.

Result: The result showed that the highest probability of error occurrence was related to make safe workplace (evaluation phase) with 32.4 % and lowest probability of occurrence error in detection alarm (awareness phase) with 1.8 %, probability. The highest severity of error was in the evaluation phase and the lowest severity of error was in the awareness and recovery phase. Maximum risk level was related to the evaluating exit routes and selecting one route and choosy another exit route and minimum risk level was related to the four evaluation phases.
