Predicting safety culture: the roles of employer, operations manager and safety professional

Introduction: This study explores predictive factors in safety culture. Method: In 2008, a sample 939 employees was drawn from 22 departments of a telecoms firm in five regions in central Taiwan. The sample completed a questionnaire containing four scales: the employer safety leadership scale, the operations manager safety leadership scale, the safety professional safety leadership scale, and the safety culture scale. The sample was then randomly split into two subsamples. One subsample was used for measures development, one for the empirical study. Results: A stepwise regression analysis found four factors with a significant impact on safety culture (R² = 0.337): safety informing by operations managers; safety caring by employers; and safety coordination and safety regulation by safety professionals. Safety informing by operations managers (ß = 0.213) was by far the most significant predictive factor. Impact on industry: The findings of this study provide a framework for promoting a positive safety culture at the group level.     

Safety leadership and safety performance in petrochemical industries: The mediating role of safety climate

This study examines the relationship among three latent variables: safety leadership, safety climate, and safety performance. Employees from 23 plants in seven departments of a petrochemical company in central Taiwan completed a questionnaire survey. From this, a sample of 521 responses was randomly selected. Structural equation modeling (SEM) analysis using the AMOS 5.0 was employed to test the hypothesized model relating the above-mentioned variables. The results indicate that the model was supported, and that safety climate mediated the relationship between safety leadership and performance. Practical implications of these results for process safety management in the petrochemical industries are discussed.     

The predictive validity of safety climate

PROBLEM: Safety professionals have increasingly turned their attention to social science for insight into the causation of industrial accidents. One social construct, safety climate, has been examined by several researchers [Cooper, M. D., & Phillips, R. A. (2004). Exploratory analysis of the safety climate and safety behavior relationship. Journal of Safety Research, 35(5), 497-512; Gillen, M., Baltz, D., Gassel, M., Kirsch, L., & Vacarro, D. (2002). Perceived safety climate, job Demands, and coworker support among union and nonunion injured construction workers. Journal of Safety Research, 33(1), 33-51; Neal, A., & Griffin, M. A. (2002). Safety climate and safety behaviour. Australian Journal of Management, 27, 66-76; Zohar, D. (2000). A group-level model of safety climate: Testing the effect of group climate on microaccidents in manufacturing jobs. Journal of Applied Psychology, 85(4), 587-596; Zohar, D., & Luria, G. (2005). A multilevel model of safety climate: Cross-level relationships between organization and group-level climates. Journal of Applied Psychology, 90(4), 616-628] who have documented its importance as a factor explaining the variation of safety-related outcomes (e.g., behavior, accidents). Researchers have developed instruments for measuring safety climate and have established some degree of psychometric reliability and validity. The problem, however, is that predictive validity has not been firmly established, which reduces the credibility of safety climate as a meaningful social construct. The research described in this article addresses this problem and provides additional support for safety climate as a viable construct and as a predictive indicator of safety-related outcomes. METHODS: This study used 292 employees at three locations of a heavy manufacturing organization to complete the 16 item Zohar Safety Climate Questionnaire (ZSCQ) [Zohar, D., & Luria, G. (2005). A multilevel model of safety climate: Cross-level relationships between organization and group-level climates. Journal of Applied Psychology, 90(4), 616-628]. In addition, safety behavior and accident experience data were collected for 5 months following the survey and were statistically analyzed (structural equation modeling, confirmatory factor analysis, exploratory factor analysis, etc.) to identify correlations, associations, internal consistency, and factorial structures. RESULTS: Results revealed that the ZSCQ: (a) was psychometrically reliable and valid, (b) served as an effective predictor of safety-related outcomes (behavior and accident experience), and (c) could be trimmed to an 11 item survey with little loss of explanatory power. IMPACT ON INDUSTRY: Practitioners and researchers can use the ZSCQ with reasonable certainty of the questionnaire's reliability and validity. This provides a solid foundation for the development of meaningful organizational interventions and/or continued research into social factors affecting industrial accident experience.     

The influence of supervisor leadership practices and perceived group safety climate on employee safety performance

The current study investigates the influence of the leadership practices of first-line supervisors on the safety compliance and safety participation of the employees who work for them. Contingent reward and transformational leadership are examined under conditions of positive and non-positive group safety climate in both the manufacturing and constructions sectors. Using moderated regression models (Aguinis, 2004) results indicate that greater levels of transformational and contingent reward leadership are both associated with greater levels of safety compliance and safety participation behavior, however group safety climate moderates the leadership-safety compliance relationships. Under positive group safety climate conditions employee safety compliance behavior improves as supervisor’s leadership practices increase; under non-positive group safety compliance conditions there is no improvement in safety compliance with improvements in supervisor’s leadership practices. The results provide further support to the growing literature on the value of strong group safety climates for improving safety compliance behavior, as well as the value in improving the leadership practices of first-line supervisors.

The nature of safety culture: a review of theory and research

This paper reviews the literature on safety culture and safety climate. The main emphasis is on applied research customary in the social psychological or organisational psychological traditions. Although safety culture and climate are generally acknowledged to be important concepts, not much consensus has been reached on the cause, the content and the consequences of safety culture and climate in the past 20 years. Moreover, there is an overall lack of models specifying either the relationship of both concepts with safety and risk management or with safety performance. In this paper, safety culture and climate will be differentiated according to a general framework based on work by Schein (1992 Schein) on organisational culture. This framework distinguishes three levels at which organisational culture can be studied — basis assumptions, espoused values and artefacts. At the level of espoused values we find attitudes, which are equated with safety climate. The basic assumptions, however, form the core of the culture. It is argued that these basic assumptions do not have to be specifically about safety, although it is considered a good sign if they are. It is concluded that safety climate might be considered an alternative safety performance indicator and that research should focus on its scientific validity. More important, however, is the assessment of an organisation's basic assumptions, since these are assumed to be explanatory to its attitudes.
