Update two - Structure fire at Hume

Fire crews continue to work on bringing the fire under control.

Firefighters have protected the perimeter of the property to ensure the fire doesn't spread to adjoining buildings.

Smoke may spread over the inner south of Canberra.

ACT Fire & Rescue HAZMAT specialists are monitoring the air quality.

The Health Directorate advises that people with asthma, other chronic respiratory and/or chronic cardiac diseases should not perform vigorous exercise and should stay inside if affected by the smoke. People with asthma in particular should continue their medication and consult their general practitioner if they have any difficulties.
