MOM Enhances Heat Stress Protection for Workers Amid Rising Heat Risks

1            As part of the Whole-of-Government efforts to strengthen Singapore’s resilience to a warming climate, the Ministry of Manpower (MOM) has enhanced the Heat Stress Management Framework to better protect outdoor workers from heat-related risks.  Employers will have three months to put the necessary measures in place before the enhanced measures take effect on 1 December 2026.

2            The enhancements elevate four existing recommended practices to mandatory requirements. These four measures were previously recommended under the Heat Stress Framework for Outdoor Work and have been widely adopted by employers. MOM is now making them mandatory to ensure consistent implementation across the industry. Employers will be required to:

• establish heat stress training programme for workers exposed to heat;
• provide cool drinking water supply near work areas;
• ensure cold water, ice packs or water spray on standby for emergency response; and
• provide suitable clothing that can mitigate or protect workers from excessive heat stress.

3            In addition to the mandatory requirements, MOM has also introduced a new recommended practice that employers provide shaded rest areas that are well ventilated and well insulated or cooled. (See link for the infographic on the Updated Heat Stress Measures for Outdoor Work.)

4            The enhancements were developed in consultation with tripartite partners, industry stakeholders and relevant government agencies. They complement existing requirements under the Heat Stress Management Framework, including Wet Bulb Globe Temperature monitoring, regular hydration, provision of adequate rest breaks under shade, heat acclimatisation and emergency response planning. Together, they strengthen employers' management of heat stress risks by improving worker preparedness, effective hydration, emergency response and workplace conditions.

5            Minister of State for Manpower, Mr Dinesh Vasu Dash said, "Heat stress is an increasingly important workplace safety and health issue, particularly for workers carrying out outdoor work. As part of Singapore’s broader efforts to strengthen our resilience to rising temperatures, employers must also take proactive steps to protect workers from heat-related risks. These enhanced measures provide clearer expectations for employers while strengthening protection for workers. I encourage employers to use the next three months to review their workplace practices and put the necessary measures in place before the enhancements take effect on 1 December 2026. Better management of heat stress not only safeguards workers' health and well-being, but also helps employers reduce downtime, maintain productivity and support business continuity. "

6            MOM will continue to support employers through outreach and engagement, and work with tripartite partners and industry stakeholders to facilitate implementation of the enhanced measures and strengthen protection for workers against heat-related risks.
