12 Days of Holiday safety - Tip #4
Only use outdoor and indoor lights as indicated on their packaging.
On the fourth day of safety, we remind you to only use lights tested for safety by a nationally recognized testing laboratory. Lights for both indoor and outdoor usage must meet different standards that testing laboratories can verify. Before using, be sure to check each set of lights – whether new or old – for broken or cracked sockets, frayed or bare wires, or loose connections. Throw out damaged sets and do not use electric lights on a metallic tree. Check outdoor lights for labels showing the lights have been certified for outdoor use, and only plug them into a ground-fault circuit interrupter (GFCI)-protected receptacle or a portable GFCI.
