Analysis of Construction Workers’ Health and Safety in Cold Weather Conditions

Abstract

Extreme cold weather conditions affect construction workers’ health and safety performance. Hence, the goal of this article is to identify and analyze these challenges so that effective measures can be developed and implemented to mitigate or eliminate them. To this end, a questionnaire was created and circulated through the online platform QuestionPro. The Kruskal–Walli’s test was used to examine the physical and mental health issues identified by the 111 responders, and quantitative analysis was performed by using physiological indicators such as heart rate and personal indicators, including degree of comfort and acclimation. The results showed that physical obstacles such as hypothermia and respiratory issues were perceived differently based on heart rate and garment comfort; and mental issues, such as poor concentration and frequent mood swings, varied with the workers’ heart rate and level of acclimatization. Some of the strategies developed for protecting the workers are ensuring that they wear sufficient layers of clothing and heated gloves and have access to technologies such as infrared heaters. Existing practices and legislation that control construction “workers” safety in extreme cold weather conditions are also addressed. The findings of this article will help construction industry professionals effectively manage projects while ensuring their workers’ safety in harsh cold weather conditions.
