Abstract
Wastewater treatment plants (WWTPs) are an indispensable part of the infrastructure of modern cities. However, because of the existence of many confined working spaces in them, they also pose significant risks of occupational hazards for workers. Therefore, this study was conducted on WWTP workers in Kaohsiung, Taiwan to explore the connections among the perceived control, safety attitude, and safety performance of WWTP workers. In total, 123 valid questionnaires were returned for descriptive statistical analysis, variance analysis, correlation analysis, and hierarchical regression analysis. According to the analysis results, the WWTP workers in this study indicated a mid to high level of perceived control, and they generally believed they were also responsible for industrial safety management. The variance analysis results showed that workers of a different gender, age, service unit, and seniority had significantly different safety attitudes. The hierarchical regression analysis results indicated that the perceived control of the WWTP workers had a significant influence on their safety performance through their safety attitude, which served as a mediator between perceived control and safety performance. It is hoped that these findings can provide references for WWTP managers and workers in their daily communication, operation, and safety management system introduction to ensure better safety.

As found in the study by Kuo et al [51], perceived control is a significant predictor of safety behavior climate and occupational accidents through safety culture; the safety attitude as a sub-dimension of safety culture was selected in this study to test the influence of safety attitude of WWTP workers as a mediator
Summary
Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. Wastewater treatment, a fundamental part of national infrastructure, is considered one of the major indicators of urban modernization. Yearbook published by the Institute for Management Development (IMD) in Lausanne, Switzerland, the percentage of the population served by wastewater treatment plants (WWTPs) is listed as an indicator in the “Health and Environment” dimension for the life quality ranking. Better wastewater treatment can help to improve a country’s image and competitiveness and the quality of its environment by collecting, treating, and releasing wastewater into the environment when the wastewater meets the environmental standards
