NSW Health is warning people to be aware of the health risks as a large dust storm moves across NSW, bringing increased dust to Sydney and the east coast.

Director of Environmental Health, Dr Richard Broome said people with chronic respiratory and cardiovascular conditions should cut back or reschedule strenuous outdoor activities.

“Dust may aggravate existing heart and lung conditions and cause symptoms like irritated eyes and a cough,” Dr Broome said.

“People with conditions including asthma, chronic bronchitis, emphysema and heart disease should monitor their symptoms throughout the day.

“People with asthma should follow their Asthma Action Plan and it’s a good idea to make sure you carry your reliever puffer with you.”

Air quality in the Sydney basin is expected to worsen during the day before a cold front brings rain later on Wednesday afternoon.

In northern parts of the State levels of dust are forecast to increase in the afternoon and evening.

“Symptoms can occur for several days after dust is inhaled, so people with chronic conditions need to be vigilant with their treatment programs,” Dr Broome said.

If symptoms do not settle, seek medical advice and in the case of an emergency always remember to dial triple zero.
