The construction industry is one of the most hazardous industries worldwide, and contact with electricity is a major cause of injury and death among construction workers. It is well known that unsafe acts resulting from human error are the primary cause for up to 80% of accidents across various industries, and some studies show that human performance tools may be functional in mitigating these incidents. Accordingly, this paper provides empirical evidence regarding the effectiveness of human performance tools as used to curb the frequency, probability, and severity of accidents. To achieve its objectives, this study first executed an extensive literature review to identify best practices related to human factors in mitigating the risk of electrical incidents. Then, the authors distributed an online questionnaire among various safety managers to determine the effectiveness of each practice in reducing the frequency, probability and severity of these incidents. The results and analysis show which human performance tools are recognized as most effective in helping safety managers mitigate human errors in electrical jobsites. The results of this study and paper will accelerate and transform current injury-prevention practices as well as overcome some of the barriers in the electrical workplace. An easy-to-use and effective set of human performance best practice solutions will be provided based on standards and industry experience.
