BT4 thiab CT4 yog ob qho tib si qib qhab nia rau kev tawg-pov thawj motors, sawv cev rau qib sib txawv tawg-pov thawj raws li.
BT4 yog hais txog thaj chaw combustible gas accumululation area nyob rau hauv explosion chaw txaus ntshai thiab yog haum rau explosive gas ib puag ncig nyob rau hauv Zone 1 thiab Zone 2. CT4 yog hais txog cov combustible plua plav tsub zuj zuj nyob rau hauv lub explosion chaw txaus ntshai thiab yog haum rau cov plua plav explosive ib puag ncig nyob rau hauv Zones 20 , 21 thiab 22. Qhov sib txawv tseem ceeb yog raws li nram no: Scope ntawm daim ntawv thov: BT4 yog haum rau combustible gas ib puag ncig, thaum CT4 yog haum rau combustible plua plav puag ncig.Ib puag ncig hom: BT4 sib raug rau ib puag ncig cov pa taws kub hnyiab, thiab CT4 sib haum mus rau ib puag ncig plua plav.
Cov kev tiv thaiv kev tiv thaiv: Vim muaj cov yam ntxwv sib txawv ntawm cov pa roj thiab plua plav, cov khoom tawg-pov thawj motors muaj kev tiv thaiv sib txawv thiab kev sib khi yuav tsum nyob hauv ib puag ncig sib txawv.Daim ntawv pov thawj: BT4 thiab CT4 yog cov qhab-nees raug lees paub thoob ntiaj teb.Kev tawg-pov thawj motors yuav tsum tau txais cov ntawv pov thawj tawg-pov thawj thiab daim ntawv pov thawj siv cov cim no.
Nws yuav tsum tau muab sau tseg tias kev xaiv ntawm qhov tsim nyog explosion-proof qib thiab hom tawg-pov thawj lub cev muaj zog yuav tsum tau txiav txim raws li qhov kev ntsuam xyuas ntawm explosion txaus ntshai ntawm qhov chaw ua hauj lwm.Thaum siv, kev txhim kho kom raug, kev ua haujlwm thiab kev saib xyuas yuav tsum tau ua raws li cov cai tswj kev nyab xeeb thiab cov cai.
