Electrical Safety During Storms: Before, During, and After

Severe storms -- whether thunderstorms, hurricanes, or winter ice storms -- create significant electrical hazards. Lightning, downed power lines, flooding, and power outages all present risks that homeowners need to understand and prepare for. This guide covers essential electrical safety measures for before, during, and after severe weather events.

Before the Storm: Preparation

Surge Protection

Lightning strikes and power grid disturbances during storms cause damaging power surges. Before storm season:

• Install whole-home surge protection at your electrical panel
• Use point-of-use surge protectors for sensitive electronics
• Consider surge protection for cable, phone, and internet lines

Backup Power Planning

Extended outages are common during severe storms. Consider your options:

• Portable generators: Affordable but require careful, safe operation
• Standby generators: Automatically activate during outages - ideal for homes with medical equipment needs or frequent outages
• Battery backup systems: Silent, indoor operation with no fuel requirements

Emergency Kit Preparation

Assemble electrical-related emergency supplies:

• Flashlights with fresh batteries (avoid candles - fire risk)
• Battery-powered or hand-crank radio
• Portable phone chargers (fully charged)
• Extra batteries in various sizes

During the Storm: Immediate Safety

Lightning Safety

When thunderstorms approach:

• Stay away from electrical equipment and appliances
• Avoid contact with plumbing - pipes can conduct lightning strikes
• Unplug sensitive electronics before the storm arrives (if safe to do so)
• Avoid corded phones - use cell phones instead
• Stay away from windows and doors, especially those with metal frames

If Power Goes Out

• Turn off and unplug major appliances to prevent surge damage when power returns
• Leave one light on so you know when power is restored
• Keep refrigerator and freezer doors closed
• Use flashlights, not candles
• If using a generator, never operate it indoors or in an enclosed space

Flooding Concerns

Water and electricity are a deadly combination:

• If flooding threatens your electrical panel or outlets, turn off the main breaker if you can do so safely without standing in water
• Never touch electrical equipment while standing in water
• If you could not shut off power before flooding, call the utility company to disconnect
• Evacuate if your electrical system is flooded

After the Storm: Recovery Safety

Downed Power Lines

Downed power lines are extremely dangerous:

• Assume ALL downed lines are energized - even if they are not sparking
• Stay at least 35 feet away from downed lines
• If a line is across your car, stay inside unless the vehicle is on fire
• Report downed lines to your utility company immediately
• Keep others away and warn approaching pedestrians or drivers

Before Restoring Power

Do not just flip the main breaker back on. First:

• Check for standing water near the electrical panel
• Look for visible damage to wiring, outlets, or the panel itself
• Smell for burning odors
• Check outside for damage to the meter base or service entrance

If you notice any damage or flooding, have an electrician inspect before restoring power.

Flood-Damaged Electrical Systems

If any part of your electrical system was submerged:

• Do not restore power until a licensed electrician inspects the system
• Submerged outlets, switches, and wiring may need replacement
• The electrical panel may require complete replacement
• Appliances that were submerged should not be used until inspected
• Document all damage for insurance purposes

Generator Safety After Storms

If using a portable generator during extended outages:

• Never run generators indoors, in garages, or in enclosed spaces - carbon monoxide is deadly
• Place generators at least 20 feet from the home with exhaust pointing away
• Never connect generators directly to home wiring without a transfer switch
• Let generators cool before refueling
• Use heavy-duty, outdoor-rated extension cords

When to Call an Electrician

Contact a licensed electrician after a storm if:

• Your electrical system was flooded or exposed to significant moisture
• You see visible damage to wiring, outlets, or your panel
• You smell burning or notice scorch marks
• Breakers trip immediately when you try to restore power
• Your home was struck by lightning
• You notice flickering, buzzing, or other unusual behavior after power is restored

Long-Term Storm Preparedness

Consider these improvements for better storm resilience:

• Whole-home surge protection: Essential for lightning-prone areas
• Standby generator: Automatic backup power for critical needs
• Panel upgrade: Modern panels with better protection features
• Smart home monitoring: Alerts you to power issues even when away
