the effects of extreme winds on atmospheric storage tanks
Reliability Engineering & System Safety, 2020Co-Authors: Oscar Ramirez J Olivar, Santiago Zuluaga Mayorga, Felipe Munoz Giraldo, Mauricio Sanchezsilva, Jeanpaul Pinelli, Ernesto SalzanoAbstract:Abstract The impact of hurricanes, tornados, severe storms, or more in general extreme winds can damage the equipment of industrial plants, leading to the loss of containment of hazardous material from the damaged structures, which in turn can pollute or evolve to catastrophic scenarios involving fires or explosions. This type of Accidents is known as Natech (Natural hazard triggering Technological Accident). Among natural events, extreme winds can affect atmospheric storage tanks, due to their intrinsic structural vulnerability combined with their capacity to store large quantities of hazardous material, often flammable. In this work, the authors have evaluated the vulnerability (and the fragility) function for storage tanks impacted by extreme wind loads for the aims of industrial risk assessment., taking into account either the structural damage or the loss of containment. Monte Carlo simulations method estimates the uncertainty associated with the random behavior of the parameters of the model. A case study for a vertical storage tank shows that non-negligible risk occurs for filling level higher than 15%. The study offers guidance on how to include the wind-related phenomena as entry parameters for industrial risk assessment in geographical areas prone to strong winds.

Technological Accident community class action litigation and scientific damage assessment a case study of court ordered research
Sociological Spectrum, 1993Co-Authors: Steven J Picou, Donald D RosebrookAbstract:A train carrying various regulated hazardous and toxic chemical commodities derailed in Livingston, Louisiana, on September 28, 1982. The resulting fires and explosions necessitated a 14‐day evacuation of over 3,000 residents and precipitated a class‐action lawsuit against the railroad. The court ordered, on its behalf, an independent assessment of the ecological, physical, economic, sociological, and psychological damages resulting from the derailment and subsequent events. These assessments, delayed by legal appeals, began in December 1983 and continued until February 1985. The ecological damage assessment was accomplished by general and quality assurance audits of the records of the railroad's cleanup contractor with the cooperation of the railroad and its contractor and by reviewing the records of the Louisiana health and environmental agencies. The economic, sociological, and psychological damage assessments were accomplished using a common survey instrument administered to a statistically chosen sam...

the social psychological impacts of a Technological Accident collective stress and perceived health risks
Journal of Hazardous Materials, 1991Co-Authors: Duane A Gill, Steven J PicouAbstract:Abstract Technological Accidents pose a threat to community structure and the social psychological wellbeing of community residents. This research provides an evaluation of the impact of a major train derailment and toxic spill in Livingston, Louisiana, a rural community in the United States. The nature, direction and magnitude of this impact are assessed through data collected under a court-order and introduced as evidence in class-action litigation. A disaster impact assessment design was developed and data were collected 20 months after the Accident. Findings for the residents of Livingston reveal that victims closer to the impact site, members of families who are evacuated for longer time periods and members of families who were separated at the time of the Accident experienced the most collective stress and manifested strongest concerns about risks to their health. Many of the community residents wanted to move because they were upset with the source of the Accident and they perceived that they had “increased risks of getting cancer” and feared that their “drinking water was contaminated”. The social-psychological impact of this Technological Accident varied in terms of disaster demographics, providing one basis for mitigation and the allocation of compensation through a court settlement.

The Williams pipeline disaster: A controlled study of a Technological Accident
Journal of Traumatic Stress, 1991Co-Authors: George M. Realmuto, Nancy Wagner, John BartholowAbstract:This study reports the results of a neighborhood interview for Post-Traumatic Stress Disorder (PTSD) symptoms 13 months after a manmade Technological disaster. Interviews with 24 victims found 3 who satisfied DSM-III-R criteria for PTSD. However, a low community response rate of 58%, resident relocation and other factors raise the possibility of sampling bias and results should be considered cautiously. Victims experiencing PTSD symptoms were more likely to be female, older, and having a history of psychiatric treatment. Some PTSD symptoms were more frequent than others, especially the avoidance symptoms of amnesia, diminished interest and detachment, which had a sensitivity of 63% and a specificity of 100%. One particular arousal symptom, sleep difficulty, was generally confined to female victims. The study corroborates the findings of larger disasters regarding the importance of certain characteristics of individuals that place them at greater risk for psychological morbidity following a disaster. Further studies are needed to define the unique characteristics of circumscribed disasters, such as social, religious or geographical parameters that may mitigate or compound the effect of a disaster.
