If you use extension cords, make sure that you keep them out of the way of kids and others. If they are on the floor in a building, you can tape them to the floor, so they do not move or trip people. Low decorations or dangling items outdoors can be less of a problem for visitors if you form a protective barrier with straw bales or tombstones. Use candles that are battery-powered instead of real ones for putting inside jack-o-lanterns and solar lights for outdoor lighting for paths. Safe holidays and events are much more fun for everyone.
