Yeyiphi imigangatho yeemaski zonyango? - Zhongx

Kwilizwe elihlala livela kwimpilo yezempilo, Imaski yezonyango Dlala indima ebalulekileyo ekukhuseleni zombini abaguli kunye nabasebenzi bezempilo. Kodwa ngeentlobo ngeentlobo kunye neelebheli, ukuqonda imigangatho esekwe ezi zinto zinokudideka. Musa ukoyika, abafundi abalwazi ngezempilo! Le bhlog ingena nzulu kwihlabathi lehlabathi lobuso bezonyango i-Masks i-Masks, ikuqukwa ngolwazi lokwenza ukhetho olunolwazi.

Abadlali ababalulekileyo: I-ASTM kunye ne-En

Imigangatho emibini ephambili elawula imveliso kunye nokusebenza kweemaski zonyango:

• I-ASTM (uMbutho waseMelika uVavanya kunye nezixhobo): Isetyenziswe ngokubanzi kuMntla Merika, iMigangatho ye-ASTM (njenge-ASTM F2100) ichaza iimfuno zezinto ezahlukeneyo zemaski yobuso, kubandakanya:

  • Ukusebenza kwentsholongwane
  • Ukusebenza kwempumelelo
  • Ukunganyangeki kwe-fluid: Uvavanyo lwamandla eMaski yokuxhathisa i-spashes kunye neeprayi.
  • Ingcinezelo eyahlukileyo: kuvavanya ukuphefumla kwemaski.

• I-En (iMilinganiselo yaseYurophu): UMGAQO-NKQUBO WE-Europe An 14683 hlula iimaski zonyango kwiindidi ezintathu ngokusekwe kwimpumelelo yabo yokusebenza:

  • Chwetheza i: Inika ukhuseleko olusisiseko nge-BFE ye-95%.
  • Chwetheza II: Inika ukhuseleko oluphezulu nge-BFE ye-98%.
  • Chwetheza i-Irir: eyona maski yokukhusela kakhulu, ukuhambisa ubuncinci boka we-98% kunye nokuchasana nokuphuculwa kokuchasana nolwelo.

Ukuhombisa iilebheli: Ukuqonda iZatifikethi seMask

Jonga ezi phawu ziphambili kunyango lwe-Mask Paking:

• I-ASTM F2100 Inqanaba (ukuba liyasebenza): Ibonisa inqanaba lokhuselo olunikezwe yimaski esekwe kwimigangatho ye-ASTM (E.G., i-ASTM F2100 iNqanaba 1, inqanaba 2, okanye inqanaba 3).
• Uhlobo lwe-14683 uhlobo (ukuba luyasebenza): Chonga udidi lweMaski ngokweNkqubo ye-European Clouration (E.G., en 14683 Chwetheza i, Chwetheza i-II, okanye uQeqele i-Ir.
• Ulwazi loLwazi: Jonga igama lomvelisi kunye neenkcukacha zonxibelelwano ngolwazi oluthe kratya.

Ukukhetha imaski elungileyo: Kuxhomekeke!

Eyona nto ifanelekileyo yobuso be-Mask ixhomekeke kwimeko ethile:

• Useto lomngcipheko ophantsi: Kumsebenzi wemihla ngemihla kwiindawo ezisengozini ezisengozini, imaski ene-BFE ye-95% (njenge-ASTM F2100 iNqanaba 1 okanye i-14683 Chwetheza.
• Izicwangciso zomngcipheko omkhulu: Abasebenzi bezempilo okanye abantu ababoniswe kwiindawo ezisemngciphekweni osemngciphekweni unokufuna i-Masks nge-BFE ephezulu ye-BFE kunye nokunganyangeki kwe-fluid (njenge-ASTM F2100 iNqanaba 3 okanye e-1468 yohlobo lweIr).

Khumbula: Soloko ulandela isikhokelo sempilo yendawo kunye neengcebiso ezivela kubasebenzi bezempilo malunga nokusetyenziswa kweMask.

Ngaphaya kweziseko: Iimbono ezongezelelweyo

Ngelixa imiGangatho inika isikhokelo esixabisekileyo, cinga ngezi zinto ezongezelelweyo:

• Ilungile: Imaski efanelekileyo efanelekileyo ibalulekile ekukhuseleni kakuhle. Jonga iimaski ngemitya eguqukayo okanye iziqwenga zempumlo zetywina elikhuselekileyo.
• Intuthuzelo: Imaski kufuneka ikhululeke ukuba inxibe ixesha elide. Khetha i-masks ezenziwe ngezinto zokuphefumla ezinciphisa ubunzima bokuphefumla.
• Ukuqina: Ukusetyenziswa okuphindaphindiweyo, qwalasela ii-masks ezenzelwe ukuXelwa ezininzi.

ILizwi lokugqibela: Ulwazi ngamandla

Ukuqonda iMaski eseMisitho yezeMicimbi yezonyango ukuxhobisa ukuba wenze ukhetho olunolwazi kwaye ubeke phambili impilo kunye nokhuseleko lwakho. Ngokuziqhelanisa nemilinganiselo ephambili kunye nokukhetha imaski elungileyo ngale meko, ungadlala indima ebonakalayo ekukhuseleni wena kunye nabathandekayo bakho.
