Iyini Ithangi Eliyisipele Somlilo?
Ithangi lokugcina amanzi omlilo (fire reserve tank) liyisitsha esimile esiklanyelwe ukuhlinzeka ngamanzi anokwethenjelwa futhi asheshe atholakale ezinhlelweni zokucisha umlilo (ezifana nezifutho, amahydrant, namapayipi ami ngezwi). Ezimweni lapho amapayipi amanzi omasipala engakwazi ukuqinisekisa izinga lokugeleza noma ingcindezi edingekayo ngesikhathi somlilo, ithangi lokugcina amanzi omlilo liqinisekisa ukuthi indawo inomthombo wamanzi ozimele owanele ukusekela ukuvikelwa omlilo okusebenzayo isikhathi esithile (imvamisa amahora angu-2 kuya kwangu-4).
Lawama thangi ayisici 'esivikelekile' sohlelo lokuvikela umlilo lwezimboni noma lwezentengiselwano, aqinisekisa ukuthi uhlelo lokucisha umlilo alunaso isidingo samandla angaphandle noma ukuqina kwegridi yezinsiza zomphakathi.
Izidingo Ezibalulekile Zobunjiniyela
Ukuze isebenze njengempahla yokuphepha kwempilo, ithangi eliyisipele somlilo kumele lakhiwe ngokwezindinganiso ezithile zamazwe ngamazwe, ikakhulukazi i-NFPA 22 (Izinga Lamathangi Amanzi Okusetshenziswa Komlilo Wangasese).
1. Umthamo Oqinisekisiwe Nengcindezi Emile
Ithangi kumele likalwe ngokusekelwe ezingeni lengozi lesikhungo (Ukukhanya, Okujwayelekile, noma Ingozi Eyengeziwe). Amathimba obunjiniyela abala umthamo odingekayo ngokusekelwe esidingweni sohlelo lokufafaza (GPM) siphindaphindwe isikhathi esidingekayo sokuvikela.
2. Ukuvikelwa Kokugqwala
Ngenxa yokuthi amanzi esizindalwazi omilio ahlala isikhathi eside emile, ukugqwala kwangaphakathi kuwusongo olukhulu ekuphileni kwethangi.
● Izinhlelo Zokufaka: Izinto zokufaka eziphambili ezifana ne-Glass-Fused-to-Steel (GFS) noma i-Fusion-Bonded Epoxy (FBE) ziyathandwa ngoba zinikeza umgoqo ongenazimbotshana, ongenakugqwala ovimbela ukunqwabelana kwenhlabathi.
● Ukuvikelwa Kwe-Cathodic: Kuvame ukudingeka ukuze kuncishiswe ukusabela kwamakhemikhali kagesi okubangela ukugqwala kwensimbi, ikakhulukazi phansi kwethangi.
3. Ingqalasizinda Enikelwe Yona
Amanzi omlilo kumele ahlukaniswe ngokuqinile namanzi enqubo noma okuphuza. Ukuhlelwa kwethangi kumele kufake:
● Amapayipi Okumunca Anikelwe Yona: Abekwe ukuze avimbele ukungenwa kwenhlabathi noma ukwakheka kwe-vortex.
● Amapuleti Okuvimbela I-Vortex: Abalulekile ukuze kuvinjwe ukungena komoya emgqeni wokumunca wepompu ngesikhathi sokukhipha amanzi ngejubane elikhulu.
Ukuhlaziywa Kwezinto Ezibonakalayo Okuqhathanisayo
Uma kucaciswa ithangi eliyisipele somlilo, onjiniyela bahlola ukuqina kwesakhiwo, izidingo zokunakekela, kanye nezikhathi zokufakwa.
Isixazululo Sokugcina | Indlela Yokuhlanganisa | Ubukhulu Bokunakekela | Ukuguquguquka Komklamo |
Insimbi Ehlanganisiwe (GFS/FBE) | Imodula, Ehlanganisiwe | Iphansi Kakhulu | Phezulu (Iyakhuliswa) |
Insimbi Ehlanganiswe Endaweni | Ukuhlanganisa Endaweni | Phezulu (Ukupenda Okuvamile) | Iphansi |
Ukhonkolo (Oluthelwa Endaweni) | Luthelwa endaweni | Okulingene (Ukulungiswa Komugqa) | Iphansi |
Inani Lamathangi Enziwe Efekthri Ahlanganisiwe
Ukuklanywa kwesimanje kokuvikela umlilo kuthanda kakhulu amathangi ensimbi abolthiwe akhiwe efemini (anjenge-Glass-Fused-to-Steel) ngenxa yezizathu ezimbalwa ezibalulekile:
● Ukuvumelana Kwekhwalithi: Ngokungafani namathangi ahanjiswa ngokushisela, lapho ikhwalithi incike emandleni abashiseli bendawo kanye nezimo zezulu zasendaweni, amaphaneli abolthiwe ayakhiwa, ahlanganiswe, futhi ahlolwe efemini ehlanzekile, enesimo sezulu esilawulwayo.
● Ukusatshalaliswa Okusheshayo: Amaphaneli amojula athwalwa kalula futhi ahlanganiswe, kunciphisa kakhulu "isikhathi sokuthobela" izikhungo ezintsha noma amaphrojekthi okwandisa.
● Ukunakekela Okuncane: Ubuchwepheshe be-GFS buqeda isidingo sokupenda kabusha ngezikhathi ezithile, okuyindleko enkulu yokusebenza yamathangi ensimbi ahanjiswa ngokushisela endaweni.
Imibuzo Evame Ukubuzwa (FAQ)
Umbuzo: Ingabe amathangi okugcina amanzi omlilo ayadingwa ngokomthetho?
A: Ezindaweni eziningi eziphethe umthetho, ziyadingeka ezikhungweni zezimboni, ezakhiweni eziphakeme, nasezindaweni zokugcina izimpahla lapho uhlelo lwamanzi lukamasipala wendawo lungakwazi ukuqinisekisa ukugeleza nokucindezela okudingwa izibalo zohlelo lwezifutho zomlilo wesakhiwo. Ukuthobela umthetho ngokuvamile kulawulwa yimithetho yomlilo yendawo kanye ne-NFPA 22.
Q: Ngingazi kanjani ukuthi ngidinga ithangi elingakanani?
A: Ubukhulu bethangi bunqunywa nguNjiniyela Wokuvikela Umlilo (FPE). Ubukhulu bungumsebenzi wesigaba sengozi yesakhiwo (isibonelo, indawo yokugcina izinto ezivuthayo eziphakeme idinga ithangi elikhulu kunehhovisi elincane), isidingo sokugeleza kohlelo lwezifutho, kanye nesikhathi esidingekayo sokuphakelwa kwamanzi.
Q: Kungani ngingeke nje ngisebenzise ithangi elijwayelekile lokugcina amanzi?
A: Ithangi elihlelelwe ukuba yindawo yokugcina amanzi omlilo kumele lihlangabezane nezindinganiso ezithile zokuphepha (ezifana nezidingo ze-NFPA 22 noma ze-FM Global). Amathangi ajwayelekile okugeza amanzi angase angabi nokuqiniswa okudingekayo kokuzamazama komhlaba, ukuhlelwa okuthile kwamapayipi okudonsa, noma ukuqina okuqinisekisiwe okudingekayo ekusetshenzisweni okuphephisa ukuphila.
Q: Ithangi lomlilo lokugcina amanzi kumele lihlolwe kangaki?
A: Ngokwe-NFPA 25 (Izinga Lokuhlola, Ukuhlola, Nokugcinwa Kwezinhlelo Zokuvikela Umlilo Ezinamanzi), amathangi amanzi omlilo adinga ukuhlolwa okuvamile okubonakalayo kanye nokugcinwa okuhleliwe ukuze kuqinisekiswe ukuthi ithangi, ikhwalithi yamanzi, namapayipi okudonsa ahlala esebenza futhi engenazo izithiyo.
Q: Ingabe amanzi asethangini lomlilo lokugcina adinga ukwelashwa?
A: Ikhwalithi yamanzi ibalulekile. Nakuba kungadingeki ukuthi abe "ngokuphuzwayo," kumele angabi nemfucumfucu engavala izihloko zokufafaza. Kwezinye izimo, kufakwa izinhlelo zokujikeleza ukuze kuvinjelwe amanzi ukuthi angami, okungase kusekele ukukhula kwezinto eziphilayo.
Ingabe njengamanje ucacisa ingqalasizinda yephrojekthi yokuvikela umlilo? Ukuqonda ukuhlangana kwesayensi yezinto ezibonakalayo nokuthobela izimiso zokuphepha kwempilo kubalulekile ekuphathweni kwesikhungo ngempumelelo. Xhumana nethimba lethu lobuchwepheshe uma udinga ukuholwa mayelana nosayizi noma ukukhethwa kwezinto zohlelo lwakho lokugcina amanzi omlilo.
