Ukuhlolwa ngaphambi kokusebenza komshini wokuqhumisa

Umsebenzi wokuhlola ngaphambi kokuqala i-imishini yokuqhumisa umshini wokudubulaikakhulukazi kufaka:

Okokuqala, ngaphambi kokuqala i-umshini wokuqhuma wokudubula, sidinga ukubheka ukuthi ukuthambisa kwazo zonke izingxenye zemishini kuyahlangabezana yini nemithetho.
Okwesibili, ngaphambi kokusebenza okusemthethweni kwe-imishini yokuqhumisa umshini wokudubula, kuyadingeka ukuhlola ukugqokwa kwezingxenye ezisengozini njengamapuleti onogada, amakhethini enjoloba nezipikha, bese uzishintsha ngesikhathi.
Okwesithathu, futhi sidinga ukubheka ukuthi ngabe kukhona yini amanye amaswidi ezintweni eziwela emshinini. Uma kukhona, sicela usule ngesikhathi ukuvimbela ukuvinjelwa kwesixhumanisi ngasinye sokudlulisa futhi kubangele ukwehluleka kwemishini.
Okwesine, hlola ukulingana kwezingxenye ezihambayo, noma ngabe ukuxhumana kwe-bolt kukhululekile, bese ukuqinisa ngesikhathi.

Okwesihlanu, ngaphambi kokuqala umshini, kuphela uma kuqinisekiswa ukuthi akukho muntu egumbini futhi umnyango wokuhlola uvaliwe futhi unokwethenjelwa, ungakulungela ukuqala. Ngaphambi kokuqala umshini, kufanele kuthunyelwe isignali yokwenza abantu abaseduze komshini bahambe.
