Safety cognitive ability is a key factor influencing unsafe behavior. However, the existing achievements have not yet involved the division of the hierarchical relationship of factors influencing safety cognition and lack a quantitative evaluation system of safety cognitive ability. The purpose of this paper is to find out the deficiencies in the safety cognition of workers in high-risk construction positions and to provide practical suggestions for improving their safety cognitive ability and reducing unsafe behavior.

Based on the iceberg model, the factors influencing the safety cognitive ability of workers in high-risk construction positions and their hierarchical relationship were determined, and an evaluation index system consisting of four primary indicators and 20 secondary indicators was constructed. The game theory algorithm was used to optimize the subjective and objective weights of the indicators calculated by the sequential analysis method (G1) and the entropy weighting method (EWM) to obtain the optimal combination weight value. The Matlab software was used for cloud mapping and similarity calculation to determine the safety cognitive ability level of the object to be evaluated.

The research results indicate that the comprehensive level of safety cognitive ability of scaffolders in this construction project is at “Level III”, the fundamental factors and compliance factors are at “Level IV”, the auxiliary factors and driving factors are at “Level III”. This conclusion aligns with the situation learned from the previous field investigation, which validates the feasibility and scientificity of the proposed evaluation method.

Considering that the safety cognitive ability of construction workers is constantly changing, this study has not yet delved into the specific impacts of various influencing factors on the level of safety cognitive ability. Future research can utilize simulation software, such as MATLAB and Vensim, to construct dynamic simulation models that accurately simulate the changing rules of construction workers’ safety cognitive ability under the influence of different factors.

This research broadens the application scope of the iceberg model, enriches the analysis model of the factors influencing the safety cognitive ability of workers in high-risk construction positions and provides a novel perspective for similar research. The safety cognitive ability evaluation method proposed in this paper can not only accurately evaluate the safety cognitive ability level of workers in high-risk positions such as scaffolders but also provide practical suggestions for improving the safety cognitive ability of workers, which is of great significance to improve the safety management level and reduce unsafe behavior in the construction field.

This research fills the research gap of workers in high-risk construction positions and the quantification of safety cognitive ability. The iceberg model is used to realize the hierarchical division of the factors influencing safety cognitive ability. Additionally, an evaluation method for the safety cognitive ability of workers in high-risk construction positions based on the game theory combination weighting method and cloud model is proposed, which realizes the quantitative evaluation of safety cognitive ability.

While research on workplace safety spans across disciplines in medicine, public health, engineering, psychology, and business, research to date has not adopted a multilevel theoretical perspective that integrates theoretical issues and findings from various disciplines. In this chapter, we integrate research on workplace safety from a variety of disciplines and fields to develop a multilevel model of the processes that affect individual safety performance and safety and health outcomes. In doing so, we focus on cross-level linkages among national, organizational, and individual-level variables in relation to the exhibition of safe work behavior and occurrence of individual-level accidents, injuries, illnesses, and diseases. Our modeling of workplace safety is intended to fill a theoretical gap in our understanding of how the multitude of individual differences and situational factors interrelate across time to influence individual level safety behaviors and the consequences of these actions, and to encourage research to expand the limits of our knowledge.

Attentional bias toward safety (ABS) is a positive safety cognitive ability that could encourage individuals to engage in proactive safety behaviors; however, there is a lack of systematic sorting out of the driving mechanism of ABS. This study aims to identify the influencing factors and underlying mechanisms of ABS among construction workers (CWs) in China, thereby enhancing the practice of construction safety management.

An exploratory study using the open-ended approach of grounded theory was conducted, including 25-depth interviews with CWs. Based on the interviews’ records, a scale for measuring CWs’ ABS was developed and an empirical study on 554 workers was performed. The ABS scale was validated in conjunction with an ABS modification training experiment published by the authors’ team, and the theoretical model of the driving mechanism of CWs’ ABS was obtained.

The results showed that the six driving factors of construction workers’ ABS include organizational factors, risk perception, safety awareness, safety investment, job stress and workers’ educational level. This paper also identified the critical approach to improving workers’ ABS as an effective intervention on risk perception. In addition, the ABS scale was found to be effective in measuring the ABS level.

This paper is of importance in reducing the unsafe behaviors of construction workers and preventing and promoting the sustainable development of construction enterprises.

Workplace safety has been a persistent issue for safety-critical organizations. Based on self-verification theory, this study investigates how authentic leadership affects safety behaviors in a collectivistic context.

This research collected 259 matching questionnaires for high-speed railway (HSR) drivers and their supervisors in China. Specifically, HSR drivers were invited to fill in their general perceived authentic leadership, person-organization fit and collectivistic orientation. In addition, their direct supervisors were invited to assess their safety behaviors.

Authentic leadership exhibits a significant positive impact on safety compliance and safety participation, implying that authentic leadership positively impacts safety behavior. The person-organization fit partially mediated the relationship between authentic leadership and safety behavior (safety compliance and participation). Furthermore, collectivistic orientation moderates the relationship between authentic leadership and person-organization fit.

The findings of this study provide important insights into authentic leadership and person-organization fit for developing effective strategies to improve workplace safety.

Unsafe behavior is a major cause of safety accidents, while in most management measures for unsafe behavior, the construction workers are generally managed as a whole. Therefore, this study aims to propose group management of construction workers' unsafe behavior considering individual characteristics.

A cognitive process model with ten cognitive factors was constructed based on cognitive safety theory. The questionnaire was developed and validated based on the cognitive model, and the results showed that the questionnaire had good reliability and validity, and the cognitive model fitted well. Latent class analysis was used to classify the unsafe behaviors of construction workers.

Four categories of cognitive excellent type, cognitive failure type, no fear type and knowingly offending type were obtained. Workers of cognitive excellent type have good cognitive ability and a small tendency for unsafe behaviors. Workers of cognitive failure type have poor cognitive ability and the potential for cognitive failure in all four cognitive links. Workers of no fear type have weak cognitive ability, and cognitive failure may occur in discovering information and choosing coping links. Workers of knowingly offending type have certain cognitive abilities, but cognitive failure may occur in choosing coping link.

This study formulates targeted management measures according to the potential characteristics of these four types and provides scientific theoretical support for the personalized management of unsafe behavior.

The purpose of this paper is to investigate the understanding of industrial safety signs and messages by registered and non‐registered safety officers in Hong Kong with ten different user factors, and examine the relationship between cognitive sign features and sign comprehensibility.

The research methodology includes the survey development and appropriate statistical analyses. In total, 92 Hong Kong Chinese participated voluntarily in the study. A questionnaire survey was used to collect information about demographics, personal experience on safety and health issues, experience of reviewing safety sign information, comprehension scores, and the ratings of sign features for 30 industrial safety signs used in Hong Kong. The effect of ten user factors on sign understanding for the design of highly usable safety signs was examined.

Of the ten factors tested, only the factor of possession of registered safety officer (RSO) status was a significant predictor of comprehension performance. As expected, comprehension scores varied with the cognitive sign features of familiarity, concreteness, simplicity, and meaningfulness.

The currently used industrial safety signs should be redesigned as soon as possible, with careful consideration of cognitive sign features. To make the results more generally applicable, further research is needed to collect more data, particularly from females.

This research suggests that an effective education program for promoting the intended messages of industrial safety signs in various industries and work environments should be conducted as soon as possible. Safety officers, especially those who work in the construction industry need to play a more prominent role in ensuring workplace safety, and in transferring safety knowledge to the workers.

There is a need to enhance RSOs' risk perception and to increase awareness of the importance of safety signs through training programs, so as to improve workplace safety and organizational safety culture. The redesigned safety signs need to be launched with a public education program.

The paper's findings emphasize the need to create awareness of the importance of industrial safety and promote understanding of safety sign meanings amongst people in their work environments. Useful information for the design and use of safety signs was generated.
