Abstract
Introduction: Positive safety attitude of employees is directly associated with workplace safety, and it can decrease occupational accidents through increasing the number of safety acts. Assessment of employees’ safety attitude in workplaces can be more helpful to identify underlying causes of unsafe acts. The main aim of this study was to assess safety attitude and its’ relationship with different personal and occupational variables in a number of manufacturing companies, located in Urmia City, Iran.
Material and Method: In this study, the safety attitude of 194 employees was measured in 9 manufacturing companies using a questionnaire with acceptable validity and reliability. The questionnaire consisted of two parts: participants’ personal and job related information, as well as 46 safety attitude related questions. The questions of safety attitude was measured using a five-point Likert scale in form of ten main aspects.
Result: The results indicated that majority of participants (78.9 %) had a moderate safety attitude level and the mean (±SD) score of total safety attitude was 3.19 (±0.25). “Commitment to safety and participation in safety activities” and “safety talk and risk information communication” obtained the highest and lowest scores of safety attitude factors, with mean (SD) of 3.97(±0.52) and 2.53(±0.58), respectively. In addition, the participants from private companies showed a better safety attitude than those of governmental companies (P-value<0.05). Managers and workers, who had previously received safety training, reported a different attitude toward various factors of safety attitude, in comparison with untrained groups.
Conclusion: Since the majority of participants had a moderate safety attitude, this research suggests the study companies to attempt in order to increase the quantity and quality of safety training courses, as well as safety communication of managers and supervisors with workers for improving their attitude toward safety and subsequently decreasing occupational accidents.

Abstract
Introduction: Complex sociotechnical systems, such as automotive industry, require a proper macro-ergonomic approach to design and implement the work system at micro-ergonomic level. The purpose of this study was to develop and validate effective macroeconomic factors to improve productivity, health and safety of employees in the automotive industry based on Holden & Karsh model.
Material and Methods: At the first step, relevant documents were reviewed, and then experts were interviewed to identify macro-ergonomic factors. The identified factors were categorized into four groups based on Holden & Karsh’s model. In the follow-up phase of the study, then, the content validity of the factors was calculated using Delphi technique in the form of an expert panel. Finally, validity acceptance was assessed using mean content validity index, and agreement between experts was evaluated using modified kappa coefficient
Results: 28 main factors were identified and categorized into four subgroups, including personnel, unit /department, organization and environment factors. 19 main factors were selected as the effective macro-ergonomic factors to improve employee’s productivity, health, and safety. The content validity index and the modified kappa coefficient were calculated as 0.901 and 0.90, respectively.
Conclusion: Macro-ergonomic factors identified in this study can be considered to improve employee’s productivity, health, and safety in the automotive industry. These factors can be used as specific context-based criteria for an ergonomic evaluation in the automotive industry, or even be generalized to other industries, organizations and companies.
