Electrical Safety

Have electrical work performed by licensed professionals. Appliances and electrical cords should be certified by underwriters laboratory (U.L.).

Safety Tips

  • Avoid plugging in more than one plug per outlet. Failure to do so may lead to overloading of the circuit.
  • Discard any item with damaged/frayed wiring.
  • The following are extremely hazardous:
    • Running wiring under carpets, rugs, or furniture
    • Pinching wires when moving furniture
    • Daisy chains; connecting multiple extension cords to extend farther
    • Piggybacking: plugging a power strip into another power strip connected to one outlet.

Extension Cord Safety

Extension cords are intended as temporary wiring solutions and not for permanent use.

  • Use extension cords according to the U.L. rating.
  • Never remove an extension cord’s grounding pin to fit into a two-prong outlet.
  • Never use indoor extension cords outdoors.

WARNING: If the extension cord becomes hot while using it, immediately unplug the appliance.

Lithium-ion Batteries

Handle batteries carefully, and only use the battery designed for the device.

  • Keep lithium-ion batteries at room temperature.
  • Avoid excessive charging, direct sunlight, and a hot/humid environment.
  • Store separately; away from anything that can catch fire, including other lithium-ion batteries.
  • Discontinue use if the battery exhibits the following:
    • odor
    • drop damage
    • leaking
    • change in color or shape
    • too much heat
    • odd noises


  • Use charging cords and blocks approved by the manufacturer for the specific device model.
  • Replace cords that are damaged, frayed, or sticky to the touch.
  • Charge devices, especially cell phones, on a hard, nonflammable surface.
    • Never charge devices on beds, couches, or cloth.
    • Charge in a cool, ventilated area. Avoid direct sunlight and heat.
  • Avoid excessive charging.
  • Contact the manufacturer for more information.


  • Avoid putting rechargeable batteries in the trash or in piles. Recycling is the best option.
