Isivivinyo sokuhlola usayizi wemaski we-FFp2|KENJOY

Imishini yokuvikela ukuphefumula ivamise ukusetshenziselwa ukuvikela abantu ezingozini zokuphefumula, okuhlanganisa izinto zamakhemikhali, zebhayoloji kanye nemisebe.Isihloko sanamuhla sikhuluma ngendlelaffp2 imaskiziyahlolwa.

Uma kungekho ukulawula kobunjiniyela nokuvikela okusebenzayo, imaski ye-ffp2 ingavimbela abasebenzi ekusebenzeni kwansuku zonke ezingozini zempilo nempilo.Uma amamaski e-ffp2 enganikeli ukuvikelwa okwanele kubasebenzisi, ingozi yokuchayeka kulezi zingozi zokuphefumula izokhula futhi iholele emiphumeleni yezempilo engemihle.Ngakho-ke, kubalulekile ukuqinisekisa ukuthi imaski ye-ffp2 inikeza ukuvikelwa okwanele kubasebenzisi.

Ukuhlolwa kokusebenza kahle kokuhlunga

Amamaski e-FFP2 ahlukaniswa njengeziphefumulo zokuhlanza umoya futhi asetshenziswa kakhulu futhi amukelwe ngabasebenzi ezimbonini ezihlukahlukene kanye nomphakathi jikelele.Lokhu kungenxa yokuthi i-ffp2 itholakala ngobukhulu obuhlukahlukene, ifanele ukuhlukahluka kobuso, kulula ukuyinakekela, inesithiyo esincane kumuntu oyigqokile, futhi inokuhlola okuphezulu kakhulu mayelana nesisindo nokulula.Abasebenzi bezempilo bayelulekwa ukuthi basebenzise imaski egunyaziwe ye-ffp2 noma ama-respirators aphezulu ukulwa nezifo ezihlukahlukene ezithathelwanayo ezitholakala emoyeni.

Amamaski e-FFp2 awakwazi ukusetshenziswa ezindaweni zamaconsi kawoyela;I-R (engamelani nowoyela ngandlela thize) kanye no-P (ukumelana nowoyela okuqinile) kusho ukuthi umshini wokuphefumula ungasetshenziswa ukuvikela kuma-aerosol angewona amafutha nanamafutha.Amagama ezinombolo 95, 99 kanye ne-100 akhombisa ukuthi ubuncane bokusefa kwesihlungi kungu-95%, 99% kanye no-99.97% ngokulandelana.

Umthelela wokuvikela we-respirator kuma-microorganisms ungahlolwa ngempumelelo ngokutadisha umphumela wokuvikela wokuphefumula wezinhlayiya ezingatheleleki ezihambisana nobukhulu bezinhlayiya ezithathelwanayo.Ngakho-ke, izinhlayiya ze-sodium chloride (NaCl) ne-dioctyl phthalate (DOP) zivame ukusetshenziswa njengama-aerosols inselele ukuze kuhlolwe umphumela wokuvikela wama-respirators.Izinhlayiya ze-NaCl zisetshenziselwa ukuhlola ukusebenza kahle kokuhlunga kwama-aerosol angewona amafutha, kuyilapho izinhlayiya ze-DOP zisetshenziselwa ukuhlola ama-aerosols anamafutha.

Njengoba izinhlayiya zingena kumshini wokuphefumula ngokuvuza kophawu lobuso kanye nezinto zokuhlunga, ukusebenza komshini wokuphefumula kuhlolwa ngokuhlolwa kokufaneleka, ukuhlolwa kokungena kanye nokuhlolwa okuphelele kokuvuza kwangaphakathi kwezifundo zabantu.Ivamise ukusetshenziselwa ukulinganisa ukufaneleka kwemaski ye-ffp2.Inhloso yokuhlolwa ukuhlola izinga lokuvikela elitholwe umshini wokuphefumula lapho kubhekwa umnikelo wazo zonke izindlela zokuvuza.Akwanele ukusebenzisa ukuhlolwa kokufaneleka noma ukuhlunga idatha ukuze uhlole ukusebenza kukonke kwesixhumi sokuphefumula.Ukuhlolwa kokuvikela ukuphefumula kuvame ukwenziwa kusetshenziswa ikhanda le-mannequin kunezifundo zabantu, kuziba izici zomuntu ezifana nobukhulu bobuso namaphethini wokuphefumula kanye namazinga okugeleza angase aphazamise ukuvikelwa okunikezwa isithwebuli sokuphefumula.

Okungenhla yisingeniso sokuhlolwa kokuhlunga kwamaski we-ffp2.Uma ufuna ukwazi okwengeziwe ngamamaski e-ffp2, sicela ukhululeke ukusithinta.
