Every May, the Electrical Safety Foundation International (ESFI) leads a nationwide campaign called National Electrical Safety Month. The goal is straightforward: use a dedicated, structured period to reduce the electrically related fires, deaths, injuries, and property losses that occur at a preventable rate throughout the year. The numbers make the case for why this attention is warranted. Home electrical fires account for an estimated 51,000 incidents each year in the United States, resulting in nearly 500 deaths, more than 1,400 injuries, and $1.3 billion in property damage annually. Arcing faults alone, a condition where electricity jumps across damaged or deteriorated wiring, are responsible for more than 28,000 of those fires. The U.S. Consumer Product Safety Commission reports that electrical receptacles are involved in approximately 5,300 home fires every year. And 65 percent of home fire deaths occur in homes without working smoke detectors. These are not random outcomes. They are the predictable result of electrical systems that have not been inspected, maintained, or upgraded to meet current safety standards. National Electrical Safety Month exists to interrupt that pattern with awareness, action, and the professional expertise to find and fix problems before they cause harm. Here is your complete plan for using May productively. Why May Is the Right Time to Act The timing of National Electrical Safety Month is deliberate. May marks the transition from winter heating loads to summer cooling loads, a period when electrical systems experience the shift from their highest-demand season to the next highest-demand season. It is also the start of outdoor activity, pool openings, landscaping projects, and patio entertaining, all of which introduce new electrical hazards. Spring is traditionally when homeowners do their most thorough maintenance review of the year. Electrical safety fits naturally into this schedule. May is also when the weather cooperates for attic and crawlspace inspection, when HVAC contractors are servicing cooling systems before the peak season, and when people are generally home and attentive rather than occupied with the holiday period. Use this month as a prompt for the electrical safety review that every home should complete at least annually. The electrical safety checklist is a room-by-room guide to what that review should cover. Your 10-Point May Electrical Safety Checklist 1. Schedule a Professional Electrical Inspection The single most effective action you can take during National Electrical Safety Month is booking a professional electrical inspection. A licensed electrician has the tools, training, and code knowledge to identify conditions that homeowners cannot detect through visual inspection alone. A professional inspection covers: Voltage stability and load balance across circuits Condition of wiring accessible in attic, basement, and crawlspace Status of the electrical panel: breaker function, internal connections, capacity GFCI and AFCI protection in all required locations Grounding and bonding continuity Condition of outlets, switches, and junction boxes throughout the home Smoke and CO detector placement and power source Homes over 25 years old should be inspected every three to five years. Homes over 40 years old with original wiring should be inspected annually. If your home has never had a professional electrical inspection, May is the month to schedule it. 2. Test Every GFCI Outlet in Your Home Ground fault circuit interrupters are among the most important shock-prevention devices in your home. They detect current leaking to ground and cut power within milliseconds, a protection that standard outlets cannot provide. Code requires GFCI protection in all bathrooms, kitchens, garages, basements, outdoor areas, and any other wet or damp location. Testing takes less than a minute per outlet: Press the TEST button on the GFCI outlet or on the GFCI circuit breaker that covers the circuit The button should pop out and power to the outlet should cut off, verify with a lamp or tester Press RESET to restore power If the outlet does not trip or does not reset, it needs professional replacement Test every GFCI outlet in your home this month. If GFCI tripping becomes erratic or frequent on a circuit, that symptom warrants investigation rather than repeated resetting. Professional GFCI installation is straightforward and among the highest-value safety upgrades available. 3. Know Your Electrical Panel Your main electrical panel is the hub of your home's power distribution. During National Electrical Safety Month, spend five minutes familiarizing yourself with it: Locate the panel and confirm it is accessible. Nothing should be stored in front of it Confirm the main breaker at the top is functional and accessible Check that individual breakers are labeled. If your panel is unlabeled or has labels you cannot read, updating the circuit map is a useful project Look for any breakers that are in an intermediate or tripped position without a known cause Note the panel brand. If it is Federal Pacific Electric (Stab-Lok) or Zinsco, schedule a professional evaluation. These panel types have documented failure modes where breakers do not trip under overload, creating serious fire risk If breakers trip frequently under normal loads, that is your panel communicating that something needs attention. Repeated resets without diagnosis are not a solution. If your panel is 25 or more years old, or if it is a fuse box rather than a circuit breaker panel, a panel upgrade consultation is worth scheduling during this month. 4. Test Smoke Detectors and CO Detectors Sixty-five percent of home fire deaths occur in homes without working smoke alarms. May is an ideal time to test every detector, confirm battery status, and verify that units are not past their replacement date. What to check: Test monthly by pressing the test button; if it does not sound, replace the battery first and retest. Replace the unit if it still fails Check the manufacture date on the back. Smoke detectors should be replaced every 10 years from the manufacture date, not the install date. CO detectors should be replaced every 5 to 7 years Verify placement, smoke detectors are required inside every bedroom, outside each sleeping area, and on every level including the basement. CO detectors are required on every level and outside sleeping areas Confirm battery backup; hardwired detectors should have a functioning battery backup in case of power outage The detector types guide covers detector types, sensor technologies, and placement requirements in detail. Professional smoke detector installation is the right call for homes that need hardwired or interconnected systems. 5. Audit Every Extension Cord Extension cords are involved in approximately 3,300 home fires each year. They are designed for temporary use, not permanent installation. During your May audit: Inspect every cord for damage, fraying, cracking, exposed conductors, or scorch marks at either plug end are grounds for immediate replacement. Never tape a damaged cord Check for cords under rugs or furniture; heat cannot escape from a covered cord. This is a fire hazard regardless of how the cord looks Identify any cords that have become permanent fixtures. A cord that has powered the same device in the same spot for months is standing in for a proper outlet. Add outlets where the load actually exists Confirm no major appliances are on extension cords; refrigerators, stoves, dryers, washing machines, and air conditioners must plug directly into wall outlets The extension cord safety guide covers cord ratings, safe use, and the specific scenarios that create fire risk. If your audit reveals chronic cord dependence in certain rooms, that is a signal to have dedicated circuits or additional outlets professionally installed. 6. Inspect All Visible Wiring and Cords Walk through your home systematically and look at every cord and cable you can see: Appliance cords: look at where cords enter and exit the appliance housing, where they are closest to heat sources, and at the plug end Lamp cords: these are often the oldest cords in a home and most subject to heat stress from proximity to bulbs Behind appliances: the back of a refrigerator, behind a dryer, under a dishwasher, these areas see heat, vibration, and repeated mechanical stress on wiring Computer and entertainment wiring: cord tangles and bundles trap heat and are frequently pinched by furniture legs Replace any cord showing deterioration. Do not attempt to repair damaged cords with electrical tape. Sparking outlets or scorch marks around outlet slots are warning signs that the outlet itself has sustained damage and needs professional replacement. 7. Assess Your Surge Protection Coverage Whole-home surge protection installed at the electrical panel is the most effective and comprehensive surge defense available. It protects every circuit and every connected device automatically, without requiring individual surge strips at each outlet. During your May review: If you do not have whole-home surge protection, this month is the time to schedule installation If you have point-of-use surge protectors, check that their indicator lights show they are functional. Surge protectors can absorb a surge and continue to function as a power strip while providing no surge protection, a misleading but common failure state Confirm that sensitive electronics, including computers, televisions, and smart home devices, are behind a surge protector Unplug major electronics during thunderstorms as a backup measure Whole home surge protection pairs with AFCI circuit breakers to address the two most common causes of electrical fires: external voltage spikes and internal arcing faults. 8. Evaluate Your Lithium-Ion Battery Habits ESFI's 2024 and 2025 National Electrical Safety Month campaigns focused specifically on lithium-ion battery safety, reflecting a growing hazard as these batteries power more devices than ever. Phones, laptops, tablets, e-bikes, e-scooters, power tools, and even toothbrushes now rely on lithium-ion batteries, each carrying a small but real risk of thermal runaway, fire, or explosion when damaged, improperly charged, or incorrectly disposed of. Safe lithium-ion battery practices: Purchase only certified products, look for UL, ETL, or CSA certification marks. Uncertified batteries and chargers are a primary cause of lithium-ion fires Use the charger that came with the device; third-party chargers that are not manufacturer-approved can deliver incorrect voltage or current, stressing the battery Charge on hard, flat surfaces, never charge on beds, couches, or upholstered furniture, which can trap heat and limit the battery's ability to cool Do not overcharge; unplug devices when they reach full charge. Leaving devices plugged in continuously creates ongoing thermal stress on the battery Inspect batteries for damage; a swollen, cracked, or leaking battery should be removed from use immediately and recycled; do not charge it Recycle properly; lithium-ion batteries should never go in regular trash or recycling bins. Find a certified drop-off location at call2recycle.org For e-bikes, e-scooters, and other high-capacity lithium devices, charge outdoors when possible and never charge in a room where you sleep. If a lithium-ion device emits smoke, a burning smell, or unusual heat during charging, move it away from combustibles, stop charging, and contact the manufacturer. 9. Evaluate Outdoor Electrical Safety Summer adds new electrical hazards: outdoor outlets, extension cords in the yard, pool and hot tub wiring, and equipment used near water. Before the season begins: Test all outdoor GFCI outlets using the test/reset process described above. All outdoor outlets must be GFCI-protected under current code Confirm weatherproof covers are intact on all outdoor outlets. In-use covers that protect plugged-in cords from rain are required on outlets where cords are regularly connected Never use indoor extension cords outdoors; they lack the moisture-resistant jacket required for outdoor use. Use cords with "W" in their type designation (SJTW, SOOW, etc.) Pool and hot tub wiring must be inspected and maintained by a licensed electrician. Any electrical work near water requires specialized knowledge of bonding, grounding, and GFCI requirements. Do not DIY pool or spa electrical Stay at least 10 feet from overhead power lines when using ladders, operating power equipment, or trimming trees Electrical hazards near water, whether from outdoor outlets, power tools, or pool wiring, are among the most rapidly lethal conditions in residential settings. 10. Have a Family Electrical Safety Conversation National Electrical Safety Month is a natural moment to bring your household together around a few basic principles, particularly if children are in the home. Topics to cover: Where the main electrical panel is and how to turn off a circuit breaker What to do if an outlet smokes, sparks, or smells like burning (stop using it, turn off the circuit, call an electrician) Why extension cords are temporary, not permanent solutions What the smoke detector and CO detector sounds mean and what to do when they go off The water-and-electricity rule: never use electrical devices near water, and dry hands before touching anything plugged in For households with young children, tamper-resistant outlets on all accessible outlets are a baseline protection. These are now required in new residential construction and are inexpensive to retrofit. The childproofing electrical guide covers the full set of child-specific electrical safety measures. Warning Signs That Demand Attention Before Summer National Electrical Safety Month is also the right time to address any symptoms your home's electrical system has been producing. Do not carry these into the high-demand summer season: Lights that flicker or dim when appliances start, the flickering lights guide walks through what each pattern indicates, and when professional evaluation is required Outlets or switch plates that are warm or hot to the touch, heat at a cover plate means heat is building inside the wall at a connection point. This is a fire precursor, not a nuisance A burning smell with no identifiable source, an electrical fire emits an acrid, plastic-like, or metallic odor. Turn off the circuit and call an electrician Outlets that are dead, discolored, or show scorch marks, these indicate that overheating has already occurred Circuit breakers that trip repeatedly under loads that have not changed Aluminum wiring, knob and tube wiring, or a fuse box, all conditions identified in the older home electrical guide that need professional assessment before additional load is placed on the system Addressing these issues in May, before the summer cooling season pushes electrical loads higher, is the practical approach.
