Available in PDF, EPUB and Kindle. Book excerpt: The construction industry has historically suffered from high frequency and severity of accidents, making safety a major concern for all associated stakeholders. To improve safety performance, leading safety indicators have emerged as a more effective alternative to the traditional lagging indicators measured after the occurrence of an incident or accident. These are ex ante assessment of construction behaviors and processes to proactively predict safety breaches. Prior research has defined and assessed leading safety indicators, but has not yet sufficiently understood their actual current application either at the local and/or regional levels. To this end, this research aims to study, define, evaluate and provide guidance in relation to utilizing leading safety indicators in Tennessee. The research utilizes an interdependent research methodology. Based on a comprehensive literature review, an industry questionnaire was developed targeting construction professionals in Middle and East Tennessee. The results of the questionnaires were analyzed through different statistical analysis techniques including reliability measures, measures of central tendency and variability, correlations, normality, and comparisons of means. The results of the survey, received from professionals with collective experience of over 600 years, showed that 66.7% of the firms investigated had an instituted system of leading indicators. Firms with no use or awareness of an instituted system still applied concepts similar to leading indicators. Also, it was revealed that among the 78 indicators of the survey, only 48 were highly utilized by the responding firms. The most popular indicators - used by over 80% of respondents - were related to Housekeeping, use of Personal Protective Equipment (PPEs), and Substance Abuse Programs. On the other hand, the least popular indicators were associated with contractual safety obligations, feedback stemming from safety meetings, and perceptions and evaluations of reporting systems. Larger companies were more likely to use passive leading indicators related to policymaking and strategic programs compared to smaller companies. Pursuant to the findings of this research, it is advisable to repeat similar studies at other local and regional areas across the nation to assess similarities and differences in implementation. This will help in developing effective and efficient proactive strategies for a zero-accident construction industry.

This book was released on 2016 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Construction remains one of the top contributors for workplace injuries and fatalities in many countries. Due to the inability of lagging indicators (e.g., accident rates) to provide early warnings of accidents, the development of leading safety indicators has been a topic of increasing concern for both academics and practitioners in recent years. A review of existing leading indicators in the construction industry reveals that they have the following limitations: (1) ambiguous definitions, (2) problematic simplification process, and (3) a lack of development method. Therefore, the overarching goal of the research is to develop a set of descriptive safety leading indicators that can be used to (1) simplify complex safety phenomena, (2) measure safety performance, and (3) predict the trend in safety. To achieve the goal and address the limitations of existing construction leading indicators, this research first develops a pragmatic method for developing leading indicators, which consists of four steps: conceptualization, operationalization, indicators generation, and validation and revision. The development method provides a systematic process for developing leading indicators. In order to offer systemic insights into simplification process of complex safety realities, this research then explores the dynamics and complexity of construction safety management at the industry and project level. Eight construction safety archetypes are identified, which capture the common behaviour patterns of construction safety management. In addition, a system dynamics model is developed and simulated to monitor the dynamics of safety level at the project level. Furthermore, this research develops and tests an integrative model of safety behaviour using structural equation modelling (SEM). The results improve an understanding of safety behaviours shaping mechanisms and thus help to determine leading indicators with predictive validity. The validity of the integrative model is tested across small and large construction companies. Results suggest that the relationships among safety climate factors and safety behavior were equivalent across the two groups. Finally, a pressure-state-practice (PSP) model is develop to provide an overall framework for developing leading indicators. The safety level of a construction project is conceptualized as a high-level abstract construct that can be assessed by state indicators, pressure indicators, and practice indicators. Criterion validity (i.e., concurrent validity and predictive validity), practicability and cost-effectiveness of the leading indicators were qualitatively tested and supported by the empirical evidence collected from three construction projects. Overall, the research adds to the body of scientific knowledge of leading safety indicators. It improves the understanding of complexity and dynamics of safety management in the construction industry. In addition, the safety leading indicators developed in this paper provide the construction industry with a promising tool to measure safety performance proactively and facilitate safety assessment.

This book was released on 2015 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Safety performance in the construction industry has improved significantly since the Occupational Safety and Health Act was enacted in 1970. Despite these improvements, annual accident statistics indicate the construction industry remains one of the most dangerous for workers. However, there are some construction companies that defy these statistics and have an exemplary safety record. Many of these companies have adopted a zero-accident vision and measure their safety performance using both leading and lagging indicators. Safety performance has traditionally been measured with only lagging indicators that have included recordable injury rates, experience modification rates, days-away-restricted-transferred, among many others. Unfortunately these indicators are recorded after an accident has occurred, resulting in management only being able to take a reactive approach. Conversely, a proactive approach uses leading indicators to alert management before an accident occurs. Previous research has found thirteen leading indicators that are connected to a strong safety performance for construction projects. However, several researchers and safety management experts recommend only monitoring and measuring two to three indicators on a project due to the resources required. Determining which leading indicators to monitor can be a difficult process for management new to this proactive approach. In an effort to help the construction industry, the first phase of data collection for my dissertation benchmarked the knowledge and use of leading indicators by interviewing twenty-five small contractors. The purpose of the interview was to identify leading indicators used by each small contractor and identify challenges to implementation when an indicator was not being used. The results were analyzed to find the total percentage of use for each indicator and their relationship to the contractor's total recordable injury rates. Two leading indicators were found to be linked with a safer total recordable injury rate and both indicators included having high percentages of workers employed for more than five years. The second and third phase of data collection for my dissertation focused on large owner and contractor companies who typically have had a better safety performance in comparison to small contractors. The Delphi method was used to assemble two separate expert panels to quantify the pairwise synergistic effects among thirteen leading indicators from the perspective of an owner and a contractor. The expert panel from the perspective of the owner found the leading indicators with the greatest synergistic impact included pre-task planning, project management team safety process involvement, housekeeping program, owner safety walkthroughs, worker observation process, owner participation in worker orientation sessions, and stop work authority. The other panel from the perspective of a contractor found the indicators with most synergistic impact were pre-task planning, near-miss reporting, worker observation process, an auditing program, and project management team safety process involvement. The results from this study can serve as an aid to all management that are beginning to take a more proactive approach towards measuring and monitoring safety performance.
Download or read book Active Construction Safety Leading Indicator Data Collection and Evaluation written by Ibukun Gabriel Awolusi and published by . This book was released on 2017 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: The construction industry continues to experience an increased rate of workplace injuries and fatalities when compared to other U.S. industrial sectors. Construction workers often face safety and health risks throughout the construction process because of these dangerous working environments. Current safety practices, which are largely passive in nature, have not yielded the desired optimum results. Further improvements are necessary to enhance construction safety through the implementation of proactive safety strategies. This research seeks to evaluate how construction safety performance can be enhanced during the construction phase through the application of active construction safety leading indicators and sensing technologies. A near miss data collection and analysis framework is created and implemented for the management of safety leading indicator information. An objective evaluation of wearable technology systems for personalized construction safety monitoring is presented together with a model for integrating wearable sensors for multi-parameter safety performance monitoring. The characteristics of wearable devices and safety metrics capable of predicting safety performance and management practices are identified and analyzed. Strategies for the evaluation, selection, and implementation of vehicle intrusion sensing technologies for highway work zone safety are provided. The major contributions of this research involve the scientific data for collecting and evaluating safety leading indicators and innovative technologies, as well as an implementation guide for their application in construction. This research also provides best practices for construction management personnel that allows for the implementation of innovative safety technologies, as well as the use of collected data and information in operational procedures, safety training, and education.
Download or read book Utilizing Construction Safety Leading and Lagging Indicators to Measure Project Safety Performance written by Katelyn Versteeg and published by . This book was released on 2018 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Background Construction accounts for 22% of all workplace fatalities in Ontario (Association of Workers' Compensation Boards of Canada, 2015), although construction only accounts for 7% of Ontario's workforce (Statistics Canada, 2017a). Due to the dangers of the construction industry, safety indicators, termed leading and lagging, have been developed to measure safety performance and prevent further injury. Objective The objective of this thesis is to determine whether the relationship between safety leading and lagging indicators have predictable relationships, as they are on an industry level, when measured on a company level using company administrative data. Methods The case study involved the collection of safety indicators from 47 construction projects. An evaluation of available safety indicators was conducted and in the end 5 indicators were chosen for use in this study. These being counts of site inspections, toolbox talks, subcontractor notice of offenses, medical injuries, first aid injuries and project length. Since counts for the outcome variables exhibited an excess of zeros, the counts are assumed to be produced by two distributions, one being described by a standard Poisson process and the other a process that always produces a zero count. Four zero-inflated Poisson models were run to determine whether the leading indicator, site inspections or toolbox talks, led to a decrease in the value of the lagging indicators, medical injuries or first aid injuries. Model 1 tested the effect of site inspections on zero counts of medical injuries. Model 2 tested the effect of toolbox talks on zero counts of medical injuries. Model 3 tested the effect of site inspections on zero counts of first aid injuries. Model 4 tested the effect of toolbox talks on zero counts of first aid injuries. Results Models 1 and 2 found that number of medical injuries were not significantly related to either site inspections or toolbox talks. Models 3 and 4 found that first aid injuries were significantly related to site inspections and toolbox talks, when run independently. Yet, the estimate sizes of all four models were very small. Goodness of Fit tests were run to ensure that the sample distributions fit the hypothesized distributions of the models selected. These results showed that the lagging indicators were either not related to or had a small association to each of the leading indicators. Discussion This study showed that identifying the relationship between leading and lagging indicators may not be as easy as the theory suggests. This study had several limitations including use of administrative data, small sample size, and concern about data quality. Furthermore, theories about accident prevention and prevention research are also discussed. One theory discussed is that early accident prevention models suggest that some accidents are unpreventable. In the context of this study, it is possible that the few accidents that did occur were unpreventable in nature and could not be prevented through leading indicators. The second theory discussed was that Geoffrey Rose' Theory of Prevention suggests that concepts tested on a population level may not work on an individual level. For this study, it means that the leading and lagging indicators developed on an industry level, may not be appropriate for testing on a company level. Finally, suggestions to how the participating company could improve safety research and their safety performance were given including collecting a safety climate indicator, conducting bi-annual meetings with safety reporting personnel, improving documentation of subcontractor safety performance, and reorganizing MB's administrative data. Conclusion In conclusion, despite the fact that leading and lagging indicators have been developed on a simple assumption, there needs to be more research in order to better understand this relationship on a company level. Research needs to be completed to determine how the legislated paperwork that companies collect can be used to support injury prevention and decision making.

Download or read book Location based Leading Indicators in BIM for Construction Safety written by Xu Shen and published by . This book was released on 2017 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: The US construction industry continues to experience a high number of injuries and fatalities in comparison to other US industrial sectors (BLS 2013). Although the U.S. construction accounts for only 4% of total employment, the industry experiences a disproportionate 19% of the total fatalities experienced by the U.S. workforce (BLS 2014). An enhanced understanding of safety leading indicators for construction sites can be an influential factor in mitigating existing hazards and predicting future hazards (Hinze et al. 2013, Hinze 2006). Although construction companies in the U.S. are required by OSHA regulation to report all fatalities, injuries, and illnesses that occur on construction sites, a more concerted effort including research and implementation is required for safety leading indicators including near miss reporting and hazard identification. This research seeks to test the hypothesis that it is feasible to collect, analyze, and disseminate safety leading indicators through location-based information and visualization. Because one of the most impactful transitions in the construction industry in the past decade has been a transition to digitized construction documents with visualization of construction processes through Building Information Modeling (BIM), BIM provides a real-time visualization and communication platform for construction stakeholders (Azhar 2011, Eastman et al. 2011). Furthermore, the construction industry is transitioning from lagging or reactive safety data collection (i.e., injuries, illnesses and fatalities) to pro-active or leading indicator safety data collection (i.e., near misses and hazard identification) (Hallowell et al. 2013). This research advocates for the effective retrieval, analysis, visualization and dissemination of safety leading indicator data through created databases, algorithms and BIM functionality. Since a large majority of function components in a BIM are location-based, the outcome of this research is limited to location-based safety leading indicators (i.e., leading indicator safety data that can be assigned to a specific location). The research approach is divided into three major components: 1) near miss reporting, 2) automatic hazardous proximity zone generation, and 3) site location optimization. The framework will be evaluation in controlled laboratory settings as well as active construction sites. Throughout the research methodology, feedback and mentorship from construction engineering and management employees will be collected and integrated. This research connects the capabilities of BIM to safety data collection, storage, analysis and visualization.

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. construction industry continues to rank as one of the most dangerous work environments when compared to other industrial sectors. Construction companies are required to record and report lagging safety leading indicators including fatalities, injuries, and illnesses. Safety leading indicators provide an opportunity to identify construction site hazards and hazardous worker behavior before a fatality, injury, or illness occurs. Further improvements are also necessary for construction safety through the use of technology. The application of advanced or emerging technologies can have a significant role in enhancing construction worker safety performance. This research seeks to report and analyze safety leading indicators, specifically near misses. Furthermore, technologies capable of providing alerts in real-time to construction equipment operators and ground workers during hazardous proximity situations are reviewed. A testing method for proximity detection and alert devices for the construction environment is presented. Operator visibility, including impacts of design components, is also measured and analyzed. One major contribution of this research is the creation of a near miss reporting program ready for implementation for construction companies. Other research contributions include understanding of impacts of design on operator visibility, scientific evaluation data of proximity sensing technology, and a test method for proximity detection and alert system deployed in the construction environment. Research findings can be disseminated for improved construction worker safety education and training.

This book was released on 2013-04-17 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: These proceedings document the various presentations at the Fourth Resilience Engineering Symposium held on June 8-10, 2011, in Sophia-Antipolis, France. The Symposium gathered participants from five continents and provided them with a forum to exchange experiences and problems, and to learn about Resilience Engineering from the latest scientific achievements to recent practical applications. The First Resilience Engineering Symposium was held in Söderköping, Sweden, on October 25-29 2004. The Second Resilience Engineering Symposium was held in Juan-les-Pins, France, on November 8-10 2006, The Third Resilience Engineering Symposium was held in Juan-les-Pins, France, on October 28-30 2008. Since the first Symposium, resilience engineering has fast become recognised as a valuable complement to the established approaches to safety. Both industry and academia have recognised that resilience engineering offers valuable conceptual and practical basis that can be used to attack the problems of interconnectedness and intractability of complex socio-technical systems. The concepts and principles of resilience engineering have been tested and refined by applications in such fields as air traffic management, offshore production, patient safety, and commercial fishing. Continued work has also made it clear that resilience is neither limited to handling threats and disturbances, nor confined to situations where something can go wrong. Today, resilience is understood as the intrinsic ability of a system to adjust its functioning prior to, during, or following changes and disturbances, so that it can sustain required operations under both expected and unexpected conditions. This definition emphasizes the ability to continue functioning, rather than simply to react and recover from disturbances and the ability to deal with diverse conditions of functioning, expected as well as unexpected. For anyone who is interested in learning more about Resilience Engineering, the books published in the Ashgate Studies in Resilience Engineering provide an excellent starting point. Another sign that Resilience Engineering is coming of age is the establishment of the Resilience Engineering Association. The goal of this association is to provide a forum for coordination and exchange of experiences, by bringing together researchers and professionals working in the Resilience Engineering domain and organisations applying or willing to apply Resilience Engineering principles in their...
Download or read book Construction Safety Management Systems written by Steve Rowlinson and published by Routledge. This book was released on 2004-04-29 with total page 596 pages. Available in PDF, EPUB and Kindle. Book excerpt: The construction industry has a distressingly poor safety record, whether measured in absolute terms or alongside other industries. The level of construction safety in a country is influenced by factors such as variations in the labour forces, shifting economies, insurance rates, legal ramifications and the stage of technological development. Yet the problem is a world-wide one, and many of the ways of tackling it can be applied across countries. Effective tools include designing, preplanning, training, management commitment and the development of a safety culture. The introduction and operation of effective safety management systems represents a viable way forwards, but these systems are all too rarely implemented. How can this be done? Should we go back to prescriptive legislation? This book considers these questions by drawing together leading-edge research papers from the proceedings of an international conference conducted by a commission (W099) on Safety and Health on Construction Sites of CIB, the international council of building research organisations.

Book excerpt: Due to the injury-prone nature of the general construction industry, identifying the sector as the better performer in safety would provide insights on aspects requiring further improvement, and determining the leading indicators of injury can help companies develop preventive measures towards increasing injury reports. The two objectives were achieved into two sub-studies. Based on self-administrated survey data, comparisons on workers' demographic information, their safety perception, and safety performance were conducted between the nuclear sector and the general construction industry through Mann-Whitney test. The nuclear sectors was found to have better safety performance, and factors where the nuclear sector is the better performer were also identified. Besides, based on a 2019 incident dataset, time-dependent relationships between injuries and near miss events were developed using time series analysis. It was found that near miss and physical injuries are interacting with each other closely with lag-time of 1 or 2 weeks.

Download or read book Safety I and Safety II written by Erik Hollnagel and published by CRC Press. This book was released on 2018-04-17 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Safety has traditionally been defined as a condition where the number of adverse outcomes was as low as possible (Safety-I). From a Safety-I perspective, the purpose of safety management is to make sure that the number of accidents and incidents is kept as low as possible, or as low as is reasonably practicable. This means that safety management must start from the manifestations of the absence of safety and that - paradoxically - safety is measured by counting the number of cases where it fails rather than by the number of cases where it succeeds. This unavoidably leads to a reactive approach based on responding to what goes wrong or what is identified as a risk - as something that could go wrong. Focusing on what goes right, rather than on what goes wrong, changes the definition of safety from ’avoiding that something goes wrong’ to ’ensuring that everything goes right’. More precisely, Safety-II is the ability to succeed under varying conditions, so that the number of intended and acceptable outcomes is as high as possible. From a Safety-II perspective, the purpose of safety management is to ensure that as much as possible goes right, in the sense that everyday work achieves its objectives. This means that safety is managed by what it achieves (successes, things that go right), and that likewise it is measured by counting the number of cases where things go right. In order to do this, safety management cannot only be reactive, it must also be proactive. But it must be proactive with regard to how actions succeed, to everyday acceptable performance, rather than with regard to how they can fail, as traditional risk analysis does. This book analyses and explains the principles behind both approaches and uses this to consider the past and future of safety management practices. The analysis makes use of common examples and cases from domains such as aviation, nuclear power production, process management and health care. The final chapters explain the theoret
Download or read book Safety Metrics for the Modern Safety Professional written by C. Gary Lopez and published by CRC Press. This book was released on 2020-11-24 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book investigates the world of leading indicators and explores how they can be used effectively, providing 21st-century safety professionals with alternative metrics and guidance, which will enable them to make a difference in managing risk within an organization. The safety and health profession has been hindered by ineffective metrics for decades, with the primary metrics of choice being the OSHA incident rate and lost time accident rate. This narrow focus on what constitutes loss is not in line with the new concepts of managing the total risk that an organization faces. The book looks at indicators on a tactical level where they can be very effective in providing management with clear direction and "manageable" items they can utilize to elevate the safety efforts of an organization. It also explores the limitations of leading indicators at the strategic level and how they’re tied into the management merit review system to determine bonus and salary increase structures. It features measurements of areas of loss not usually considered by safety managers, suggests ways to use leading indicators, and promotes a departure from traditional "body count" thinking. This book will be of interest to safety professionals involved in risk management in the modern workplace.
