2. Cov Chaw Tseem Ceeb Hauv Cov Vaj Huam Sib Luag Hluav Taws Xob Uas Yuav Tsum Tau Nruab Ib Lub Hloov Pauv Kev Rho Khoom

Kev teeb tsa cov qhov hloov pauv cais tawm zoo pab txhim kho kev nyab xeeb thiab kev yooj yim hauv cov kab ke hluav taws xob.

Ib qho chaw teeb tsa feem ntau yogpawg thawj coj faib khoom tseem ceebKev muab lub qhov hloov cais tawm ntawm qhov chaw muab hluav taws xob nkag los tso cai rau cov neeg ua haujlwm txiav hluav taws xob rau tag nrho lub vaj huam sib luag thaum xav tau kev saib xyuas lossis kaw thaum muaj xwm txheej ceev.

Lwm qhov chaw ib txwm muaj yog nyob hauvcov vaj huam sib luag faib khoomuas muab hluav taws xob rau ntau thaj chaw ntawm lub tsev lossis chaw ua haujlwm. Qhov kev teeb tsa no tso cai rau cov kws kho tshuab cais cov ntu tshwj xeeb ntawm lub kaw lus yam tsis tas kaw tag nrho lub network hluav taws xob.

In cov txee tswj kev lag luam, cov qhov hloov cais feem ntau raug teeb tsa rau sab nraud ntawm lub qhov rooj txee. Qhov kev npaj no tso cai rau cov neeg teb xov tooj txiav lub zog ua ntej qhib lub txee, txo qhov kev pheej hmoo ntawm kev raug rau cov khoom siv hluav taws xob uas muaj sia nyob.

Cov tshuab fais fab thaub qab, xws li kev teeb tsa lub tshuab hluav taws xob lossis cov tshuab hloov pauv tsis siv neeg, kuj tseem yuav suav nrog cov hloov pauv cais tawm kom ntseeg tau tias muaj kev pabcuam thiab kev sim cov khoom siv kom muaj kev nyab xeeb.

3. Cov txiaj ntsig kev nyab xeeb ntawm kev siv lub pob hloov cais khoom thaum lub sijhawm txij nkawm thiab thaum muaj xwm txheej ceev

Cov haujlwm kho hluav taws xob muaj kev pheej hmoo loj heev rau kev nyab xeeb, tshwj xeeb tshaj yog thaum cuam tshuam nrog cov kab ke uas muaj hluav taws xob ntau lossis cov kab ke uas muaj hluav taws xob ntau. Kev siv hluav taws xob tsis raug cai thaum lub sijhawm kho tuaj yeem ua rau raug mob hnyav, ua rau cov khoom siv puas tsuaj, lossis ua rau lub sijhawm ua haujlwm tsis ua haujlwm.

Txhim kho ib qhoKev Hloov Pauv Rho Tawmpab txo cov kev pheej hmoo no los ntawm kev muab ib qho chaw txiav tawm ntawm lub zog fais fab thiab lub zog hluav taws xob. Qhov no ua kom cov neeg ua haujlwm kho tuaj yeem ua haujlwm tau zoo ntawm cov khoom siv hluav taws xob tom qab lub qhov hloov tau raug kaw.

Muaj ntau lub qhov hloov pauv cais tawm kuj txhawb nqaKev kaw/tagout (LOTO)cov txheej txheem. Qhov no tso cai rau cov kws kho tshuab xauv lub qhov hloov rau hauv qhov chaw OFF thiab muab cov ntawv ceeb toom lo rau, tiv thaiv kev rov txuas dua yam tsis tau tso cai lossis tsis txhob txwm thaum lub sijhawm ua haujlwm txij nkawm.

Thaum muaj xwm txheej ceev, lub peev xwm los cais hluav taws xob sai sai kuj tseem ceeb heev. Cov neeg ua haujlwm tuaj yeem txiav cov khoom siv sai sai kom tiv thaiv kev puas tsuaj ntxiv lossis txo cov kev phom sij xws li kub dhau, hluav taws xob tsis ua haujlwm, lossis kev pheej hmoo hluav taws.
