THE ACT Rural Fire Service is conducting a hazard reduction burn tonight at Weston Creek, on behalf of the National Capital Authority.

The burn is to involve six small organic material heaps in a cleared paddock between Lady Denman Drive and Lake Burley Griffin, east of the National Zoo and Aquarium.

The ACTRFS will have six units involved with a total of 23 firefighters.

Temporary smoke cover may occur and will be visible from the Tuggeranong Parkway. Every effort is made to conduct the burns in weather conditions that will minimise the impact of smoke in the area.

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.
