Kudzipatula kwa makina - Lockout/Tagout

Popeza kuti zida zosuntha za makina sizimachotsedwa bwino, ngozi zachitetezo cha kupanga za anthu omwe amavulala chifukwa cha anthu omwe amalowa m'malo oopsa omwe amakakamizidwa ndi zida zoyendetsedwa nthawi zambiri zimachitika. Mwachitsanzo, mu Julayi 2021, wantchito ku kampani ya ku Shanghai anaswa malangizo ogwirira ntchito, anatsegula chitseko choteteza popanda chilolezo, analowa mu rack yosungiramo galasi kwakanthawi kuti asinthe malo a galasi, ndipo anaphwanyidwa mpaka kufa ndi chothandizira chonyamula katundu chosuntha.

Pankhaniyi, wantchitoyo anatsegula kaye chitseko choteteza cha shelufu yagalasi asanalowemo. Kuchokera apa zitha kuwoneka kuti chiopsezo cha zida zam'manja mu shelufu yagalasi chadziwika kale, ndipo chitseko choteteza chimagwiritsidwa ntchito kupatula ndikuteteza malo oopsa awa. Ndiye, kodi chitseko choteteza chiyenera kukhazikitsidwa bwanji? Choyamba, zida zoteteza zitha kugawidwa m'zida zoteteza zokhazikika ndi zida zoteteza zoyenda. Zipangizo zoteteza zokhazikika ziyenera kukonzedwa mwanjira inayake (monga ndi zomangira, mtedza, kuwotcherera) ndipo zitha kutsegulidwa kapena kuchotsedwa pogwiritsa ntchito zida kapena kuswa njira yokonzera. Zoteteza zosunthika zitha kutsegulidwa popanda kugwiritsa ntchito zida, koma zikatsegulidwa, ziyenera kukhazikika pamakina kapena kapangidwe kake momwe zingathere ndipo ziyenera kutsekedwa (ndi maloko oteteza ngati pakufunika). Chifukwa chake, chitseko choteteza pangozi sichingadziwike ngati chipangizo choteteza, kapena sichingagwire ntchito ngati chipangizo choteteza.

Kukhazikitsa zida zodzitetezera zogwira mtima kungalepheretse antchito kulowa m'malo oopsa mwangozi, koma sizikutanthauza kuti gwero la ngozi ndi antchito alekanitsidwa kwathunthu. Nthawi zambiri, antchito amafunika kulowa m'malo oopsa mwadala kuti athetse zolakwika pakupanga ndi kukonza. Pankhaniyi, ndikofunikira kwambiri kuyambitsa njira yodzipatula mphamvu ndikuyigwiritsa ntchito mosamala. Iyi ndi njira yofunika kwambiri yowongolera zoopsa yomwe mabizinesi ambiri akugwiritsa ntchito, monga njira yodziwika bwino yodziwira zoopsa.Kutseka/Kutulutsadongosolo. Makampani osiyanasiyana ali ndi matanthauzidwe osiyanasiyana a ma lock tag, ena amatchedwaLOTO, zomwe zikutanthauza kutseka kunja, tag out; Amadziwikanso kuti LTCT, lock, Tag, Clean, test. Mu GB/T 33579-2017 Machine Safety Hazard Energy Control Method Locking Tag,Kutseka/KutulutsaKutanthauzidwa ngati kuyika loko/chizindikiro pa chipangizo cholekanitsa mphamvu motsatira njira yokhazikitsidwa kuti kusonyeze kuti chipangizo cholekanitsa mphamvu sichiyenera kugwiritsidwa ntchito mpaka chitachotsedwa motsatira njira yokhazikitsidwa.

Kutseka/Kutulutsaamaloledwa kugwiritsidwa ntchito payekhapayekha mu muyezo wa NATIONAL, koma m'machitidwe, chizindikirocho chingagwiritsidwe ntchito payekhapayekha nthawi zina, monga kuchotsa chipangizocho ndikuchiyika mkati mwa mita imodzi kuchokera kumbali. Nthawi zambiri, kutseka ndi kuyika chizindikiro kuyenera kugwiritsidwa ntchito pamodzi. Komabe, ntchito zosiyanasiyana zimakhala ndi zoopsa ndi mikhalidwe yosiyanasiyana, zina zimayambitsa zotsatira zazing'ono, zina zimatha kupha, zina zimatha kupatula magwero amagetsi, ndipo zina zimafunika kupatula mphamvu yokoka.

Mu ntchito yanga, nthawi zambiri ndimakhala ndi mavuto ndi anzanga a dipatimenti yopanga mphamvu, monga kugwiritsa ntchito khushoni loyimitsa lopangidwa kunyumba pansi pa kukankhira zida kuti zisagwere mzere osati mzere, maloko amagetsi pamzere osati mzere, palibe njira yoyesera kuyambitsa zida kuchokera munjira yolingana ndi njira zowongolera mu mkhalidwe woyimitsa pa gudumu, kuchotsa chisokonezo cha mzere osati mzere, ndi zina zotero pamavuto amitundu yonse, Chifukwa chake, m'malo moganizira za vuto limodzi pambuyo pa lina, ndikuganiza kuti ndibwino kupanga njira yokhazikika yothetsera mavuto otere kuti ogwira ntchito kutsogolo athe kuchita kusanthula zoopsa pawokha ndikupanga njira zodzitetezera. Pachifukwa ichi, ndinapanga njira ya magawo asanu ndi awiri yodziwira njira zodzipatula mphamvu molingana ndi miyezo yoyenera yachitetezo cha makina ndi machitidwe ena a fakitale, ndipo ndinayambitsa ndikuyigwiritsa ntchito pang'onopang'ono potchula ngozi zovulala zomwe zatchulidwa pamwambapa.
