Malaysia to shut schools, ban gatherings as haze crisis deepens

Malaysia will implement sweeping restrictions on schools and public activities if the Air Pollution Index (API) exceeds 200, signalling a significant escalation in response to deteriorating air quality across the country.

Under the contingency framework, all schools nationwide would be shuttered once the API surpasses the 200 mark, which falls within the "unhealthy" category according to Malaysian air quality standards. Simultaneously, public gatherings and outdoor events would be prohibited to minimise health risks to residents.

The decision reflects heightened vigilance over air pollution, which frequently spikes during the dry season when transboundary haze from forest fires in neighbouring Indonesia drifts into Malaysian airspace. Such episodes have periodically affected air quality throughout South and Southeast Asia, including Singapore.

Malaysian health officials have previously warned that prolonged exposure to hazardous air quality poses serious respiratory and cardiovascular risks, particularly for vulnerable populations including children, the elderly, and those with pre-existing conditions.

The government has not announced a specific implementation date, suggesting the measures will be activated based on real-time API readings monitored by the Department of Environment.
