Yiziphi izindinganiso zamaski wezokwelapha? - I-Zhongxing

Emhlabeni ophakade wokuvela kwezempilo, imaski yezokwelapha dlala indima ebalulekile ekuvikeleni zombili iziguli nabasebenzi bezempilo. Kepha ngezinhlobo ezahlukahlukene namalebula, ukuqonda izindinganiso ngemuva kwale maski kungadida. Ungesabi, abafundi abaqonda ngempilo! Le bhulogi ishonela ijule emhlabathini wemaski yobuso bezokwelapha, ikuhlomisela ngolwazi lokwenza izinqumo ezinolwazi.

Abadlali ababalulekile: ASTM NE-EN EN

Izindinganiso ezimbili zamabanga aphansi zilawula ukukhiqizwa kanye nokusebenza kwamaski wezokwelapha:

• I-ASTM (umphakathi waseMelika wokuhlola nezinto zokwakha): Kusetshenziswe kakhulu eNyakatho Melika, amazinga e-ASTM (njenge-ASTM F2100) Chaza izidingo zezinto ezahlukahlukene zemaski yobuso bezokwelapha, kufaka phakathi:

  • Ukusebenza kwegciwane le-bactration (BFE): kukala amandla kaMask okuvimba amagciwane.
  • Ukusebenza kahle kwe-Filtration (PFE): Kukala amandla kaMask okuvimba izinhlayiya.
  • Ukumelana ngoketshezi: Kuvivinya amandla kaMaski wokumelana nama-splashes namaphethelo.
  • Ingcindezi ehlukile: ihlola ukuphefumula imaskhi.

• En (izinkambiso zaseYurophu): I-European Standard En 14683 ihlukanisa imaski yobuso yezokwelashwa ibe yizinhlobo ezintathu ngokuya ngokusebenza kwazo kwe-filltration:

  • Thayipha I: Inikeza ukuvikelwa okuyisisekelo nge-BFE ephansi engu-95%.
  • Uhlobo II: Inikeza ukuvikelwa okuphezulu nge-BFE ephansi engu-98%.
  • Thayipha i-IIR: Imaski yokuvikelwa kakhulu, enikeza i-BFE ephansi engu-98% futhi ithuthukisiwe ukumelana namanzi.

Ukuhumusha amalebula: Ukuqonda okufundwayo kwemaski

Bheka lezi zimpawu ezibalulekile ekuphangelweni kobuso bezokwelapha:

• I-ASTM F2100 Level (uma ikhona): Ibonisa izinga lokuvikelwa elinikezwe yimaski ngokususelwa kumazinga we-ASTM (E.G., ASTM F2100 Level 1, Izinga 2, noma Izinga 3).
• Uhlobo lwe-14683 (uma lukhona): Khomba uhlobo lwemaski ngokohlelo lokuhlukaniswa kwe-European (E.G., NEJ 14683 Type I, uhlobo II, noma thayipha iir).
• Imininingwane Yomkhiqizi: Bheka igama lomenzi nemininingwane yokuxhumana ukuthola eminye imininingwane.

Ukukhetha imaski efanele: Kuya!

Imaski ephezulu yezokwelapha efanelekile incike esimweni esithile:

• Izilungiselelo ezinobungozi obuphansi: Ngemisebenzi yansuku zonke ezindaweni ezisengozini ephansi, imaski eno-bfe okungenani ka-95% (njenge-ASTM F2100 LEVEL 1 noma i-EN 14683 Uhlobo lwe-I) lunganele.
• Izilungiselelo ezinobungozi obukhulu: Abasebenzi bezokunakekelwa kwezempilo noma abantu abavulelwe izimo ezisengozini enkulu bangadinga imaski ene-bfe ephakeme kanye nokumelana koketshezi (njenge-ASTM F2100 LEVEL 3 noma i-EN 14683 THELO IIR).

Khumbula: Njalo landela imihlahlandlela yezempilo yendawo nezincomo ezivela kochwepheshe bezokunakekelwa kwempilo mayelana nokusetshenziswa kwama-mask.

Ngaphesheya kwezisekelo: Ukucatshangelwa okwengeziwe

Ngenkathi amazinga anikela ngohlaka olubalulekile, cabanga ngalezi ezingeziwe:

• Kufanelekile: Imaski efanelekile ibalulekile ekuvikelweni kahle. Funa imaski ngemichilo eguqukayo noma izingcezu zempumulo zophawu oluphephile.
• Induduzo: Imaski kufanele ibe ntofontofo ukugqoka isikhathi eside. Khetha imaski eyenziwe ngezinto eziphefumulelwe eziphefumulayo ezinciphisa ubunzima bokuphefumula.
• Ukuqina: Ukusetshenziswa okuphindaphindwayo, cabanga imaski eyenzelwe ukugqokwa okuningi.

Igama lokugcina: Ulwazi lungamandla

Ukuqonda imaski yobuso bezokwelapha okukunika amandla okwenzayo ukwenza izinqumo ezinolwazi futhi ubeke phambili impilo yakho nokuphepha. Ngokujwayela amazinga asemqoka futhi ukhethe imaski efanelekile ngalesi simo, ungadlala indima ebonakalayo ekuvikeleni wena kanye nabathandekayo bakho.
