Abasebenzi badibanisa i-hoses kwi-hydrant kwaye bafikelela zombini i-dock kunye nenqanawa. Unikezelo lwamanzi oluguquguqukayo lwenza kube lula ukunqanda umlilo kunye nokuthintela umonakalo kwezinye iinqanawa. Le mizekelo ibonisa ukuba iindlela ezintathu zokucima umlilo zixhasa imisebenzi enzima yokucima umlilo kwiimeko zehlabathi zokwenyani.

Ukukhetha phakathi kweeNdlela ezimbini zoMlilo weHydrant kunye neeNdlela ezintathu zoMlilo

Izinto Emaziqwalaselwe

Ukukhetha uhlobo olululo lombhobho womlilo kufuna ukuphononongwa ngononophelo kwezinto ezininzi ezibalulekileyo. Abacwangcisi bokhuseleko lomlilo bajonga ubungakanani bendawo, imfuno elindelekileyo yamanzi, kunye neentlobo zezakhiwo ezikhoyo. Bakwaqwalasela nenani lemibhobho yomlilo ekunokufuneka isebenze ngaxeshanye.

• Ukuhamba kwamanzi kuyafuneka:Iindawo zokuhlala ezinoxinano oluphezulu kunye neendawo zoshishino zihlala zifuna isantya esiphezulu sokuhamba kwamanzi. Ngokomzekelo, iingcali zincoma izinga lokuhamba kweelitha ezingama-30 ngesibini kuzo zombini iindawo zokuhlala ezinoxinano oluphezulu kunye nezorhwebo okanye zoshishino, kunye nexesha lokubonelela ngeeyure ezine. Iindawo zokuhlala ezinoxinano oluphantsi zidla ngokufuna iilitha ezili-15 ngomzuzwana kwiiyure ezimbini.
• Isithuba kunye noFikelelo:Ezinye iindawo zinendawo encinane yokufakela. AIindlela ezimbini zoMlilo weHydrantingena kakuhle kwizitrato ezimxinwa okanye kwiindawo ezincinci. Iindlela ezintathu ze-hydrants zifuna indawo eyongezelelekileyo kodwa zibonelela ngokuguquguquka okukhulu kumaqela amakhulu.
• Uhlobo lwesakhiwo kunye neNqanaba loMngcipheko:Iipaki zemizi-mveliso, iifektri, kunye nezakhiwo zorhwebo zijongene nemingcipheko ephezulu yomlilo. Ezi ndawo zixhamla kwii-hydrants ezinokuxhasa i-hoses ezininzi kunye nokuhambisa umthamo omkhulu wamanzi ngokukhawuleza.
• Imozulu kunye noHlobo lweNkqubo:Kwiindawo ezibandayo okanye kwiindawo ezingenakufudumala, iinkqubo zemibhobho eyomileyo zithintela ukukhenkceza. Iinkqubo zemibhobho emanzi zisebenza kakuhle kwiindawo zokuhlala ngokubanzi. Iinkqubo zezandyondyo zemvula zihambelana neendawo ezinobungozi obuphezulu, njengezityalo zekhemikhali, apho ukuhanjiswa kwamanzi ngokukhawuleza kubaluleke kakhulu.

Amasebe omlilo kufuneka ahambelane nodidi lwe-hydrant kwiimfuno ezithile zendawo. Le ndlela iqinisekisa unikezelo lwamanzi oluthembekileyo kunye noncedo olusebenzayo olungxamisekileyo.

---

Iindlela ezimbini zoMlilo weHydrantiimodeli zinika ukuhamba kwamanzi okuthembekileyo kwizakhiwo ezincinci, ngelixa iindlela ezintathu ze-hydrants zikhonza iindawo ezinkulu, ezinomngcipheko ophezulu. Iingcali zokhuseleko lomlilo zincoma ukukhetha iintlobo ze-hydrant ngokusekelwe kubukhulu besakhiwo, imfuno yamanzi, kunye neekhowudi zendawo. Uluntu kufuneka luqinisekise ukuba ii-hydrants zihlala zibonakala, zifikeleleka, kwaye zigcinwa rhoqo ukulungiselela impendulo esebenzayo yongxamiseko.

• Iinkqubo zangaphakathi ze-hydrant zilungele ukuphakama okuphezulu.
• Imibhobho yamanzi yangaphandle ilingana nemimandla yasezidolophini neyemizi-mveliso.
• Ukubekwa ngokufanelekileyo kunye novavanyo oluqhelekileyo luphucula ukhuseleko.

FAQ

Loluphi uncedo olungundoqo lombhobho wokucima umlilo oneendlela ezintathu?

A iindlela ezintathu zokucima umliloivumela abacimi bomlilo ukuba badibanise imibhobho emininzi. Olu phawu lwandisa ukuhamba kwamanzi kwaye luxhasa amaqela amakhulu okucima umlilo ngexesha likaxakeka.

Ngaba umbhobho wokucima umlilo ungaphuculwa ube yimodeli eneendlela ezintathu?

Hayi, ukuphuculwa kweendlela ezimbini zehydrant kwimodeli yeendlela ezintathu kufuna ukubuyisela iyunithi yonke. Uyilo kunye nolwakhiwo lwahluke kakhulu.

Kufuneka zigcinwe kangaphi imibhobho yokucima umlilo?

Iingcali zokhuseleko lomlilo zincoma ukuba kuhlolwe kwaye kugcinwe i-hydrants ubuncinane kanye ngonyaka. Ukuhlolwa rhoqo kuqinisekisa ukusebenza okuthembekileyo kunye nokuphendula ngokukhawuleza ngokukhawuleza.
