11 Home Electrical Safety Tips


Listen to your breaker.

A breaker that trips immediately after it's reset is telling you that there's an electrical problem. Sure, sometimes the breaker itself is to blame, and in some cases there may just be too large an electrical load operating on that circuit. But it's more likely that the breaker is tripping because there's a severe electrical problem. Keep pressing that breaker, and you're likely to cause a fire. 

Know when to fight and when to flee.

Firefighters recommend that if you have any doubt about fighting a fire, you're best bet is to get out of the house as quickly as possible. Once you're safely outside, call the fire department. If you decide that there's a reasonable chance that you can fight a fire and win, then stand your ground, but don't let the fire get between you and the exit. If you sense that the fire's going to overtake you and block your exit, get out. 

Never throw water on an electrical fire.

This will be obvious to many PM readers, but in the heat (ahem) of the moment, grabbing a bucket of water can seem tempting, if unreasonable. Water conducts electricity (this is why you don't want to be in a lake during a lightning storm), so throwing water on the fire could cause it to get larger. Instead, use your chemical fire extinguisher. 

Use your fire extinguisher effectively.

Firefighters recommend the time-honored PASS method: 

Pull the fire extinguisher's safety pin.
Aim the extinguisher nozzle at the base of the fire.
Squeeze the extinguisher's handle.
Sweep the extinguisher's nozzle in a side-to-side motion until the flames are out. 

Sure, it sounds easy, but let's hope you never have to use this advice. Start by paying attention to what the circuit breaker is telling you. If it trips immediately, evaluate the situation if you are electrically competent or call an electrician. Don't call Pat, though; he's already got enough to do. 

Aside from blatantly obvious electrical malfunctions that lead to flying sparks or circuit breakers that trip repeatedly, you should always keep a sharp eye cocked for more subtle telltale electrical-danger signs: 

Lights that flicker or that trip the circuit breaker

Cause: Loose wiring splice or a light fixture that's worn out and needs to be replaced.

Solution: Cut power to the fixture and investigate the supply wiring and the fixture itself. Replace wire connectors with new professional-grade types. Replace the fixture if suspect. 

Outlets with a faceplate that's warm to the touch

Cause: An overly large electrical load operating on that outlet, undersized wiring or a loose electrical splice. (Note: it's not unusual for dimmer switches, especially large ones, to be warm. Unless the switch face is actually too hot to touch, a warm dimmer is not a hazard in most cases)

Solution: Cut power and investigate. Look for a loose splice, melted connections, burned insulation. Repair as necessary. Also, evaluate wattage of device; it may be too large relative to supply wiring. Move device to another circuit, preferably one served by a 20-amp circuit breaker and 12-gauge wire. If condition persists, contact an electrician. 

Extension cords wrapped in electrical tape or with loose ends

Cause: Wear and tear has taken its toll on the cord.

Solution: Cut off damaged sections of cords; replace loose or damaged male/female ends. Replace severely damaged cords. 

Wobbly switches or outlet receptacles

Cause: Device is improperly mounted to the electrical box or the box itself has come loose from the stud.

Solution: Cut power. Remove faceplate and tighten mounting screws. Occasionally, overly long screws will not fully seat. Shorten screws with an electrician's multitool (a pair of pliers that strip wire, bend wire and cut screws ). Reinstall device. Otherwise, tighten connection of box to framing. 

Ceiling fans that slowly wobble

Cause: Fan is out of balance or may be installed on a box that's not listed for supporting a fan.

Solution: Balance fan or cut power and reinstall fan, checking for loose, damaged or missing hardware. If necessary, replace box. Use a retrofit/old-work box rated for fan installation (note: These are not to be confused with old-work boxes or other electrical boxes not listed for fan installation. Specialized retrofit boxes rated for fans tend not to be common hardware-store or home-center items. Visit an electrical supply house or use a Web-based supplier. One version is the Steel One Box manufactured by Arlington Products. (www.aifittings.com). 

GFCI outlets that trip repeatedly

Cause: A ground fault or a worn-out GFCI outlet receptacle.

Solution: Move appliance or tool to another GFCI and test. If GFCI trips, appliance or tool is suspect. If GFCI does not trip, electrical problems are likely. Cut power and investigate for damaged wire insulation, a loose splice or a small length of exposed wire making contact with a metal electrical box. If you don't find wiring or splice problems, replace the GFCI. If condition persists, contact an electrician. 

The beer fridge in the garage that occasionally gives you a small shock

Cause: Many an old refrigerator will have a tiny leakage current because of worn-out insulation on its internal wiring, especially if it has a defrost circuit. This phenomenon is well-known and can even be quite dangerous when the refrigerator is placed on an electrically conductive concrete floor, especially a floor that's damp with condensation.

Solution: Replace the refrigerator with a new energy-conserving model.

10 ways to winterize your home — now

1. Clean those gutters  
Once the leaves fall, remove them and other debris from your home's gutters -- by hand, by scraper or spatula, and finally by a good hose rinse -- so that winter's rain and melting snow can drain. Clogged drains can form ice dams, in which water backs up, freezes and causes water to seep into the house, the Insurance Information Institute says. 
As you're hosing out your gutters, look for leaks and misaligned pipes. Also, make sure the downspouts are carrying water away from the house's foundation, where it could cause flooding or other water damage.


2. Block those leaks
One of the best ways to winterize your home is to simply block obvious leaks around your house, both inside and out, experts say. The average American home has leaks that amount to a nine-square-foot hole in the wall, according to EarthWorks Group.



First, find the leaks: On a breezy day, walk around inside holding a lit incense stick to the most common drafty areas: recessed lighting, window and door frames, electrical outlets.
Then, buy door sweeps to close spaces under exterior doors, and caulk or apply tacky rope caulk to those drafty spots, says Danny Lipford, host of the nationally syndicated TV show "Today's Homeowner." Outlet gaskets can easily be installed in electrical outlets that share a home's outer walls, where cold air often enters.
Outside, seal leaks with weather-resistant caulk. For brick areas, use masonry sealer, which will better stand up to freezing and thawing. "Even if it's a small crack, it's worth sealing up," Lipford says. "It also discourages any insects from entering your home."

3. Insulate yourself
"Another thing that does cost a little money -- but boy, you do get the money back quick -- is adding insulation to the existing insulation in the attic," says Lipford. "Regardless of the climate conditions you live in, in the (U.S.) you need a minimum of 12 inches of insulation in your attic."
Don't clutter your brain with R-values or measuring tape, though. Here's Lipford's rule of thumb on whether you need to add insulation: "If you go into the attic and you can see the ceiling joists you know you don't have enough, because a ceiling joist is at most 10 or 11 inches."
A related tip: If you're layering insulation atop other insulation, don't use the kind that has "kraft face" finish (i.e., a paper backing). It acts as a vapor barrier, Lipford explains, and therefore can cause moisture problems in the insulation.

4. Check the furnace
First, turn your furnace on now, to make sure it's even working, before the coldest weather descends. A strong, odd, short-lasting smell is natural when firing up the furnace in the autumn; simply open windows to dissipate it. But if the smell lasts a long time, shut down the furnace and call a professional.
It's a good idea to have furnaces cleaned and tuned annually. Costs will often run about $100-$125. An inspector should do the following, among other things: 
Throughout the winter you should change the furnace filters regularly (check them monthly). A dirty filter impedes air flow, reduces efficiency and could even cause a fire in an extreme case. Toss out the dirty fiberglass filters; reusable electrostatic or electronic filters can be washed.

5. Get your ducts in a row 
According to the U.S. Department of Energy, a home with central heating can lose up to 60% of its heated air before that air reaches the vents if ductwork is not well-connected and insulated, or if it must travel through unheated spaces. That's a huge amount of wasted money, not to mention a chilly house. (Check out this audit tool for other ideas on how to save on your energy bills this winter.)
Ducts aren't always easy to see, but you can often find them exposed in the attic, the basement and crawlspaces. Repair places where pipes are pinched, which impedes flow of heated air to the house, and fix gaps with a metal-backed tape (duct tape actually doesn't stand up to the job over time).
Ducts also should be vacuumed once every few years, to clean out the abundant dust, animal hair and other gunk that can gather in them and cause respiratory problems.

6. Face your windows
Now, of course, is the time to take down the window screens and put up storm windows, which provide an extra layer of protection and warmth for the home. Storm windows are particularly helpful if you have old, single-pane glass windows. But if you don't have storm windows, and your windows are leaky or drafty, "They need to be updated to a more efficient window," says Lipford.
Of course, windows are pricey. Budget to replace them a few at a time, and in the meantime, buy a window insulator kit, Lipford and Broili recommend. Basically, the kit is plastic sheeting that's affixed to a window’s interior with double-stick tape. A hair dryer is then used to shrink-wrap the sheeting onto the window. (It can be removed in the spring.) "It's temporary and it's not pretty, but it's inexpensive (about $4 a window) and it's extremely effective," says Lipford.

7. Don't forget the chimney
Ideally, spring is the time to think about your chimney, because "chimney sweeps are going crazy right now, as you might have guessed," says Ashley Eldridge, director of education for the Chimney Safety Institute of America.
That said, don't put off your chimney needs before using your fireplace, Eldridge advises. "A common myth is that a chimney needs to be swept every year," says Eldridge. Not true. But a chimney should at least be inspected before use each year, he adds. "I've seen tennis balls and ducks in chimneys," he says.
Ask for a Level 1 inspection, in which the professional examines the readily accessible portions of the chimney, Eldridge says. "Most certified chimney sweeps include a Level 1 service with a sweep," he adds.
Woodstoves are a different beast, however, cautions Eldridge. They should be swept more than once a year. A general rule of thumb is that a cleaning should be performed for every ¼ inch of creosote, "anywhere that it's found." Why? "If it's ash, then it's primarily lye -- the same stuff that was once used to make soap, and it's very acidic." It can cause mortar and the metal damper to rot, Eldridge says.
Another tip: Buy a protective cap for your chimney, with a screen, advises Eldridge. "It's probably the single easiest protection" because it keeps out foreign objects (birds, tennis balls) as well as rain that can mix with the ash and eat away at the fireplace's walls. He advises buying based on durability, not appearance.
One other reminder: To keep out cold air, fireplace owners should keep their chimney's damper closed when the fireplace isn't in use. And for the same reason, woodstove owners should have glass doors on their stoves, and keep them closed when the stove isn't in use.

8. Reverse that fan
"Reversing your ceiling fan is a small tip that people don't often think of," says Lipford. By reversing its direction from the summer operation, the fan will push warm air downward and force it to recirculate, keeping you more comfortable. (Here's how you know the fan is ready for winter: As you look up, the blades should be turning clockwise, says Lipford.)

9. Wrap those pipes
A burst pipe caused by a winter freeze is a nightmare. Prevent it before Jack Frost sets his grip: Before freezing nights hit, make certain that the water to your hose bibs is shut off inside your house (via a turnoff valve), and that the lines are drained, says Broili. In climes such as Portland, Ore., or Seattle, where freezing nights aren't commonplace, you can install Styrofoam cups with a screw attachment to help insulate spigots, says Broili. 
Next, go looking for other pipes that aren't insulated, or that pass through unheated spaces -- pipes that run through crawlspaces, basements or garages. Wrap them with pre-molded foam rubber sleeves or fiberglass insulation, available at hardware stores. If you're really worried about a pipe freezing, you can first wrap it with heating tape, which is basically an electrical cord that emits heat.

10. Finally, check those alarms
This is a great time to check the operation -- and change the batteries -- on your home's smoke detectors. Detectors should be replaced every 10 years, fire officials say. Test them -- older ones in particular -- with a small bit of actual smoke, and not just by pressing the "test" button. Check to see that your fire extinguisher is still where it should be, and still works.
Also, invest in a carbon-monoxide detector; every home should have at least one.
