What it contains

Smoke consists of particles that weren’t burnt completely. When the particles fall from the air, they collect on surfaces as soot and ash. This fact sheet contains information about the health risks of ash, and how to clean up ash after a fire has been extinguished. For information about ash and water tanks, see bushfires and your private drinking water supply.
