Public debate over Hong Kong’s recent heatwave has rightly focused on protecting frontline workers. However, one group remains largely absent from the discussion: site managers and project supervisors who carry responsibility for worker safety, project delivery and contractual compliance. Increasingly, they are being asked to balance those obligations without a clear framework.
Recent criticism of Hong Kong’s Heat Stress at Work Warning system has focused on whether the Hong Kong Heat Index adequately reflects conditions faced by outdoor workers exposed to direct sunlight. Three former directors of the Hong Kong Observatory have argued that the internationally recognised Wet Bulb Globe Temperature (WBGT) might be more suitable for assessing heat risks at open-air worksites.

Regardless of which methodology ultimately prevails, the debate has exposed a gap between contractual requirements and operational reality. What should site managers do when local conditions appear unsafe but the official warning framework does not respond accordingly?

The latest generation of construction contracts increasingly recognises extreme heat as a potential ground for extension of time claims. However, such relief is linked to the Labour Department’s Heat Stress at Work Warning system.

That helps explain why the heat on August 9 raised concern. Despite temperatures reaching 39.8 degrees Celsius (103.6 Fahrenheit) in Sheung Shui, the Heat Stress at Work Warning remained at amber, the lowest level. Site managers who believed stronger precautions were warranted could have found themselves without the higher-level official trigger on which contractual protections depend.

The core issue the Labour Department needs to address is what happens when a site manager believes conditions on the ground warrant stronger precautions, but the official trigger on which contractual protections depend is absent.
