Lock out, tag out(LOTO) yog txheej txheem kev nyab xeeb siv los xyuas kom meej tias cov cuab yeej txaus ntshai raug kaw kom raug thiab tsis tuaj yeem rov pib dua ua ntej ua tiav kev kho lossis kho cov haujlwm.Nws xav tau qhov ntawdphom sij zogyuav "tshem tawm thiab ua haujlwm tsis ua haujlwm" ua ntej pib ua haujlwm ntawm cov cuab yeej hauv nqe lus nug.Cov khoom siv hluav taws xob cais tau raug kaw thiab ib daim ntawv tso rau ntawm lub xauv uas qhia tus neeg ua haujlwm thiab yog vim li cas LOTO muab tso rau ntawm nws.Tus neeg ua haujlwm tom qab ntawd tuav tus yuam sij rau lub xauv, kom ntseeg tau tias tsuas yog lawv tuaj yeem tshem lub xauv thiab pib cov khoom siv.Qhov no tiv thaiv kev sib tsoo ntawm cov khoom siv thaum nws nyob hauv lub xeev muaj kev phom sij lossis thaum tus neeg ua haujlwm tau ntsib ncaj qha nrog nws.
Lockout-tagout yog siv thoob plaws hauv kev lag luam raws li txoj hauv kev nyab xeeb ntawm kev ua haujlwm ntawm cov khoom siv phom sij thiab raug cai los ntawm txoj cai hauv qee lub tebchaws.
Txheej txheem
Kev tshem tawm lossis ua kom muaj kev nyab xeeb ntawm cov cuab yeej siv nrog kev tshem tawm tag nrho cov khoom siv hluav taws xob thiab hu uamuab cais nyob ib leeg.Cov kauj ruam tsim nyog los cais cov cuab yeej siv feem ntau tau sau tseg hauv ib qhokev cais tawmlos yog alockout tagout txheej txheem.Txoj kev cais tawm feem ntau suav nrog cov haujlwm hauv qab no:
- Tshaj tawm kaw
- Txheeb xyuas cov khoom siv hluav taws xob
- Cais cov khoom siv hluav taws xob
- Xauv thiab tag lub zog qhov chaw
- Ua pov thawj tias kev cais cov cuab yeej siv tau zoo
Lub xauv thiab tagging ntawm lub ntsiab lus cais cia lwm tus paub tsis txhob de-isolate lub cuab yeej.Txhawm rau hais txog cov kauj ruam kawg saum toj no ntxiv rau lwm tus, tag nrho cov txheej txheem tuaj yeem raug xa mus rauxauv, tag, thiab sim(uas yog, sim qhib cov khoom siv cais kom paub meej tias nws tau de-energized thiab ua haujlwm tsis tau).
Hauv Tebchaws Meskas, lubNational Electric Codehais tias akev ruaj ntseg/kev pab cuam disconnectyuav tsum tau muab tso rau hauv qhov pom ntawm cov khoom siv tau.Qhov kev ruaj ntseg txiav tawm kom ntseeg tau tias cov cuab yeej tuaj yeem raug cais tawm thiab muaj feem tsawg dua ntawm ib tus neeg tig lub hwj chim rov qab yog tias lawv tuaj yeem pom kev ua haujlwm.Cov kev tiv thaiv kev nyab xeeb no feem ntau muaj ntau qhov chaw rau cov xauv kom ntau tshaj ib tus neeg tuaj yeem ua haujlwm ntawm cov khoom siv yam xyuam xim.
Hauv cov txheej txheem kev lag luam nws tuaj yeem nyuaj los tsim qhov chaw txaus ntshai uas tsim nyog.Piv txwv li, ib lub chaw ua khoom noj khoom haus yuav muaj cov khoom tso tawm thiab tso zis tso tsheb hlau luam thiab cov tshuab ntxhua khaub ncaws kub sib txuas, tab sis tsis nyob hauv tib chav lossis cheeb tsam ntawm lub Hoobkas.Nws yuav tsis yog qhov txawv txav uas yuav tsum tau mus xyuas ntau qhov chaw ntawm lub Hoobkas txhawm rau txhawm rau cais cov cuab yeej siv rau kev pabcuam (lub cuab yeej nws tus kheej rau lub zog, cov khoom siv sab saud, cov khoom siv hauv qab thiab chav tswj).
Cov cuab yeej siv kev nyab xeeb muab ntau yam khoom siv cais tshwj xeeb tsim kom haum rau ntau yam keyboards, li qub thiab effectors.Piv txwv li, feem ntauCircuit Court breakersmuaj txoj cai kom muaj ib lub xauv me me txuas los tiv thaiv lawv txoj haujlwm.Rau lwm cov khoom siv xws lipoblos yogrooj vagli qub, cov khoom yas uas yog haum rau cov yeeb nkab thiab tiv thaiv kev txav mus los, los yog cov khoom siv clamshell-style uas tag nrho ib puag ncig lub valve thiab tiv thaiv nws txoj kev siv.
Ib qho tshwj xeeb ntawm cov khoom siv no yog lawv cov xim ci, feem ntau yog xim liab, kom pom kev pom thiab tso cai rau cov neeg ua haujlwm nkag siab seb lub cuab yeej raug cais tawm.Tsis tas li ntawd, cov cuab yeej siv feem ntau yog qhov tsim thiab kev tsim kho kom tsis txhob raug tshem tawm nrog lub zog nruab nrab - piv txwv li, cov cuab yeej cais tsis tas yuav tawm tsam ib qhochainsaw, tab sis yog tias tus neeg teb xov tooj quab yuam tshem nws, nws yuav pom tam sim ntawd tias nws tau raug cuam tshuam nrog.
Txhawm rau tiv thaiv ib lossis ntau lub tshuab hluav taws xob hauv ib qhohluav taws xob vaj huam sib luag, lub tshuab kaw-tagout hu ua Panel Lockout tuaj yeem siv tau.Nws ua kom lub vaj huam sib luag qhov rooj xauv thiab tiv thaiv lub vaj huam sib luag ntawm lub hau kom tsis txhob raug tshem tawm.Cov hluav taws xob hluav taws xob tseem nyob hauv qhov chaw tawm thaum hluav taws xob ua haujlwm tiav.
