1) tag nrho cov ntaub ntawv kev qhia saum toj no yog rau koj siv.
2) lwm qhov tshwj xeeb yog txais tos rau kev sib tham ntxiv.
tuav
Kev tuav yog ua nyob rau hauv ib qho chaw zoo ventilated.Hnav cov khoom tiv thaiv tsim nyog.Tiv thaiv kom tsis txhob tawg ntawm cov plua plav.Ntxuav tes thiab ntsej muag kom huv si tom qab tuav.
Kev ceev faj rau kev nyab xeeb.Tsis txhob kov ntawm daim tawv nqaij thiab qhov muag.Tsis txhob tsim cov hmoov av thiab aerosols.Muab cov pa tso pa kom tsim nyog ntawm qhov chaw uas muaj hmoov av tsim.
Cia
Khaws rau hauv qhov chaw txias.Khaws lub thawv kaw kom nruj rau hauv qhov chaw qhuav thiab qhov cua zoo.Pom zoo cia kub 2 - 8 ° C
