Mai gano carbon monoxide ko Mai gano CO na'urar ce da ke gano kasancewar carbon monoxides (CO) gas don hana guba na carbon monoxide. A ƙarshen shekarun 1990s, Laboratories na Underwriters sun canza ma'anar mai gano CO guda ɗaya tare da na'urar sauti zuwa ƙararrawar carbon monoxide (CO). Wannan ya shafi duk ƙararrawar tsaro ta CO da ta hadu da UL 2034; [1] duk da haka ga alamomi masu wucewa da na'urorin tsarin da suka hadu da UL 2075, UL yana nufin waɗannan a matsayin Masu gano carbon monoxide. Yawancin masu gano CO suna amfani da firikwensin tare da ayyanawa, iyakantaccen rayuwa, kuma ba za su yi aiki ba har abada.
CO ba shi da launi, mara ɗanɗano, kuma ba shi da ƙanshi wanda aka samar ta hanyar ƙonewar kayan da ke dauke da carbon. Sau da yawa ana kiransa "mai kisan kai" saboda kusan mutane ba za su iya gano shi ba. A cikin binciken da Underwriters Laboratories suka yi, "kashi sittin cikin dari na Amurkawa ba za su iya gano alamun yiwuwar ɓarkewar CO a cikin gida ba".[2] Matsayi mai girma na CO na iya zama haɗari ga mutane dangane da adadin da ke akwai da tsawon bayyanar. Ƙananan maida hankali na iya zama mai cutarwa a tsawon lokaci yayin da karuwar maida hankali ke buƙatar rage lokutan fallasawa don zama mai cutar.
Wadanda ke zaune a cikin gidajen lantarki ba sa buƙatar masu gano CO sai dai idan akwai garage da aka haɗa tare da mota mara lantarki, ko kuma idan an yi amfani da janareta na ajiya kusa da wuraren zama a lokacin katsewar wutar lantarki.[3]
An tsara masu gano CO don auna matakan CO a tsawon lokaci kuma suna yin ƙararrawa kafin matakan CO masu haɗari su tara a cikin mahalli, suna ba mutane isasshen gargadi don samun iska a yankin ko kuma su kwashe su. Wasu masu ganowa da ke haɗe da tsarin suna faɗakar da sabis na saka idanu wanda zai iya aika ayyukan gaggawa idan ya cancanta.
Duk da yake masu gano CO ba sa aiki a matsayin Masu gano hayaki kuma akasin haka, ana sayar da masu gano hayakin / CO.[4] A cikin gida, wasu tushen CO na yau da kullun sun haɗa da harshen wuta, masu dumama sararin samaniya, masu dumamar ruwa, bututun wuta ko gudu mota ko grill a cikin garage.
Shigarwa
[gyara sashe | gyara masomin]Na'urorin na iya aiki da batir ko AC (tare da ko ba tare da madadin batir ba). Na'urorin da ke amfani da batir suna tallata rayuwar batir har zuwa shekaru 10. Sensors na gas a cikin ƙararrawar CO suna da iyakantaccen rayuwa, yawanci shekaru biyu zuwa biyar.[5] An tsara sabbin samfuran don nuna buƙatar maye gurbin bayan wani lokaci. Masu gano CO duk suna da maɓallan "gwaje-gwaje" kamar masu gano hayaki, amma maɓallan gwajin kawai suna gwada batir, kewayon lantarki, da buzzer, ba ikon ƙararrawa na jin gas ba.
Dangane da jagororin carbon monoxide na Ƙungiyar Kare Wutar Kasa, ya kamata a shigar da masu gano CO a kowane wurin bacci a cikin gida, kuma kowane mai ganowa ya kamata a kasance "a kan bango, rufi ko wani wuri kamar yadda aka ƙayyade a cikin umarnin shigarwa da ke tare da naúrar".
Ana samun masu gano CO a matsayin samfuran da suka tsaya, ko na'urorin da aka haɗa da tsarin waɗanda za a iya saka idanu daga nesa.
Ayyuka
[gyara sashe | gyara masomin]Babban manufar masu gano CO shine yin ƙararrawa don gargadi mazauna game da sararin samaniya mai haɗari na carbon monoxide. Ya kamata ƙararrawa ta yi sauti a cikin minti 60 idan maida hankali ya tashi zuwa 70 PPM, a cikin minti 10 a 150 PPM, cikin minti 4 a 400 PPM, kuma nan da nan a 500 PPM ko mafi girma. Bai kamata ƙararrawa ta yi saurin sauti ba, saboda taƙaitaccen ƙararrawa na ƙarya na iya sa masu amfani su kashe ƙararrawa, suna barin su ba tare da kariya ba.[6] Wasu na'urorin ƙararrawa na iya nuna matakin CO. Har ila yau, akwai kayan auna da aka tsara don nuna maida hankali ga CO zuwa ƙananan matakan da ba su da haɗari, maimakon ganowa da gargadi game da matakan haɗari.
Wasu masu ganowa ba tare da takardar shaidar UL ba an gano su ba su yi sauti a ƙofar da aka ƙayyade ba, ko kuma su yi sauti cikin seconds.[6]
A wasu lokuta, ya cancanci a lura cewa ja mai haske ba tare da sautuna ba zai iya nuna wani yanayi daban ko kuma kawai ya sanar da mai amfani game da rashin aiki.[7]
Ana samun na'urorin tsaro na gida marasa waya waɗanda ke haɗa masu gano carbon monoxide zuwa matashin matattarar matattarar, strobes, ko wayar gargadi mai nisa.
Ana amfani da hanyoyi da yawa na gano carbon monoxide kuma an rubuta su a cikin ƙayyadaddun masana'antu da aka buga ta Underwriters Laboratories. Hanyoyin gargadi sun hada da:
- Sautin da ake ji (4 gajerun bugawa) Ya bambanta tsakanin 3,000 da 3,500 Hz dangane da alama da sunan samfurin 105 dB murya a 3 feet
- Ya bambanta tsakanin 3,000 da 3,500 Hz dangane da alama da sunan samfurin
