Introduction

The 2007 propane explosion at the Little General Store in Ghent, West Virginia, highlights critical aspects of industrial safety and accident investigation. Analyzing such incidents through event and causal factors charts provides a structured approach to understanding the underlying causes and conditions that led to the disaster. This paper elaborates on constructing a comprehensive event and causal factors chart based on the U.S. Chemical Safety Board (CSB) report and discusses the potential causal factors, comparing them with the CSB’s findings. It also evaluates whether further analysis is necessary to improve safety measures and prevent future similar incidents.

Part I: Event and Causal Factors Chart

The process of creating an event and causal factors chart begins with identifying the sequence of key events leading to the explosion, along with the surrounding conditions that contributed to these events. The CSB report indicates that the explosion was precipitated by a combination of human error, equipment failure, and organizational lapses.

The initial event was the improper installation or leakage of propane lines in the store’s propane system, which may be classified as an assumed event [leakage of propane]. This leakage was likely caused by inadequate maintenance procedures or faulty installation practices, representing a condition [poor installation standards].

Subsequently, unnoticed or unaddressed propane leakages accumulated, creating an unsafe condition [hazardous vapor buildup]. Through a chain of events, the leaking vapor ignited, leading to the explosion {accident}. Critical conditions such as delayed detection, inadequate safety protocols, or lack of proper training contributed to this ignitable situation.

Further causal factors include the failure of safety devices or alarms to activate in time, which can be documented as a non-event [failure of detection systems]. The simultaneous occurrence of other unsafe practices, like storage of incompatible materials or lack of safety oversight, compounded the severity.

By referencing the chapter 7 procedures from the textbook, this chart is organized to reflect the sequence: initial condition → events (leakages, ignitions) → accident, along with conditions such as organizational shortcomings and procedural failures. The key is not to overcomplicate but to highlight significant causal pathways, including assumed events (e.g., potential overlooked maintenance issues) and non-events (failure alarms).

This chart visually maps how each event and condition interacts, allowing investigators or safety professionals to identify causal factors effectively. Computerized or color-coded charts, as suggested, facilitate clarity and emphasis on critical causal pathways.

Part II: Analysis of Causal Factors and Recommendations

The analysis of the CSB report reveals that the primary causal factors were inadequate maintenance and inspection procedures, organizational safety culture weaknesses, and equipment failures. Specifically, the report pinpointed that improper installation, poor handling of propane cylinders, inadequate safety oversight, and delayed emergency responses contributed decisively to the explosion.

Comparing these findings with my analysis, I identified similar causal factors, with a focus on organizational lapses and communication failures contributing to risk accumulation. However, my analysis highlighted additional concerns about training deficiencies among staff and maintenance personnel, which may have contributed to the oversight of potential leakages.

The differences suggest that while the CSB’s investigation was comprehensive, further analysis could explore human factors more deeply, including staff decision-making processes and safety culture. An expanded focus on organizational safety programs, employee training, and periodic safety audits could be crucial areas for future investigation.

Furthermore, a more detailed fault tree analysis could elucidate latent system weaknesses and identify specific points where failures align in causality chains. Employing techniques such as Failure Mode and Effects Analysis (FMEA) and Bowtie diagrams could enhance understanding of potential hazards, enabling proactive mitigation measures.

In conclusion, additional analysis is advisable. It should incorporate perspectives from organizational psychology and safety culture assessments to address human factors comprehensively. Interdisciplinary investigations integrating technical, procedural, and behavioral aspects will promote a more resilient safety environment, reducing the risk of future incidents.

Conclusion

Constructing an event and causal factors chart for the 2007 propane explosion at the Little General Store provides valuable insight into the incident’s causality. The comparison with the CSB report confirms key causal factors, while highlighting areas where further analysis could improve safety practices. Proactive investigation, emphasizing organizational culture and human factors, is essential for safeguarding against similar future accidents.
