Hong Kong’s Labour Department has revised its heat stress warning system in response to public outcry over a lack of alerts during recent record temperatures. The updated Heat Stress at Work Warning (HSWW) system will incorporate two new trigger conditions, effective Friday, aiming to provide earlier warnings to employers. Despite the changes, the system remains non-binding, meaning companies are not legally obligated to implement preventative measures. Critics had argued the original thresholds were too high, failing to reflect the real risks faced by outdoor workers. The department stated the adjustments were made to better protect employees from heat-related illnesses. However, concerns persist about the lack of enforcement mechanisms within the HSWW system, leaving worker safety reliant on employer discretion.
