Intii imtixaanku socday, waxa aan arkay dhimbiil weyn oo is-dhaafsigu xumaaday. Ma waxay ahayd toosh ama burbur - oo sidee baan u sheegaa faraqa?
Kala soocida wax-soo-baxa (qulqulka dusha sare ee dibadda) ee ka yimaadda burburka ( dalool gudaha ah) waa muhiim sababtoo ah tallaabada sixiddu gabi ahaanba way ka duwan tahay.
Qeexitaannada (IEC 60060-1):
• Daboolista: Ku daadanaya dusha sare ee dahaarka (dahaarka - dibeda ayaa laga yaabaa inuu jiro).
• Burburinta / Daloolin: Ku soo daaya dahaar adag ama dareere ah (gudaha - burbur joogto ah).

Geedka go'aanka:
1. Dariiqa dheecaanku ma ka muuqday dusha?
→ HAA=toosh → nadiif ah, qalalan, dib u tijaabi-
→ MAYA=wuxuu noqon karaa gudaha. Cabbir IR → haddii uu hooseeyo=burbur.
2. Soo dayntu ma ku soo noqnoqonaysay isla danab isku mid ah?
→ HAA=cilad gudaha ah (waxay ku celin doontaa).
→ MAYA=oogada random ee soo ifbaxa ( faddarayn).
Xeerka muhiimka ah ee la taaban karo:
• Flashover waa habayn tijaabo ah oo fashilantay, ee maaha qalab guul daraystay.
Burburka guduhu IS cilladda qalabka {{0} hagaajinta ama beddelka
Had iyo jeer dukumenti: korontadu markay soo baxdo, xaaladaha cimilada, wasakhowga dusha sare.
