Globally, falls from height (FFH) are a substantial public health jeopardy and are among the important leading causes of serious and fatal injuries for construction workers. A comprehensive understanding of the causal factors in FFH incidents is urgently required; however, the literature appears to lack a scientific review of FFH. In this study, 297 articles that contribute to the topic of fall incidents were reviewed. Seventy-five (75) articles met the criteria for relevance and were aggregated in a database to support a critical review. A synthesis of macro-variables approach was adopted rather than a structured meta-analysis. Such a method of analysis provides the flexibility to combine previous studies' findings. The most common factors associated with FFH are risky activities, individual characteristics, site conditions, organizational characteristics, agents (scaffolds/ladders) and weather conditions. The outcomes contributed to identifying the most significant research area for safety enhancement by improving engineering facilities, behaviour investigations and FFH prevention methods.

This paper focuses on construction workers’ unsafe behaviors and develops a cognitive model of construction workers’ unsafe behaviors (CM-CWUB). In the construction industry, many accident investigations reveal that workers’ unsafe behaviors are the most frequent and direct causes of on-site accidents, and thus need to be addressed urgently. Based on cognitive and social psychology theories and existing accident causation models, this paper develops a CM-CWUB by adopting a five-stage form, specifically representing the construction workers’ cognitive processes when confronted with potential hazards on construction sites. Using a cognitive perspective can reveal the mechanism of human error and thus can elucidate how unsafe behaviors are produced. The five stages include obtaining information, understanding information, perceiving responses, selecting response, and taking action, with obtaining information and selecting response as the two key stages. Obtaining information elaborates construction w...

Safety climate can benefit contractors, specialty contractors, and owners of industries by providing them with the knowledge of attitudes and perceptions that can help to consistently achieve better safety performance. The objective of this research was to determine safety climate that would enhance safety culture and positively impact perceived safety performance on construction projects. A safety climate questionnaire survey was conducted on the construction sites of a leading construction company and its subcontractors in Hong Kong. Approximately, 1,500 hard copy questionnaires were distributed and the response rate was excellent, resulting in 1,120 valid questionnaires being collected from 22 construction projects. By means of factor analysis, two underlying safety climate factors were extracted, accounting for 43.9% of the total variance. Multiple regression analysis confirmed that these climate factors, “management commitment and employee involvement” and “inappropriate safety procedure and work pra...

The concept of safety culture is relatively new in the construction industry; however, it is gaining popularity due to its ability to embrace all perceptional, psychological, behavioral, and managerial factors. To address the lack of a verifiable process to analyze construction safety culture, this technical note presents a robust conceptual model that has its roots firmly entrenched in pertinent academic and applied literature. It provides a critical review of the term “safety culture”; along with distinct yet related concepts (i.e., safety climate, behavior-based safety, and safety system). It also compares the proposed model with available safety culture models in order to demonstrate its applicability in construction site environments.

Safety issues have gained vital importance throughout the construction industry. Many construction companies around the world are implementing safety, health, and environmental management systems to reduce injuries, eliminate illness, and to provide a safe work environment in their construction sites. This paper describes an exploratory study of site safety management in construction sites’ environments. It explains a successful, modern safety, health and environmental management system for a leading construction company based in Hong Kong. A typical site-specific safety plan was utilized to provide safety guidance throughout the construction project. A safety management survey was conducted to determine the status of safety in the construction sites. All employees of the company and its subcontractors participated in the survey from 20 construction projects. In total, 1,022 valid records were obtained from the construction sites. The analysis provided useful information on eight aspects of construction s...

Chinese scaffolders not using safety harnesses is commonplace, despite scaffolders being constantly exposed to fall hazards on construction sites and the use of safety harnesses being required by law. The causes of Chinese scaffolders not using safety harnesses are explored through theoretical analyses and empirical tests. In theoretical analyses, based on Surry’s model, the major cause of scaffolders not using safety harnesses was identified as their personal decisions not to do so. The theory of planned behaviour (TPB) was used to analyse why scaffolders decided not to use safety harnesses. In empirical tests, scaffolders on seven sites completed questionnaires developed based on TPB, and nine safety officers participated in a focus group meeting to collect their views on scaffolders’ use of safety harnesses. In addition, two scaffolders, one gangmaster, one safety officer, and one foreman were interviewed to verify the results of the questionnaire survey. Empirical tests results show that the inconvenience and discomfort of using safety harnesses, underestimating the risk of not using safety harnesses, negative pressures from gangmasters, foremen, and safety officers, and lack of safety lines are causes of scaffolders deciding not to use safety harnesses. Measures enhancing the use of safety harnesses are proposed based on the results of empirical tests.
