Should I be worried about smoke haze?

16 January, 2020

Australia’s unprecedented bush fire crisis has devastated many small towns and rural communities. Fire and smoke are the immediate risk in bush fire areas, but pollution levels have also soared in places beyond the immediate fire zone. The smoke haze blanketing some cities has stretched as far inland as Broken Hill. At one point the smoke even reached New Zealand.

Is smoke haze hazardous?

Yes, according to the Australian Medical Association (AMA) President, Dr Tony Bartone. He says we should be taking extra precautions. ‘With denser smoke haze and longer periods that people endure smoke inhalation, there is a much higher risk that previously healthy people will face developing serious illness.’

Why is it dangerous?

Smoke haze contains microscopic particles that can enter the lungs. Children, pregnant women and the elderly are more at risk, as well as people who already suffer from asthma or any form of respiratory disease.

People with heart disease or cardiac risk factors like high blood pressure should also be cautious because the microscopic particles can irritate the cardiovascular system, constricting blood vessels and increasing the chance of a heart attack.

Those with no pre-existing heart or lung conditions are not automatically immune. If you develop breathlessness, wheeziness, a tight chest or a persistent cough the AMA recommends you seek medical attention immediately.

How can I reduce the risk?

Check air pollution levels for your area. On days when levels are high, or when you can see or smell smoke, take preventative measures.

  • Carry any medication with you at all times.
  • Avoid exposure wherever possible.
  • Limit the time you spend outdoors.
  • Avoid engaging in strenuous outdoor activities.
  • If you’re caught outside, seek shelter in a modern building with air conditioning.
  • If you have recirculating air conditioning at home, close all doors and windows and switch it on.
  • Air purifiers with HEPA (high efficiency particulate air) filters can help clean the air inside your house, although they can be expensive.
  • Most modern vacuum cleaners are fitted with a HEPA filter. Vacuum regularly to remove dust and smoke particles that may have settled.

Should I wear a face mask?

If you’re going to wear a face mask, make sure it’s one that works and is correctly fitted. Only certain masks are effective against smoke pollutants. Paper masks (the kind you often see dentists wearing) won’t offer protection against smoke. Look for masks labelled P2 N95 or P100. Your local pharmacy or hardware store may stock them.

The label refers to the percentage of small particles the mask can filter. N95 can filter 95 percent and P100 can filter an impressive 99.7 percent of particles.

Make sure the mask forms a tight seal against your face so there are no air gaps around the side.

Masks may not fit correctly on small children. The best advice is to avoid exposure.

I joined as a CBHS member in 1978. Through many health events and challenges CBHS has always been there for me and my family. Their exceptional service over this time has always been appreciated.

I've not long joined CBHS from another fund, but so far I've been impressed by the super helpful and friendly staff, the higher claim limits and rebates at a very competitive premium, and how easy it is to lodge manual claims through the app. Thanks CBHS - you've won me over! 😃

What Our Members Think

I have been with CBHS since I began at CBA 15 years ago...Now I have three beautiful children, one who has a disability. Our top extras cover has been really essential for his early intervention. I do love the ease of claiming online.

What Our Members Think

I am relatively new to CBHS and am loving it already. I worked for a CBA subsidiary a long time ago but was still eligible to join. So much better that the for-profit funds - our premium is only a little more and we pay a lower co-contribution and get great benefits. I am loving the massage rebate for my partner and gym rebate for me!

I'm extremely happy with CBHS! I have been a customer for about six years. I think the price is reasonable. And i would refer you to my family and friends any day. Thank you CBHS!!!

What Our Members Think

Love CBHS as I never have to doubt that they've got my back when I need it. Been through other insurers who have limited options or limits, yet cost the same or more.
