Evaluation of Factors Affecting the Safety of Construction Workers
Unskilled construction workers in Iran have unique characteristics that differentiate them from the skilled workforce, both as a result of their different backgrounds and cultures and as a consequence of their lack of knowledge about national practices and the Iranian constitution as well as legislation. These features cause unskilled construction workers to form a particular attitude towards work that is reflected in their risk of work-related accidents, which tends to be higher than that average of accidents among other Iranian workers. The purpose of this study was to introduce strategies for accident prevention in construction sites and prioritize them according to factors leading to accident, which were drawn from survey data analysis regarding the type and extent of dangers to which skilled and unskilled workers in Iran are exposed at construction sites. First, 12 factors leading to accident and 11 strategies for accident prevention were identified based on results of statistical analysis of questionnaires administered to 59 skilled and unskilled workers working at construction sites in the Tabriz. The strategies for accident prevention were then prioritized according to their relative importance as determined through the analytic hierarchy process and through a second survey administered to 96 project managers and executive engineers who had experience in managing workers at construction sites all over the country.
