Carbon monoxide safety program

Type A Appliance Gasfitter Toolkit

ESV has developed a Type A Appliance Gasfitters Toolkit to provide you with guidance on keeping safe, and information to assist you in keeping your clients’ gas heaters operating in a safe manner.

See ESV Gasfitter Toolkit.

Carbon Monoxide Spillage Testing

What to do if you detect carbon monoxide spillage

If you detect carbon monoxide spillage during the servicing of a Type A gas appliance, you must take steps to make the installation safe (the appliance must be fixed or isolated).

If you are unable to do so, you must notify Energy Safe Victoria on 1800 652 563 (select Option 5)

Further information is available on the ESV website .

What to do if there is no carbon monoxide spillage, but there is negative pressure

If you identify that the Type A gas appliance/s you are servicing are installed in a living space subject to negative pressure, you must provide your client with a copy of the letter from the VBA and Energy Safe Victoria (PDF, 149.47 KB) which provides further information about negative pressure, and actions that the owner or occupier of the premises can take, to rectify the negative pressure situation.

If you have any queries about the above, you can contact the VBA on 1300 815 127 during business hours.

Requirements for gas servicing work – mandating AS 4575 and lodgement of a gas servicing record

On 1 June 2022, amendments to the Gas Safety (Gas Installation) Regulations 2018 came into effect which mandated AS 4575 – Servicing Type A gas appliances as the prescribed standard for servicing work on Type A gas appliances. The amendment regulations also made it mandatory for gasfitters to create and lodge a record of this servicing work with the VBA.  Further information is provided on the AS 4575 webpage.

ESV instructional video

ESV has produced a short instructional video demonstrating the steps required to correctly test for negative pressure and carbon monoxide spillage . The video guides you through these important tests, outlining faults common to gas heaters and demonstrating how to identify and combat the effect of negative pressure.

It also provides information to be aware of when testing for carbon monoxide spillage. This includes safety tips for carrying out this important work.

You should refer to this video before servicing or testing open-flue gas appliances, as it explains what you must do if negative pressure or carbon monoxide is found in a building.

It may also be useful for owners or occupiers to watch this video to reinforce why their gas appliances should be serviced and tested every two years.

Weather sealing or draught proofing activities where flueless gas space heaters and open flued gas space heaters installed

Weather sealing or draught proofing activities to make homes more energy efficient (such as sealing of doors, windows, unsealed wall vents, evaporative cooler vents, chimneys, flues of open fireplaces and replacing/ modifying wall or ceiling exhaust fans) after flueless gas heaters or open flue gas heaters have been installed can result in reduced ventilation in the home. As a result, these activities can increase the risk of carbon monoxide poisoning.

As a gasfitter, you may be engaged to conduct a negative pressure and carbon monoxide test (for open flued gas space heaters) and that adequate ventilation is provided (for flueless space heaters) to ensure the home remains safe following weather sealing or draught proofing activities in a home with existing gas appliances.

Frequently asked questions

Who needs to complete the module?

The VBA has developed a gas safety learning module which is designed to ensure that all Victorian gasfitters stay up to date with current testing procedures.

If you have not been registered or licensed in any of the classes of gasfitting since 2018 and have not completed the module, you must complete the module before you can become re-registered or licensed. Your registration or licensing in gasfitting will not be renewed if you have not completed the module.

Why am I required to do the learning module?

The VBA takes consumer safety seriously. As a gasfitter, we’re sure you do too.

The learning module is designed to ensure that all Victorian gasfitters stay up to date with current testing procedures.

On your next renewal date (occurring on or after 1 November 2018):

  • Your ID card and "Find a Practitioner" record will no longer state that you are a qualified gasfitter.
  • You will not be able to lawfully complete any gasfitting work.

Additionally, if you are a licensed gasfitter:

  • You will not be able to supervise registered practitioners or apprentices in gasfitting work.
  • You will not be able to issue compliance certificates in this work.

I’m intending to retire and not renew my registration or licence when it expires. Do I still need to complete the module?

We recommend you complete the module, even if you intend to retire or leave the industry. You need to stay up to date with current testing procedures while you are working as a gasfitter.

I no longer reside or work in Victoria. Do I still need to the complete the module?

We recommend you complete the module to ensure you stay up to date with current testing procedures.

If you no longer want to retain your registration or licence in Victoria, please let us know by sending an email to plumbingreg@vba.vic.gov.au.

I’m a Type B Gasfitter. Do I have to complete the module?

You will need to complete the module if you are also registered or licensed in the main class of Gasfitting or the specialised classes of Type A Appliance Servicing or Conversion work.

I hold a restricted gasfitting registration. Do I need to complete the module?

Yes – if you want to renew your gasfitting registration when it is next due.

I attended the VBA's Carbon Monoxide Safety Program and/or completed carbon monoxide training with Master Plumbers. Do I need to complete the module?

Yes. If you do not complete the module, you will no longer be eligible to work as a gasfitter from the date of your next renewal.

Having attended the recent training run by the VBA and/or Master Plumbers will assist you in successfully completing the learning module.

How do I access and complete the module?

Please contact the VBA on 1300 815 127 and we will send you a link to the module.

You can complete the module on a smartphone, tablet or computer. You just need an internet connection. If you don’t have one of these devices, and you can access your email online, you can complete the module from any smartphone, tablet or computer (such as an office computer, a friend’s computer or a computer at a library).
