209 Countermeasures against Security and Reassurance in Waste Disposal and recycling System : Development of Security and Safety Design Analysis Method

Abstract

In recent years, occurrence of the accidents in the general waste disposal facilities is reported from many fields. Then, we surveyed the bulky waste disposal facilities, and made the accidents and troubles data base to prevent the accidents. We developed the Security and Safety Design Analysis Method built in accidents and troubles data base to find the potential risk from the design phase of the facilities. Moreover, we upgraded it so that calculating the risk from the damage situation by deciding the default value concerning the amount of damage referring to insurance might become possible. We assessed the safety of the bulky waste disposal facilities with the Security and Safety Design Analysis Method. As a result, the explosion in the ripper generated by the combustible gas such as the gas spray cans mixing is the most risky.
