Thermal Environments in the Construction Industry: A Critical Review of Heat Stress Assessment and Control Strategies
2019
In the light of climate change predictions, the increasing number of hot days will cause a significant impact on public health, mortality rates, energy demand and economy of Australia. Heat is also an occupation hazard, which is a growing concern in many industries. Heat stress hazards can be categorized as clinical, human performance diminishing and accident causing. The risk can be exaggerated in certain industries, including the construction industry, due to specific environmental conditions, work characteristics and occupational settings. This chapter discusses the main problems and risks associated with heat stress, with a particular emphasis on the construction industry. Various heat stress indices and advances in the assessment of heat stress in recent years are discussed. Finally, this chapter discusses the strategies and controls that can be implemented to mitigate the impact of heat stress in the construction industry. Various acclimatization protocols, hydration, self-pacing and exposure time limits or temperature risk control regimes are discussed by analysing standards, guidelines and policies and practices. This chapter contributes to resolving a timely and strategic occupational hazard through a holistic view of the thermal environment in construction industry settings.
