Ukuthintela njani ukugqabhuka kothuli lomgubo
Ugqabhuko-dubulo lunokuthintelwa ukuba zombini okanye nayiphi na imiqathango yokuqhushumba kunye noMthombo wokutshisa kuyaphetshwa. Ukupheka kwindoda Inkqubo kufuneka iyilwe ukuthintela zombini iimeko ukuba zenzeke, kodwa ngenxa yobunzima bokuphelisa ngokupheleleyo imithombo yokutshisa, ukuthembela okungakumbi kufuneka kubekwe ekuthinteleni ukugxila kokuqhuma komgubo. Oku kunokufezekiswa ngokuqinisekisa ukuba i-powder kwi-concentration yomoya igcinwe ngaphantsi kwe-50% ye-Lower Explosive Limit (LEL).
Ii-LEL ezimiselweyo kuluhlu lweengubo zomgubo eziqhelekileyo zihlala phakathi kwe-20g / m3 kunye ne-70g/m3 ixhomekeke kwimichiza ethile kunye neempawu ezibonakalayo.Iyunithi yesicelo kufuneka iphawulwe ngokucacileyo ngomthamo weyunithi yokutsala kunye nenani eliphezulu kunye nomthamo o imipu yokutshiza. Ukucwangciswa kweyunithi kunye nokusetyenziswa komgubo wokugquma kufuneka kuhlolwe rhoqo ngokuchasene namaxabiso achaziweyo ukuqinisekisa ukuba ukugxila emoyeni akudluli i-10g/m3.
Ukugcinwa rhoqo kunye neshedyuli yokucoca kufuneka yaziswe ukukhusela ukuqokelela kunye nokwakhiwa kothuli. Kwimeko yezixhobo zombane , ukwakhiwa kothuli kunokubangela ukuvutha kwabo ngokugqithisa .
Ukusetyenziswa komoya ocinezelweyo okanye ibrashi eyomileyo yokucoca izinto ezichithekileyo zokucoca izixhobo kufuneka kuphetshwe. Izicoci zokufunxa eziqinileyo eziyilwe ngokufanelekileyo okanye ibrashi emanzi zezona ndlela zikhethwayo.
Ukutshaya kufuneka kuthintelwe ngokungqongqo kwaye yonke imithombo yokutshisa, efana neematshisi kunye nezinto zokukhanyisa kufuneka zingabandakanywa.
