The Health and Safety Risks of Working during Heatwaves on Construction Sites in the Republic of Ireland and the United Kingdom

The construction sector is vulnerable to extreme weather events due to most of the industry's activities being carried out manually by workers outdoors. However, there has been little study of the consequences of heatwaves on construction sites unlike other extreme weather events, such as floods and snowfalls. This research project aims to investigate the health and safety risks associated with heatwaves on construction sites in western Europe, specifically the Republic of Ireland and the United Kingdom. The research applies Failure Mode and Effects Analysis, with the help of five experts in both countries to evaluate these risks based on their likelihood of occurrence, the severity of their impact and their ease of detection. Semi-structured interviews were also carried out with these experts to investigate potential solutions to these risks and barriers to their implementation. The results show there is a lack of knowledge in the area, and an ill-preparedness with regards to employee welfare during hot weather events. There is also a significant lack of governing laws with respect to outdoor working in high temperatures, thus the need for the industry to improve upon health and safety on construction sites during heatwaves. The research explores solutions such as conducting pre-employment health checks and toolbox talks, supplying breathable personal protective equipment, providing suitable rest and welfare facilities, practicing crew rotation and providing mechanical aids where possible. More in-depth interviews with other experts are needed due to the lack of research in the area and its abstract nature.
