Severe weather, including thunderstorms, hurricanes, and lightning strikes, can wreak havoc on your home’s electrical system. Storms bring a heightened risk of power surges, outages, electrical fires, and personal injury due to electrical hazards. Knowing how to prepare for these risks and respond when severe weather strikes is crucial for keeping your home and family safe.

In this post, we'll cover essential storm electrical safety tips, including how to safeguard your electrical system before a storm, what to do during a storm to avoid hazards, and how a licensed electrician can help you prepare for future severe weather events.

Preparing for a Storm: Safeguarding Your Electrical System

Before a storm hits, it's important to take steps to protect your home’s electrical system. A few simple precautions can minimize damage and reduce the risk of electrical fires or shock.

1. Install Whole-House Surge Protection

One of the most effective ways to protect your home from power surges caused by lightning or other storm-related incidents is by installing whole-house surge protection. Surge protectors are designed to divert excess electrical current away from your home’s wiring, preventing sensitive electronics and appliances from being damaged.

Surge protection devices can be installed directly in your home’s electrical panel by a licensed electrician. This will protect all the devices and appliances in your home, including HVAC systems, refrigerators, computers, and televisions.

For additional protection, use plug-in surge protectors for valuable electronics like laptops and gaming systems. These devices will add an extra layer of defense against surges that could occur during a storm.

2. Unplug Appliances and Electronics

Before a storm arrives, it’s a good idea to unplug non-essential appliances and electronics. This step reduces the risk of damage from sudden power surges caused by lightning strikes or power outages. Major appliances, such as refrigerators and HVAC systems, may remain plugged in if you haven’t installed whole-house surge protection, but sensitive electronics like TVs, computers, and audio systems should be disconnected from the electrical grid.

3. Keep Generators Ready for Use

For homes prone to power outages, having a backup generator is crucial. Make sure your generator is ready for use before a storm hits by ensuring it’s properly fueled, maintained, and tested. It’s also important to use your generator safely:

• Place portable generators outside, away from windows and doors, to avoid carbon monoxide buildup.

• Never connect your generator directly to your home’s wiring unless a licensed electrician has installed a transfer switch.

• Use extension cords rated for heavy-duty use and ensure they are in good condition.

If you don’t already have a generator or transfer switch installed, consider calling a licensed electrician to prepare your home for future outages. An electrician can help you choose the right generator size and ensure the installation meets local safety codes.

During a Storm: Staying Safe Indoors and Out

Once the storm hits, your primary goal should be to stay safe and minimize electrical hazards inside and outside your home. Here are some fundamental safety tips to follow during a storm.

1. Stay Inside and Away from Electrical Devices

During a storm, it’s best to avoid using electrical appliances and devices. Lightning strikes can cause power surges that travel through your home’s electrical system, putting you at risk of electric shock if you’re using an appliance when a strike occurs.

In addition, avoid touching electrical outlets, light switches, and anything connected to your home’s wiring, such as televisions and phones connected by landlines. If you need to use your cell phone, use it wirelessly rather than plugged in to charge.

2. Be Aware of Water and Electricity

Flooding is a common result of heavy storms, and water combined with electricity is a dangerous mix. If your home begins to flood, stay clear of any electrical outlets, appliances, or devices. Water can easily carry electricity, creating a life-threatening hazard.

If you notice water around electrical components, do not attempt to touch or unplug anything. Instead, turn off primary power to your home using the main breaker—only if it is safe to do so. In extreme cases where there is a risk of electrocution or fire, evacuate the home and contact emergency services.

3. Stay Away from Downed Power Lines

Downed power lines are a significant hazard during and after storms. If you encounter a downed line, assume it is live and dangerous. Stay at least 30 feet away from it and anything it may be touching, including puddles of water or metal fences. Contact your local utility company immediately to report the hazard, and keep pets and children away from the area.

If a power line falls on your car while you are inside, stay in your automobile and wait for emergency services to arrive. Do not attempt to exit, as touching the ground while in contact with the vehicle could cause severe injury or death.

After the Storm: Inspecting for Damage and Hazards

Once the storm has passed, it’s time to assess your home for any electrical damage. This is also an excellent opportunity to call in an electrician to check for any potential hazards.

1. Check for Power Outages and Electrical Damage

If your power went out during the storm, turn off the main breaker and wait until local authorities confirm it is safe to restore it. Once the power is back on, inspect your home for any signs of electrical damage, such as flickering lights, tripped breakers, or damaged appliances.

If you notice any of these issues, contact a licensed electrician immediately. Do not attempt to repair electrical components on your own, as this can be dangerous and may lead to further damage.

2. Have Your Electrical System Inspected

After a significant storm, it’s always a good idea to have a professional electrician inspect your electrical system for potential issues. An electrician will check for damaged wiring, overloaded circuits, and water exposure in electrical components, ensuring that your home is safe to use after the storm.

If you’ve experienced multiple power outages or surges during the storm, an electrician can also recommend preventive measures, such as installing a surge protection device or upgrading your electrical panel.

3. Replace Damaged Outlets and Wiring

If your home sustained water damage during the storm, it’s crucial to replace any outlets, wiring, or electrical panels that were exposed to moisture. Water can corrode electrical components, increasing the risk of fire or electric shock. A licensed electrician can assess the damage and make necessary replacements to restore your home’s safety.

Stay Safe with Storm Electrical Precautions

Storms bring with them a host of electrical risks, from power surges to downed power lines. By taking precautions before the storm hits—such as installing surge protection and unplugging sensitive electronics—and following safety protocols during the storm, you can protect your home and loved ones from electrical hazards. After the storm, always inspect your home for damage and schedule an inspection with a licensed electrician to ensure everything is safe and functioning properly.
