Impact of Construction Workers' Physical Health and Respiratory Issues in Hot Weather: A Pilot Study

Construction sector encounters highest workplace accidents. The hazardous nature of construction worksites cannot be eliminated, but efforts can be taken to reduce the workplace accidents through improved safety practices. Ignoring the unsafe behavior and practices in workplace leads to increase in workplace injuries and mortalities. Outdoor occupation has experienced increased mortality rates due to compromised attention on workers' health and safety practices. Incidence of mortalities due to respiratory issues have been on the rise during hot weather conditions. Performing in hot temperatures can further trigger various other health ailments such as heat cramps, heat exhaustion, heat edema, and mental health issues. The aim of this study is to identify the effects of hot weather on construction workers' health and to develop a predictive model on workers' respiratory issues based on various demographic factors. To achieve this, a questionnaire survey was developed and distributed to workers in construction industry. The results of the survey revealed that the effects of temperature on workers' health is not uniform and varies based on attributes such as gender and type of construction sector. The outcomes of this study will help project managers and safety professionals to develop preventive measures for workers performing in extreme temperatures.
