Natural gas leaks in commercial and industrial premises require a safety-first response. A smell resembling rotten eggs, a hissing sound, failed appliance ignition, repeated appliance lockouts, pressure loss, abnormal gas bills, a supplier warning or a failed pressure test can each warrant investigation. In larger premises, the source may not be immediately visible because pipework can run through ceiling spaces, service ducts, risers, plant rooms, roof areas and external meter locations.
If gas can be smelt, treat the matter as urgent. Avoid ignition sources and do not operate electrical switches or appliances. Move away from the affected area and contact ATCO, the gas supplier or an appropriately licensed gasfitter. Do not try to locate, tighten, repair, test or re-light a commercial gas system yourself.
Where natural gas leaks can occur
Natural gas leak work concerns suspected leaks across gas pipework and connected equipment. Depending on the premises, this can involve meters, regulators, valves, appliance connections, boilers, hot water plant, commercial kitchen equipment and other gas-fired systems.
Restaurants, hotels, clubs, schools, hospitals, aged care facilities, apartment buildings, laundries, workshops and plant rooms can each have different access arrangements and operational constraints. A gasfitter may also need to work around meter enclosures, risers, roof plant areas or external service compounds.
The fact that a smell or fault is noticed in one place does not establish the source. Investigation may consider the supply, meter, regulator, pipework, appliance connection, valve, control, burner train or appliance itself.
What commercial natural gas leak detection can involve
Commercial natural gas leak detection starts with the reported symptoms, the asset involved and the site conditions. A gasfitter may isolate sections of an installation, carry out gas pressure testing, inspect accessible connections and check relevant regulators before determining the appropriate repair scope.
Emergency isolation and make-safe works
Gas pressure testing and leak tracing on exposed or concealed pipework
Checks of regulators, valves, unions and appliance connections
Commercial kitchen gas rail and appliance connection testing
Leak investigation for boilers, water heaters and plant-room equipment
Assessment of safe operation before gas is restored following repair
Where a commercial gas leak repair is required, the work may involve repairing or replacing failed fittings, valves or pipework. The scope depends on the asset, symptoms, isolation points, access and consequence of failure; it may be a service call, a planned repair or a larger item requiring further coordination.
Managing disruption at a business or facility
Gas work at a commercial site may need to fit around tenants, trading activity, plant access and shutdown restrictions. In some circumstances, staged shutdowns, tenant notification, access permits, after-hours attendance or coordination with the gas network operator may be needed.
For emergency commercial gas leak repair, let the plumbing business know who can authorise urgent work and whether the affected area is occupied. Facility managers, strata managers, business owners, maintenance coordinators and asset managers can help make the first discussion more productive by identifying the relevant asset and access arrangements.
Information to have ready
Clear site information helps a gasfitter understand the reported issue and plan access. Provide what is safely available; do not place yourself at risk to collect details or images.
Give the site address, contact person and access instructions.
Describe where the smell, sound or fault was first noticed and whether any gas appliances are still operating.
Identify the gas meter location, gas type and affected appliance or plant where known.
Share appliance make, model and serial details, along with photos of labels, meters, regulators, visible pipework or damaged areas where safe.
Advise whether ATCO or the gas supplier has attended and whether a warning notice has been issued.
Outline shutdown restrictions, induction requirements, permits, permitted working hours and the person authorised to approve repairs.
Asset IDs, drawings, manuals, past service reports and maintenance history can also assist where the affected equipment forms part of a larger facility system.
Gas leak testing and repair in commercial settings
Commercial gas leak testing may involve checking the installation after sections have been isolated and examining connections or equipment associated with the reported fault. Following repair, recommissioning and safe-operation testing may be needed before gas is restored.
Because the condition of pipework and equipment cannot be determined from symptoms alone, avoid assuming that a failed appliance, a pressure issue or an odour identifies a particular component. The investigation should establish the relevant source and the repair required.
Gas products and equipment customers may encounter
Commercial sites can contain equipment and components from a wide range of manufacturers and supply channels. Examples customers may encounter include Kleenheat Gas and Origin in connection with gas supply, Rinnai, Rheem, Bosch, Vulcan and Dux for gas-fired water-heating equipment, and Bromic, Hobart, Cookon, Goldstien and Luus in commercial kitchen environments. Reece, Galvins and Tradelink are also names customers may see in relation to plumbing products and supply channels.
Product names and labels can be useful details when reporting a fault, particularly where an appliance, boiler, water heater, regulator or kitchen item is involved. Their presence does not by itself identify the cause of a suspected leak or the repair required.
Choose a plumbing business with clearer information
Gas fitting covers the supply, connection, testing and repair of natural gas and LPG systems and appliances. In commercial settings, gas work also needs to account for asset criticality, site access, safety and disruption to operations. Find a Master Plumber connects customers with Master Plumbers and plumbing businesses associated with the Master Plumbers and Gasfitters Association of Western Australia.
Find a Master Plumber is backed by the Association, which has represented Western Australia’s plumbing and gasfitting industry since 1901. Choosing a Master Plumber helps consumers make a more informed choice of plumbing business for their property or project.
Possible signs include a rotten egg smell, hissing, failed appliance ignition, repeated appliance lockouts, pressure loss, abnormal gas bills, a supplier warning or a failed pressure test. These signs do not establish the source of the issue.
What should we do if gas can be smelt at our premises?
Treat it as urgent: avoid ignition sources, do not operate electrical switches or appliances, move away from the affected area, and contact ATCO, the gas supplier or an appropriately licensed gasfitter. Do not attempt repairs or re-lighting.
Can the leak be inside concealed pipework?
It can be difficult to identify the location from symptoms alone. Commercial gas pipework may run through ceiling spaces, service ducts, risers, plant rooms, roof areas or external locations before reaching an appliance.
What details should we provide when reporting a suspected gas leak?
Provide the site address, symptoms and location, meter location, affected equipment details where known, supplier attendance or warning information, access requirements, shutdown restrictions and the urgent-work authoriser.
What can commercial gas leak testing involve?
It may involve isolation, pressure testing, leak tracing, inspection of connections and checks of relevant valves or regulators. The work required depends on the site, affected assets and reported symptoms.
Why might a site need coordination before gas work proceeds?
Commercial premises may have tenants, operational restrictions, permits, induction requirements, restricted access or shutdown windows. These details can affect how investigation and repair are arranged.
For natural gas installation work or faults not identified as a suspected leak, use the related commercial gas service pathways to choose a plumbing business that suits the work required.
