Inherently safe design is becoming more and more important in the environment marked by the increasing failure costs such as costs incurred by recalls and accident handling in various industrial fields. International standards define acceptable risks and tolerable risks based on the principle of "ALARP (As Low as Reasonably Practicable)". However, pursuing the inherently safe design affects judgments made based on the ALARP principle and makes risk management more difficult when other viewpoints including CSR (Corporate Social Responsibility), compliance and brand management are involved. This paper presents a framework for preventive safety management as a measure to counter the above difficulties in risk management. This paper also presents a practical usage of the quantification technique for the qualitative risk assessment, proposed in other paper, and an example of application of such practical usage to risk communication between the management side and the engineers side to improve the qualitative risk assessment.
