Okunezidingo Eziphakeme, Iphephile Ngaphakathi noma I-Flameproof

Ukuphepha kwangaphakathi nokungashi kumelela izigaba ezihlukene zobuchwepheshe bokuvikela ukuqhuma.

Isigaba esiphephile ngaphakathi siphinde sihlukaniswe ngamaleveli amathathu okuvikela: ia, ib, kanye ic, ngayinye iqondana Nezinga Lokuvikelwa Kwezisetshenziswa elihlukahlukene (I-EPL) izilinganiso. Ngokwesibonelo, izinga le-ic lokuvikela okuphephile ngaphakathi likalwe liphansi kune-flameproof d, kuyilapho izinga le-ia lokuvikela eliphephile lidlula i-flameproof d.

Ngenxa yalokho, iphephile ngaphakathi kanye nobuchwepheshe obungashi ngabunye bunikeza izici eziyingqayizivele nezinzuzo, ukuwenza afanele imikhiqizo nezinhlelo zokusebenza ezahlukahlukene.
