Ua haujlwm raws li kev nyiam huv thiab kev nyab xeeb ntawm kev lag luam. Ntxuav tes ua ntej so thiab thaum kawg ntawm kev ua hauj lwm.
Cov cuab yeej tiv thaiv tus kheej
Qhov muag / ntsej muag tiv thaiv
Thov siv cov cuab yeej uas tau sim thiab pom zoo los ntawm cov qauv kev cai xws li NIOSH (USA) lossis EN 166 (EU) rau kev tiv thaiv qhov muag.
Tiv thaiv daim tawv nqaij
Cov hnab looj tes yuav tsum tau kuaj xyuas ua ntej siv.
Thov siv cov txheej txheem tsim nyog los tshem cov hnab looj tes (tsis txhob kov cov hnab looj tes sab nraud) thiab zam kev tiv thaiv daim tawv nqaij nrog cov khoom no
Thov tuav cov hnab looj tes tsis huv ua tib zoo raws li cov kev cai lij choj, cov cai, thiab cov cai hauv kev kuaj thiab cov txheej txheem zoo tom qab siv Thov ntxuav thiab tshuab ziab koj txhais tes
Cov hnab looj tes tiv thaiv uas tau xaiv yuav tsum ua raws li EU cov cai 89/686/EEC thiab EN 376 tus qauv.
Lub cev tiv thaiv
Xaiv cov kev tiv thaiv lub cev raws li hom, concentration, thiab kom muaj nuj nqis ntawm cov khoom phom sij, nrog rau cov chaw ua haujlwm tshwj xeeb.,
Hom khoom siv tiv thaiv yuav tsum raug xaiv raws li qhov xav tau thiab ntau ntawm cov khoom phom sij hauv ib qho chaw ua haujlwm.
Kev tiv thaiv ua pa
Tsis tas yuav tiv thaiv ua pa. Txhawm rau tiv thaiv cov plua plav puas, thov siv N95 (US) lossis P1 (EN 143) plua plav qhov ncauj qhov ntswg.
Lub tshuab ua pa thiab qhov chaw uas tau sim thiab dhau los ntawm tsoomfwv cov qauv xws li NIOSH (US) lossis CEN (EU).
