A practical power outage prep checklist for flashlights, chargers, appliances, food, medical needs, and generator safety.
How to test GFCI outlets in bathrooms, kitchens, garages, basements, laundry areas, and outdoor spaces.
How to test garage door photo eyes and the safety reversal system, plus when to stop using the opener.
Smoke alarms detect particles from fire. CO detectors detect carbon monoxide gas, which is invisible and odorless. They protect against different threats, have different placement rules, and have different replacement schedules. Most homes need both.
Place water leak sensors at the eight most common leak points first: water heater, washing machine, dishwasher, refrigerator water line, under every kitchen and bathroom sink, near the sump pump, and any toilet supply line.
Standby generators self-exercise weekly, but homeowners should verify operation monthly and have professional service yearly. Portable generators need monthly run-up (15 to 20 minutes under load) and fuel that hasn't sat over 3 months without stabilizer.
Test AFCI breakers and outlets monthly by pressing the test button. The device should trip immediately; press reset to restore power. AFCIs detect arc faults that cause electrical fires.
A doorbell transformer that buzzes is usually loose mounting, mechanical hum from worn coils, or a voltage mismatch from a new smart doorbell drawing more current than the old transformer can supply.
Inspect the home EV charger monthly: cable for cuts or chew marks, connector pins for corrosion, mounting for movement, GFCI for proper trip. Yearly: have an electrician inspect the breaker and dedicated circuit.
Once a year: replace aged smoke and CO alarms, check the fire extinguisher, clean the dryer vent, test the garage door auto-reverse, and find the water shutoff.
Between guest stays, the safety items come first: test the smoke and CO alarms, check the fire extinguisher, restock first aid, and check the HVAC filter.
