Energy Safe Victoria

The Victorian Type B Gasfitting licence is an advanced gasfitting class for complex gas work on Type B appliances — gas-fired plant with an input above 10 MJ/h such as commercial and industrial boilers, furnaces, kilns and process heaters. Registration is administered through the Victorian Building Authority / Building and Plumbing Commission and requires a minimum of two years' Provisional Registration plus an open-book registration assessment in which relevant reference materials (AS/NZS 5601.1, AS 3814 and AS 2593) are permitted. Type B appliances are governed by AS 3814 for the appliance and AS/NZS 5601.1 for the installation, and gas must not be connected until Energy Safe Victoria grants acceptance under its gas acceptance scheme (Schedule 9, lodged via GasTrac). Content spans Type B appliances and safety systems, combustion, flueing and ventilation, testing, purging and commissioning, gas pressures and regulation, gas properties, and Victorian gas safety legislation. This free prep includes 100 research-based practice questions with explanations and an AI tutor.

Sample Type B Gasfitting (VIC) Practice Questions

Try these sample questions to review concepts for the Type B Gasfitting (VIC) exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Under the Victorian framework, a gas appliance is classified as Type B when its gas consumption exceeds which energy input, provided it is not a Type A appliance?
A.1 MJ/h
B.10 MJ/h
C.500 MJ/h
D.5000 MJ/h
Explanation: A Type B appliance is one with a gas consumption in excess of 10 MJ/h that is not a Type A appliance. Type A appliances are those covered by an authorised acceptance scheme (typically domestic and light-commercial units up to about 1000 MJ/h), so anything outside that scheme above 10 MJ/h is Type B.
2Which Australian Standard sets out the requirements for the design, construction and safe operation of industrial and commercial (Type B) gas-fired appliances?
A.AS/NZS 5601.1
B.AS 3814
C.AS 4575
D.AS/NZS 5601.2
Explanation: AS 3814 'Industrial and commercial gas-fired appliances' specifies the minimum requirements for the design, construction and safe operation of Type B appliances. A Type B appliance must be assessed against AS 3814 before gas can be supplied to it.
3Which standard governs the installation (consumer piping, connection and commissioning of the installation) of a Type B appliance in Victoria?
A.AS 3814
B.AS/NZS 5601.1
C.AS 2593
D.AS 4625
Explanation: While AS 3814 covers the appliance itself, the gas installation that supplies a Type B appliance — consumer piping, regulators, isolation and connection — is installed in accordance with AS/NZS 5601.1 Gas installations Part 1: General installations.
4Before gas may be connected to a new Type B appliance in Victoria, what must be obtained from Energy Safe Victoria?
A.A certificate of compliance only
B.Acceptance under the gas acceptance scheme
C.A building permit
D.An electrical safety certificate
Explanation: An Application for Acceptance must be submitted to Energy Safe Victoria and acceptance granted before gas is connected to a complex gas installation or a Type B appliance. This is the gas acceptance scheme, and applications are lodged through GasTrac.
5Which document accompanies an Application for Acceptance for a new, modified or relocated Type B appliance, providing the additional technical information Energy Safe Victoria requires?
A.Schedule 6
B.Schedule 9
C.A Form 1 occupancy permit
D.An EICR
Explanation: A Schedule 9 must accompany the Application for Acceptance for a new, modified or relocated Type B appliance. It captures the additional technical information (appliance data, combustion, flue and safety system details) that Energy Safe Victoria assesses before granting acceptance.
6In Australia, the nominal supply (test point) pressure for natural gas at a domestic/commercial appliance is approximately:
A.1.13 kPa
B.2.75 kPa
C.10 kPa
D.70 kPa
Explanation: The standard nominal natural gas supply pressure at the appliance test point in Australia is 1.13 kPa. By comparison, LP Gas is supplied at a nominal 2.75 kPa, which is why appliances must be matched and adjusted to the gas type and pressure available.
7The nominal supply (test point) pressure for LP Gas at an appliance in Australia is approximately:
A.1.13 kPa
B.2.75 kPa
C.5.0 kPa
D.1.0 kPa
Explanation: LP Gas is supplied at a nominal 2.75 kPa at the appliance, compared with 1.13 kPa for natural gas. The higher pressure reflects LPG's different combustion characteristics and higher calorific value.
8Natural gas (predominantly methane) has a specific gravity relative to air of approximately:
A.0.6 (lighter than air)
B.1.0 (same as air)
C.1.5 (heavier than air)
D.2.0 (heavier than air)
Explanation: Natural gas has a specific gravity of about 0.6, so it is lighter than air and will rise and disperse upward if released. This influences leak detection and the placement of ventilation and gas alarms compared with LP Gas.
9LP Gas (propane) has a specific gravity relative to air of approximately 1.5. The most important safety implication of this is that LP Gas:
A.Rises and collects at ceiling level
B.Sinks and collects at low points and floor level
C.Has the same density as air and disperses evenly
D.Cannot accumulate in enclosed spaces
Explanation: Because propane is about 1.5 times the density of air, leaked LP Gas sinks and pools at low points such as floors, pits, drains and trenches. Low-level ventilation and low-level gas detection are therefore critical in LPG installations.
10The flammability (explosive) range of natural gas in air is approximately:
A.5% to 15%
B.2% to 10%
C.0.5% to 4%
D.20% to 40%
Explanation: Natural gas (methane) has a flammable range of roughly 5% to 15% by volume in air, between its lower and upper explosive limits. Mixtures below 5% are too lean and above 15% are too rich to ignite.

About the Type B Gasfitting (VIC) Exam

The Victorian Type B Gasfitting licence authorises advanced, complex gas installation work on Type B appliances — large commercial and industrial gas appliances with a gas input above 10 MJ/h, such as boilers, furnaces, kilns and process heaters. Candidates must hold Provisional Registration for at least two years and pass an open-book registration assessment built on AS/NZS 5601.1, AS 3814 and AS 2593, and work on Type B appliances requires acceptance from Energy Safe Victoria before gas is connected.

Exam sponsor: Victorian Building Authority (VBA) / Building and Plumbing Commission, with Energy Safe Victoria as gas safety regulator. The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Frequently Asked Questions

What is a Type B gas appliance in Victoria?

A Type B appliance is a gas appliance with a gas consumption above 10 MJ/h that is not a Type A appliance (Type A units are covered by an authorised acceptance scheme). Type B appliances are large commercial and industrial gas-fired plant such as boilers, furnaces, kilns and process heaters.

What standards apply to Type B gasfitting work?

The appliance itself is assessed against AS 3814 (industrial and commercial gas-fired appliances), and the gas installation supplying it is installed under AS/NZS 5601.1. AS 2593 applies to boiler safety management. AS/NZS 5601.1 and 5601.2 are prescribed under the Gas Safety (Gas Installation) Regulations 2018.

Do I need Energy Safe Victoria acceptance before connecting gas to a Type B appliance?

Yes. An Application for Acceptance (with a Schedule 9 for new, modified or relocated Type B appliances) must be lodged through GasTrac and acceptance granted by Energy Safe Victoria before gas is connected. Type B appliance applications are typically processed within about 10 working days.

What are the eligibility requirements for the Type B Gasfitting class?

Applicants must hold Provisional Registration for a minimum of two years (initially 12 months, then renewed for a further 12 months) and demonstrate competency in complex gas work, then complete the relevant Building and Plumbing Commission registration assessment.

Is the Type B Gasfitting registration exam open book?

Yes. Candidates are permitted to bring relevant reference materials, including AS/NZS 5601.1, AS 3814 and AS 2593, so fast and accurate navigation of the standards is as important as underlying knowledge. The registration process also includes a practical assessment.
