Forkliftssiv hauvChemical Industries, Zog tsim, Dej pov tseg, Gas mov, Txau painting, Refineries,thiab lwm yam. Yuav tsum muaj cov ntaub ntawv pov thawj tawg. Yog li yuav ua li cas txheeb xyuas qib hauv ntau qhov chaw?
Kev faib cheeb tsam
Zone 1:
Ib qho chaw nyob rau hauv qhov chaw tawg uas muaj qhov sib xyaw nrog huab cua ntawm cov khoom siv hluav taws xob hauv daim ntawv ntawm cov pa roj, vapor lossis pos huab yuav tshwm sim nyob rau hauv ib txwm ua haujlwm qee zaus.
Zone 2:
Ib qho chaw nyob rau hauv qhov chaw tawg uas muaj qhov sib xyaw nrog huab cua ntawm cov khoom siv hluav taws xob hauv daim ntawv ntawm cov pa roj, vapor lossis pos huab tsis zoo li tshwm sim hauv kev ua haujlwm ib txwm muaj tab sis yog tias nws tshwm sim yuav nyob rau lub sijhawm luv xwb.
Zone 21:
Ib qho chaw uas muaj huab cua tawg nyob rau hauv daim ntawv ntawm ib tug huab ntawm combustible plua plav nyob rau hauv cov huab cua yuav tshwm sim nyob rau hauv ib txwm ua hauj lwm qee zaus.
Zone 22:
Ib qho chaw nyob rau hauv cov huab cua tawg nyob rau hauv daim ntawv ntawm ib tug huab ntawm combustible plua plav nyob rau hauv cov huab cua tsis zoo li yuav tshwm sim nyob rau hauv ib txwm ua hauj lwm tab sis yog hais tias nws tshwm sim yuav nyob twj ywm rau ib tug luv luv lub sij hawm xwb.
Cov lus txhais rau Zone 0 thiab Zone 20 tsis tau qhia tias cov tsheb thauj khoom tsis raug tso cai ua haujlwm hauv thaj chaw zoo li no.
Gas pawg thiab Chav Kawm Kub
Tag nrho cov tsheb thauj khoom yuav raug muab los ua kom haum rau Gas pab pawg IIA thiab IIB thiab nrog rau qhov kub thiab txias rau chav T.3 200 degree , tshwj tsis yog tias tau teev tseg.
Chav Kawm Kub:
T1 Qhov kub siab tshaj plaws saum npoo 450 degree
T2 Qhov kub siab tshaj plaws ntawm 300 degree
T3 Qhov kub siab tshaj plaws saum npoo 200 degree
T4 Qhov kub siab tshaj plaws saum npoo 135 degree
T5 Qhov kub siab tshaj plaws saum npoo 100 degree
Lus Cim: Cov khoom siv tsuas yog T5 yog Carbon disulfide. T6 (85 degree tsis siv tau).
Gas Pawg:
IIA Surface kev lag luam, sawv cev roj Propane thiab Acetone.
IIC Surface kev lag luam, sawv cev roj hydrogen.
Cov ntaub ntawv ntxiv ntawm qhov flashpoint, vapor ceev, flammability ntau, nws pib-ignition kub thiab roj pab pawg neeg ntawm cov ntaub ntawv muaj peev xwm nrhiav tau nyob rau hauv cov seem uas muaj feem ntawm Suav standard GB3836.
