Cov txheej txheem tsim kev kub ntxhov txog kev tswj hwm lub zog
General kev cai
Tag nrho lub hauv paus tseem ceeb ntawm tag nrho cov kev pabcuam kev phom sij yog kev tsim qauv ntawm cov txheej txheem. Txhua lub tshuab lossis tshuab pab pawg yuav tsum txhim kho thiab sau cov ncauj lus kom ntxaws txog kev siv hluav taws xob thaum lub sijhawm tswj lossis kev tswj xyuas. Cov txheej txheem no yuav tsum tshaj tawm thiab tshaj tawm lossis tsis pub nkag rau cov neeg ua haujlwm raug tso cai rau tshuaj xyuas thiab siv.
Thaum lub chaw pov npav lossis lub Hoobkas muaj ntau lub tshuab ntawm tib yam lossis ntau dua ib qhov system lossis cov kab ntau lawm, txhua lub tshuab yuav puav leej siv tau ib txoj haujlwm.
Yog tias lub tshuab tsuas muaj ib lub zog ntawm lub zog thiab tuaj yeem qhia tau yooj yim thiab cais tawm, tsis tas yuav sau cov txheej txheem.
Cov ntsiab lus ntawm cov txheej txheem tswj
Cov txheej txheem tswj kev siv hluav taws xob tsis zoo yuav tsum qhia meej meej thiab qhia meej qhov yuav tsum ua kom zoo ntawm kev cais tawm ntawm cov tshuab. Cov txheej txheem yuav tsum muaj tag nrho cov hauv qab no;
Kev paub lub tshuab;
Ib daim npe ntawm tag nrho cov tshuab hluav taws xob uas xav tau thiab thaj chaw;
Cov txheej txheem tshwj xeeb rau kev kaw, cais tawm, thaiv, kho lossis tso tawm cov hluav taws xob khaws cia lossis tshaj plaws;
Cov kauj ruam tshwj xeeb rau kev tso thiab tshem cov lockout tagout ntaus ntawv;
Paub meej tias cov kev cais tshwj xeeb thiab kev xiam oob qhab yog tau ua tiav.
