Loto, yomwe imatchulidwa kuti lockout-tagout.OSHA ndi njira yovomerezeka ya OSHA yopewera kuvulala mwa kudzipatula kapena kutseka magwero ena owopsa a mphamvu.Yakhala ikugwiritsidwa ntchito kwambiri padziko lonse lapansi, ndipo tsopano yatulukira pa nthawi yoyenera ku China.Palinso mafotokozedwe oyenera mu Safety Production Law.Palinso makonzedwe apadera mu dziko lokhalo lovomerezedwa ndi makampani ochizira kutentha kwamtundu wa GB 15735 2012, Zofunikira za Chitetezo ndi Ukhondo pa Njira Yopangira Kutentha kwa Zitsulo.Cholinga chake ndikuteteza ogwira ntchito ku kuwonongeka kwa mphamvu zamakina, kuphatikiza wogwira ntchito aliyense amene akufunika kulumikizana kapena kugwira ntchito pafupi ndi makina kapena zida zomwe zili ndi mphamvu zosungidwa.Njira yeniyeni ndikutseka mphamvu pakuyika \ kukonza \ kusintha \ kuyang'anira \ zida zoyeretsera, ndikuwonetsa kuti ntchito yokonza ikuchitika ndi tag pamene loko kulibe, ndikuyesa pambuyo pochita pamwamba pa ntchito.
