Umgaqo wokusebenza
● Phantsi kweemeko eziqhelekileyo zokusebenza, ivalve ihlala ivaliwe.
● Uxinzelelo oluthile lubekwe ngokulungelelanisa intwasahlobo kunye ne-nut yoxinzelelo.
● Xa uxinzelelo kwimibhobho lungaphezu koxinzelelo oluthile, ivalve ivuleka ngokuzenzekelayo ukwenza ulwelo ludlule ukuze kuncitshiswe uxinzelelo kwimibhobho.
●Ivalve inokuba nesiphatho ukuze ikwazi ukuvuleka ngokuyinxenye.Xa isiphatho sihlala sivulekile kwindawo yokusebenza, isicoci sinokuhamba ngeevalvu.
