Bushfire smoke

Smoke from bushfires, planned burns, and other sources can impact air quality. Bushfire smoke contains toxic gases such as carbon monoxide and nitrogen oxides, and particles, all of which can be hazardous to your health. Small particles in smoke affect the lung’s ability to breathe and cause coughing, sore throat and runny nose. For healthy adults, these effects usually disappear quickly once they move away from the smoky conditions. However, exposure to smoke over long periods of time (several weeks to months) during bushfire seasons can increase the risk of lung disease, anxiety and distress.

People with heart or respiratory conditions (including heart failure and high blood pressure, asthma, bronchitis, emphysema and chronic obstructive airway disease) are more sensitive to the effects of breathing in smoke. Smoke is also more likely to affect children, pregnant women and older adults.

Fine smoke particles can contribute to inflammation and narrowing of blood vessels in the heart and trigger bronchospasm in the windpipes (bronchi) of the lungs, making breathing more difficult. Farmers or agricultural workers with pre-existing heart and lung conditions should avoid exposure to bushfire smoke where possible.

Reduce your risk of bushfire smoke exposure:

• Stay indoors. If you can’t stay indoors and you need to be outside – wear a P2/N95 dust mask that has been properly fit-tested.
• Wear an AS/NZS approved P2 face mask. Note: P1 dust/surgical masks, handkerchiefs or bandannas do not filter out the fine particles of smoke and will not protect your lungs from smoke as effectively as a P2/N95 dust mask. It is important to note that whilst a P2/N95 dust mask will protect you from smoke, it can make it more difficult to breathe. If you do have a lung/heart or medical condition, you should seek medical advice about wearing a mask long before you actually need one. P2/N95 face masks with a valve will feel less claustrophobic to breathe through.
• Protect your eyes. The small particles in smoke will also irritate and cause sore, itchy eyes. Wearing a non-ventilated goggle or a smoke visor/goggle combination will protect and assist with visibility.
• Reduce physical activity outdoors. If you need to exercise access indoor gyms and pools with good air quality.
• Quit smoking as it makes you more sensitive to air pollution.
• Trust your senses. If you smell and see smoke, the risk of high levels of exposure is likely. If you feel difficulty breathing, wheezing or tight chest, seek urgent medical help and call triple zero (000).

On days of High Fire Danger Risk (FDR):

• Keep well and stay well hydrated
• Follow local Fire Authority news and advice
• Follow your fire plan to protect yourself from the threat of bushfires and smoke
• Follow air quality information – be aware of the daily Air Quality Index (AQI)
• If you have a lung or heart condition and are on prescribed medication, make sure you update your management action plan, take your medication, and ensure you have enough medications for several days in case you can’t re-stock your supply easily.

It is crucial you remove yourself from smoking, seek medical help or Call triple (000) if you start to experience the following:

• difficulty breathing
• coughing
• chest tightness
• chest pain
• palpitations
