Namuhla, sizoqhubeka nokuhlola kwethu ukukhanya kwezimboni, egxile ezintweni zokukhanyisa ezingaqhumi.
Ukuhlukaniswa ngezigaba
Izibani ezingaqhumisi ziyahlukahluka kuye ngezinyathelo zokuvikela ezisetshenziswayo. Lezi zisukela kokungashi, ukwanda kokuphepha, ukuphepha kwangaphakathi, ecindezelwe, zimboziwe, ukucwiliswa ngamafutha, hlanziwe, uhlobo n, ezinhlotsheni ezikhethekile. Kulesi seshini, sizongena ekusetshenzisweni kakhulu okungashi kanye ukwanda kokuphepha izigaba.
Uhlobo lwe-Flameproof
Kuboniswa incwadi “d,” angashi uhlobo luhlanganisa izingxenye zezindlu ezingase zikhiqize izinhlansi noma ama-arcs ngesikhathi sokusebenza okuvamile endaweni ebiyelwe ngokuqinile evimbela ukuqhuma.. Lesi sikhwama simelana nokucindezela kokuqhuma kwangaphakathi ngaphandle kokulimala, ukuqinisekisa ukuthi amalangabi namagesi adlula ezikhaleni zawo alahlekelwa amandla, ngaleyo ndlela kugwenywe ukuthungela amagesi angaphandle.
Uhlobo Lokuphepha Olunyusiwe
Imakwe ngencwadi “e,” uhlobo lokuphepha olwandisiwe luqinisekisa ukuthi okokusebenza azenzi izinhlansi noma ama-arcs ngaphansi kwezimo ezijwayelekile. Idizayini yayo iqiniswa nakakhulu ukuze ivikeleke, ukuqinisa ukuthembeka nokuphepha okuphelele kwezinto zokusebenza.
