Tshixa ithegi ngaphandle-Amanqaku aphambili okubekelwa bucala kwamandla

Ityala leNgozi 1
Xa umsebenzi wekontraka wayeqhaqha umbhobho ezantsi kombhobho womlilo ivelufa yebhola e-1 (kusekho ucinezelo oluya phezulu kwivalve yebhola), umzimba wevalve yebhola uye waqhawuka ngempazamo.Ibhola yentsimbi ngaphakathi kumzimba wevalve yakhutshwa ngokukhawuleza ngamanzi omlilo kwaye yabetha umqeshwa ebusweni.Ngethamsanqa, umqeshwa wayenxibe iindondo zokhuseleko ngelo xesha kwaye akazange enze konzakala kakhulu.
Ngowuphi unobangela wale ngozi?

Ityala leNgozi 2
Xa umsebenzi wekontraka wayethatha iisampulu zeoyile yokuthambisa kwicompressor yomoya ekwimeko yokulinda, uxinzelelo lwenkqubo yomoya ecinezelweyo lwehla ngenxa yokusetyenziswa kakhulu kwamanzi okomba kwiqonga lomlenze wemfumba kumgangatho wokomba, kwaye icompressor yomoya ngequbuliso yaqala, ebangela uxinzelelo kwinkqubo yeoli yokuthambisa, kwaye isandla somqeshwa satshiswa yioli yokuthambisa yobushushu obuphezulu obuchithekileyo.
Ngowuphi unobangela wale ngozi?

Amanqaku aphambili okuhlukaniswa kwamandla
Ukwazi ukuchonga ukuba yeyiphi imisebenzi efuna ukwahlulwa kwamandla:
Iphepha-mvume lokusebenza kufuneka lifakwe kuwo wonke umsebenzi ongengowesiqhelo;
Umniki-mvume yokusebenza kunye nomntu obhalwe phantsi ukuze abe ilifa baye banxibelelana ngokuzeleyo ngalo msebenzi ucetywayo;
Umniki welayisenisi kunye nomntu omele abe yedwa uqhelene nesixhobo kunye nenkqubo yoncedo.

Amanqaku aphambili okwahlulwa kwamandla 2
Indlela kunye nento yokwahlulwa kwamandla ichanekile:
Ukwahlukaniswa kwenziwa kuphela ngoqeqesho olukhethekileyo, iimviwo eziphumeleleyo, kunye “nababodwa” abagunyazisiweyo;
Emva kokuba i-quarantine igqityiwe, qinisekisa into evalelweyo ukuqinisekisa ukuba i-quarantine ichanekile;
