Kev Tiv Thaiv Kev Nyab Xeeb
Kev ceev faj rau kev nyab xeeb
TSIS qhib nplaim taws. Kaw qhov system, plua plav tawg-pov thawj cov khoom siv hluav taws xob thiab teeb pom kev zoo. Tiv thaiv kom tsis txhob muaj plua plav. Tuav nyob rau hauv qhov chaw zoo ventilated. Hnav khaub ncaws tiv thaiv kom haum. Tsis txhob kov ntawm daim tawv nqaij thiab qhov muag. Tsis txhob tsim cov hmoov av thiab aerosols. Siv cov cuab yeej uas tsis muaj teeb meem. Tiv thaiv hluav taws los ntawm electrostatic tawm chav.
