Anti-Heat Stress Clothing for Construction Workers in Hot and Humid Weather

Research Abstract

Hong Kong is a typical city, with subtropical climate and high urbanisation.  The nature of atmosphere and urbanised conditions poses irreversible environmental stress on human health.  The construction industry is more susceptible to heat stress because construction work often involves highly demanding physical tasks.  The frequency of verifiable heat-related incidents in the construction industry is higher than many occupational settings.


Current guideline recommends that construction workers should wear thin and light clothes with good permeability when working in hot weather.  However, the guideline lacks precise criteria for designing “appropriate” summer work clothes.  Moreover, inappropriate dress behaviour and insufficient personal protection may pose a high risk of skin cancer because of direct exposure to solar ultraviolet (UV) radiation.


This study adopted a scientific approach to design an anti-heat stress clothing (AHSC) and evaluate its effectiveness.  Findings of laboratory experiment manifested that AHSC was effective in alleviating thermo-physiological and reduction of heat storage by 28.8%.  The well-being of construction workers would be enhanced with AHSC when working in hot weather, and so does productivity.
