-
Only
use UL or FM approved extension cords.
-
Make
sure the extension cord is large enough to carry the
intended load. (The
thicker the cord, the greater the load it should be able
to carry without overheating.)
-
Inspect
the cord for damaged insulation, splices, or loose plugs
before using. Never
use an extension cord that has any of these conditions.
-
Do
not overload outlets! Use surge protectors if multiple
outlets are needed.
-
Immediately
replace any broken bulbs that have exposed filaments.
-
Never
use electric lights on old metal artificial trees.
-
Don't
run cords through doorways or under rugs. The insulation
on the cords can become damaged if the door closes on the
cord, or if people step on it under the rug, causing a
potential fire and/or shock hazard.
-
Match plugs with outlets. Don't force a 3-pronged plug
into a 2-pronged outlet or extension cord.
