The purpose of this study is to develop a framework for integrating essential safety practices (visualization, job safety analysis and plan–do–check–act) into 5S steps and validate it. First, 18 interviews with a snowball sample of construction workers, safety representatives, supervisors and site and project managers were conducted. A grounded theory method was utilized to code the interview data. The results revealed that the studied construction companies implement a systematic safety-based methodology to minimize construction work injuries. Second, to validate the proposed framework, a pre-test and post-test study was applied. The case and control groups (26 participants) answered a 6S questionnaire before the 6S system and 1 month after implementation. The results revealed that safety climate and productivity significantly increased for the case group but reduced for the control group during time.

本研究的目的是开发一个框架，将基本安全实践（可视化、工作安全分析和计划-执行-检查-行动）整合到 5S 步骤中并对其进行验证。首先，对建筑工人、安全代表、主管以及现场和项目经理的雪球样本进行了 18 次访谈。采用扎根理论方法对访谈数据进行编码。结果表明，所研究的建筑公司实施了一种系统的基于安全的方法，以最大限度地减少建筑工伤。其次，为了验证所提出的框架，应用了前测和后测研究。病例组和对照组（26名参与者）在6S系统实施前和实施后1个月回答了6S问卷。
