Dab tsi yog Qhov Sib Txawv Ntawm Qhov Chaw Uas Muaj Kev Nyab Xeeb?
Muaj kev pheej hmoo ntawm hluav taws kub thiab tawg yog tias muaj cov khoom siv hluav taws xob nyob hauv qhov chaw uas nws tuaj yeem cuam tshuam nrog cov kua hluav taws xob, cov pa roj, lossis cov vapors, ignitable fibers, lossis cov khoom ya.
Cov cheeb tsam txaus ntshai lossis cov cheeb tsam yog cov zoo li cov lus qhia saum toj no uas yuav muaj kev pheej hmoo los ntawm huab cua tawg. Nyob ntawm lub teb chaws, muaj ob txoj hauv kev siv los faib cov chaw muaj kev phom sij. Cov chav kawm / faib ua haujlwm yog ua haujlwm hauv North America. Cov kab ke hauv cheeb tsam tau hloov kho hauv Tebchaws Europe, North America, thiab lwm qhov hauv ntiaj teb.
Cov tshuab no yuav tsim cov qauv tsim khoom siv thiab cov txheej txheem tiv thaiv. Rau lub hom phiaj ntawm txoj kev tshawb no, peb yuav tsom mus rau thaj tsam system daim ntawv thov nyob rau hauv lub ntiaj teb no.
Zone System: Nws yog dab tsi?
Raws li Zone system, kev faib cov cheeb tsam txaus ntshai raug teeb tsa los ntawm Zone, uas tuaj yeem muab faib ntxiv rau hauv cov pa roj / vapors / pos huab thiab hmoov av. Lub kaw lus tau tawg ntxiv mus rau hauv pab pawg thiab pab pawg rau cov pa roj / plua plav cua.
