Transcript
17 Ms Lee Hui Ying asked the Minister for Sustainability and the Environment given the projection that 2026 may be among the hottest years on record (a) whether an update can be provided on the effectiveness of the Heat Stress Advisory since its launch; (b) whether there are plans to review its accuracy, localisation and accessibility amid rising heat stress days; and (c) what is its success in integrating into workplace, school and public health protocols.
Ms Grace Fu Hai Yien: The Heat Stress Advisory was launched in July 2023 to provide simple tips for the public to plan their prolonged outdoor activities based on prevailing heat stress levels. Heat stress information is available on the myENV application. We have observed higher engagements with the application's heat stress feature during the hot season from March to May each year when heat stress risks are elevated.
The Meteorological Service Singapore has expanded its network of Wet-Bulb Globe Temperature sensors from nine in 2023 to 27 today and will install more sensors islandwide to give the public more location-specific heat stress information through the myENV application. Additionally, we will explore enhancements to improve the myENV application's usability and accessibility.
Agencies have also adapted the Heat Stress Advisory for sector-specific needs. This includes the Ministry of Manpower's heat stress framework for outdoor work, the Ministry of Education's guidelines for schools to ensure the safety and well-being of students amid the hot weather, and the Ministry of Health's heatwave response framework for healthcare institutions and eldercare facilities to better manage heat stress risks for both staff and patients.
