  "account": "The Labour Department of Hong Kong has announced a refined heat stress at work warning system that will be more sensitive to extreme hot weather. Two new conditions have been added to the system starting from Friday, increasing its sensitivity in triggering a warning, which could result in more red and black heat stress at work warnings in the future. The amber warning will be issued immediately upon an extreme heat alert from the Observatory, while the threshold for raising the warning level will be lowered to allow for earlier activation. If temperatures reach 35 degrees Celsius or above at 40 percent of the weather forecaster's 39 monitoring stations, the warning will automatically be elevated by one level. Deputy Commissioner (Occupational Safety and Health) Ivanhoe Chang explained the changes were necessary after recording record-high temperatures earlier in the month. He stated that Hong Kong will face more days with higher warning levels under the enhanced system. Chang anticipates up to four to seven red warnings and one to two black warnings if future weather conditions follow the trend of the past three years. The system will still rely on the Hong Kong Heat Index, which considers temperature, humidity, wind speed, and solar radiation, as it better reflects Hong Kong's subtropical conditions given its relatively humid summer. However, the department is open to other evaluation tools and will continue monitoring the refined system to determine if additional adjustments are required.",
