Safety Information

When air quality is hazardous: stay indoors with windows closed, and run a filtered air purifier if you have one. Avoid outdoor exercise. Children, older adults and anyone with heart or lung conditions are affected first and worst — an N95 respirator helps outdoors, a cloth mask does not.

Series begins 8 March 2026. Comparisons refer to that period only. Collection gap: 14-26 August 2026.
