Why homeowners are facing rise in electrical fires as winter begins — here’s how to stay safe

An electrical fire is one of the most serious and silent dangers in the home. 

Without warning, homeowners can quickly find themselves facing a blaze started by appliances and within the walls without even realizing there’s a problem. 

While a risk year-round, the danger spikes during winter, with 30% of all home fires involving electrical failure or malfunction happening from November to February, according to the National Fire Protection Association.

Experts agree that while homeowners should be cautious all year, there are specific measures they should take to be extra careful during the colder months. 

Why are electrical fires more common in winter?

Bob Marshall, electrical engineer and CEO of Whisker Labs, a maker of AI-driven electrical hazard detection systems, explains that the colder months typically coincide with increased use of the home.

“From space heaters to slow cookers, there are hidden electrical fire hazards in places that might seem harmless,” he explained. “Without proper use and attention, these devices can become dangerous.”

Most especially, as the temperature drops, homeowners are putting the home’s electrical system to its limit with items like space heaters and electric blankets.

Another issue? Improper use of extension cords. Many people use light-duty indoor cords for high-wattage heaters, causing the cord itself to potentially overheat, melt, and ignite.

What are the warning signs of an electrical fire?

The first line of defense is if something seems odd to you, say something, even if it seems minor. 

“Flickering lights are one of the most common and visible signs that something may be wrong with your home’s electrical system,” notes Marshall. “They’re often caused by a loose connection, either in your home’s wiring or the utility equipment outside. Loose connections can cause electrical arcing, which produces heat and increases fire risk. If you notice frequent or consistent flickering, turn off the breaker to that circuit and schedule an inspection with a licensed electrician.”

Other indications that there’s an issue are sounds and smells that weren’t there before. 

“Electrical hazards often come with smells, sounds, or visual cues. If you notice an outlet or switch that is buzzing, discolored, giving off an odd smell, or feels hot to the touch, stop using it and contact an electrician right away.”

How to prevent electrical fires before they happen 

The most important way to proactively protect your home from electrical fires is to use your appliances wisely, especially as temperatures drop. 

This means avoid overloading outlets or power strips, both inside the house and outdoors. 

“Never plug space heaters into extension cords or power strips,” Marshall says, “and inspect holiday lights before using.”

When it comes to any electric heater or heating pad, choose safety-certified products, avoid folding or compressing them, and never leave them plugged in when not in use.

“It’s also a good idea to replace these types of devices every 10 years,” adds Marshall. “Space heaters in particular need extra caution. Plug them into an unused outlet on a low-traffic circuit, ideally one that isn’t also powering major appliances. Never use them with extension cords or leave them running overnight.”

But even if you’re diligent, hazards can still develop silently behind walls. 

Smart home sensors like Whisker Labs’ Ting device can help protect against the risks you can’t see. “Ting detects early warning signs and alerts you so you can take action before it turns into something serious,“ Marshall explains.

Speaking of warning signs, make sure smoke alarms and carbon monoxide detectors are working. They can act as yet another alert to the danger ahead. And keep a fire extinguisher on hand—even if you don’t think you’ll burn the turkey this year.
