Singapore’s Ministry of Manpower (MOM) is strengthening protections for outdoor workers against heat stress, making four measures mandatory under an enhanced Heat Stress Management Framework from 1 December 2026.
The changes are part of Singapore’s wider efforts to build resilience against rising temperatures and address growing workplace safety and health risks linked to heat exposure. Employers will have three months to prepare and implement the new requirements before they take effect.
Under the enhanced framework, employers must establish a heat stress training programme for workers exposed to heat and ensure cool drinking water is readily available near work areas. They will also be required to keep cold water, ice packs or water spray on standby for emergency response.
Employers must additionally provide suitable clothing designed to mitigate or protect workers from excessive heat stress.
These four measures were previously recommended under Singapore’s Heat Stress Framework for Outdoor Work and have already been widely adopted across workplaces. MOM said they are now being elevated to mandatory requirements to ensure more consistent implementation across industries.
The ministry has also introduced a new recommended practice for employers to provide shaded rest areas that are well ventilated and well insulated or cooled.
The enhanced measures complement existing requirements under Singapore’s Heat Stress Management Framework, including Wet Bulb Globe Temperature monitoring, regular hydration, adequate rest breaks under shade, heat acclimatisation and emergency response planning.
Together, the measures are intended to strengthen employers’ ability to manage heat stress by improving worker preparedness, hydration, emergency response and workplace conditions.
Minister of State for Manpower Dinesh Vasu Dash said heat stress is becoming an increasingly important workplace safety and health issue, particularly for employees working outdoors. He urged employers to use the three-month transition period to review existing practices and implement the enhanced measures ahead of the December deadline.
MOM said stronger heat stress management can not only protect workers’ health and well-being but also help employers reduce downtime, maintain productivity and support business continuity.
The enhancements were developed following consultations with tripartite partners, industry stakeholders and relevant government agencies. MOM will continue outreach and engagement with employers and work with industry partners to support implementation.
