Carbon monoxide poisoning: silent but deadly

Call it gallows humour, but that is the most accurate way to describe CO poisoning. Carbon monoxide is a colourless, often unscented gas that can leak for hours without detection. Highly ignitable and poisonous, it is a serious threat that must be handled professionally.

All gas-fed appliances can leak carbon monoxide. That includes gas stoves, ovens, BBQs, gas heaters and gas ducted heating.

Inner City Plumbing is one of Melbourne’s most trusted carbon monoxide detector specialists. We are trusted by countless homeowners and businesses to perform carbon monoxide testing and ensure their loved ones, staff, and clients are safe.

Accidents happen. The best you can do is prepare for them as well as you can. Safely installed and properly maintained gas appliances dramatically reduce the chances of a CO2 leak, which is why we use premium tools and components in our work.

Frequently asked questions

Carbon monoxide leaks can be extremely difficult to identify without professional equipment. Here are some signs to look out for:

  • Your gas flames burn yellow or orange instead of blue
  • Your gas fires may be hard to light or seem to burn very slowly

Often, the clearest signs of a carbon monoxide leak are its effects on you. You may have a CO leak if you feel any of the following symptoms around your gas appliances:

  • A sudden headache or migraine
  • Tiredness, dizziness and confusion
  • Difficult breathing
  • Chest pains

Here are four tips to keep yourself safe from CO poisoning:

  • Have your gas appliances tested for leaks once a year
  • Have your chimneys and flues professionally cleaned once a year
  • Ensure rooms with gas appliances are well-ventilated
  • Check the colour of the flames of your gas appliances. They should be blue; if the flames are orange, immediately book a carbon monoxide test.

If you believe you have a CO leak, do not attempt to fix the leak yourself. Only a licensed gas fitter can fix leaks safely. Instead, follow these steps:

  • Immediately extinguish any nearby flames
  • Turn off any gas appliances
  • Open any windows and doors to improve ventilation
  • Switch off the gas from the mains, or inform your site manager and request that they switch off the gas
  • Evacuate the area and call Inner City Plumbing

Our emergency team will arrive to test for gas and carbon monoxide leaks within the hour.
