Incazelo yebanga ye-FFp2 mask|KENJOY

Ama-aerosol nezinhlayiya ezinhle yizingozi ezimbili zezempilo eziyingozi kakhulu endaweni yokusebenza, kodwa amehlo ethu avame ukuba nzima ukuwabona.Okulandelayo, ake sibheke ukuthi kanjaniffp2 imaskiumsebenzi.

Ukubaluleka kokuvikela ukuphefumula

Izinhlayiya eziyingozi zingase zidale umdlavuza noma zibe nemisebe;omunye umonakalo ohlelweni lokuphefumula.Amashumi eminyaka okuxhumana angaholela ekuthuthukiseni izifo ezimbi kakhulu.Okungcono kakhulu, zonke izisebenzi zibhekana nephunga elibi.Imaski yokuhlunga inikeza izinhlobo ezintathu zokuvikela kuma-aerosols anamafutha aphuma emanzini, intuthu kanye nezinhlayiya ezinhle phakathi nomsebenzi.Umsebenzi wawo wokuvikela uvumelana nezinga le-European Union EN 149. Lawa maski, aziwa nangokuthi imaski yohhafu yesihlungi sezinhlayiyana noma imaski yezinhlayiyana ezinhle, ahlukaniswa njengamabanga okuvikela e-FFP1, FFP2 kanye ne-FFP3.

Imaski ye-FFp2 isebenza kanjani?

Imaski yesihlungi sezinhlayiyana ingavimbela ngempumelelo uthuli, inkungu nentuthu.Indwangu yokuhlunga eminyene ivimbela ukudlula kwezinto eziqinile, futhi ungqimba lwangaphakathi luyi-electrostatic ukuze kuqinisekiswe ukuthi izinto eziyingozi zinamathiselwe kuzo futhi ngeke zihogelwe.Uhlelo lokuhlukanisa luqukethe amakilasi amathathu e-FFP, futhi isifinyezo esithi FFP simele "imaski yokuhlunga".Imaski yokuphefumula ivala umlomo nekhala futhi yakhiwe ngezinto zokuhlunga ezahlukahlukene kanye nemaski uqobo.Kufanele zisetshenziswe endaweni yokusebenza eyeqa umkhawulo wokuchayeka emsebenzini (OEL).Lokhu ukugcwala okuphezulu kothuli, intuthu kanye / noma ama-aerosol esiwaphefumula emoyeni futhi akulimazi impilo yethu.Uma kukhona ukwephulwa, kufanele ugqoke imaski yegesi.

Yini engavinjelwa imaski ye-FFp2?

Ngokuya ngokuvuza okuphelele nokuhlunga kwezinhlayiya ezifika ku-0.6 μ m, imaski yokuphefumula ye-FFP2 ihlinzeka ngokuvikeleka kokuphefumula kokungcola kwakho konke ukugxila.Ukuvuza okuphelele kusekelwe ekungeneni kwesisefo kanye nokuvuza endaweni yomlomo nekhala.Ngenxa yobuchwepheshe bokuhlunga obusha, ukumelana nokuphefumula kungagcinwa kusezingeni eliphansi, futhi izinhlayiya ezibambekile kusihlungi ngeke zishube ukuphefumula ngemva kokugqoka izikhathi eziningi.

Imaski yokuphefumula yezinga lokuvikela i-FFP2 ifanele izindawo zokusebenza lapho izinhlayiya eziyingozi neziguquguqukayo ziqukethwe emoyeni ophefumulayo.Amamaski anjalo okuphefumula kufanele aqukathe okungenani u-94% wezinhlayiya eziphezulu ezingu-0.6 μ m futhi angasetshenziswa ezindaweni eziphula i-OEL enezinga eliphakeme lezikhathi eziyi-10.Okufanayo kuyiqiniso ngevelu ye-TRK (i-technical reference concentration).Omaski bokuphefumula bebanga lokuvikela le-FFP2 bavame ukugqokwa ezimbonini zensimbi nezezimayini.Abasebenzi balezi zimboni bavame ukuchayeka emazingeni omoya, inkungu nentuthu, okungaholela ezifweni zokuphefumula, njengomdlavuza wamaphaphu.Okubaluleke kakhulu, basengozini enkulu yesifo sesibili nesifo sofuba esisebenzayo.

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