Earlier within the pandemic, residences have been described as “vertical cruise ships” as a result of ease of unfold of the coronavirus between many individuals sharing confined areas. However residences are nothing like cruise ships as a result of residences don’t have frequent air flow provide and consuming areas, amongst different issues. The “cruise ship” description is inaccurate, if vibrant.
Since then, we’ve realized extra about how SARS-CoV-2, the virus that causes COVID-19, spreads through the air we breathe and the significance of excellent air flow in a variety of settings.
Listed below are 9 issues you are able to do to minimise your threat of catching the virus should you reside in an condo.
1. Keep away from poorly ventilated indoor areas
Apart from getting vaccinated, step one to minimising your threat of catching the virus is to keep away from poorly ventilated indoor areas with out utilizing a masks (see additionally level 4).
This reduces the chance of sharing air with neighbours and reduces dangers related to frequent amenities, equivalent to lifts, gyms and rubbish areas.

2. Watch laundries and indoor rubbish areas
However you’ll nonetheless must do your laundry and dispose your rubbish. Shared laundries, gyms and indoor rubbish areas are an apparent threat, notably if poorly ventilated.
So maybe organize a rota to present folks entry at set instances and guarantee at the least one hour elapses between use to permit for sufficient air modifications.
The place there’s a mechanical air flow system, guarantee ducts and followers are working. The place there are home windows, guarantee they’re open.
Think about putting in a mixed washer-dryer in your kitchen or lavatory.
3. Ask strata about shared basement garages
These are sometimes mechanically ventilated by a system with followers that solely function when carbon monoxide is sensed. With fashionable autos, the air flow might not run usually, leading to poor air flow.
It might be doable to override the sensors; request the strata to ask individuals who preserve the system.

4. Put on a masks earlier than opening the door
Make sure you and all members of your family placed on a masks earlier than opening the door to your condo. Many individuals are used to carrying surgical or material masks.
Nevertheless, OzSAGE, an unbiased group of researchers offering evidence-based recommendation concerning the pandemic, recommends an N95 masks, which offers higher safety towards the Delta variant.
You must put on this masks when receiving deliveries or letting in guests, in addition to when leaving the condo to maneuver by way of shared areas.
The place there’s an outbreak, carrying a masks in shared areas might be obligatory. Even when it’s not, you may nonetheless request your strata company to ask residents and guests to put on a masks, and to require this of contractors.
5. Ask concerning the lifts
Lifts are a selected hazard in taller buildings. So ask your strata concerning the following:
limiting elevate capability to 1 particular person per 2.5 sq. metres. If a high-efficiency particulate air (HEPA) air purifier can function repeatedly within the elevate, the density limits could also be relaxed if well being orders permit
ensuring lifts go to an unoccupied stage with the doorways open when not in use. Some lifts might be programmed to do that; the agency servicing the elevate will advise.
6. In the event you can scent your neighbour’s cooking …
Some condo buildings in Australia have gaps on the prime of partitions between adjoining residences. This defective “fireplace isolation” means fireplace can probably unfold between residences. In principle, so can shared air containing contaminated aerosols.
So should you can scent your neighbour’s cooking or one thing worse, you might be sharing their air. In the event you suspect an air leakage and are unable to do something about it within the quick time period, utilizing a HEPA air air purifier in your condo will scale back your threat.

Open your home windows to extend air flow in your condo when guests or upkeep workers are there. Put on a masks if the customer is just not double-vaccinated or should you’re in any other case involved.
There may be comparatively little proof exhibiting cross contamination between exterior home windows of neighbouring residences, which is reassuring.
However, in case you are opening a window, opening one onto your balcony poses much less of a threat (because the air is best dispersed) than opening one instantly above or under one other condo’s window.
8. Take a look at your service riser
Service risers are the vertical ducts that run pipework for plumbing and air flow by way of kitchens and bogs in condo buildings.
Hong Kong analysis suggests such ducts have been linked with infections between a number of flooring of the Amoy Gardens buildings through the SARS outbreak.
In Australia, many condo blocks have rudimentary sealing to those service risers. So verify inspection panels are sealed in place and that pipes are sealed the place they enter any cavity. You may must hunt inside kitchen or lavatory cabinets to seek out these.
Gentle an incense stick (or related) to see if the smoke wafts round to point air is blowing into or out of service risers. However watch out to not set off the smoke alarm whereas testing. If doubtful, cowl up the smoke alarm on the ceiling with plastic wrap and a rubber band, however don’t overlook to take it off afterwards.
In the event you’re helpful, you should buy fire-rated increasing foam or different merchandise from a ironmongery store to seal these gaps. In the event you’re not, contact the strata to debate the work. And don’t let any waste traps dry out.
9. Repair damaged exhaust followers
One other potential supply of leaks and cross contamination is shared lavatory and kitchen air flow techniques that function completely. These are extra frequent in older buildings and you’ll recognise them by steady exhaust noise from vents within the lavatory, bathroom or kitchen.
Guarantee followers are working usually and if the fan stops, guarantee it’s repaired promptly.
Newer residences might have self-contained exhaust followers that function solely when the sunshine or a fan swap is operated. The chance of cross contamination with such a set up is low.
