What to do
- Keep windows and doors closed. An air purifier with a HEPA filter cleans indoor air.
- Outdoors for hours? A well-fitted N95 mask filters fine smoke. Surgical masks do not. Short trips do not need one.
- Check on elderly relatives and neighbours.
- Breathless, chest pain or dizzy? Seek medical attention.
