Malaysia Ends Serian Haze Emergency as Air Quality Improves

Emergency Lifted in Serian as Haze Levels Decline
On September 7, the Malaysian government terminated the local haze emergency that had been in force for the Serian district of Sarawak. The decision followed a drop in the Air Pollutant Index (API) to 222, well below the hazardous threshold of 300. The emergency had been declared on September 4 after API readings surged to 519, surpassing the 500 level that triggers a Level 5A alert under the National Haze Action Plan (NHAP).
Background & Context
The haze originated from forest and peat fires in Indonesia’s Kalimantan region of Borneo. Transboundary smoke drifted northward across the South China Sea, reaching Sarawak and prompting school closures and health warnings. Satellite imagery captured on September 1 by National Aeronautics and Space Administration’s (NASA)’s Aqua instrument showed extensive thermal anomalies across Indonesian Borneo, illustrating the scale of the burning.
Data & Statistics
- September 4: API in Serian peaked at 519, exceeding the 500 emergency trigger by roughly 4 percent.
- September 7: API fell to 222, below the hazardous level of 300 but still classified as “very unhealthy.”
- Nearby districts recorded API values still in the “very unhealthy” range: Samarahan at 233, Kanowit at 221, and Kuching at 299.
- Nationwide, 18 other areas reported “unhealthy” API levels during the episode.
Official Statements & Responses
The Prime Minister’s Office announced that the King, Sultan Ibrahim Iskandar, gave consent to end the emergency after advice from Prime Minister Anwar Ibrahim and Sarawak Premier Abang Johari Openg, together with agency reports showing improved air quality.
Sarawak Disaster Management Committee (SDMC) Chairman Datuk Amar Douglas Uggah Embas reiterated that the federal and state governments will continue close monitoring. He noted that the emergency measures—closure of non-essential workplaces within a 20-kilometre radius of Serian—were intended to protect public health, not to impose a lockdown.
The Department of Environment (DOE) announced heightened monitoring and enforcement actions, including patrols of high-risk peatland and forest areas, drone flights for real-time assessment, and a public hotline for reporting open-burning incidents.
Why It Matters
Although the emergency declaration has been lifted, API readings remain at “very unhealthy” levels in several districts, posing ongoing health risks, especially for children, the elderly, and those with respiratory conditions. The government’s continued advisories to wear N95 or equivalent masks and to stay indoors aim to mitigate exposure. The episode underscores the persistent challenge of transboundary haze, which recurs each dry season and is linked to difficult-to-extinguish peat fires.
What’s Next
- Monitoring: Federal and Sarawak authorities will keep air-quality stations active and issue regular updates.
- Public Guidance: Residents are advised to limit outdoor activities, use N95 masks when exposure is unavoidable, and follow instructions from health officials.
- Enforcement: DOE will maintain patrols and drone surveillance of fire hotspots, and the public can report violations via the 999 emergency line or the DOE toll-free number 1-800-88-2727.
The lifting of the emergency reflects a measurable improvement in air quality, yet the situation remains fluid, and authorities stress that vigilance will continue until API levels return to safe ranges.
