2 Cov xwm txheej rau kev nyab xeeb cia, suav nrog txhua yam tsis sib xws
Khaws rau qhov chaw txias. Khaws lub thawv kaw nruj nreem hauv qhov chaw qhuav thiab qhov cua zoo.

Cov Khoom Tiv Thaiv Tus Kheej

Kev tiv thaiv qhov muag/ntsej muag
Cov tsom iav kev nyab xeeb nrog cov thaiv sab nrauv ua raws li EN166 Siv cov cuab yeej rau kev tiv thaiv qhov muag kuaj thiab pom zoo raws li tsoomfwv cov qauv tsim nyog xws li NIOSH (Asmeskas) lossis EN 166 (EU).

Kev tiv thaiv ntawm daim tawv nqaij
Kov nrog hnab looj tes. Cov hnab looj tes yuav tsum tau tshuaj xyuas ua ntej siv. Siv cov txheej txheem tshem cov hnab looj tes kom raug (tsis kov lub hnab looj tes sab nrauv) kom tsis txhob tawv nqaij nrog cov khoom no. Muab pov tseg cov hnab looj tes uas muaj kab mob sib kis tom qab siv raws li txoj cai lij choj thiab kev coj ua hauv chaw sim zoo. Ntxuav thiab qhuav tes. Cov hnab looj tes tiv thaiv uas tau xaiv yuav tsum ua kom tau raws li qhov tshwj xeeb ntawm Kev Cai (EU) 2016/425 thiab tus qauv EN 374 tau los ntawm nws.

Kev Tiv Thaiv Lub Cev
Cov khaub ncaws tsis pom kev, Yam khoom siv tiv thaiv yuav tsum raug xaiv raws li qhov siab thiab ntau npaum li cas ntawm cov khoom phom sij ntawm qhov chaw ua haujlwm tshwj xeeb.

Kev tiv thaiv kev ua pa
Rau qhov cuam tshuam tsis zoo siv hom P95 (Asmeskas) lossis hom P1 (EU EN 143) lub tshuab nqus pa. Rau kev tiv thaiv qib siab dua siv hom OV/AG/P99 (Asmeskas) lossis hom ABEK-P2 (EU EN 143) lub tshuab nqus pa. Siv lub tshuab ua pa thiab cov khoom ntsuas thiab pom zoo raws li tsoomfwv cov qauv tsim nyog xws li NIOSH (Asmeskas) lossis CEN (EU).
