Ubuningi bomusi buyinto ebalulekile okufanele icatshangelwe lapho kuhlolwa ukuphepha nokusebenza kwezinto zokuvikela. Ubuningi bomusi wento bubhekisela enanini lomusi okhiqizwayo lapho into ivezwa emlilweni. Lesi yisici esibalulekile okufanele sihlolwe ngoba umusi ngesikhathi somlilo ungathinta kakhulu ukuphepha kwalabo abangaphakathi kwesakhiwo futhi uvimbele ikhono labacishi bomlilo lokuthola nokucima umlilo.
Ubuningi bentuthu yezinto zokuvikela uthuli buvame ukuhlolwa futhi bulinganiswe ngokwezindinganiso ezithile zemboni njenge-ASTM E662 noma i-UL 723. Lezi zivivinyo zihilela ukubeka izinto ngaphansi komthombo womlilo ojwayelekile kanye nokulinganisa inani lentuthu ekhiqizwayo. Imiphumela iqhathaniswa nesikali esijwayelekile ukuze kunqunywe isilinganiso sobuningi bentuthu yento.
Izinto zokuvikela ezinezinga eliphansi lomusi ziyathandwa ngoba zikhiqiza umusi omncane uma kwenzeka umlilo. Lokhu kusiza ukugcina ukubonakala futhi kwenza kube lula ukuphuma endaweni ephephile ngesikhathi sesimo esiphuthumayo somlilo. Ngaphezu kwalokho, izinto ezinezinga eliphansi lomusi ziwusizo kubacimi bomlilo ngoba bangathola futhi bacime umlilo kalula ngaphandle kokuvinjelwa umusi omningi.
Ngokuphambene nalokho, izinto zokuvikela ezinezinga eliphezulu lomusi zingaba yingozi enkulu ngesikhathi somlilo. Intuthu ejiyile evela kulezi zinto ingasitha ukubonakala, okwenza kube nzima ngabangaphakathi ukuthola izindlela zokuphuma kanye nabasebenzi bezimo eziphuthumayo ukuhamba esakhiweni. Ubuningi bomusi obuphezulu bungaholela nasekukhishweni kwamagesi anobuthi, okusongela kakhulu ukuphepha komuntu uma kwenzeka umlilo.
Uma ukhetha izinto zokuvikela ukushisa zephrojekthi yokwakha, izilinganiso zobuningi bomusi wezinketho ezitholakalayo kumele zicatshangelwe. Ngokukhetha izinto ezinobuningi bomusi obuphansi, abakhi nabaklami bangathuthukisa ukuphepha kwesakhiwo kanye nabantu abahlala kuso uma kwenzeka umlilo. Lokhu kubaluleke kakhulu ezakhiweni ezinabantu abaningi njengezibhedlela, izikole kanye nezindawo zokuhlala, lapho ukususwa kwabantu ngempumelelo kuyinto eza kuqala.
Ngaphezu kokucabangela ubuningi bomusi wokushisa, kubalulekile futhi ukuhlola ukumelana kwawo nomlilo kanye nobuthi bomusi. Izinto ezingashisi umlilo zenzelwe ukumelana nomlilo, okunikeza isikhathi esibalulekile sokuba abantu abaphakathi baphume futhi abasebenzi bezimo eziphuthumayo bafike. Ngokufanayo, izinto ezinezinga eliphansi lobuthi bomusi zikhipha amagesi ambalwa ayingozi uma zivezwa emlilweni, ngaleyo ndlela kunciphisa ingozi yokuhogela intuthu kanye nemiphumela yayo yezempilo ehambisana nayo.
Ekugcineni, ukukhetha izinto zokuvikela ezinomusi ophansi, ukumelana nomlilo okuphezulu, kanye nobuthi obuphansi bomusi kubalulekile ekwandiseni ukuphepha nokuqina kwezakhiwo. Ngokubeka lezi zakhiwo phambili, abakhi nabaklami bangasiza ekwakheni izakhiwo ezingcono ezivikela abahlali futhi zinciphise umthelela wezimo eziphuthumayo zomlilo. Lokhu, nakho, kungathuthukisa ukuthobela imithetho yokwakha, kunciphise amaphrimiyamu omshwalense, futhi kunikeze ukuthula kwengqondo okukhulu kubabambiqhaza kanye nabahlali.
