The same 4pm update placed Tebedu at 399, Lubok Antu at 396 and Sri Aman at 334, also hazardous. Sarikei, Sibu and Mukah were in the very unhealthy range at 277, 243 and 216 respectively. API readings move through the day, so the afternoon figures should not be treated as a forecast for tonight.

Sarawak’s disaster committee said there was no need for an emergency declaration yet. If a local reading reaches 500, the matter would first be taken up with the National Disaster Management Agency, and any emergency would apply only to the affected locality—not the whole state. Offices, schools and activities in that locality would be required to close under such a declaration, apart from essential services.

For areas at API 201 and above, residents are advised to limit outdoor exposure and wear an N95 mask when going out, or at least a three-ply mask if one is unavailable. Children, older people and those with breathing problems should take extra care and seek medical help if symptoms worsen.
