In this study, the target safety level of egress from fire room was discussed. The calculation method defined in Ministry of Construction's Notification 1441 (2000) was analyzed by using the method of reliability engineering. The limit state function was selected by the difference between nominal margin of egress safety and actual, stochastic margin of egress safety. By examining the safety level of limit state function, the target safety index implied in the verification method is clarified for typical office building layout. The results show that (1) the implied safety index is in the range of 1 to 3 depending on the method of smoke control and floor area. (2) In comparison with type A variability (fuel and occupant load), the effect of type B uncertainties (prediction error) is not neeligible. (3) Possible combination of partial safety factors are proposed by 0.2, 2-6, 0.9 for fuel load density, escape start time and smoke filling time for typical office buildings with single side corridor.
