Kodi mungasankhe bwanji zinthu zomangira loko la loko yotetezera mafakitale?

Pankhani ya chitetezo cha mafakitale,LOTO (Lockout/Tagout)Ndi njira yofunika kwambiri yotetezera kuti tipewe ngozi zomwe zimachitika chifukwa cha zida zoyambitsidwa mwadzidzidzi. Imagwira ntchito ngati njira yomaliza yotetezera miyoyo ya anthu. Monga "mlonda" weniweni wa mzere wodzitetezera uwu - maloko achitetezo a mafakitale - kusankha zida zotsekera si nkhani yaing'ono. Imatsimikizira mwachindunji ngati loko ikhoza kukhalabe pamalo ake m'malo ovuta monga chinyezi, dzimbiri, ndi magetsi ambiri, zomwe zimapangitsa kuti "yotsekedwa = yotetezeka". Zinthu zomwe zili m'thupi la loko sizimangotsimikizira kulimba kwa loko m'malo enaake komanso zimakhudzanso mphamvu yake yochenjeza, magwiridwe antchito achitetezo, komanso kusavuta kugwira ntchito.
Kodi nsalu yotchingira ndi maziko a maloko achitetezo m'mafakitale? Thupi la loko ndiye gawo lalikulu lomwe limateteza mphamvu zakunja ndipo limalimbana ndi kuwonongeka kwa chilengedwe. Zipangizo zosakwanira zingayambitse kuti lokoyo izimbe, isweke, komanso itaye mphamvu zotetezera, zomwe zimapangitsa kuti njira yotetezera isagwire ntchito. Zipangizo zabwino kwambiri ziyenera kukwaniritsa miyezo inayi nthawi imodzi: mphamvu yayikulu, kukana chilengedwe, kukana kutentha, komanso kulimba.
Kusanthula kwathunthu kwa zipangizo zodziwika bwino zotsekera chitetezo m'mafakitale:1. Maloko achitsulo wamba:Monga maloko opangidwa ndi mkuwa, maloko opangidwa ndi zitsulo zosapanga dzimbiri, maloko achitsulo, oyenera kugwiritsidwa ntchito m'mafakitale wamba popanda zofunikira zinazake. Ubwino wake ndi mtengo wotsika, koma kuipa kwake ndi kwakukulu. Njira yoyambira yophikira pamwamba pa maloko amenewa imayamba dzimbiri ikawonongeka ndipo imakhala yovuta kwambiri kuyisamalira.
2. Maloko apulasitiki aukadaulo:Woteteza chitetezo cha kutentha.
Mtundu uwu wa loko wa pulasitiki uli ndi mawonekedwe a kutchinjiriza, kuletsa maginito, kukana dzimbiri, komanso kuphulika. Ndi chinthu chofunikira kwambiri pakukonza magetsi ndi makina amagetsi. Zinthuzi zimapangidwa kudzera mu kulimbitsa kapangidwe kake, kusunga magwiridwe antchito apamwamba a kutchinjiriza komanso kukonza kukana kwake kukhudzana ndi kukhudzidwa, kukana dzimbiri, komanso kukana kutopa, zomwe zimatha kuthana ndi malo ovuta a mafakitale; nthawi yomweyo, kusintha kwa zinthu kumakhala kochepa komanso kosavuta, zomwe zimathandiza kuyang'anira njira ya LOTO (Lockout/Tagout).
3. Maloko a aluminiyamu:Yopepuka komanso yolimba bwino ndi dzimbiri. Ma loko a aluminiyamu ndi opepuka, osavuta kunyamula ndikuwongolera, oyenera kugwiritsidwa ntchito m'mafakitale omwe ali ndi kulemera kochepa.
4. Maloko achitsulo chosapanga dzimbiri:Yabwino kuposa maloko ena azinthu pankhani ya mphamvu ndi kukana dzimbiri. Vuto lake ndilakuti mtengo wosinthira ndi wokwera, nthawi yosinthira ndi yayitali, loko ndi yolemera, ndipo zimakhala zovuta kunyamula maloko angapo.
Kaya ndi chinthu chotani, maloko otetezera ayenera kukwaniritsa miyezo yofunika iyi:
1. Kiyi yapadera kapena yosasinthika:Loko lililonse kapena mndandanda wake uyenera kukhala ndi kiyi yapadera kapena kuphatikiza kuti munthu amene akutseka yekha ndiye angathe kutsegula.
2. Zosinthika ndi kapangidwe kokhazikika:Iyenera kukhala yosavuta kupachika ma chenjezo ndipo ikhale ndi mitundu ndi zizindikiro zoonekera bwino (nthawi zambiri zimayikidwa mitundu malinga ndi dipatimenti, mtundu wa ntchito, kapena mtundu wa mphamvu).
3. Kutsatira malamulo:Mogwirizana ndi muyezo wa "Locking/Labeling for Hazard Energy Control Methods in Mechanical Safety" wa GB/T 33579-2017.
