Public services, for example Railroad service and hospital service, have carried out safety activities to provide safety service for users aiming “accident zero”. However, safety activities can’t go well in the actual enterprises. For the reason why safe activity can’t work, it is caused by the fact that employees’ motivation to safety activities decreases. However, the safe managers misunderstand it caused by a lowering of the safe consciousness of the employees and perform activity for the purpose of the improvement of the safe consciousness. Therefore, the safe activity in the actual enterprises cannot be readily activated by employees because of the gap of the recognition of the safe managers. We suggest that managers should evaluate the safety of the public service by an enhancement degree of the safety activity instead of employee’s safe consciousness in the enterprise. And, this study shows that the safe managers should expand new explanation to employees when I they teach how to do safety activities.
