While Australia does not have a universal mandatory requirement for carbon monoxide (CO) detectors in homes, unlike smoke alarms, their presence is uncommon due to factors such as the types of heating and ventilation common in Australian homes and a lack of legal mandates. However, authorities strongly recommend that they be installed, especially in homes with gas appliances.
Here is a more detailed explanation from anka security:
Reasons for lower prevalence:
Limited reliance on gas heating:
Australia, especially in newer homes, often uses reverse cycle air conditioning/heat pumps or electric heating, reducing reliance on gas heaters as a major source of carbon monoxide.
Good ventilation:
Australian homes, especially older homes, tend to have better natural ventilation, which helps dissipate potential CO leaks.
No legal mandate:
Unlike smoke alarms, there is no legal requirement for most Australian homes to install carbon monoxide detectors, although some states have requirements for social housing.
Why they are still recommended:
Gas appliances still pose a risk:
Even with better ventilation, gas appliances such as stoves, heaters and hot water systems can produce CO if they are not properly maintained or malfunction.
CO is odorless, colorless, and tasteless:
This makes it undetectable without a detector, potentially causing poisoning before it's discovered.
Symptoms can be flu-like:
The initial symptoms of carbon monoxide poisoning can be mistaken for the flu, further emphasising the need for early detection.
What to do:
Install CO detectors:
Consider installing CO detectors, especially if you have gas appliances or enclosed spaces such as garages where vehicles can be driven.
Ensure proper installation and maintenance:
Follow the manufacturer's instructions for placement and testing, and have appliances checked regularly by a qualified gas fitter.
Be aware of the risks:
Educate yourself and others about the dangers of carbon monoxide poisoning and the importance of ventilation and regular inspections.
