A fail-safe wireless power transmission system having a transmitter, a receiver, a receiver functionality monitor unit, a transmitter functionality monitor unit and at least two sensors. The transmitter has at least one low emission state, and at least one high emission state, the high emission states having higher emissions and more complex safety systems. The transmitter may be precluded from switching from a low emission state to any high emission states upon detection of a receiver control unit malfunction, a transmitter control unit malfunction, a likelihood of human-accessible emission from the system greater than a predetermined level, or an inconsistency between results arising from at least two of the sensors. Two different methods of such preclusion may be used simultaneously or consecutively to improve reliability. A transmitter control unit analyzes data from the sensors, and performs calculations to determine if and what type of preclusion is needed.
