Kev Nyab Xeeb Hluav Taws Xob hauv Chaw Ua Haujlwm

Kev Nyab Xeeb Hluav Taws Xob hauv Chaw Ua Haujlwm

Ua ntej, kuv nkag siab cov ntsiab lus tseem ceeb ntawm NFPA 70E txog kev siv hluav taws xob nyab xeeb: thaum muaj Shock Hazard, txoj hauv kev zoo tshaj plaws los xyuas kom muaj kev nyab xeeb yog kaw tag nrho cov khoom siv hluav taws xob thiabLockout tagout
Txhawm rau tsim "kev nyab xeeb ua haujlwm hluav taws xob"

Qhov Kev Nyab Xeeb Ua Haujlwm Hluav Taws Xob yog dab tsi?

Ib lub xeev uas cov khoom siv hluav taws xob lossis cov khoom siv hluav taws xob tau raug txiav tawm ntawm 10 qhov chaw, kuaj xyuas qhov tsis muaj qhov hluav taws xob, thiab, yog tias tsim nyog, ib ntus hauv av rau kev tiv thaiv cov neeg ua haujlwm.

Txhawm rau kom muaj kev nyab xeeb ntawm cov khoom siv hluav taws xob kuaj lossis kev saib xyuas kev ua haujlwm, nws yog txoj hauv kev zoo tshaj plaws los txiav tawm lub zog hluav taws xob, tab sis peb yuav tsum tau ua ntau yam haujlwm hauv kev ua neej nyob, thiab thaum lub zog tsis ua haujlwm yuav ua rau poob ntau dua. ;Cov xwm txheej tshwj xeeb no tau piav qhia hauv tus qauv, uas peb yuav tham tom qab.

Thaum EHS cov neeg ua haujlwm tsim kev nyab xeeb hluav taws xob lossis cov txheej txheem ua haujlwm nyob,
Txoj cai ua raws li yuav tsum yog "tawm lub hwj chim tawm haujlwm ua thawj qhov kev xaiv".
NFPA 70E, ARTICLE 110 General Requirements for Electrical Safety-related Work Practices, muab cov lus qhia txog yuav tsim cov txheej txheem kev nyab xeeb hluav taws xob li cas.Cov ncauj lus kom ntxaws yog tsim rau cov txheej txheem kev nyab xeeb hluav taws xob, cov kev xav tau ntawm kev cob qhia, lub luag haujlwm ntawm cov chaw ua haujlwm thiab cov neeg ua haujlwm cog lus, cov khoom siv ntsuas hluav taws xob thiab cov chaw ua haujlwm, thiab cov khoom tiv thaiv cov dej xau.

Nov yog qhov kuv pom nthuav:

Tus Neeg Tsim Nyog (feem ntau hu ua Tus Neeg Tso Cai) tsis tsim nyog tom qab kev cob qhia yooj yim, vim tus neeg yuav tsum tau sim lossis kho cov cuab yeej siv nyob thiab tuaj yeem nkag mus rau thaj tsam Restited Approach Boundary, uas muaj feem ntau ntawm kev sib cuag nrog Arc. Flash.Yog li tus qauv muaj cov ncauj lus kom ntxaws txog cov neeg ua haujlwm tsim nyog.
Tus neeg tsim nyog yuav tsum muaj peev xwm txiav txim seb qhov chaw nyob yog dab tsi thiab qhov voltage yog dab tsi, thiab nkag siab txog qhov kev nyab xeeb ntawm qhov hluav taws xob no, thiab xaiv cov qib tsim nyog ntawm PPE raws li.Kuv txoj kev nkag siab yooj yim yog tias ntxiv rau kev tau txais daim ntawv tso cai hluav taws xob, lawv yuav tsum tau txais kev cob qhia tshwj xeeb los ntawm lub Hoobkas thiab dhau qhov kev xeem, thiab cov neeg ua haujlwm zoo li no yuav tsum tau rov ntsuas dua txhua xyoo.
Thaum kuaj xyuas qhov chaw nyob uas yuav dhau 50V, qhov kev ncaj ncees ntawm cov cuab yeej ntsuas yuav tsum tau txiav txim siab ntawm qhov paub qhov hluav taws xob ua ntej thiab tom qab txhua qhov kev sim.
