Txog cov xwm txheej thiab cov xwm txheej ceeb toom ntsig txog LOTO (Lockout-Tagout)

I. Kev Lag Luam Fais Fab (Feem Ntau Yuav Tsis quav ntsej txog "Cov Nqi seem")
Case: Kev Tuag Los Ntawm Hluav Taws Xob Thaum Lub Sijhawm Kho Chaw Hloov Khoom
Cov Txheej Txheem: Cov neeg ua haujlwm txij nkawm tau ua kev txij nkawm rau lub txee capacitor hluav taws xob siab. Lawv tsuas yog txiav lub qhov hloov tab sis tsis tau tso tawm lossis xauv nws.
Lub capacitor khaws cia high voltage, thiab thaum kov, tus neeg raug kev txom nyem hluav taws xob thiab tuag.
Kev Ua Txhaum Cai Tseem Ceeb:
Tsis ua tiav kev siv LOTO kev cais hluav taws xob
Ua tsis tau tso tawm cov nqi seem
Tsis ua tiav kev sim rau lub zog thiab xauv
Ceeb Toom:
Rau cov khoom siv fais fab, LOTO yuav tsum tau ua raws li nram no: Tua fais fab → Sim hluav taws xob → Tso tawm → Hauv av → Xauv thiab tshaj tawm cov cim ceeb toom.
II. Kev Lag Luam Khoom Noj/Dej Haus (Muaj Xwm Txheej Tshwm Sim Ntau Zaus Thaum Lub Sijhawm Ntxuav Thiab Hloov Khoom)
Cov Ntaub Ntawv: Kev Sib Tsoo Tes Ntawm Tes Taub Hauv Lub Tshuab Sib Tov Khoom Ntawm Lub Hoobkas Ua Dej Haus
Txheej Txheem: Cov neeg ua haujlwm tab tom ntxuav lub tshuab sib tov thaum lawv tsis tau kaw lossis xauv nws. Lawv ncaj qha ncav tes mus ntxuav.
Muaj ib tug neeg nias lub pob pib tsis raug, thiab lawv txhais tes tau daig rau hauv lub tshuab sib tov, ua rau raug mob hnyav thiab txiav tes txiav taw.
Qhov Teeb Meem Tseem Ceeb:
Tsis muaj kev tiv thaiv ntawm cov nyees khawm pib/nres ntawm cov khoom siv
Kev ntxuav ≠ nres lub tshuab; LOTO yuav tsum tau ua tiav
Ceeb Toom:
Rau cov khoom siv ua zaub mov xws li cov khoom sib tov, cov khoom txiav, cov khoom xa khoom, thiab cov khoom siv ntxuav, yog tias tes yuav tsum nkag mus rau hauv cov khoom siv, nws yuav tsum tau xauv.
III. Kev Lag Luam Ntawv/Kev Luam Ntawv (Cov Rollers thiab Siv Cov Khoom Siv Uas Txaus Ntshai Tshaj Plaws)
Rooj plaub: Kev tuag los ntawm kev raug mob ntawm cov menyuam hauv Hoobkas ntawv
Cov Txheej Txheem: Cov neeg ua haujlwm tau tuav cov ntawv uas daig thiab tsis tau siv LOTO. Lawv nthuav lawv lub cev mus rau hauv cov menyuam.
Ib tug npoj yaig ua haujlwm tau qhib lub qhov hluav taws xob, thiab tus neeg ntawd txhais tes raug tsoo, ua rau raug mob hnyav thiab txiav nws txhais tes.
Kev Ua Txhaum Cai Tseem Ceeb:
Tsis muaj kev rho tawm zog
Tsis muaj lus ceeb toom lossis kev sib txuas lus
Ceeb Toom:
Cov dov, siv sia, thiab cov tshuab rub hauv kev lag luam ntawv, luam ntawv, thiab textile yog LOTO qhov kub.
IV. Kev Kho Dej Phwj Tuaj/Kev Tiv Thaiv Ib Puag Ncig Kev Lag Luam (Cov Li Qub, Twj Tso Kua Dej, Lub Pas Dej Ua Si Cov Xwm Txheej Feem Ntau)
Cov Ntaub Ntawv: Kev Poob Dej Thiab Kev Raug Mob Thaum Lub Sijhawm Kho Lub Twj Tso Kua Dej
Cov Txheej Txheem: Thaum lub sijhawm saib xyuas lub twj tso kua dej phwj tuaj, lub qhov dej nkag tsis tau kaw thiab nws tsis tau xauv.
Cov kav dej tam sim ntawd puv nkaus, thiab tus neeg ua haujlwm raug dej ntws mus rau hauv pas dej. Tib lub sijhawm ntawd, lub twj tso kua mis tau pib ua haujlwm tsis tau xav txog.
Qhov Teeb Meem Tseem Ceeb:
Lub zog kua tsis sib cais
Tsis muaj LOTO ntawm cov valve
Ceeb Toom:
Rau cov kav dej, cov qhov dej, cov twj tso kua mis, thiab cov pas dej ua ke hauv kev kho dej, dej phwj tuaj, thiab kev tiv thaiv ib puag ncig, txhua yam yuav tsum tau xauv kom tiv thaiv cov kua dej rov qab thiab cov khoom siv pib ua haujlwm sai.
V. Kev Lag Luam Mining/Metallurgical (Kub Kub, Siab Siab, Khoom Siv Hnyav)
Rooj Plaub: Kev Tuag Los Ntawm Kev Raug Rub Los Ntawm Lub Tshuab Nqa Khoom Thaum Lub Sijhawm Kho Tshuab Siv
Txheej Txheem: Txoj siv sia tau tig mus, thiab tus neeg ua haujlwm txij nkawm tsis tau xauv lossis khi nws. Lawv sawv ntawm txoj siv sia kom kho.
Lub siv conveyor pib ua haujlwm tam sim ntawd, thiab tus neeg ua haujlwm raug rub mus rau hauv cov rollers thiab tuag.
Qhov Teeb Meem Tseem Ceeb:
Tsis muaj LOTO
Tsis muaj kev txheeb xyuas lub zog
Ceeb Toom:
Rau cov conveyors, scrapers, crushers, thiab kilns hauv kev lag luam mining, metallurgy, thiab kev tsim kho, LOTO nruj yuav tsum tau ua.
VI. Kev Lag Luam Tshuab Tsim Kho/Engineering (Feem ntau hla cov kauj ruam thaum lub sijhawm txij nkawm thiab kho)
Cov Ntaub Ntawv: Kev Raug Mob Los Ntawm Kev Raug Tsoo Hauv Kev Kho Excavator
Txheej Txheem: Thaum lub sijhawm saib xyuas lub caj npab hydraulic, tus neeg ua haujlwm tsis tau txhawb nqa, txo qhov siab, lossis xauv nws.
Lub hydraulic circuit depressurized, thiab lub caj npab cia li poob, ua rau tuag.
Qhov Teeb Meem Tseem Ceeb:
Tsis muaj kev tso tawm ntawm lub zog hydraulic
Tsis muaj kev xauv khoom siv
Ceeb Toom:
Rau cov conveyors, scrapers, crushers, thiab kilns hauv kev lag luam mining, metallurgy, thiab kev tsim kho, LOTO nruj yuav tsum tau ua.
