Residents throughout the Southern Tablelands are being urged to monitor symptoms arising from a dust storm heavily impacting the area.
Southern NSW Local Health District (SNSWLHD) issued a warning for people that may be affected by the poor air quality.
People with chronic respiratory and cardiovascular conditions such as asthma, chronic bronchitis, emphysema and heart disease are urged to monitor their symptoms.
Dust can aggravate existing heart and lung conditions, as well as causing itchy or burning eyes, persistent cough, throat irritation and runny nose.
People with chronic conditions need to be vigilant with their treatment programs as symptoms can persist for several days after the dust is inhaled, director of public health Tracey Oakman said.
"If you are on home oxygen treatment, continue as prescribed and if breathlessness worsens, contact your general practitioner," Mrs Oakman said.
"If possible, stay in air-conditioned premises where filtration systems can help to reduce dust particles in the air.
"People with asthma or a lung condition who develop symptoms such as shortness of breath, coughing, or wheezing, should follow their asthma or chronic obstructive pulmonary disease action plan."
The advice is if the symptoms do not settle, see your GP.
In case of an emergency always remember to dial triple zero. For more information, visit the NSW Health air quality web page at health.nsw.gov.au.
