Safety and productivity issues are become a vital concern in the construction industry nowadays. Low labor productivity and unsafe working environment have often been claimed to relate each other. Base on that reason, the aim of this study was to identify the most influencing safety practices on construction labor productivity. Questionnaire survey form with the Likert scale questions gave to the respondents to achieve research objectives. Then, the average index method, Kruskal Wallis test, and factor analysis technique were used to analyzed data. The result showed that the using of basic personal protective equipment (PPE) and the existence of safe guard device are the most influencing safety practices on labor productivity. The contractor result is the highest score compare to the client and consultant. This result can be useful to all the stake-holders in construction projects, from the initial to the end of project stages. The most important contribution of this study is the identification of the safety practices factors that give positive influence to the labour productivity. If these factors have been identified, it is easier to prepare the construction process. Construction projects expected to be more productive and also safer.
