Quick answer
Use lights and cords rated for outdoor use, plug into GFCI-protected outlets, don't overload circuits, and use a sturdy ladder with someone holding it.
Equipment
- Check labels for outdoor use
- Inspect strands for cracked sockets or frayed wires
- Use plastic clips, not nails or staples
- Use timers so lights aren't on all night
Ladders and Rooflines
Most holiday-lighting injuries are falls. Set ladders on firm, level ground and avoid working on icy or windy days.
Oklahoma Weather
Wind and ice can loosen strands. Secure lights firmly and check them after storms.
