Selangor tightens air quality controls with school closures threshold

Selangor authorities have introduced stricter environmental controls to combat air pollution, including a prohibition on open burning activities across the state. The regulations form part of a broader strategy to manage air quality during seasonal haze and pollution events that periodically affect the region.

Under the new framework, schools will be ordered to close if the Air Quality Index reaches 200 or higher, a threshold typically classified as unhealthy. The closure directive is designed to minimize exposure for students and staff during periods of hazardous air conditions.

Public health authorities have also issued guidance recommending residents to limit strenuous outdoor activities when air quality becomes unhealthy. Officials have advised the public to remain indoors during severe pollution episodes to reduce respiratory health risks.

The measures come as Malaysia continues to address seasonal air quality challenges, which often intensify during the dry season when neighboring regions experience forest fires. Selangor, as the nation's most populous state, has made air quality management a priority given the large population potentially affected by pollution events.
