As global temperatures continue to rise, Singapore is stepping up to ensure the health and safety of its outdoor workers with innovative measures tailored to their needs.

Recognising the urgent need to address the risks posed by higher temperatures, the Ministry of Manpower (MOM) launched comprehensive heat stress regulations in October 2023. This initiative reflects Singapore’s commitment to keeping its workers safe in an increasingly harsh environment.

These safety measures were developed collaboratively, drawing on the expertise of the Ministry of Health's Heat Stress Expert Panel, government agencies, and employer organisations. This partnership exemplifies Singapore's strong sense of community and commitment to the common good.

Following the introduction of these measures, MOM conducted active workplace inspections to ensure compliance. Out of over 70 inspections, 23 firms were found to be falling short of the new standards, necessitating prompt corrective action.

Understanding the heat stress guidelines

Singapore's strategy to combat occupational heat exposure is based on monitoring the Wet Bulb Globe Temperature (WBGT), an excellent tool for assessing heat stress levels by combining several environmental factors.

Employers are required to check the WBGT every hour during outdoor operations. If temperatures reach 32°C or above, it is mandatory for workers to take at least 10-minute breaks in shaded or cool areas every hour.

The guidelines further emphasise:

• The introduction of a buddy system to help workers monitor each other for signs of heat-related stress
• Regular hydration, with workers encouraged to drink water at least every hour
• Adequate acclimatisation time for new or returning workers, allowing them to adjust to outdoor conditions gradually over a minimum of seven days.

Long-term safety and health strategies

Singapore’s heat stress policy extends beyond immediate measures to cool down. It also encourages:

• Scheduling strenuous tasks during cooler parts of the day
• Creating comfortable rest areas near work zones to reduce heat exposure
• Utilising fans and air coolers to keep work and rest areas cool
• Providing workers with lightweight, breathable clothing to help regulate body temperature

Forward-thinking in climate adaptation

Singapore's proactive measures align with global efforts to address occupational hazards associated with climate change. With thousands of workers worldwide affected by heat stress each year, Singapore's strategy not only addresses immediate health concerns but also resonates with the United Nations' call for long-term climate action.

By tailoring its policies to meet specific needs, the city-state not only adheres to best practices but also sets an example for how to protect workers in the face of global environmental changes. This commitment ensures Singapore's leadership in worker safety and climate resilience, fostering a caring and proactive community.
