Managing Building Water Disruptions in a Post-COVID World: Water Quality and Safety Risk Assessment Tool for Academic Institutions and School Settings

Fluctuating building occupancy during the COVID-19 pandemic contributed to poor water quality and safety conditions in building water distribution systems (BWDSs). Natural disasters, man-made events, or academic institutional calendars (i.e., semesters or holiday breaks) can disrupt building occupant water usage, which typically increases water age within a BWDS. High water age, in turn, is known to propagate poor water quality and safety conditions, which potentially exposes building occupants to waterborne pathogens (e.g., Legionella) associated with respiratory disease or hazardous chemicals (e.g., lead). Other influencing factors are green building design and municipal water supply changes. Regardless of the cause, an increasing number of water management policies require building owners to improve building water management practices. The present study developed a Water Quality and Safety Risk Assessment (WQSRA) tool to address gaps in building water management for academic institutions and school settings. The tool is intended to assist with future implementation of water management programs as the result of pending policies for the built environment. The WQSRA was modeled after water management practices created for controlling water contaminants in healthcare facilities. Yet, a novel WQSRA tool was adapted specifically for educational settings to allow building owners to evaluate risk from water hazards to determine an appropriate level of risk mitigation measures for implementation. An exemplar WQSRA tool is presented for safety, facility, industrial hygiene, and allied professionals to address current gaps in building water management programs. Academic institutions and school settings should examine the WQSRA tool and formulate an organization-specific policy to determine implementation before, during, and after building water-disruptive events associated with natural or man-made disasters.

Minors Can Have Major Effects: Household Hurricane Preparation Insights from Alabama

While debate about large-scale climate change policy continues, household protective responses to climate-related risk are an increasingly important, potentially less contentious, tool to mitigate some climate impacts. Household actions to prepare for disasters like hurricanes are likely important for personal protection in geographically and socially vulnerable regions with less political appetite for government intervention. To understand social vulnerability in household-level hurricane preparation in this context, residents (n = 915) from the United States Gulf Coast state of Alabama were surveyed about their extreme event experiences, attitudes, and behaviors following the record-breaking 2020 hurricane season. On average, two-thirds of respondents took at least one hurricane preparedness action. Lower levels of preparedness were found for women, and higher levels for households with children, as well as changes in event-related climate change concern, personal harm, and disruption from COVID-19. Race/ethnicity, educational attainment, nor income was related to preparedness. © 2023 Taylor & Francis Group, LLC.

The role of natural hazard mitigation plans in an age of pandemics

With the onset of a pandemic, community planners need to be ready to assist communities to survive and thrive under current and future conditions. Every state and jurisdiction need a FEMA-approved hazard mitigation plan. This research explores the role of natural hazard mitigation planning before, during, and after the onset of a pandemic. A review of the 50 State Hazard Mitigation Plans (SHMPs) found 27 states identified pandemics as a hazard, but only four included mitigation actions, and none were sufficiently prepared for COVID-19. Advances in web-based tools offer the opportunity to combine the urgent need for mitigation planning strategies for the COVID-19 pandemic with a way forward for community planners as they prepare for future natural hazard events.

An overview of the impact of the COVID-19 pandemic on urban heat challenges

This study aims to present an overview of the impact of COVID-19 on urban heat challenges. First, this study developed a framework for understanding the linkages between COVID-19 and urban heat challenges. In particular, the framework considered COVID-19 pandemic in aspects of anti-pandemic measures (restriction, protection, individual consciousness) and anti-pandemic periods (lockdown and normalization), and analyzed urban heat challenges in aspects hazards, mitigation, and adaptation and hazards. Built upon this, this study collected the evidence of the impact of the COVID-19 on urban heat challenges in air quality, energy, economy, heat illnesses, and adaptation and mitigation strategies. This study will allow government authorities and experts in various fields to recognize the increasing vulnerability of entire cities to high temperatures as a result of current anti-epidemic strategies. Meanwhile, it provides a reference to the development of a robust, effective, and stable system for addressing urban heat challenges during public health events.

Occupational Risk Assessment for Flight Schools: A 3,4-Quasirung Fuzzy Multi-Criteria Decision Making-Based Approach

The concept of occupational risk assessment is related to the analysis and prioritization of the hazards arising in a production or service facility and the risks associated with these hazards;risk assessment considers occupational health and safety (OHS). Elimination or reduction to an acceptable level of analyzed risks, which is a systematic and proactive process, is then put into action. Although fuzzy logic-related decision models related to the assessment of these risks have been developed and applied a lot in the literature, there is an opportunity to develop novel occupational risk assessment models depending on the development of new fuzzy logic extensions. The 3,4-quasirung fuzzy set (3,4-QFS) is a new type of fuzzy set theory emerged as an extension of the Pythagorean fuzzy sets and Fermatean fuzzy sets. In this approach, the sum of the cube of the degree of membership and the fourth power of the degree of non-membership must be less than or equal to 1. Since this new approach has a wider space, it can express uncertain information in a more flexible and exhaustive way. This makes this type of fuzzy set applicable in addressing many problems in multi-criteria decision making (MCDM). In this study, an occupational risk assessment approach based on 3,4-quasirung fuzzy MCDM is presented. Within the scope of the study, the hazards pertaining to the flight and ground training, training management, administrative and facilities in a flight school were assessed and prioritized. The results of existing studies were tested, and we considered both Pythagorean and Fermatean fuzzy aggregation operators. In addition, by an innovative sensitivity analysis, the effect of major changes in the weight of each risk parameter on the final priority score and ranking of the hazards was evaluated. The outcomes of this study are beneficial for OHS decision-makers by highlighting the most prioritized hazards causing serious occupational accidents in flights schools as part of aviation industry. The approach can also be suggested and adapted for production and service science environments where their occupational health & safety are highly required.

COVID-19 Implications for Research and Education on Engineered Structures and Services

While there may be a tendency to characterize COVID-19 as exclu-sively a public health issue, engineered structures and services have both mitigated and exacerbated the pandemic’s march around the globe, raising questions about the role of engineering in controlling pandemics. Any attempts to answer these questions implicate not only the tools, techniques and problems which we define as within the province of engineering, but also the means by which we ar¬rive at this definition. As described here—in settings ranging from nursing homes to prisons to Brazilian favelas—the COVID-19 crisis has upended a number of foundational notions associated with the practice of hazard mitigation through the design and operation of engineered structures and services. It has revealed the need to ex¬amine the conditions and assumptions that characterize the models we construct and the data we collect. We do so through a number of case studies collected during the COVID-19 crisis, leading to im¬plications for the conduct of research and education to support not only further advances in our field but to improved prospects for im¬proved mitigation of pandemics and other hazards. © 2020, Policy Studies Organization.

Considerations Regarding the Climate Change Induced Hazards on Airports in Romania – A Case Study of Timişoara International Airport

Climate change is regarded as a global scale process in which an increase of magnitude and intensity of severe weather events is observed, thus affecting both air travel as well as airport infrastructure. Although the COVID-19 crisis has a significant negative impact on air travel and thus on the further development of airport infrastructure, the demand for air travel will continue to rise as the crisis nears the end. The aim of this paper is to analyse and highlight the climate change associated hazards for the airport infrastructure as well as for the safety of passengers and goods in the Western part of Romania, mainly Traian Vuia International Airport from Timişoara. Throughout this analysis, aviation related severe weather events, such as thunderstorms, hail events, fog, icing, squalls, low level wind shear, snow falls and heavy precipitation, which affect airport infrastructure and thus air travel, are highlighted. By analysing meteorological parameters from the time scale 1980-2010 together with climate change scenarios, and thus developing weather hazard maps, a better perspective of area-related hazards and therefore customized mitigation measures and adaptation strategies are to be developed. The implementation of modern forecasting equipment such as dual polarization Terminal Doppler Weather Radar (TDWR) is thus necessary in order to prevent loss of human lives, to reduce financial losses and to protect the airport infrastructure and the aeronautical navigation and communication facilities. Long term changes in meteorological parameters include an increase in air temperature, an increase in speed for both horizontal and vertical windshear during severe weather events, an increasing number of air mass thunderstorms and an increase of situations with limited visibility especially during the late autumn and early spring time.
