Sweat-soaked laborers and tenants residing in subdivided flats in Hong Kong endure the severe summer heat unabated.
In the sweltering summer months of Hong Kong, the city has been breaking temperature records, with 2024 marking the warmest April and the first half-year on record[10]. This escalating heat has a significant impact on vulnerable populations, particularly outdoor workers and elderly residents living in cramped subdivided flats.
To combat the rising temperatures and prevent heat-related illnesses, several strategies are being implemented and advocated to ensure the safety of Hong Kong's residents.
## Early Warning Systems and Information
Staying informed about the weather is crucial during heatwaves. Services like the Hong Kong Observatory provide heat stress warnings and alerts, helping residents prepare for extreme heat[1][3]. The Senior Citizen Home Safety Association also offers "Weather Information for Senior Citizens," ensuring timely updates for the elderly[3].
## Cooling Measures
Cooling centers have been established as a relief for those experiencing extreme heat. Homeowners and businesses are encouraged to use air conditioning and cooling systems to keep indoor spaces comfortable[2].
## Workplace Adjustments
Employers play a significant role in protecting their workers during heatwaves. Under the government's Heat Stress at Work Warning system, employers are advised to adjust work schedules or suspend work under red or black alerts and provide more rest time for outdoor workers[1].
## Community Engagement and Education
Raising community awareness about heatwave risks is essential, particularly for vulnerable populations such as seniors[3]. Education on how to recognize and respond to heat-related illnesses is also crucial[2].
## Urban Planning Initiatives
Incorporating heatwave risk assessments into urban planning can help mitigate the urban heat island effect. Green corridors and reflective cool roofs and pavements are being proposed to reduce temperatures in public spaces[2].
## Safety Tips for Individuals
- Stay Hydrated: Drink plenty of water throughout the day. - Avoid Peak Sun Hours: Limit outdoor activities during the hottest part of the day. - Dress Appropriately: Wear light, loose clothing that allows for good airflow. - Monitor Health: Be aware of signs of heat illness, such as dizziness, nausea, and headaches[1][3].
These strategies aim to mitigate the adverse effects of extreme heat on both individual safety and community health in Hong Kong. Ling Chan, a street cleaner in her 70s, suffered from heatstroke last year during Hong Kong's hottest summer on record. Under a red or black alert, bar benders and porters are advised to stop work completely, while other outdoor workers should be granted more rest time.
The Community Climate Resilience Concern Group is working to create accessible cooling spaces throughout Hong Kong, while SoCO urges the government to establish a permanent scheme of subsidies for energy bills in the long term. The group also calls on policymakers to design public spaces that better account for the unequal impact of climate change.
As Hong Kong continues to face increasing temperatures, it is crucial that these strategies are implemented and supported to ensure the safety and well-being of all its residents.
