Gas Leaks: What Every Perth Business Needs to Know

When it comes to gas leaks in commercial and industrial environments, there’s zero room for error. From office buildings and shopping centres to warehouses and high-rise facilities, gas-related incidents can jeopardise staff safety, interrupt business operations, and result in costly downtime and property damage.

At Majestic Plumbing, our licensed gas fitters understand the urgency and complexity of commercial gas leaks—early detection and prompt action is critical.

What Causes a Commercial Gas Leak?

Gas leaks in commercial settings can result from:

Ageing or damaged gas appliances
Improper installation or maintenance of commercial gas systems
Accidental damage during construction or groundworks
Faulty regulators, valves or fittings under high demand

Regardless of the cause, even minor leaks in a commercial environment can escalate quickly, risking fire, explosion, or toxic exposure.

Common Signs of a Gas Leak

Be alert for these warning signs on your site:

Strong sulphur smell: Often described as a “rotten egg” odour.
Unexplained vegetation die-off: Could indicate a buried leak near landscaping or outdoor pipework.
Audible hissing: High-pressure systems may produce noticeable sounds if compromised.
Physical symptoms among staff: Dizziness, headaches, or nausea could point to poor air quality caused by gas.
Visible disturbances: Dust blowing or bubbling from the ground near underground mains.

If any of these signs are present, immediate action is essential.

What to Do If You Smell Gas Inside Your Facility

Evacuate the Area: Immediately clear staff and visitors from the premises. Open windows and doors if safe to do so.
Avoid Ignition Sources: Do not operate machinery, flick light switches, or use mobile phones. Any spark could ignite the gas.
Shut Down the Gas Supply: If trained and it’s safe, turn off your main gas supply or LPG system.
Contact a Licensed Gas Plumber: Call Majestic Plumbing’s emergency team. We have the experience and technology to detect and resolve commercial gas leaks safely.

What to Do If You Smell Gas Outside

Clear the Area: Remove staff and vehicles from the vicinity. Do not operate any equipment.
Eliminate Ignition Sources: Cease all hot works, smoking, and power tool use near the leak.
Notify ATCO or Emergency Services: If the leak affects public infrastructure or is near a gas main, call ATCO Gas Emergency Line at 13 13 52.
Call Majestic Plumbing: For private property or within commercial premises, we’ll identify the source, isolate the problem, and repair it with minimal disruption to your operations.

Faulty Gas Appliances in Commercial Buildings

Commercial kitchens, Hot Water Systems, and Gas-powered equipment must be regularly serviced to avoid incidents. 

Warning signs include:

If you spot these, stop using the appliance and contact us for inspection and servicing.
