A Petri-net approach for firefighting force allocation analysis of fire emergency response with backups

Fire is one of the main accident scenarios occurring in chemical and process plants, and it can lead to domino effects due to thermal radiation. Emergency response is necessary to prevent fire escalation, in addition to safety barriers. In major industrial fire accidents, backup is usually required in emergency response, due to the lack of...

Association analysis of accident factors in petrochemical storage tank farms

In order to identify and clarify the association between the factors leading to accidents in a petrochemical tank area, this study analyzes investigation reports of 212 petrochemical tank farm accidents and combines this with the “association rule” mining and science related to complex networks. The main risk factors are determined and a risk...

Petri-net based cooperation modeling and time analysis of emergency response in the context of domino effect prevention in process industries

Emergency response is an important way to reduce losses after a major industrial accident occurs and mitigation measures should be arranged and analyzed in preparedness. The cooperation in emergency response actions which make up an emergency response process has a significant impact on the efficiency and success rate (or reliability) of...

Dynamic analysis of fire induced domino effects to optimize emergency response policies in the chemical and process industry

A fire accident is one the most dangerous accidents that may lead to knock-on effects, especially in the plants dealing with large quantities of hazardous substances. Different from other accidents, e.g., explosions, fires can last certain period of time and the thermal radiations emitted by them have a synergistic effect. At the same time, the...

Applying agent based modelling and simulation for domino effect assessment in the chemical industries

The propagation of accidents among process units may cause amplification of accident magnitude, resulting in a domino effect chain. Several catastrophic accidents occurred in the process and chemical industry presented these features. Hence, research efforts have been given to the analysis of the domino effects in order to enhance prevention...

Simulation analysis of the use of emergency resources during the emergency response to a major fire

During an emergency response to an accident or disaster, emergency response actions often need to use various emergency resources. The use of resources plays an important role in the successful implementation of emergency response, but there may be conflicts in the use of resources for emergency actions. According to the emergency response in...
