The Gospers Mountain fire in the Wollemi National Park, which had blanketed the Mudgee area with smoke recently, has burned over 10,000 ha but is being controlled.
Combined NSW Rural Fire Service and remote area firefighting crews from the National Parks and Wildlife Service have been working to contain the fire, supported by seven aircraft and two bulldozers.
As of Tuesday it has burned 10,279 ha in steep terrain. No properties or populated areas have come under threat.
Around 7mm was received in the area of the fire overnight on Sunday/Monday, which did help slow the spread.
Heavy smoke from the fire settled over extensive parts of the Mid-Western Regional Council area last week. More may be experienced as work continues to extinguish hot spots and burning trees over a large area once the fire is contained.
On smokey days people with health issues are encouraged to take appropriate precautions.
NSW Health recommends; staying indoors, with windows and doors closed, or stay in air-conditioned premises, if possible; avoid vigorous exercise, especially if you have asthma or a lung condition; cover your nose and mouth with a mask designed to filter fine particles (rated either P1 or P2); postpone outdoor events or seek shelter in air-conditioned premises or a clean-air room, if one is available.
If you have asthma or a lung condition and you develop symptoms such as shortness of breath, coughing or wheezing, follow your asthma or COPD action plan.
If symptoms do not settle seek medical advice. If you are on home oxygen treatment, continue as prescribed and if breathlessness worsens contact your doctor.
