Health risks from indoor gas appliances | RACGP

Cooking and heating with gas is common in Australian homes and is a risk factor for several important health problems; however, there is little awareness of these risks among doctors or the public. Gas stove use is estimated to cause 12% of childhood asthma in Australia.



The aim of this article is to help general practitioners identify when gas combustion products such as nitrogen dioxide might be contributing to asthma in children and adults and to alert them to the risks of carbon monoxide (CO) poisoning, which can be hard to diagnose.


There are excellent alternatives to the use of gas in domestic appliances and some simple behavioural changes that can reduce exposure in situations where appliances cannot yet be removed. CO poisoning can be insidious. Mild exposure can cause headache, nausea, vomiting, dizziness, malaise and confusion, so it can be mistaken for common conditions such as influenza or gastroenteritis. The COMA mnemonic is clinically useful. Increased awareness of these issues can provide patients with safer and healthier living environments.

Sixty five per cent of houses in Australia use gas for cooking or heating, and while this was once seen as clean and cheap, we now understand that gas combustion products have substantial negative health impacts, and the widespread use of gas in domestic settings is an avoidable health risk.1 The two most important gas-related health impacts are the respiratory effects of nitrogen dioxide (NO2) and the toxicity due to acute or chronic exposure to carbon monoxide (CO). This article examines the health impacts of indoor exposure to gas combustion products and what patients could do to minimise these.
