Adventure & Obstacle Sports Expert, Ian Adamson appeared on Good Morning America to discuss zip line safety, following an incident where a 6-year-old's harness failed and the child fell 40 feet.
"Some of the worst injuries, they can happen at speed. Look to see if before you go down a zipline, see if there’s anyone on it. The guides sometimes are not quite aware, so the fallback is yourself.
[Zip lines] are not regulated. There are standards, and the standards are quite good, but not everyone complies and they’re not mandatory, so just beware."
