Chifukidzo cheN95 chinodiwa here?

Kana pasina mushonga wakajeka wechirwere ichi chitsva chekoronavirus, kuzvidzivirira ndicho chinhu chinonyanya kukosheswa. Masiki ndeimwe yenzira dzakananga uye dzinoshanda dzekudzivirira vanhu. Masiki anoshanda mukudzivirira madonhwe emvura uye kuderedza njodzi yehutachiona hwemhepo.

Masiki eN95 akaoma kuwana, vanhu vazhinji havakwanise. Musazvidya moyo, mamasiki eN95 haana kusiyana nemasiki ekuvhiya pakudzivirira hutachiona/furuu, zvichienderana neongororo yezvekurapa yakaburitswa mujenari reAmerican medical association musi wa3 Gunyana, 2019.

Mask yeN95 inopfuura mask yekuvhiya pakusefa, asi yakafanana nemaski yekuvhiya mukudzivirira hutachiona.

Cherechedza dhayamita yezvidimbu zvinosefetwa zvemasiki eN95 nemasiki ekuvhiya.

Masiki eN95:

Zvinoreva kuti zvidimbu zvisina mafuta (zvakaita seguruva, mhute yependi, mhute ine acid, tupukanana, nezvimwewo) zvinogona kuita kuti 95% yekuvhara.

Dust particles inogona kuva hombe kana diki, inozivikanwa parizvino sePM2.5 ndiyo dhayamita diki yeguruva, iyo inoreva dhayamita ye2.5 microns kana pasi.

Zvipembenene, zvinosanganisira chakuvhuvhu, howa, uye mabhakitiriya, zvinowanzova nedhayamita kubva pa1 kusvika ku100 microns.

Masiki:

Inovhara zvidimbu zvakakura kupfuura 4 microns mudhayamita.

Ngatitarisei kukura kwehutachiona.

Saizi dzemavhairasi anozivikanwa dzinotangira pa 0.05 microns kusvika pa 0.1 microns.

Saka, kungave nemasiki ekudzivirira utachiona eN95, kana nemasiki ekuvhiya, mukudzivirira hutachiona, hapana mubvunzo kuti kushandisa upfu hwemupunga.

Asi izvi hazvirevi kuti kupfeka chifukidzo hakushande. Chinangwa chikuru chekupfeka chifukidzo ndechekudzivirira madonhwe anotakurwa nehutachiona. Madonhwe acho anopfuura 5 microns mudhayamita, uye N95 nemasiki ekuvhiya zvinoshanda zvakanaka. Ichi ndicho chikonzero chikuru chinoita kuti pasave nemusiyano wakakosha mukudzivirira hutachiona pakati pemasiki maviri ane kushanda kwakasiyana kwazvo kwekusefa.

Asi chinonyanya kukosha ndechekuti, nekuti madonhwe emvura anogona kuvharika, mavhairasi haakwanise. Nekuda kweizvozvo, mavhairasi achiri kushanda anoungana muchikamu chemasefa chemasiki uye anogona kufemerwa panguva yekufema kakawanda kana akapfekwa kwenguva yakareba asina kuchinja.

Pamusoro pekupfeka chifukidziro chemaziso, yeuka kugeza maoko ako nguva nenguva!

Ndinotenda kuti nekuedza kwevazhinji venyanzvi, nyanzvi nevashandi vezvekurapa, zuva rekubvisa hutachiona harisi kure.
