The main hazard for ground facilities during launch vehicle (LV) nominal flight is in the separated parts (SP) impact areas. SP impact areas are specially allocated to ensure safety along LV ground tracks. The paper deals with a risk assessment model for facilities in the SP impact area, which takes into account the uncertainty of the altitude of SP initial destruction. Practical use of the developed model for determining hazardous area, within which the risks for people exceed the allowable level, is described. We show that the obtained hazardous area allows more adequate determination of the size of allocated area for SP impact.
