Carbon Monoxide Safety Program
Learning module and exam
If you are registered or licensed in the main class of gasfitting or the specialised classes of Type A appliance conversion and/or servicing work, you will need to complete an online learning to retain your accreditation in these classes.
All registered or licensed gasfitters will receive an email about the learning module by Friday, 21 September 2018.
Practitioners solely registered or licensed in Type B gasfitting work or Type B gasfitting advanced work do not need to complete the online learning module.
What to do when you detect carbon monoxide spillage
If you detect any rise in the level of carbon monoxide above your background reading, you should find and eliminate the cause of the spillage.
If this is not possible, or you are unable to eliminate the cause of the spillage, the appliance must be isolated with the consent of your client.
If your client refuses to allow you to isolate their gas appliance, you must contact Energy Safe Victoria on 1800 652 563 (select option 5).
When calling ESV, please ensure you supply the following information:
- Your name, licence number and mobile telephone number;
- Your customer’s name, address and telephone number;
- The type of heater spilling carbon monoxide; and
- The level of carbon monoxide spillage detected (in parts per million).
An ESV inspector will contact you soon after receiving these details to obtain further information. They will then contact your client in an attempt to resolve the matter.
As part of the resolution, ESV may offer to carry out an additional inspection, re-iterating the dangers and consequences of carbon monoxide spillage. They will also inform your client that their gas supplier must withdraw supply to the premises if the heater is found to be unsafe.
What to do when there is no spillage, but your client won’t let you rectify a negative air pressure situation
When you service an open-flue gas heater and detect negative air pressure, you have a responsibility to make the situation safe and inform your client of your findings.
To help you explain the potential dangers of carbon monoxide and the steps needed to overcome negative pressure, the VBA and Energy Safe Victoria have prepared an advice letter, which you should fill in and provide to your client after completing an inspection and service.
In all cases, clearing existing vents and installing additional ventilation are the recommended solutions for overcoming negative pressure. If this is not possible, check with your client to see whether they are happy for you to isolate their heater.
Sometimes, though, a client may not want you isolating their gas heater or installing additional ventilation in their home. In such cases, you should take the following action:
- Hand your client the advice letter and re-iterate the potential dangers of carbon monoxide and the effect of negative pressure.
- Remind your client of the need to install additional ventilation in their home to overcome the effect of negative pressure.
- Inform your client that you will be notifying the VBA of the situation, and that the VBA will contact the client directly.
- Notify the VBA as soon as possible by emailing email@example.com or by calling 1300 815 127 during business hours. Make sure you supply your client’s contact details, site address and heater details.
Once you have notified the VBA of your actions regarding a client’s gas appliance, your job is done. The VBA will take over and work with your client to resolve their negative air pressure situation.
Please note: The VBA will not take enforcement action against a registered or licensed gasfitter where we have been appropriately notified of the situation regarding your client’s gas heater.

Negative Pressure and Carbon Monoxide Spillage Training Video
To support all Victorian gasfitters and Type A appliance servicing plumbers, the VBA has produced a short instructional video demonstrating the steps required to correctly test for negative air pressure and carbon monoxide spillage.
The video guides practitioners through these important tests, outlining faults common to gas heaters and demonstrating how to identify and combat negative air pressure.
It also provides practitioners with information they should be aware of when testing for carbon monoxide spillage. This includes safety tips to be used when carrying out this important work.
Practitioners should refer to this video before servicing or testing open-flue gas appliances, as it explains what they must do if negative pressure or carbon monoxide is found in a building.
Home owners and residents may also watch this video to find out why their gas heating appliances should be serviced and tested every two years.
