Gulu la Zida Zamagetsi Zowonetsera Kuphulika

GB3836.1-2010 “Chigawo cha Explosive Atmospheres 1: Zida Zonse Zofunikira” amayika zida zamagetsi zomwe sizingaphulike mu mitundu iwiri yoyambirira kutengera momwe amagwiritsidwira ntchito: Zida zamagetsi za Class I ndi Class II.

Zida zamagetsi za Class I

Mtundu uwu wapangidwa makamaka kuti ugwiritsidwe ntchito m'madera okhudzana ndi migodi ya malasha yapansi panthaka komanso kukonza malo a malasha. Amatanthawuza makamaka zida zamagetsi zomwe zimagwira ntchito m'malo omwe methane ndi fumbi la malasha zilipo. Malo opangira migodi ya malasha mobisa ndizovuta kwambiri, yodziwika ndi kukhalapo kwa kuyaka mpweya ngati methane, fumbi loyaka ngati phulusa la malasha, ndi zovuta zina monga chinyezi, chinyezi, ndi nkhungu. Mikhalidwe imeneyi imabweretsa zovuta zatsopano pamapangidwe, kupanga, ndi kugwiritsa ntchito zida zamagetsi.

Zida Zamagetsi za Class II

Zida izi zimathandizira zophulika malo a gasi kunja kwa migodi ya malasha ndipo nthawi zambiri amatanthauza zida zamagetsi zomwe zimagwira ntchito pamtunda (kuphatikizapo mpweya woyaka ndi fumbi).
