Hong Kong Heat Wave Sparks Debate
As temperatures soar to a record 36.9 degrees Celsius, the city's heat-stress warning system for outdoor workers is under scrutiny, while India urges recognition of heat stress as an occupational hazard

Hong Kong's heat-stress warning system for outdoor workers is under debate due to the prolonged hot weather. The maximum temperature recorded at the Hong Kong Observatory reached 33 degrees Celsius or above for nine consecutive days in August, marking the longest streak of very hot days for the month.
The Labour Department's heat stress warning signals are intended to alert outdoor manual workers and those indoors with limited ventilation to risks. However, the effectiveness of these signals has been questioned, particularly by outdoor workers who are most affected by the heat.
On Sunday, the Observatory recorded a maximum temperature of 36.9 degrees at its headquarters in Tsim Sha Tsui, the highest since records began in 1884. This extreme heat has prompted concerns about the well-being of outdoor workers, including construction workers and street cleaners.
In India, workers and civil society groups are urging the Labour Ministry to recognize heat stress as an occupational hazard. They argue that binding protections and income safeguards are vital as extreme heat threatens health and livelihoods. India is estimated to have more than 380 million workers exposed to hazardous occupational heat levels every year.
## Why it matters Globally, heat stress is projected to cause productivity losses equivalent to around 80 million full-time jobs annually by 2030. India may account for around 34 million of the projected global productivity losses due to heat stress by 2030. Agriculture, construction, and other climate-sensitive sectors are particularly vulnerable to heat stress. The recognition of heat stress as an occupational hazard could lead to better protections and safeguards for workers in these sectors.
The debate over heat-stress warning systems and occupational hazards highlights the need for governments and employers to take action to protect workers from the effects of extreme heat. As the world grapples with the challenges of climate change, it is essential to prioritize the health and well-being of workers who are most vulnerable to heat stress.
