Avoid Electrical Fires Before they Start!

Electricity causes more than 40,000 fires every year in the United States, resulting in hundreds of injuries and deaths. Electrical fires kill more than 750 people and cause more than $1 billion in property damage annually, according to the U.S. Consumer Product Safety Commission (CPSC).

The top electrical safety hazards include electrical fires caused by aging wiring, misuse of surge suppressors, and shocks and electrocutions from  wiring systems and large pieces of equipment.

Extension cord fires outnumber fires beginning with attached or unattached power cords by more than 2-to-1. Employers and employees need to remember that an important aspect of workplace electrical safety is properly using extension cords, power strips, and surge protectors.

Other sources of electrical accidents are faulty or defective equipment, unsafe installation, or misused equipment. Follow these guidelines to help keep your workplace safe:

General Electrical Safety Tips

  • Replace or repair loose or frayed cords on all electrical devices.
  • Avoid running extension cords across doorways or under carpets.
  • In areas with small children, such as child care centers, electrical outlets should have plastic safety covers and be tamper resistant.
  • Follow the manufacturer’s instructions for plugging an appliance into a receptacle outlet.
  • Avoid overloading outlets. Consider plugging only one high-wattage Power stripsappliance into each receptacle outlet at a time. If the circuit breaker for that receptacle is doing its job, it will trip if the circuit becomes overloaded.
  • If outlets or switches feel warm, shut off the circuit and have them checked by a licensed electrician.
  • Avoid using “cube taps”, power strips, and other devices that allow you to plug multiple appliances into a single receptacle.

Outlet Safety

Receptacles (properly known as “receptacle outlets”) are perhaps the most commonly used and least thought of devices in the workplace.  And now everyone has cell phone and other mobile device chargers to plug into a limited number of outlets.

Here are some tips to keep your workplace’s outlets safe:plug in

  • Check outlets regularly for broken parts, overheating, loose connections, and corrosion. Consider having an electrical inspection performed by a qualified, licensed electrician to determine the integrity of your outlets and your entire electrical system.
  • Check for outlets that won’t hold a plug. Tired receptacles can lead to arcing faults and fires.
  • Hot is not OK. If a receptacle or switch wall plate is discolored or hot to the touch, immediately shut off power to the circuit and have it checked by a licensed electrician.
  • Replace missing, damaged, or broken wall plates.

Power Strips and Surge Suppressors
Power strips allow employees to plug more products into the same outlet, which can be handy, but can also be a safety hazard. Power strips, aka outlet strips, don’t provide more power to a location, just more access to the same limited capacity of the circuit to which it is connected.

  • Surge suppressors do help to protect connected equipment, but are not an absolute guarantee. Many come with dollar-figure guarantees for connected equipment damaged in a surge. Please do yourself a favor and read the fine print!
  • Any circuit likely also still serves a variety of other outlets and fixtures, in addition to the items plugged into the power strip. When using power strips and surge suppressors, keep these safety principles in mind:
  • Don’t overload the circuit. Know the capacity of the circuit and the power requirements of all the electrical items plugged into the power strip and into all the other outlets on the circuit, as well as any light fixtures on the circuit. We have seen power strips literally explode when faulty equipment was plugged into them.
  • A heavy reliance on power strips means that you probably don’t have surge protectorenough receptacles. Have a qualified electrician install additional outlets where needed.
  • Surge suppressors can manage the small surges and spikes sometimes generated by turning equipment on and off. They may even protect against a large surge generated from outside sources like lightning or problems along the power lines to the business. In the event of a large surge or spike, the surge suppressor only protects your equipment one time, and then it will likely need replacing. These devices basically sacrifice themselves to protect connected equipment. Check them regularly for the “happy light,” usually green, which shows that protection is enabled.
  • Consider purchasing surge suppressors with cable and phone jacks to provide the same protection to your phone, fax, computer, TV, and so on.
  • Not all power strips are surge suppressors, and not all surge suppressors can handle the same load and events. There are also surge protective devices that mount to or inside a breaker panel. Ask a licensed electrician for advice to be sure the equipment you buy matches your needs.

Follow These Fall Safety Tips!

The Electrical Safety Foundation International (ESFI), reminds you to keep electrical safety in mind as the cooler fall weather moves many activities back indoors. The following safety tips will help you stay safe during the change of seasons:
  • Safely store warm weather tools like lawn mowers and trimmers. 
  • Check cold weather tools, such as leaf and snow blowers, along with their power cords, for unusual wear and tear. 
  • Repair or replace worn tools or parts right away.
  • Unplug and safely store battery chargers that won’t be in use again until spring.
  • Use only weatherproof electrical devices for outside activities. Protect outdoor electrical devices from moisture.
  • Make sure electrical equipment that has been wet is inspected and reconditioned by a certified repair dealer.
  • Keep dry leaves swept away from outdoor lighting, outlets and power cords. 
  • Make sure electric blankets are in good repair and certified by an independent testing lab such as UL, CSA or ETL. 
  • Power cords should not be frayed, cracked or cut. 
  • Do not tuck your electric blanket under mattresses or children, and do not put anything, such as comforters or bedspreads, on top of the blanket while it is in use. 
  • Never allow pets to sleep on an electric blanket.

More Home Fires Occur in Winter

Home-FireWith winter’s coldest months upon us, we ask that people be aware of electrical fire hazards.

In an average year, heating is the cause of 17 percent of structure fires; however, in winter, especially during the coldest months, heating fires jump to 27 percent of structure fires, according to the U.S. Fire Administration.

Recognize Signs of Trouble

Be alert and learn to recognize signs of electrical trouble waiting to happen. Some warning signs that could lead to an electrical fire are:

  • Lights flicker for no apparent reason
  • You wiggle a switch and it feels “floppy” in your hand and/or the lights flicker or go on and off
  • The light switch doesn’t turn the lights on or – even worse – won’t turn them off
  • An unusual smell
  • Discolored receptacles, switches or other electrical devices
  • Sparks or noises (especially like “frying eggs)
  • Frayed wires or loose connections
  • Overloaded outlets, extension cords or surge protectors
  • Circuit breakers trip – and be especially concerned if they won’t reset!

If you see any of these signs of electrical problems, call an electrician immediately. A qualified electrician can identify possible causes, such as short or overloaded circuits, improperly-rated fuses and breakers, and not having ground-fault protection where it’s needed to protect against shock hazards.

Little Sparkie Electric offers safety checks as part of our services, and we see scary things just about every day. We check circuit breakers and wire connections, look for deterioration and corrosion, run tests to help ensure that electrical equipment is functioning correctly, and make recommendations to help ensure safety.

And you should always check to make sure your smoke alarms are working; we also install hard-wired alarms to comply with local electrical codes.

Winter Storms Can Cause Extra Hazards

Winter storms such as those the Eastern Seaboard has experienced in recent years, can cause additional hazards. These include:

  • Alternative heating devices such as space heaters, being used incorrectly.
  • Damaged or downed utility lines.
  • Water damaged appliances and utilities can be electrically charged.
  • Frozen water pipes can burst and cause safety hazards.
  • Leaking gas lines, damaged or leaking gas propane containers, and leaking vehicle gas tanks may explode or ignite.
  • Generators are often used during power outages, but if they’re not properly used and maintained they can be hazardous.

We always advise people to always follow manufacturers’ instructions and guidelines. Always use a generator or other fuel-powered machines outside of the home in a well-ventilated location, as carbon monoxide fumes are odorless and can quickly overwhelm you indoors.
