Zogulitsa:
1. Kutaya, kugwiritsa ntchito kamodzi, kupuma, kuwala komanso chilengedwe;
2. Kuthamanga kwa khutu lokwera kumathandizira ogwiritsa ntchito osiyanasiyana ndikuthandizira mbali ziwiri kumathandizira kupereka chisindikizo chotetezeka;
3. Chidutswa cha mphuno chosinthika kuti chitonthoze kwambiri;
4. Osachepera 95% kusefera koyipa motsutsana ndi zina zopanda mafuta.The kusefa bwino kwa masks a kalasi ya kn95 pazinthu zomwe zimakhala ndi aerodynamic diameter µ0.3µm ndizoposa 95%. Mlingo wa aerodynamic wa bakiteriya woyenda ndi mpweya ndi ma spores ambiri amasiyana pakati pa 0.7- 10µm, yemwenso imakhala mkati mwa chitetezo chake.
Chifukwa chake, chigoba chamtunduwu chimatha kugwiritsidwa ntchito poteteza mpweya wa zinthu zina monga kupera, kuyeretsa komanso kukonza fumbi lopangidwa ndi mchere, ufa ndi zinthu zina. Tengani gawo la mpweya wosasunthika.
Imatha kusefa ndikuyeretsa fungo loipa lomwe limapezeka mkati (kupatula mpweya wapoizoni), kuthandizira kuchepetsa kuchuluka kwa zinthu zina zosapweteka (monga nkhungu, anthrax, chifuwa chachikulu, ndi zina zambiri), koma sizingathetse matenda omwe mumakumana nawo, kudwala kapena kuphedwa kwa .

 Malangizo:
1. Izi zimaletsedwa kugwiritsidwa ntchito ndi phukusi lowonongeka;
2. Osagwiritsa ntchito mumlengalenga wokhala ndi mpweya wochepera wa 19.5%, popeza kupuma kumeneku sikupereka oxygen; Osati kugwiritsa ntchito mumlengalenga wamafuta oyipa;
3. Ngati zinthuzo zawonongeka, zadetsedwa, kapena kupuma zimayamba kukhala zovuta, siyani malo oipawo nthawi yomweyo ndikuikonzanso;
4. Izi ndizogwiritsa ntchito nthawi imodzi yokha ndipo sizingatsukidwe;
5. Izi ziyenera kusungidwa m'malo oyera, owuma komanso mpweya wabwino wochepera 80% komanso wopanda mpweya wowopsa.
