Taw qhia:
Kev tiv thaiv kev tawg yog ib qho tseem ceeb hauv kev ua kom muaj kev nyab xeeb hauv ib puag ncig uas muaj cov pa hluav taws xob, vapors, plua plav, lossis dej ua rau muaj kev phom sij, tshwj xeeb tshaj yog hauv cov cuab yeej ntsuas kev lag luam. Cov kev ntsuas no tau sib txuas lus los ntawm cov cim tshwj xeeb thiab cov lej uas qhia txog qib kev tiv thaiv los ntawm cov cuab yeej tiv thaiv kev pheej hmoo ntawm kev tawg.
Hauv tsab xov xwm no, peb yuav delve rau hauv lub cheeb tsam ntawm kev tiv thaiv kev tawg, npog cov cim, lub ntsiab lus, ntau theem, thiab kev faib tawm cuam tshuam nrog cov qauv kev nyab xeeb tseem ceeb no.
Cov cim tiv thaiv tawg:
Ex Symbol: Cov cim Ex ua cov qauv tseem ceeb ntawm kev tiv thaiv kev tawg, ua raws li tsab ntawv qhia txog yam tshwj xeeb ntawm cov khoom phom sij. Piv txwv li, Ex d qhia txog kev tiv thaiv kev tawg los ntawm cov pa taws, vapors, lossis kua.
Gases thiab Vapors:
Ex ia: Intrinsically Safe rau gases, denoting cov cuab yeej tsim los tiv thaiv kev tso tawm ntawm lub zog txaus rau ignite flammable gases.
Ex d: Flameproof, qhia cov cuab yeej muaj peev xwm tiv taus qhov tawg hauv qhov tsis pub nws khiav mus rau qhov chaw nyob ib puag ncig.
Plua plav:
Ex tb: Plua plav-tiv thaiv, haum rau ib puag ncig nrog cov plua plav combustible. Qhov 't' txhais tau hais tias kev tiv thaiv tawm tsam cov plua plav tawm, thiab 'b' txhais tau tias tsim nyog rau cov huab cua hauv plua plav.
Explosion Protection Levels:
Zone System (ATEX):
Zone 0: Nruam qhov chaw ntawm cov nplaim taws.
Zone 1: Flammable cua yuav tshwm sim hauv kev ua haujlwm ib txwm muaj.
Thaj Chaw 2: Cov huab cua kub tsis zoo yuav tshwm sim hauv kev ua haujlwm ib txwm muaj tab sis yuav nyob mus ib ntus.
Gas Groups (IECEx):
IIA, IIB, IIC: cais cov pa roj thiab vapors raws li lawv cov khoom siv hluav taws xob. IIC suav nrog cov khoom muaj phom sij tshaj plaws.
Chav Kawm Kub Kub:
T1 txog T6: Qhia qhov kub siab tshaj plaws ntawm cov khoom siv thaum lub sijhawm ua haujlwm. T1 sawv cev rau qhov qis tshaj, thiab T6 qhov siab tshaj plaws, chav kawm kub.
Nkag siab cov cim:
Piv txwv li: Ex d IIC T6 Gb:
Ex d: Flameproof tiv thaiv
IIC: Gas Group qhia txog qib siab tshaj plaws ntawm kev phom sij
T6: Chav ntsuas kub, qhia txog qhov siab tshaj plaws ntawm qhov chaw
Gb: Cov cuab yeej tsim nyog siv rau hauv Cheeb Tsam 1 (Gas)
Dust Example: Ex tb IIIC T85degree Db:
Ex tb: Dust-protected
IIIC: Plua plav Group qhia txog cov hmoov av uas muaj kev phom sij tshaj plaws
T85 degree: qhov kub thiab txias siab tshaj plaws
Db: Cov cuab yeej tsim nyog siv rau hauv Cheeb Tsam 21 (Dust)

Kev nkag siab zoo ntawm kev tiv thaiv kev tawg yog qhov tseem ceeb rau kev tswj xyuas qhov chaw ua haujlwm ruaj ntseg hauv kev lag luam uas muaj kev pheej hmoo ntawm huab cua tawg. Txawm hais tias cuam tshuam nrog cov pa roj, vapors, lossis plua plav, ua raws li cov qauv tsim nyog ua kom cov cuab yeej tsim thiab ntawv pov thawj los txo qhov kev pheej hmoo ntawm hluav taws kub thiab tawg.
Rau MACSENSOR sensors siv rau lub sijhawm tawg lossis tawg, peb tau txheeb xyuas daim ntawv pov thawj. Tiv tauj pebntawm noyog xav paub ntxiv.
