Title: Comparative Analysis of Accident Causation Models in Systems Safety Engineering

Introduction

The safety of complex industrial systems relies heavily on understanding how accidents occur, which has led to the development of various models aimed at unraveling accident causation and prevention. Among these, the traditional Construction Accident Causation model and the System-Theoretic Accident Model and Processes (STAMP) stand out. This paper compares and contrasts these models, examines their features within accident management systems, and evaluates their benefits and limitations in supporting OSHA's mission to mitigate human factors contributing to accidents.

Construction Accident Causation Model vs. STAMP Model

The Construction Accident Causation model, rooted in traditional causal theories, primarily emphasizes linear causality—implying that specific unsafe acts or conditions directly cause accidents (Dekker, 2014). It assumes the existence of unsafe conditions or behaviors as the root causes, often leading to focus on individual mistakes or unsafe practices. Conversely, the STAMP model, developed by Leveson (2011), adopts a systems approach grounded in control theory. It recognizes that accidents result from complex interactions within socio-technical systems, including organizational, managerial, and technical factors.

The causation perspective differs significantly: while the traditional model attributes accidents to direct causes, STAMP emphasizes emergent system behaviors arising from control failures and inadequate safety constraints. For instance, in construction environments, linear models might focus on unsafe scaffolding, whereas STAMP considers management decisions, communication breakdowns, or inadequate safety protocols as underlying issues contributing to hazards.

Features of STAMP within Accident Causation Management Systems

The Accident Causation Management System (ACMS) integrating STAMP features involves proactive controls, feedback mechanisms, and safety constraints that influence system behaviors. In particular, features like safety controls, control structure modeling, and system-level hazard analysis are inherent within the STAMP-based ACMS (Leveson, 2011). These features allow organizations to identify systemic vulnerabilities rather than merely addressing immediate causes.

For example, an ACMS implementing STAMP might employ system modeling to understand how managerial decisions affect safety, incorporate regular feedback loops to monitor safety performance, and enforce safety constraints that prevent unsafe system states. This holistic approach enhances the capability to detect potential failures before they manifest as accidents.

Benefits and Limitations of Each Model

The traditional Construction Accident Causation model benefits from simplicity and ease of understanding, making it useful for immediate hazard identification and quick corrective actions (Dekker, 2014). However, its limitation lies in its reactive nature, often failing to address systemic root causes, and potentially neglecting interactions within complex systems.

The STAMP model's advantages include its comprehensive systems perspective, ability to model complex interactions, and focus on safety controls and feedback. It fosters proactive risk management, thereby reducing accident likelihood (Leveson, 2011). Nonetheless, STAMP can be complex to implement and requires extensive system understanding, which may demand significant resources and expertise.

The Accident Causation Management System that incorporates STAMP features offers a dynamic, systemic approach to safety management. Its limitations involve potential challenges in modeling intricate control structures and ensuring operational feasibility. Conversely, traditional models may overlook systemic issues, while STAMP's comprehensive nature demands continuous updating and system analysis (Langerweg & Esmailian, 2016).

Conclusion

In conclusion, the choice of accident causation models influences safety strategies significantly. While traditional causal models offer simplicity and rapid response capabilities, the STAMP model provides a broader, systemic understanding suited for complex environments like construction. Effectively integrating these models within OSHA's safety protocols can enhance human factors analysis, prevent accidents proactively, and foster safer workplaces.
