Outdoor event organizers in Singapore prepare for potential annual haze

AI-summarized · Neutrality-checked

Event organizers in Singapore, including those for the Formula 1 Grand Prix, implemented contingency plans for the 2026 haze season following forecasts of a heightened risk for severe transboundary smoke from forest fires in Indonesia. The Meteorological Service Singapore indicated that persistent dry conditions in Sumatra and Kalimantan could intensify fires, potentially pushing the Pollutant Standards Index (PSI) above unhealthy levels. The interagency Haze Task Force, chaired by the National Environment Agency, updated response protocols that include medical support, mask distribution, and operational adjustments for outdoor activities and workplaces.

Consequences

If the PSI levels exceed 100, authorities and event organizers will likely trigger tiered response measures to mitigate public health risks, which may involve scaling back outdoor work and restricting large-scale public events. These actions serve to protect spectators, employees, and vulnerable populations from the effects of poor air quality.
