Ubufakazi bokuqhuma kwe-Shenhai
GB3836.1-2010 “Ingxenye ye-Explosive Atmospheres 1: Izisetshenziswa Ezijwayelekile Izidingo” ihlukanisa izinto zikagesi ezingaqhumi zibe izinhlobo ezimbili eziyinhloko ngokusekelwe endaweni yazo yokusetshenziswa: Amadivayisi kagesi ekilasi I kanye neClass II.
Izisetshenziswa zikagesi zeClass I
Lolu hlobo luklanyelwe ngokukhethekile ukusetshenziswa ezindaweni ezihlobene nezimayini zamalahle angaphansi komhlaba kanye nokucutshungulwa kwangaphezulu kwamalahle. Ngokuyinhloko ibhekisela kumadivayisi kagesi asebenza ezindaweni lapho kokubili i-methane nothuli lwamalahle kukhona. Indawo yokukhiqiza imayini yamalahle engaphansi komhlaba idume ngenselele, ebonakala ngokuba khona kwe ezivuthayo amagesi afana ne-methane, uthuli oluvuthayo njengomlotha wamalahle, kanye nezinkathazo ezengeziwe ezifana nomswakama, umswakama, kanye nesikhunta. Le mibandela ibeka izimfuno ezintsha eziqinile ekwakhiweni kwayo, ukukhiqiza, kanye nokusetshenziswa kwezinto zikagesi.
Izisetshenziswa zikagesi zeClass II
Lawa madivayisi abhekelela eziqhumayo izindawo zegesi ezingaphandle kwezimayini zamalahle futhi ngokuvamile zibhekisela ezintweni zikagesi ezisebenza ngaphansi kwezimo (okuhlanganisa kokubili igesi evuthayo nezindawo zothuli).
