Lapho okokusebenza noma ithuluzi kulungiswa, kunakekelwa noma kuhlanzwa, umthombo wamandla ohlobene nesidingo semishini
ukuze inqanyulwe, ukuze okokusebenza kungaqalwa, futhi yonke imithombo yamandla (ukunikezwa kwamandla, umthombo we-hydraulic, umthombo womoya, njll.) iyacishwa.
Vala ngaphandle: I-Lockout isebenzisa ukuphepha nezinye izinto zokusebenza ukukhiya umshini ukuze uhlukaniseke nemisebenzi engagunyaziwe kanye nokuqinisekisa ukuphepha komsebenzi ngamunye kuze kube yilapho umsebenzi usuphelile.
I-Tag out: I-Tagout isetshenziselwa ukuxwayisa abantu ukuthi umthombo wamandla noma okokusebenza kukhiyiwe okungeke kusetshenziswe ngokuzithandela.
Ukunqamula kusho: Ucezu olulodwa noma isisetshenziswa seqembu esisodwa singanqamula umthombo wamandla noma isekethe yokuphakela amandla.
I-LOTO: Ukuze kuqinisekiswe ukuthi amandla emishini avaliwe, okokusebenza kugcinwa esimweni esiphephile.Vimbela ukulimala kwamazinyo kwe-acci kubasebenzi noma kumuntu ohlobene ngaphakathi noma eduze kwamathuluzi okubangelwa umshini osetshenziswe ngephutha.
