An interpretable clustering approach to safety climate analysis: Examining driver group distinctions.

The transportation industry, particularly the trucking sector, is prone to workplace accidents and fatalities. Accidents involving large trucks accounted for a considerable percentage of overall traffic fatalities. Recognizing the crucial role of safety climate in accident prevention, researchers have sought to understand its factors and measure its impact within organizations.

The impact of COVID-19 pandemic on construction safety in China and the U.S.: A comparative study.

Many studies indicated that the COVID-19 pandemic had significant impacts on construction safety. However, the studies had differing views on whether the pandemic increased or decreased construction safety performance. Furthermore, past studies did not adopt a comparative time series approach to evaluate the impact of the pandemic on construction safety.

Prioritization of industry level interventions to improve implementation of design for safety regulations.

Introduction: Many countries introduced mandatory Design for Safety (DfS) or Prevention through Design (PtD) requirements to reduce construction accident rates. However, there is a knowledge gap on the relative importance of industry level interventions to improve the implementation of DfS regulations. Thus, this study aims to identify and prioritize a set of industry level interventions to help regulators and industry associations understand the industry's perceptions and improve the implementation of mandatory DfS.

Management of safe distancing on construction sites during COVID-19: A smart real-time monitoring system.

The outbreak of Coronavirus Disease 2019 (COVID-19) poses a great threat to the world. One mandatory and efficient measure to prevent the spread of COVID-19 on construction sites is to ensure safe distancing during workers' daily activities. However, manual monitoring of safe distancing during construction activities can be toilsome and inconsistent.

A mixed-methods approach to examining safety climate among truck drivers.

The purpose of the current study was to use a mixed-methods approach to understanding safety climate and the strategies to improve safety climate among truck drivers. Using both survey (N = 7246) and interview (N = 18) responses provided by truck drivers regarding key safety climate items, the current study identified a number of positive and negative policies, procedures and practices that truck drivers perceived as the determinants of whether their organizations are committed to the promotion of safety at work. Item response theory (IRT) analyses were conducted to identify discrimination parameters indicating which safety climate items were most sensitive to the safety climate level.

Experimental validation of an energy balance approach for design of horizontal lifeline systems.

The energy balance approach is one of the design approaches approved in fall protection standards Z359.6, Z259.16 and SS 607 to ensure that horizontal lifeline systems (HLLSs) are adequately designed.

Validation of the energy balance approach for design of vertical lifeline systems.

To ensure that vertical lifeline systems (VLLSs) are well designed, calculation methods are required to estimate the extension of a personal energy absorber (PEA) () and the total fall distance (). Thus, the authors conducted 28 tests to validate the accuracy of the energy balance approach for estimating and of VLLSs and propose suitable correction factors to improve the accuracy and safety of the estimated and . For 9 out of 19 tests with a PEA, the difference between the theorical and empirical was 25% or higher, indicating that the energy balance approach is not accurate for estimation of .

Factors influencing unsafe behaviors: A supervised learning approach.

Despite its potential, the use of machine learning in safety studies had been limited. Considering machine learning's advantage in predictive accuracy, this study used a supervised learning approach to evaluate the relative importance of different cognitive factors within the Theory of Reasoned Action (TRA) in influencing safety behavior. Data were collected from 80 workers in a tunnel construction project using a TRA-based questionnaire.

Construction accident narrative classification: An evaluation of text mining techniques.

Learning from past accidents is fundamental to accident prevention. Thus, accident and near miss reporting are encouraged by organizations and regulators. However, for organizations managing large safety databases, the time taken to accurately classify accident and near miss narratives will be very significant.

Knowledge, attitude and practices for design for safety: A study on civil & structural engineers.

Design for safety (DfS) (also known as prevention through design, safe design and Construction (Design and Management)) promotes early consideration of safety and health hazards during the design phase of a construction project. With early intervention, hazards can be more effectively eliminated or controlled leading to safer worksites and construction processes. DfS is practiced in many countries, including Australia, the UK, and Singapore.

A hybrid simulation approach for integrating safety behavior into construction planning: An earthmoving case study.

One of the key challenges in improving construction safety and health is the management of safety behavior. From a system point of view, workers work unsafely due to system level issues such as poor safety culture, excessive production pressure, inadequate allocation of resources and time and lack of training. These systemic issues should be eradicated or minimized during planning.

Modelling and simulation of complex sociotechnical systems: envisioning and analysing work environments.

Unlabelled: Accurate comprehension and analysis of complex sociotechnical systems is a daunting task. Empirically examining, or simply envisioning the structure and behaviour of such systems challenges traditional analytic and experimental approaches as well as our everyday cognitive capabilities. Computer-based models and simulations afford potentially useful means of accomplishing sociotechnical system design and analysis objectives.

Dynamics of safety performance and culture: a group model building approach.

The management of occupational health and safety (OHS) including safety culture interventions is comprised of complex problems that are often hard to scope and define. Due to the dynamic nature and complexity of OHS management, the concept of system dynamics (SD) is used to analyze accident prevention. In this paper, a system dynamics group model building (GMB) approach is used to create a causal loop diagram of the underlying factors influencing the OHS performance of a major drilling and mining contractor in Australia.
