Summer Fire Safety: The Electrical Risks Most Perth Homes Miss
Summer in Perth brings long days, backyard BBQs, pool parties, and scorching heat — but it also brings a rise in electrical fire risks that often go unnoticed.
When temperatures climb and appliances work overtime, even small electrical issues can quickly become dangerous.
This guide breaks down the most common electrical fire hazards we see in Perth, how to identify them, and when to call a licensed electrician.
1. Overloaded Power Boards
Power boards are convenient — but in summer, they’re often pushed to their limits.
Why it’s dangerous:
Too many appliances = overheating
Cheap boards can melt or spark
Daisy-chaining power boards is a major fire risk
Warning signs:
Warm or hot power board
Discolouration
Buzzing, crackling, or a burning smell
Tripped circuits when multiple appliances run
Tip: Use a single, high-quality, surge-protected board — and avoid plugging in heat-producing appliances together (heaters, dryers, AC, irons).
2. Dusty or Blocked Air Conditioning Units
Aircons collect dust, leaves, and debris over winter. The first hot days of summer put huge pressure on a system that hasn’t been cleaned or serviced.
Why it’s dangerous:
Blocked airflow = overheating
Overheating compressors can spark
Electrical components fail under load
Warning signs:
AC struggling to cool
Burning smell
Outdoor unit unusually hot
Buzzing or humming from inside the unit
If you notice any of these, shut it down and get it checked.
3. Damaged or Aged Extension Cords
Extension cords are the #1 electrical fire hazard in Australian homes.
Summer = Christmas lights, pool equipment, garden tools, outdoor fridges — all commonly used with cords that aren’t meant for long-term or outdoor use.
Why it’s dangerous:
UV damage to insulation
Water exposure
Overheating from high load
Coiled cords trap heat
Warning signs:
Cracks or exposed internal wiring
Warm cord or plug
Flickering lights when in use
Electrical shocks or tingles
Always choose outdoor-rated cords and avoid running them under rugs, mats, or through doorways.
4. Outdoor Power Sockets Exposed to Heat or Moisture
Outdoor living is huge in WA — but weather-exposed power points often deteriorate quickly.
Why it’s dangerous:
Water + electricity = instant fire or shock risk
Plastic casings warp in heat
Insects get inside and cause shorts
Dust, sprinklers, and humidity accelerate wear
Warning signs:
Cracks or discolouration
Loose outlet covers
Flickering power when plugged in
Tripped RCDs when outlets get wet
Outdoor sockets should always be weatherproof and regularly checked.
5. Old or Overloaded Switchboards
Summer places massive demand on electrical systems — especially in older homes that weren’t built for modern loads.
Why it’s dangerous:
Circuits overheat
Fuses blow or melt
RCDs fail
Loose wiring expands in the heat
Warning signs:
Regular tripping
Burning smell near the switchboard
Flickering lights
Buzzing or heat from inside the panel
If your switchboard is older than 15–20 years, summer is the most common time it will fail.
