Iukuhlolwa komlilo umbiko ukwenza kucace ukuthi wethuumkhiqizo okungewona we-asbestos QF3712iqinisekisa ngokuphelele ukuvuza okungaphansi kokuvumelekile ngaphansi kwesimo sokushiswa nokupholisa phansi.Izokwengeza ububanzi bokusebenzisa ikakhulukazi ekufakweni uphawu komkhumbi.
Njengoba iukuhlolwa komliloidlulile, ingasetshenziswa kabanzi ekwakhiweni kwemikhumbi, ama-valve olwandle kanye nembonini yenjini yasolwandle ene-sealing gasket material, esebenza namafutha ahlukahlukene, igesi, amanzi kanye neminye imidiya.
Ngokushisa okuhle, ukumelana nengcindezi kanye nokuqina okuphezulu, nokuqiniswa okuhle kakhulu kokuqina nokumelana nokukhasa, iukuhlolwa komliloiwubufakazi obengeziwe bomlingiswa omuhle we-QF3712 ekwenzeni inetha lensimbi, amapuleti ensimbi athuthukisiwe amapuleti okuvala angenawo i-asbestos.
Sihlala sigxile ekuthuthukisweni kobuchwepheshe bemikhiqizo engcono nephelele, sisebenzisa ithalente nemali eyengeziwe ocwaningweni nasekuthuthukisweni njalo ngonyaka.Sizibophezele ekubeni uchwepheshe bezixazululo zokuvala uphawu kusukela ngo-1991.
