Labour Dept Enhances Heat Warning System with Lowered Thresholds
AM730 · 3 SOURCESabout 2 hours ago2 MIN
Summary
The Labour Department will tomorrow enhance the Work Heat Stress Warning System by adding two new conditions that trigger higher-level alerts. The optimization lowers monitoring thresholds when the Observatory issues Extreme Hot Weather tips, and automatically upgrades warnings if temperatures across multiple districts reach 35 degrees or above. The changes respond to public concerns about the system's responsiveness during August's sustained heatwave.
Key Points
- Starting July 28, the system will lower thresholds to trigger higher warnings when the Observatory issues an Extreme Hot Weather Special Tip
- If multiple areas across Hong Kong record 35 degrees or above, the warning level automatically escalates: Yellow becomes Red, Red becomes Black
- Commissioner for Labour Hui Chak-sam states the changes aim to enhance sensitivity to abnormal temperatures and better protect workers
- The department will continue reviewing whether Wet Bulb Globe Temperature data should be incorporated as a system indicator
- Employers who fail to implement appropriate heat prevention measures may face prosecution, with increased enforcement inspections planned
Why It Matters
With Hong Kong experiencing increasingly frequent extreme heat events, the enhanced system provides earlier and more responsive warnings to protect outdoor and indoor workers from heat stress. Employers now face clearer obligations and greater enforcement risk, making compliance with heat prevention measures essential to avoid legal consequences .
