I-NFPA 25 yeyona migangatho ibalulekileyo yokuqinisekisa ukulungela inkqubo. Iyalela ishedyuli yokuhlolwa, ukuvavanywa, kunye nokugcinwa (ITM). Ukulandela imigaqo ye-NFPA 25 kuqinisekisa ukuba zonke izinto zokukhusela umlilo, kuquka iimpompo kunye neempompo ezimileyo, ziya kusebenza ngokuchanekileyo ngexesha likaxakeka.

Kutheni kubalulekile ukuba umbane oxhasayo wepompo yomlilo?

Umbane ophinda usetyenziswe uqinisekisa ukuba ipompo yomlilo isebenza ngexesha lokucima kombane. Umlilo unokonakalisa ngokulula igridi yombane yesakhiwo. Ijenereyitha yedizili ezinikeleyo, efana naleyo idityaniswe neI-TKFLOiinkqubo, zibonelela ngomthombo wamandla ozimeleyo, nto leyo eyenza kube yimfuneko yokhuseleko lobomi.

Inkqubo yokukhusela umlilo kufuneka ivavanywe kangaphi?

Uvavanyo lwenkqubo lulandela ishedyuli engqongqo echazwe yi-NFPA 25.

·Abasebenzi benza uhlolo olubonakalayo yonke imihla, veki nganye, nangenyanga.

·Iingcali zobugcisa zenza uvavanyo olupheleleyo lokuhamba kombane kwimpompo yomlilo minyaka le.

·Izinto eziphambili ezifana neepayipi zifuna uvavanyo lwe-hydrostatic rhoqo emva kweminyaka emihlanu.
