Investigation of the causality patterns of non-helmet use behavior of construction workers

摘要

Not wearing a safety helmet can result in serious injuries on construction sites, but the cause of such unsafe behavior is not yet well understood. This paper describes a practical field study to find the factors that influence non-helmet use on construction sites using a real-time tracking system (the Eye on Project or EOP), which is developed by our research team to provide an objective record of helmet use; and which overcomes the deficiencies of traditional recording methods (Le. self-reporting). The application of association rules then combines designated risk factors and finds the causality patterns of non-helmet use. Based on the analyses, this paper develops a method of evaluating workers' risk level involving the intensity of multiple risk factors. (C) 2017 Elsevier B.V. All rights reserved.
