Ingabe ukhona umehluko phakathi kwamaski avamile alahlwayo kanye namaski ezokwelapha alahlwayo | JINHAOCHENG

Okokuqala,imaski yezokwelaphaAmamaski ezokwelapha avame kakhulu amamaski angalukiwe angasetshenziswa, amamaski e-gauze kanye namamaski alwa namagciwane.

1. Imaski engalukiwe elahlwayo enezendlalelo ezingaphezu kwezintathu ingahlukanisa amabhaktheriya nothuli, futhi iphephile futhi ithembekile ukuyisebenzisa kanye, ngaphandle kwengozi yokutheleleka kwesibili.

2. Ama-gauze masks uhlobo lwama-masks abelokhu esetshenziswa ngaso sonke isikhathi. Ama-Miao cloth masks asetshenziswa kabanzi emkhakheni wezokwelapha kanye nocwaningo.

3. Amamaski okulwa namagciwane enziwa kakhulu ngendwangu engalukiwe enesendlalelo sesihlungi phakathi. Ngokuvamile, isendlalelo sesihlungi senziwe ngendwangu yokufutha encibilikisiwe. Sinomsebenzi wokubulala amagciwane kanye nokubulala amagciwane.

4. Eqinisweni, izifihla-buso ezivamile zingaphansi kwezifihla-buso zezokwelapha kuphela.

Imayelana kakhulu nemisebenzi kanye nezikhathi zokusetshenziswa. Isikhathi samanje sokungcoliswa okukhulu komoya okulethwe umphakathi wezimboni senza ukuthuthukiswa kwamaski kube insimu eyingqayizivele. Ngokwezimo ezifanele kanye nezidingo zomsebenzisi zokuhlukaniswa kwensimu kuzoqhubeka nokuthuthuka. Ngakho-ke, ngokwezokwelapha noma okuvamile, umehluko ungaba isitayela, ungaba ukunemba kokuhlunga, ungaba osebenzayo, ungaba induduzo yokuphefumula.

Uma kwenzeka ukuqubuka kweCoronavirus okusha kulo nyaka, thenga okuningiimaski yobuso.

Kunomehluko omkhulu phakathi kwamaski namakhono awo okuzivikela

Ingabe ukhona umehluko phakathi kwamaski avamile alahlwayo kanye namaski ezokwelapha alahlwayo?

Amamaski avamile alahlwayo kanye namamaski ezokwelapha ajwayelekile kanye namamaski okuhlinzwa kanye namamaski okuvikela ezokwelapha

Amamaski okuvikela ezokwelapha: afanele abasebenzi bezokwelapha kanye nabasebenzi abahlobene nawo ukuvikela ezifweni ezithathelwanayo zokuphefumula emoyeni ezinezinga eliphezulu lokuvikela.

Amamaski okuhlinzwa: isivikelo esiyisisekelo sabasebenzi bezokwelapha noma abahlobene, kanye nesivikelo ekusabalaleni kwegazi, uketshezi lomzimba kanye nokuchitheka ngesikhathi sezinqubo zokuhlasela;

Imaski yezokwelapha evamile: umphumela wokuvikela ngokumelene namagciwane abangela izifo awunembile. Ingasetshenziswa ekunakekelweni kwezempilo kanye kuphela ngaphansi kwendawo evamile, noma ukuvimba noma ukuvikela izinhlayiya ngaphandle kwamagciwane abangela izifo njengempova.

Eqinisweni, lezi yizindinganiso zikazwelonke, azikho ngokungahleliwe

(1) Imaski yokuvikela yezokwelapha

Ngokuhambisana ne-gb19083-2003 "Izidingo Zobuchwepheshe Zamamaski Okuvikela Ezokwelapha", izinkomba zobuchwepheshe ezibalulekile zifaka phakathi ukusebenza kahle kokuhlunga kwezinhlayiya okungenamafutha kanye nokumelana nokuhamba komoya:

1. Ukusebenza kahle kokuhlunga: Ukusebenza kahle kokuhlunga kwe-aerodynamics ububanzi obuphakathi (0.24±0.06) m sodium chloride aerosol bekungaphansi kuka-95% ngaphansi kwesimo sezinga lokugeleza komoya (85±2)L/min, okungukuthi, kuhambisana ne-N95(noma i-FFP2) kanye namazinga angaphezulu.

2. Ukumelana nokumunca: Ukumelana nokumunca akumele kudlule u-343.2Pa ngaphansi kwezimo zesilinganiso sokugeleza ezingenhla.

(2) Imaski yokuhlinzwa

Ngokuhambisana ne-YY 0469-2004 Izidingo Zobuchwepheshe Zamamaski Okuhlinzwa, izinkomba zobuchwepheshe ezibalulekile zifaka phakathi ukusebenza kahle kokuhlunga, ukusebenza kahle kokuhlunga kwamagciwane kanye nokumelana nokuphefumula:

1. Ukusebenza kahle kokuhlunga: Ukusebenza kahle kokuhlunga kwe-aerosol ye-aerodynamic median (0.24±0.06) m sodium chloride kwakungaphansi kuka-30% ngaphansi kwesimo sezinga lokugeleza komoya (30±2)L/min;

2. Ukusebenza kahle kokuhlunga kwamagciwane: Ngaphansi kwezimo ezibekiwe, ukusebenza kahle kokuhlunga kwe-staphylococcus aureus aerosol enobubanzi obumaphakathi bezinhlayiya ezingu-(3±0.3) m kwakungaphansi kuka-95%;

3. Ukumelana nokuphefumula: Ngaphansi kwesimo sokugeleza kokusebenza kahle kokuhlunga, ukumelana kokuphefumula akufanele kudlule i-49Pa kanti ukumelana kokuphefumula akufanele kudlule i-29.4Pa.

(3) Imaski yezokwelapha evamile

Ngokuhambisana nezindinganiso zomkhiqizo ezibhalisiwe ezifanele (i-YZB), izidingo zokusebenza kahle kokuhlunga kwezinhlayiya namabhaktheriya ngokuvamile azikho, noma izidingo zokusebenza kahle kokuhlunga kwezinhlayiya namabhaktheriya ziphansi kunezo zemaski yokuhlinzwa yezokwelapha kanye nemaski yokuzivikela.

(4) Imaski evamile elahlwayo

Amamaski ajwayelekile e-gauze awaphathwa njengezinto zokwelapha
