Accident causation model for building construction sites
… is not adequately considered. Reports on site accidents represented nearly 50% of overall fatality cases across all industries. These statistics are indications of a continuing severity of building site accidents compared to others. Malaysian building site accidents are the results of various …

Investigating new accident causation, risk assessment, and mitigation strategy selection tools in the petroleum industry
… studies" (Fitzgerald, 2004, p. 3). Because accidents due to both human errors and electromechanical failures still occur and result in various consequences, critics have raised concerns about the petroleum industry's safety and risk mitigation credentials and question its ability to prevent …

A system theoretic safety analysis of friendly fire prevention in ground based missile systems
… used Dr. Leveson's STAMP (Systems-Theoretic Accident Model and Process) model of accident causation to analyze a friendly fire accident that occurred on 22 March 03 between a British Tornado aircraft and a US Patriot Missile battery. This causation model analyzes system constraints, control …

Safety in U.S. Navy Navigation Applying STAMP Processes to Surface Ship Collisions
The collisions and accidents occurring throughout the U.S. Navy surface fleet warranted the appointment of a 34-personnel review team to analyze the three ship collisions and one grounding in 2017. These accidents resulted in 17 U.S. Navy sailors' deaths and damage to the operational ships. There …

Systems theoretic accident analysis of an offshore supply vessel collision
This thesis uses Dr. Leveson's Systems-Theoretic Accident Model and Process (STAMP) model of accident causation to analyze a collision in late July 2014 between two Offshore Supply Vessels equipped with software-intensive Dynamic Positioning Systems. The Causal Analysis based on STAMP (CAST) is …

Systems thinking applied to automation and workplace safety
… analysis methodology based on a new model of accident causation called Systems-Theoretic Accident Model and Processes (STAMP), with the traditional assessments recommended by industry standards for analyzing safety risks in modern manufacturing workplaces that are increasingly incorporating …

An investigation into the accident causal influence of construction project features
… has triggered studies into construction accident causation which have emphasised the need to pay attention to underlying accident causal factors which emanate from the pre-construction stage in order to have sustained improvement in H&S. Construction project features (CPFs), such as …

Assessing the Effectiveness of Traffic Police in Preventing Road Accidents in Tanzania
… of Traffic Police in preventing road accidents in Tanzania. The study was based on various theories including system, accident causation, risk homeostasis and goals freedom alertness theories. The study aimed at outlining the roles of Traffic Police in preventing road accidents in …

Climate change and road freight safety: impacts and opportunities
… the current patterns in weather related freight accidents is produced, and existing studies on accident causation are elaborated upon to arrive at relationships between key meteorological parameters and freight accident rates. These relationships are extrapolated onto various climate scenarios …

A framework for dynamic safety and risk management modeling in complex engineering systems
… (PRA) rely on a chain-of-event paradigm of accident causation. Event-based techniques have some limitations for the study of modem engineering systems. Specifically, they are not suited to handle complex software-intensive systems, complex human-machine interactions, and systems-of-systems …

The identification and measurement of safety management systems : towards a behavioural response approach
… latent conditions and active errors in terms of accident causation. The author intends to show that human error is a consequence, not a cause, and that is shaped and provoked by upstream workplace and organisational factors. Only by understanding the context that caused the error can we hope to …

Systems-theoretic safety analyses extended for coordination
… gap by extending STAMP (Systems-Theoretic Accident Model and Processes)-based analysis methods STPA (System-Theoretic Process Analysis) and CAST (Causal Analysis based on STAMP). This thesis contributes to knowledge by introducing: 1) a coordination framework for use in analysis, 2) …

Using STPA to inform developmental product testing
… traditional reductionist approaches that treat accident causation only as a linear chain of events or probabilistic occurrence of simultaneous component failures (including human error). While systems-based and complete, STPA could benefit from additional guidance, particularly in the …

Constructing trust in acute inpatient mental healthcare facilities : the role of physical, social and symbolic environments of care in supporting therapeutic safety
… into James Reason’s (1995) Swiss Cheese Model of Accident Causation to illustrate how environments emphasizing surveillance and technical safety do not create therapeutically safe environments but introduce latent error, leading to patient harms such as violence, seclusion and sanctuary harm. Four …

Understanding government and railroad strategy for crude oil transportation in North America
… safety is of particular concern, CAST, an accident investigation tool built on the STAMP accident causation model, is used to study the safety control structure of the Canadian railway industry that existed prior to the Lac-Megantic accident. This research describes how environmental …

A new approach to modeling aviation accidents
… GA flights have a much higher fatal accident rate than commercial operations. Recent estimates by the Federal Aviation Administration (FAA) showed that the GA fatal accident rate has remained relatively unchanged between 2010 and 2015, with 1566 fatal accidents accounting for 2650 …
