People in Sydney are being warned to stay inside due to “hazardous*” air quality.
The city has been blanketed* in smoke from a large fire burning northwest of Sydney. The NSW Rural Fire Service said smoke from an enormous bush fire burning in the Gospers Mountain was being blown across much of Sydney.
The RFS said the smoke would start to clear as the day warmed up on Tuesday and winds increased.
“However due to north westerly winds smoke from this fire is likely to affect Sydney over the coming days,” the RFS said in a statement.
A poor air quality alert has been issued by the Department of Planning, Industry and Environment due to elevated particle* (PM2.5) levels in Sydney.
At 9am on Tuesday the reading stood at 2334 in Sydney’s North-West — almost 20 times worse than Jakarta in Indonesia and Beijing in China.
The dangerously high reading makes the city’s air quality the worst in the world and twice as bad as Kolkata, India, which today sits at 999, according to the World’s Air Pollution: Real-time Air Quality Index.
As bushfires continue to burn across NSW and Queensland and with other states preparing for increased fire risk in coming days, it’s important we all know how and why we should avoid breathing in smoke.
Residents are advised to stay indoors, with windows and doors closed, or stay in airconditioned buildings, 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. Use a mask rated either P1 or P2. These are available from hardware stores.
P2 masks are more effective in blocking the finest particles, however any mask has to be worn correctly over the nose and mouth to protect you.
WHY SMOKE IS BAD TO BREATHE IN
Smoke from bushfires is a mix of solid particles, water vapour and toxic* gases such as carbon monoxide, carbon dioxide and nitrogen oxides.
Smoke can irritate your eyes, nose and throat.
When you breathe in, small particles and toxic gases can go deep into your lungs.
If you have asthma or heart or lung problems, smoke can make these conditions worse.
Even if you are healthy, breathing in smoke irritates your airways and lungs, causing you to cough, have a sore throat or a hoarse voice.
Aside from the discomfort* of a cough or sore throat, smoke inhalation* can lead to a medical emergency.
Inhaled smoke causes the lining of airways and lungs to swell. The swelling reduces the amount of oxygen you are able to take into your bloodstream.
If you are not able to take in enough oxygen, you could get a headache or feel faint or get chest pains because there is not enough oxygen getting to the heart.
If you or someone you are with is having trouble breathing or feeling faint, tell an adult and call 000 for an ambulance.
