From the standpoint of human safety, safety must be entrusted to "safety of the safety confirmation type", which is based on three principles; "Principle of safety confirmation of safe work", "Principle of unconditional safety", and "Principle of safety confirmation structure". In this report, the requisite for "Principle of safety confirmation structure" is discussed. The machinery system needs interlocking structure, i. e, the operation of a system is permitted only when a safety confirmation signal is received. In the step of generating safety information, the detector must detect not hazard but safety. In the step of transmitting the safety information, the relation between input and output must be "unate". To satisfy this, "safety" must be denoted by "active state", therefore there may be no negation operation.
