Abstract

Background: This study aimed to provide a comprehensive tool for the economic evaluation of investments in health, safety, and environment (HSE). Methods: This developmental cross-sectional study was conducted on the costs and benefits of HSE investments in a combined cycle power plant in Gilan province, 2021. The components of preventive measure costs (PMCs) and occupational accidents, diseases, and environmental pollution costs (ADPCs) were determined by an expert panel and review of scientific literature. The HSE economic assessment tool (HSE-EAT) was developed in Microsoft Excel software using macro/visual basic coding. The tool was designed to determine the efficient measures using the cost-benefit analysis (CBA) and the combination of control measures with the highest financial benefits using the cost-effectiveness analysis (CEA). Results: The application of the HSE-EAT in a combined cycle power plant showed the highest return on investment (ROI) for installation of drains for ducts of diesel fuel pipes and the lowest ROI value for renovation of emergency eyewash and shower. The ratio of indirect to direct benefits of implementing the preventive measures in the worst-case and best-case scenarios were 3.0 and 1.3, respectively. Conclusion: The HSE-EAT exhibited the advantages of comprehensiveness, flexibility, being user-friendly, and faster and more accurate calculations and could be also used for economic evaluation of health, safety and environmental initiatives in other industries and organizations.

开发用于联合循环发电厂健康、安全和环境倡议经济评估的软件工具
背景:本研究旨在为健康、安全和环境(HSE)投资的经济评估提供一个全面的工具。方法:对2021年吉兰省一家联合循环电厂的HSE投资成本和收益进行了发展横断面研究。预防措施成本(PMCs)和职业事故、疾病和环境污染成本(ADPCs)的组成部分由一个专家小组和科学文献的审查确定。HSE经济评价工具(HSE- eat)在Microsoft Excel软件中使用宏/visual basic编码开发。该工具旨在使用成本效益分析(CBA)确定有效措施,并使用成本效益分析(CEA)结合具有最高经济效益的控制措施。结果:在某联合循环电厂中应用HSE-EAT的投资回报率最高的是柴油管道排水管的安装,投资回报率最低的是应急洗眼器和淋浴器的改造。在最坏情况和最佳情况下,实施预防措施的间接效益与直接效益之比分别为3.0和1.3。结论:HSE-EAT具有全面、灵活、操作方便、计算速度快、准确等优点,可用于其他行业和组织的健康、安全和环境经济评价。
