Hong Kong's labour chief, Sam Hui Chark-shum, has said that the city is open to classifying heatstroke as an occupational disease. This comes after a review of Hong Kong's revamped heat warning system, which showed it would have issued stronger alerts on two extremely hot days in August: August 8 and August 9. On August 9, the temperature reached 36.9 degrees Celsius (98.4 Fahrenheit), breaking records since 1884. The revised system would have triggered a red alert on August 9 and even a black warning on August 8, indicating more severe heat stress conditions. The current heat stress warning system has three levels: amber, red, and black, advising employers to take measures such as rest arrangements for outdoor workers. This review is significant because it highlights the potential consequences of heat-related illnesses in the workplace and suggests that stronger warnings may have been warranted during those hot days.
