Abstract
In response to the Editor´s suggestion, 3 states of the Lapp & Powers fault-tree model are distinguished, `good´, `failed safe´ and `failed unsafe´. Both the logical and the probability functions are given separately for both failed safe and good events as well as the probability calculations. A simplified 2-component example is also discussed to illustrate the relationship between XOR gates in fault trees and fail-safe systems and subsystems.
