Iimveliso ezichazwe njengokhuseleko lwangaphakathi zenziwe ngobunjineli ngendlela yokuba naziphi na iintlantsi zombane okanye iziphumo ezishushu eziveliswe phantsi kweemeko eziqhelekileyo okanye ezichazwe kwangaphambili zingaqhubi luqhushumbo kwiatmosfera engqongileyo., ezinokuqulatha iigesi ezinokutsha okanye eziqhumayo.
Ngokomgangatho we-GB3836.4, izixhobo ezikhuselekileyo ngaphakathi zichazwa njengezixhobo zombane apho zonke iisekethe zangaphakathi zibonwa zikhuselekile ngokwangaphakathi.
Iiyantlukwano ezingakhuselekanga ngokwendalo zidla ngokusetyenziswa kwiindawo ezingadingi milinganiselo yobungqina bokudubula..
