Did a large outdoor event a couple of weeks ago on a football field. A/C was about 150' from me across part of the field. Past experience showed that this same area would see considerable foot traffic so I marked the cable with numerous orange cones along it's route.
As the event unfolded through the night, those orange cones attracted kids like moths to lightbulbs. Instead of parents keeping the kids away, I actually watched parents "supervising" their kids while they ran around the cones, moved them, threw them at each other, etc........
I had one paticular cone that marked the location where I had tied two 10ga. cables together. The cone sat directly upon the connectors to protect them from foot traffic. I watched one 4-5 year old kid remove this cone and start playing with the connectors while his mother was standing there watching!!!! I left the board and hustled over to this kid to stop him from going any further. I explained to his mom that she needed to find somewhere else for him to play.
I ask myself, would this woman have permitted her child to play with an active extention cord in her own home? (maybe?) I'm working on a locking box as an answer to this issue as it seems to come up repeatedly. I really thought an average adult could see the potential danger here and do what parents should do. Darwin wasn't wrong.
