Igice cyo gushungura igice cya mask (6003-2 FFP2)

Igice cyo gushungura igice cya mask nigice cyibikoresho byokwirinda byashizweho kugirango bihuze neza mumaso kandi birinde ibyuka bihumanya umwuka guhumeka nuwambaye.Ibi bikoresho birashobora kwitwa guhumeka cyangwa gushungura facepiece respirators (FFRs).

Gukoresha neza ni bumwe muburyo bwo gupima gusuzuma mask.

Uburyo bwo Kwipimisha- Gukora neza (FE)
FE ni igipimo cyibice bifatwa nibikoresho byo kuyungurura.Ipimwa no guhangana nibikoresho hamwe nubunini bwubunini buzwi, bitwarwa kumuvuduko uzwi cyangwa umuvuduko uzwi, no gupima ubunini bwibice hejuru yibikoresho, Igikombe, no munsi yibikoresho, Cdown.Ibice byinjira binyuze muyungurura ibikoresho, Pfilter, ni igipimo cyo kwibanda kumurongo wo hasi ugana hejuru, byikubye 100%.FE niyuzuza ibice byinjira: FE = 100% - Pfilter.Akayunguruzo kanyuzamo 5% by'ibice byinjira (Pfilter = 5%) bifite 95% FE.FE iterwa nibintu byinshi, harimo nibikoresho byo kuyungurura;ingano, imiterere, hamwe nuburyo bwikibazo cyibibazo, umuvuduko wikirere, ubushyuhe nubushuhe, gupakira, nibindi bintu.

Birazwi neza ko FE yibikoresho byo kuyungurura bishobora gutandukana kubice byubunini butandukanye.Ibi ni ukubera ko kuyungurura bibaho binyuze mumikorere myinshi yumubiri - kuyungurura cyangwa kuyungurura, kutagira imbaraga, gufata, gukwirakwizwa, gukurura imbaraga, hamwe no gukurura amashanyarazi, kandi imikorere yibi bikorwa iratandukanye bitewe nubunini buke.Ingano yingirakamaro kubintu byo kuyungurura bifite FE yo hasi byitwa ubunini bwinjira cyane (MPPS).Byiza, MPPS ikoreshwa mugupima imikorere ya filteri, nkuko filteri ikora kubindi bice byose bizaba byiza kuruta ibyabonetse hamwe na MPPS.MPPS iratandukanye nibikoresho byo kuyungurura n'umuvuduko wumwuka unyuze muyungurura.Ubushakashatsi bwambere bwatangaje MPPS kubuhumekero bwa 0.3 mm, ariko ubushakashatsi buherutse gukorwa bwerekanye ko MPPS iri murwego rwa 0.04–0.06.
