Eni nyumba akuyenera kuyika zowunikira zovomerezeka (BS EN 50291) m'chipinda chilichonse chomwe chili ndi zida zoyatsira zosakhazikika. Zipangizo zamagesi ziyenera kutumizidwa chaka chilichonse ndi mainjiniya otetezedwa a Gasi.

Pakachitika ngozi, anthu oyimba 999 kuti azimitsa moto kapena 0800 111 999 panjira yadzidzidzi yapadziko lonse lapansi. Kutumiza kwa apolisi osakhala angozi kwafika pa 101.

European Union: Miyezo ya EN 50291 ndi kusesa kwa dziko¶

Machitidwe a Continental European amagwirizana ndi European Norm EN 50291 ya zowunikira zapanyumba za carbon monoxide.

Maiko monga Germany ndi Austria amakakamiza kuwunika kwa chitoliro kwapachaka kochitidwa ndi kuseseratu kwa chimney. Ma flue ophatikizika ophatikizika m'nyumba zogona zaku France amakumana ndi macheke okhwima okhudzana ndi mpweya wabwino.

M'maiko onse omwe ali mamembala a European Union, imbani 112 kuti mupeze chithandizo chadzidzidzi.

Australia: National Construction Code ndi chitetezo chanyumba¶

Ku Australia, nsanja za mabanja ambiri zimagwera pansi pa National Construction Code, ndipo chitetezo chimayang'aniridwa ndi akuluakulu aboma.

Makina apakati owonjezera madzi gasi ndi mizere ya gasi wapanyumba ayenera kuyikidwa ndi zoyezera gasi zovomerezeka pansi pamiyezo ya AS/NZS 5601. Eni nyumba ayenera kusamalira zida zamagetsi zamagetsi zomwe zikuyenda bwino. Pazidzidzidzi, anthu aku Australia amayimba 000 kuti ayankhe moto wamoto.

Njira zothamangitsira pambuyo pothawa komanso zomanga zovomerezeka¶

Mukatuluka mnyumbamo, ngoziyi ili kutali. Kulowanso kotetezedwa kumafuna kutsimikizira kwasayansi kochitidwa ndi akatswiri odziwa zadzidzidzi:

Osalowanso mnyumbamo mpaka mkulu wa dipatimenti yozimitsa moto atapereka chidziwitso chomveka bwino. Osatengera mawu a wogwira ntchito yokonza nyumba, eni nyumba, kapena wokhala mnzako kuti ndi bwino kubwerera.

Ozimitsa moto amatumiza zowunikira zowunikira mpweya wambiri kuti zisese pansi, kuthamangitsa zofunikira, ndi chipinda chamakina chapansi:

Oyankha amayesa momwe mpweya ulili pansi, kutalika kwa malo opumira, komanso kutalika kwa siling'i pamayunitsi angapo.

Ozimitsa moto amakhazikitsa lamulo loletsa chilolezo. M'madera ambiri, ogwira ntchito sangalole kuti munthu alowenso mpaka milingo ya carbon monoxide yatsimikiziridwa pansi pa 9 ppm m'nyumba yonseyo.

Ngati kutayikirako kudachokera ku boiler yapakati kapena makina otenthetsera madzi, dipatimenti yozimitsa moto kapena katswiri wazogwiritsa ntchito gasi adzatsekera valavu yoperekera mafuta pogwiritsa ntchito loko ndi tagi yochenjeza. Chida chowotchera sichingapatsidwenso mphamvu mwalamulo mpaka wopanga makina omwe ali ndi chilolezo adzayang'ane makinawo, kukonza chitoliro chomwe chaphwanyidwa kapena chotenthetsera kutentha, ndikupereka zikalata zovomerezeka kwa ozimitsa moto wapafupi.

Pitani kukayezetsa kuchipatala ngati aliyense ali ndi zizindikiro. Mpweya wa carbon monoxide umatuluka pang'onopang'ono pamene ukupuma mpweya wabwino wa chipinda, ndi theka la moyo wa maola 4 mpaka 5. Madipatimenti odzidzimutsa amapereka mpweya wa 100 peresenti ya normobaric pogwiritsa ntchito masks osatsitsimula, kuchepetsa theka la moyo mpaka 60 kwa mphindi 80, kapena kupereka chithandizo cham'chipinda cha hyperbaric kuti ateteze kuvulala kwa nthawi yaitali kwa mitsempha.

Mafunso omwe amafunsidwa pafupipafupi¶

Kodi carbon monoxide imatha kudutsa makoma a nyumba ndi kudenga?¶

Inde. Ngakhale mpweya wa carbon monoxide susungunuka mwachindunji kudzera mu konkriti wothira, umalowa mosavuta m'mabanja ambiri kudzera m'mipata ing'onoing'ono, ma porous drywall seams, kuthamangitsa mapaipi, magetsi, ndi ma ducts olowera mpweya. Chifukwa mpweya wa carbon monoxide umasakanikirana ndi mpweya, kusiyanasiyana kwa mphamvu ya zomangamanga kumakokera mpweya wapoizoniwo kudzera m'mabowo a khoma ndi malo olowera pansi osatsekedwa kuchokera kuchipinda china kupita kwina.

N’chifukwa chiyani alamu ya m’nyumba yathu ya m’chipinda chapamwamba inalira ngati chowotchera chili m’chipinda chapansi?¶

Izi zimachitika chifukwa cha kukwera kwakukulu kwa stack effect. M'nyengo yozizira, mpweya wotentha wamkati umakwera pamwamba pa denga, zomwe zimapangitsa kuti pakhale kupanikizika kwapansi komanso kupanikizika kwapamwamba. Chitoliro cha boiler chikaphulika m'chipinda chapansi, mpweya wotenthawu umayamwa mpweya woyaka wapoizoni molunjika kudzera m'miyendo ya zinyalala, machubu a zinyalala, ndi kuthamangitsa mapaipi, ndikutaya mpweya wochuluka wa carbon monoxide molunjika pamalo apamwamba kwambiri.

Kodi ndi bwino kutsegula mawindo athu ndikukhala m'nyumba?¶

Ayi. Kutsegula mazenera ndikowopsa panthawi yadzidzidzi yamitundu yambiri ya carbon monoxide. Ngati nyumba yanu ikukhala pamalo oponderezedwa ndi nyumbayo, kutsegula zenera kumatha kufulumizitsa kuchulukirachulukira, kutulutsa mpweya wapoizoni wochulukirapo m'mipando yamkati ndikuthamangitsa malo anu okhala. Komanso, kukhala mkati kumakupangitsani kuti mukhale poizoni wopitilira ngati mphepo isuntha. Chotsani nyumbayi nthawi yomweyo mumpweya wabwino wakunja.

Kodi ndingatani ndikamva chowunikira chikulira m'nyumba yoyandikana nayo yopanda kanthu?¶

Tetezani ma alarm omwe simukuwayang'anira m'nyumba yoyandikana nawo ngati ngozi yoteteza moyo. Musanyalanyaze kapena kuganiza kuti ndi batire yakufa. Gondotsani chitseko mwamphamvu kuti mutsimikizire ngati wokhalamo wakomoka, chotsani chipangizo chanu nthawi yomweyo, ndipo imbani nambala yanu yazadzidzi yapafupi kunja kwa nyumbayo. Dziwitsani otumiza kuti alamu yakhala ikulira mosalekeza m'dera loyandikana nalo ndikupereka nambala yeniyeni yanyumba.

Kodi kutsegula chitseko cha masitepe kumathandizira kuchotsa gasi mumsewu?¶

Ayi. Osatsegula kapena kutsegula chitseko chozimitsa moto pa alarm. Masitepe otuluka amapangidwa ngati malo otetezedwa otetezedwa ndi moto. Kutsegula chitseko cha masitepe kumathyola chisindikizo chosindikizira ndikusintha nsanjayo kukhala chumuni chachikulu, kujambula mpweya woipa wa carbon monoxide kuchokera m'makonde okwera m'masitepe ndikuchititsa khungu kapena kufooketsa anthu omwe akufuna kuthawa pamalo okwera.

Chitsimikizo cha thandizo loyamba¶

Zadzidzidzi zakupha poyizoni wa carbon monoxide m'nyumba zokhala ndi mabanja ambiri zimakhala ndi zovuta zachipatala zomwe zimakhala zovuta kwambiri pomwe owonera amatha kupewa ngozi zowopsa. Kudziwa momwe mungayang'anire mnansi amene akomoka, mayendedwe oyenda bwino, kupereka okosijeni wowonjezera wothamanga kwambiri, komanso kupereka kupsinjika pachifuwa pakumangidwa kwamtima mwadzidzidzi kumapangitsa kusiyana kwanthawi yayitali ya moyo kapena imfa.
