| Summary: | 碩士 === 國立交通大學 === 工學院產業安全與防災學程 === 106 === So far there are no systematic investigation methods for accident investigation regarding chemical tank truck traffic accidents. This study utilizes a systematic accident investigation method to develop a survey method for traffic accidents involving chemical tankers. This study divides accident investigation procedure into four steps: organizing the investigation team, evidence collection, accident cause analysis, and improvement suggestions. The key part of the on-site evidence collection is based on the 4Ps evidence collection model proposed by the US OHSA that combined with the accident site survey method mentioned in the current domestic road traffic accident handling regulations. This results in a revised form for assisting in on-site chemical tank truck traffic accident investigation. For the accident cause analysis part, we adapt the accident cause analysis model used by BP and incorporate the causes of road traffic accident investigation report along with researcher's experience in the emergency response work of chemical disasters.
Accident investigators can use this revised cause analysis table to match the evidence on the spot to find out the all possible root causes effectively. The proposed method is verified by two historical chemical tank truck accidents and results show that the proposed method has a certain degree of feasibility and is easier for implementation. However, the identified causes of the accident summarized by the proposed method are a list of the possible root causes. It is necessary to understand the actual implementation status of the company policy and management to determine the actual causes of the accident.
