Ikirangantego cya GKF cyiza cyane cyohereza ikirere gikoresha igishushanyo mbonera cyikoranabuhanga kugirango igabanye ikirere ryumvikane neza, imiterere yisanduku iroroshye kandi yizewe, igikonoshwa gikozwe mubyuma byujuje ubuziranenge, irangi ryo hejuru cyangwa gutera plastike.1.Umwuka mwiza mu cyambu gitanga ikirere gifite gahunda nziza yo gutembera mu kirere, kugira ngo ugere ku ntego yo kugabanya ahantu hapfuye ahantu hasukuye, kugira ngo habeho isuku, ni ukuvugurura n’icyumba gishya gisukuye mu nzego zose nkigikoresho cyifashishwa mu kuyungurura , yashyizwe mucyumba gisukuye gisenge nahandi hantu.Ibiranga:
reka ifite uruhande rwimbere no hejuru, kandi umunwa wa flange ufite kare na kare.
2. Rimwe na rimwe, iyo icyumba gisukuye kigarukira ku burebure bwubwubatsi cyangwa kigomba kwemeza igishushanyo mbonera, icyambu cya HEPA cyungurura ikirere gishobora gutoranywa.
3. Urashobora gushyirwaho ukurikije ibisabwa byabakoresha bigenga valve hamwe nubushuhe.
Ikigega cya DOP cyamazi meza yohereza ikirere nicyuma giciriritse cya filteri ya HEPA ikoreshwa muri sisitemu yo gutanga ikirere.Ikigamijwe ni ukubona igitutu cyiza mbere yuko umwuka unyura muyungurura HEPA, kugirango akayunguruzo ka HEPA gashobora gukoreshwa neza.
