugara kure nayo, usachengete zvinhu ipapo, uye fonera nyanzvi kuti ibvise asbestos.
Rudzi rwainyanya kuzivikanwa rweasbestos insulation raiva mapuranga kana kuti zvidhinha zvakanamirwa kumadziro kuviga waya. Iwo akagadzirwa neasibestosi yakachena uye ane njodzi, kunyanya kana ukaona machipisi kana kucheka paari. Asbestos insulation boards kuseri kwe wiring kunogona kunetsa kubvisa.
Asbestos test
Iwe unogona kufungidzira kuti waya yakavharwa neasbestos, asi bvunzo yeasbestos ichadikanwa kusimbisa izvi. Izvi zvinosanganisira kutora matanho ekuchengetedza njodzi dzinogona kuita chepfu, uye kuchera kana kucheka kutora sampuli yekuongorora kusingaoneki. Sezvo ichi chisiri chinhu chinogona kuitwa nemuridzi wemba, unofanirwa kufonera nyanzvi yekubvisa asbestos. Encapsulation inogona kukurudzirwa pane kubvisa zvachose asbestos wire insulation, zvichienderana nemamiriro ezvinhu.
Tarisa zvimwe zvezvinyorwa zvedu pazasi.
